Geofenced Time Tracking Built for Construction Crews

Geofenced time tracking that keeps construction crews honest

Projul’s geofenced time tracking gives you real-time visibility into where your crew is clocked in and whether they’re actually on the right job site. Over 5,000 contractors use Projul’s GPS time tracking to cut time theft, speed up payroll, and get accurate labor costs on every project.

Projul’s geofenced time tracking verifies crew clock-ins with GPS boundaries around each construction job site, catching buddy punching and time padding automatically. Labor hours flow directly into job costing and QuickBooks. Projul offers flat-rate pricing with no per-user fees for construction companies of all sizes.

Set a virtual boundary around each job site. When a crew member clocks in, Projul’s GPS confirms they’re inside that boundary. If they’re not, you get an alert. It’s that simple.

How geofencing stops time theft

Time theft costs contractors thousands of dollars every year. Someone clocks in from the parking lot of a gas station. A crew member has a buddy punch them in while they’re still 20 minutes away. Another person logs 8 hours but left the site at 3 PM.

Geofenced time tracking puts a stop to all of it.

When you set up a geofence in Projul, you’re drawing a line around the job site. The app checks GPS coordinates every time someone clocks in or out. If a worker tries to clock in from outside the fence, you’ll know about it immediately. And because Projul runs as a native app on iOS and Android, the GPS tracking is accurate and runs in the background without your crew having to do anything extra.

Here’s what that looks like in practice. You’re running a remodel in Park City and a new build in Draper. Your drywall crew says they started at 7 AM on the Park City job. With geofencing, you can confirm that’s true. No guessing, no arguments, just GPS data tied to their time entry.

Whether you’re a roofing contractor, an electrical contractor, or a general contractor, switching from paper timesheets to geofenced time tracking typically reveals 5-10% of labor hours were inaccurate. On a crew of 15, that’s real money.

The real cost of buddy punching and time padding

Let’s put some numbers behind time theft so you can see what it actually costs your business.

Say you have a crew of 12 field workers, each billing at an average loaded cost of $35/hour. If each worker pads their time by just 15 minutes a day, either clocking in early from home, taking a long lunch, or having a buddy punch them in, that’s 3 hours of phantom labor every day across the crew.

At $35/hour, 3 phantom hours a day costs you $105. Over a 5-day work week, that’s $525. Over a year, that’s $27,300 in labor costs for work that didn’t happen.

And 15 minutes of padding per worker is a conservative estimate. Many contractors who switch to geofenced time tracking discover the problem was much worse than they thought. Some find 30 to 45 minutes of daily time inflation per worker, which doubles or triples those numbers.

Geofencing doesn’t just reduce time theft. It eliminates the environment where time theft can happen. When every clock-in is verified against a GPS boundary, there’s no gray area. Your crew is either on the site or they’re not. The data speaks for itself.

GPS verification: how it actually works

The technology behind geofenced time tracking is straightforward, but it’s worth understanding so you know what your crew experiences.

When you create a project in Projul, you set the job site address. Projul draws a virtual boundary (the geofence) around that location. You can adjust the size of the boundary to account for large job sites, multiple buildings, or nearby staging areas.

When a crew member opens the Projul app and taps clock in, the app reads the GPS coordinates from their phone. It compares those coordinates to the geofence boundary for the project they’re clocking into. If they’re inside the fence, the time entry records normally. If they’re outside the fence, the system flags it and you get an alert.

The same check happens at clock out. If someone tries to clock out from a location that isn’t the job site, the system notes it. This catches workers who leave early but clock out later from home.

All of this runs on the phone’s built-in GPS. There’s no extra hardware to buy, no tablets to mount at job sites, and no kiosks to maintain. Your crew uses the same phone they already carry. They download the Projul app from the App Store or Google Play, log in, and they’re ready to go.

Automatic clock in/out at job sites

Beyond manual clock-in verification, Projul’s geofencing can alert workers when they arrive at or leave a job site. This gives crew members a reminder to clock in when they arrive and clock out when they leave, reducing forgotten punches and after-the-fact corrections.

For foremen managing multiple workers, this is a big deal. Instead of reminding everyone to clock in at the start of the day and clock out at the end, the app handles it. Workers get prompted when they enter the geofence. Forgotten clock-ins that used to require manual corrections drop significantly.

This also helps with time entries that need to be split across multiple job sites in a single day. If a worker drives from the morning job to the afternoon job, the geofence change prompts them to clock out of one and into the other. You get accurate time allocation to each project without anyone having to remember which hours went where.

Timesheet accuracy your accountant will love

Accurate timesheets make everything downstream better. Payroll is faster. Job costing is reliable. Invoice line items match the actual work. Client disputes about labor charges drop to nearly zero.

With geofenced time tracking, every time entry comes with GPS data proving the worker was at the right location. There’s no question about whether the hours are real. This is especially valuable for contractors who bill time and materials, where labor hours directly determine the invoice amount.

Here’s what accurate timesheets give you:

Faster payroll processing. Instead of collecting paper timesheets from three foremen, cross-referencing them against schedules, and fixing discrepancies, you approve digital timesheets that are already verified by GPS. Your office manager goes from spending half a day on payroll to finishing it in under an hour.

Reliable job costing. When every hour is tracked to the right project and verified by location, your budgeting data is trustworthy. You know exactly how much labor went into each phase of each project.

Fewer client disputes. For T&M billing, GPS-verified timesheets give clients confidence that the hours on the invoice are accurate. When a client questions a labor charge, you have GPS data to back it up.

Better estimating. When your historical labor data is accurate, your future estimates get more precise. You know exactly how long similar projects took in the past, so you can bid the next one with confidence.

Payroll integration through QuickBooks

Projul’s time entries sync directly to QuickBooks Online and QuickBooks Desktop. Approved time logs push automatically, so your bookkeeper or office manager doesn’t re-enter a single hour.

The payroll workflow looks like this:

1. Your crew clocks in and out using the Projul app with GPS verification
2. Time entries appear in Projul tied to the correct project and task
3. Your PM or office manager reviews and approves the time entries
4. Approved entries sync to QuickBooks automatically
5. Your bookkeeper runs payroll from QuickBooks with accurate, verified data

The entire process from field clock-in to payroll-ready data happens without anyone retyping hours into a spreadsheet. For contractors who were spending hours every pay period on manual timesheet processing, this alone pays for the software.

Crew accountability without micromanagement

Nobody wants to be the boss who’s constantly checking up on their crew. But when you’re running 5 or 10 jobs at the same time, you need to know that people are where they’re supposed to be.

Geofenced time tracking gives you that accountability without the awkward conversations. You’re not calling job sites to check on people. You’re not driving by to see if trucks are parked there. The GPS data tells you what you need to know, quietly and automatically.

This changes the dynamic with your crew. Instead of an honor system that breeds suspicion, you have a verification system that builds trust. The workers who show up on time and put in their hours have nothing to worry about. The ones who were padding their time adjust their habits because they know the data is there.

Most contractors find that simply implementing geofenced time tracking improves crew punctuality and reduces time disputes, even before they take any specific action based on the data. The existence of GPS verification creates accountability by default.

Fraud prevention beyond time theft

Geofenced time tracking prevents more than just buddy punching and time padding. It also catches these common problems:

Wrong job site billing. A worker clocks in at the Smith project but actually spends the day at the Jones project. Without geofencing, the Smith project absorbs labor costs it shouldn’t, and the Jones project’s budget looks better than it is. GPS verification ties every hour to the correct location.

Ghost employees. In rare but costly cases, a foreman creates time entries for workers who aren’t actually on the crew or aren’t on the site. GPS data makes this impossible because every time entry requires a physical device at the job site location.

Overtime manipulation. Without location data, it’s hard to verify if overtime hours were actually worked on site. Geofenced time tracking confirms that overtime hours were spent at the job location, not clocked from home.

Multiple job site support

Construction companies don’t run one job at a time. You might have 5, 10, or 20 active projects across your metro area. Projul’s geofencing supports every one of them simultaneously.

Each project gets its own geofence with its own boundary. When a crew member clocks in, the app knows which site they’re at and ties the time to the correct project. If a worker visits two sites in one day, each visit gets its own time entry linked to the right job.

This is critical for accurate job costing. When labor hours get charged to the wrong project, your budget data is useless. You think one job is over on labor when it’s actually another job’s hours that got miscoded. Geofencing eliminates that problem because the GPS determines which project gets charged, not the worker’s memory of which job code to enter.

For contractors who move crews between sites daily, this tracking is automatic. No paperwork. No phone calls. No end-of-week guessing about who was where on which day.

Why geofencing requires a native app

Geofencing depends on direct access to your phone’s GPS hardware. The app needs to run background location services to detect when a crew member enters or leaves a job site boundary. This is only possible with a native app installed from the App Store or Google Play.

Some construction platforms use browser-based apps (called Progressive Web Apps or PWAs) instead of native apps. A browser can request your location once when you tap a button, but it can’t track your position in the background. That means no automatic clock-in when you arrive at the site, no alerts when someone clocks in from the wrong location, and no reliable geofence boundaries.

Projul’s native iOS and Android apps have full GPS access for geofencing. Your crew downloads the app, and geofencing works automatically. No workarounds, no browser tricks. Just accurate location-based time tracking.

Track time fast from the field

Projul replaces paper time cards with a digital time clock built for construction. Your crew opens the app, taps clock in, and they’re done. The GPS does the rest.

From the office side, you see a live feed of who’s clocked in, where they are, and what project they’re working on. If someone’s running late or hasn’t clocked in yet, you know immediately instead of finding out at the end of the week.

Time entries automatically attach to the correct project and task. That means your time tracking data flows into job costing without anyone touching a spreadsheet. And when it’s time to run reports, everything’s already organized by project, worker, and date.

Automated job costing from tracked hours

Projul automatically ties time logs to specific projects and tasks so you always know your bottom line. Set labor rates for each worker, and Projul calculates real-time labor costs as hours are logged.

When labor costs start creeping past your estimate, you’ll see it in the numbers before it’s too late. That’s when you know it’s time for a change order instead of eating the difference.

Track time to specific projects and tasks for real-time labor costs. Know your profit margins on every job, not just at the end when it’s too late to do anything about it.

Turn tracked hours into invoices

Your crew’s hours flow right into service invoicing. Pick the time entries, generate the invoice, and send it. No manual entry, no missed billable time. For time-and-materials jobs, this alone can recover thousands in unbilled hours every year.

The GPS-verified data adds credibility to your invoices. When a client sees itemized time entries backed by location data, there’s less pushback on labor charges. They know the hours are real because the data proves it.

Know your labor costs before they kill your margins

Geo-fenced time data feeds directly into budgeting so you can see real-time labor costs against your budget. Pair it with your schedule to know exactly who’s where and what it’s costing you.

And when you need the full picture, Projul’s reporting tools pull all that time and cost data into reports you can actually use. WIP reports, labor cost breakdowns, profitability by project. The data’s already there because your crew tracked it from the field.

Setting Up Geofences: Practical Tips From the Field

Getting geofenced time tracking running is straightforward, but a few details make the difference between a system your crew actually uses and one they fight against.

Size your geofences for the real job site, not just the building. A tight fence around the structure sounds logical, but your crew parks across the street, stages materials in the side lot, and meets at the trailer 200 feet from the foundation. Set the boundary wide enough to cover the full work area including parking, staging, and portable facilities. Most contractors find a 300-to-500-foot radius works well for residential jobs and 800-to-1,200 feet for commercial sites.

Brief your crew before you flip the switch. The biggest pushback on GPS time tracking comes from surprises. Tell your team what the app does, why you are doing it, and what happens when someone clocks in outside the fence. When crews understand it is about accurate job costing and not surveillance, adoption goes smoother. Have your foremen demo the clock-in process on day one.

Handle multi-site days correctly. If your workers visit two or three sites in a single day, make sure they know to clock out at one site and clock in at the next. Projul prompts them when they cross a geofence boundary, but building the habit early prevents messy timesheets that need manual cleanup. This is especially common for plumbing contractors and HVAC companies running service calls across town.

Review flagged entries weekly, not monthly. The alert system catches clock-ins outside the fence, but those flags only help if someone looks at them. Set aside 15 minutes every Friday to review flagged time entries. Most will have simple explanations, like a worker who parked one street too far away, but catching the real problems early keeps your job costing data clean. Pair this review with your project management check-in and you will spot labor issues before they hit your margins.

What Is Geofencing and How Does It Work for Time Tracking?

If you have ever drawn a circle on a map, you already understand geofencing. That is really all it is. You pull up a map of your job site inside Projul, draw a virtual fence around the property, and tell the system “this is where work happens.” From that point forward, every time a crew member’s phone crosses that boundary, the app knows about it.

When one of your guys drives up to the job site in the morning and steps out of his truck, his phone’s GPS registers that he just crossed the geofence boundary. The Projul app prompts him to clock in. He taps the button, and his time starts recording - tied automatically to that specific project. No scrolling through job codes, no writing down start times on a crumpled piece of paper, no texting the foreman to say he showed up.

At the end of the day, the same thing happens in reverse. He walks back to his truck, crosses the geofence boundary on his way out, and the app reminds him to clock out. Tap, done. His hours for that project are logged, GPS-verified, and ready for payroll.

The buddy punching problem disappears overnight

Buddy punching is one of those problems every contractor knows about but few want to talk about openly. One guy is running late, so he calls his buddy who is already on site and asks him to clock in for him. It happens constantly on crews that use paper timesheets or basic time clock apps without location verification.

With geofencing, buddy punching is physically impossible. The clock-in has to come from a phone that is actually standing inside the geofence boundary. Your late worker’s buddy can tap away on his own phone all he wants - the system will only record a clock-in for the device that is physically present at the site. Each crew member clocks in on their own phone, from their own account, and the GPS proves they were there.

This is not about catching people in a gotcha moment. It is about removing the gray area entirely. When the system handles verification automatically, nobody has to feel awkward about it. There is no accusation, no confrontation, no trust issues. The fence does the checking, and everyone moves on with their day.

No more forgotten clock-ins

Every foreman has dealt with this: it is Wednesday afternoon and someone realizes they forgot to clock in on Monday morning. Now you are trying to reconstruct hours from memory, asking other crew members what time the guy showed up, and manually entering a time card that is probably off by 15 or 20 minutes.

Geofencing kills this problem. The app prompts workers to clock in when they arrive. If someone ignores the prompt and starts working without clocking in, the GPS data still shows when their phone entered the geofence. Your office manager can see the gap and correct it with actual data instead of guesswork.

Over time, the prompt system trains your crew to clock in and out consistently. After a week or two, it becomes muscle memory - phone buzzes when you get to the site, you tap the button, you get to work. The days of chasing down forgotten time entries on Friday afternoon are over.

No more paper timesheets

Paper timesheets are a liability for construction companies. They get lost in truck cabs. They get soaked in the rain. The handwriting is illegible. Two different people write down different start times for the same morning. And someone in the office has to manually enter all of it into your accounting system, introducing yet another opportunity for errors.

Geofenced time tracking replaces that entire mess with a system that runs on the phone your crew already carries. Every clock-in and clock-out is digital, GPS-verified, and automatically attached to the right project. There is nothing to lose, nothing to decipher, and nothing to re-enter. The data goes straight from the job site to your office dashboard to your payroll system.

For contractors who have been running paper timesheets for years, the switch feels like going from a flip phone to a smartphone. You wonder how you ever operated the old way.

How the GPS technology works behind the scenes

You do not need to understand the technical details to use geofencing, but knowing the basics helps when you are explaining it to your crew or evaluating different software options.

Your crew members’ phones have GPS chips built into them. These chips communicate with satellites to determine the phone’s location within a few feet. When the Projul app is installed, it requests permission to access location services. Once granted, the app can check the phone’s GPS coordinates whenever someone interacts with the time clock.

The geofence itself is just a set of GPS coordinates stored on Projul’s servers. When a crew member taps clock in, the app compares the phone’s current GPS coordinates against the stored geofence boundary for that project. If the coordinates fall inside the boundary, the clock-in proceeds normally. If they fall outside, the system flags it.

This all happens in a fraction of a second. Your crew member taps the button and their time starts recording. They do not see any of the GPS math happening behind the scenes. From their perspective, it is just a simple clock-in button that works exactly like any other time clock app - except this one actually proves they were at the job site.

The app does not track your crew’s location continuously throughout the day. It only checks GPS coordinates at the moment of clock-in and clock-out. This is an important distinction for privacy, which we will cover in more detail below.

Why Geofenced Time Tracking Pays for Itself

Labor is the single biggest expense on most construction projects. Depending on the trade and the type of work, labor typically runs 30% to 50% of total project costs. On a $500,000 commercial job, that means $150,000 to $250,000 is going to labor. On a $100,000 residential remodel, $30,000 to $50,000 is payroll.

When that much money is at stake, even small inaccuracies in time tracking add up to serious dollars. And the truth is, most contractors are losing more to time inaccuracy than they realize.

The math on 15 minutes of daily padding

We covered this earlier with a 12-person crew example, but let’s look at it from a different angle. Say you run a crew of 8 field workers. Each one pads their time by an average of 15 minutes per day. Maybe they clock in from the truck while they are still grabbing coffee down the street. Maybe they take an extra-long lunch. Maybe they clock out 10 minutes after they actually stop working.

That is 2 hours of phantom labor per day across the crew. At an average loaded cost of $40/hour (including workers’ comp, payroll taxes, and benefits), that is $80 per day. Over a 5-day work week, $400. Over 50 working weeks in a year, $20,000.

Twenty thousand dollars. Gone. Not to materials. Not to equipment. Not to overhead that keeps the lights on. To time that nobody actually worked.

Now scale that to a 20-person crew and the number is $50,000 per year. Scale it to 15 minutes becoming 25 minutes of padding (which is common on crews without any location verification), and you are looking at $33,000 for the 8-person crew and over $80,000 for the 20-person crew.

Projul costs $4,788 per year with no per-user fees. The math is not even close. You recover the cost of the software in the first month - sometimes the first week.

Accurate time means accurate job costing

Time padding does not just waste money on payroll. It corrupts your job costing data, which means it corrupts your future bids.

Here is how the damage spreads. Your crew logs 10% more hours than they actually work on a bathroom remodel. Your job costing report says the remodel took 320 labor hours when it really took 290. Next time you bid a similar bathroom remodel, you estimate 320 hours because that is what your historical data shows. You price the job higher than it should be, which means you either lose the bid to a competitor or you win it and build in a hidden cushion that makes your true profit picture unclear.

Either way, your estimating is based on bad data. And every future bid that references that project carries the same inflation forward. Over time, your estimates drift further and further from reality.

Geofenced time tracking breaks that cycle. When every hour is GPS-verified, your labor data reflects what actually happened on the job. Your job costing is accurate. Your budgets are based on real numbers. And your future bids are priced on truth instead of inflated timesheets.

This is where geofencing pays for itself twice over. First, you save money by eliminating phantom labor hours. Second, you make more money by bidding more accurately on future work. Contractors who bid on tight data win more jobs at better margins than contractors who bid on guesswork.

The hidden cost of timesheet arguments

There is another cost that does not show up on any financial report: the time you and your office manager spend arguing about timesheets.

Every pay period, someone’s hours do not match the schedule. Someone claims they worked a Saturday that nobody approved. Two workers have different start times on the same day. The foreman’s notes do not match the office’s records.

These disputes eat up hours of administrative time. Your office manager is on the phone with foremen. You are pulled into conversations about who showed up when. And in the end, you usually just split the difference because there is no way to know what actually happened.

GPS-verified time entries eliminate these arguments. The data is the data. The worker clocked in at 7:03 AM inside the geofence and clocked out at 3:32 PM inside the geofence. There is nothing to argue about. Your office manager processes payroll from clean, verified records instead of mediating disputes.

Labor cost visibility in real time

When your time tracking is accurate and automatic, you can see labor costs accumulating on each project in real time. Not at the end of the week. Not at the end of the month when the damage is already done. Right now, today, while there is still time to do something about it.

If your framing crew is burning through budgeted hours faster than expected, you see it on day three instead of day fifteen. That gives you time to adjust - pull a worker, talk to the foreman about efficiency, or start the change order conversation with the client before the overage gets out of hand.

This kind of real-time labor visibility is only possible when your time data is flowing in automatically from the field. Paper timesheets that show up on Friday give you a rearview mirror. Geofenced time tracking gives you a dashboard.

What about the workers who are already honest?

Here is a fair question: “Most of my crew is honest. Why should I make everyone deal with geofencing for the few bad apples?”

The answer is that geofencing actually benefits your honest workers the most. The guys who show up on time every day and put in their full hours? They are already doing the right thing. Geofencing just proves it. No more being lumped in with the workers who pad their time. No more suspicion when the numbers do not add up. Their GPS data speaks for them.

And here is the other side of it. Your honest workers already know who the time-padders are. They see the guy who rolls in 20 minutes late every morning but logs a full start time. It bothers them. Geofencing levels the playing field and that actually improves crew morale.

Setting Up Geofences for Your Job Sites

One of the biggest concerns contractors have about new software is setup time. You are already stretched thin running jobs, managing crews, and keeping the office organized. The last thing you need is a system that takes hours to configure.

Setting up a geofence in Projul takes about 2 minutes per job site. Here is exactly how it works.

Step 1: Open the project and go to the map

When you create a new project in Projul (or open an existing one), you will see the job site address on the project details screen. Projul uses that address to place a pin on the map. Click the geofence option and you will see the map view with your job site centered.

If you are already managing your projects through Projul’s project management tools, the address is already in the system. You do not need to enter it again. The geofence setup pulls from the project details you have already filled in.

Step 2: Draw the fence

The map shows a circular boundary around the job site pin. You can drag the edges to adjust the radius. For a typical residential job, a 300-to-500-foot radius covers the house, the driveway, the material staging area, and nearby parking. For a larger commercial site, bump it up to 800 or 1,200 feet to cover the full property.

You do not need to be precise down to the foot. The point is to create a boundary that covers everywhere your crew might reasonably be while working on that job. If you have a large site with work happening in multiple areas, set the fence wide enough to cover all of them.

Some contractors ask whether they can draw custom shapes instead of circles. For most jobs, a circle works fine. The radius approach is fast to set up, easy to understand, and covers the job site without overcomplicating things.

Step 3: Set the radius and save

Once you have the boundary where you want it, save the geofence. That is it. The fence is now active for that project. Any crew member assigned to that project will get GPS verification when they clock in or out.

You can always come back and adjust the radius later if you find it is too tight or too wide. Maybe you set it tight and a few workers keep getting flagged because they park across the street. Just widen the fence a bit and the problem is solved.

Step 4: Assign your crew

If you have already assigned workers to the project through Projul’s scheduling tools, they are automatically covered by the geofence. When they open the app and go to clock in for that project, the GPS check happens automatically.

For new workers or subs who join the project mid-stream, just add them to the project in Projul and they are inside the system. No separate geofence setup needed per person. The fence is tied to the project, not the individual.

What happens when cell service is spotty

Construction sites are not always in areas with great cell coverage. Maybe you are building a custom home in the mountains. Maybe the commercial site is in an industrial area with weak signal. Maybe the basement level of a remodel is a dead zone.

Projul handles this. The app records the clock-in locally on the phone, including the GPS coordinates at the time of the punch. When the phone reconnects to cell service or Wi-Fi, it syncs the time entry to Projul’s servers. Your office sees the entry with full GPS data, just with a slight delay.

This means your crew does not need to stand outside holding their phone in the air trying to get a signal before they can start work. They clock in, the app saves it locally, and the data catches up when connectivity returns. For contractors working in rural areas or inside structures with poor reception, this offline capability is critical.

Setting up geofences for your entire project list

If you are just getting started with Projul and have 10 or 15 active jobs, you do not need to sit down and set up all the geofences in one session. As you create or update each project, add the geofence at the same time. It takes 2 minutes, so even 15 projects is only 30 minutes of setup spread across your normal project management workflow.

For new projects going forward, adding the geofence becomes part of your project setup checklist - right alongside entering the address, setting the budget, and assigning the crew. It is one extra step that takes almost no time and pays dividends for the entire duration of the project.

Tips for getting your geofence radius right

The right radius depends on the job. Here are some guidelines based on what contractors using Projul have found works best:

Residential remodels and small additions: 200 to 400 feet. The work area is compact, parking is usually close, and the crew does not need to wander far from the structure.

New residential construction: 300 to 600 feet. Larger lot, more staging area, possibly temporary parking on an adjacent lot or street.

Commercial new construction: 600 to 1,500 feet. Big sites with multiple access points, separate parking areas, and material laydown yards that might be across the road from the main structure.

Multi-building developments: 1,000 to 2,000 feet or more. When the “job site” is an entire subdivision or apartment complex, you need a fence that covers the full footprint your crew might work within.

Service calls and repairs: 150 to 300 feet. Small, contained work areas. A tight fence makes sense here because the entire job might be in a single room.

Start wider than you think you need. You can always tighten the radius if you find the fence is too generous. But a fence that is too tight will flood you with false flags from workers who are legitimately on site but parked just outside the boundary.

Geofencing Privacy Done Right

Privacy is the number one concern crews raise when they hear about GPS time tracking. And honestly, it is a fair concern. Nobody wants their boss tracking their every move, knowing when they stop at the gas station or where they go after work.

Here is the good news: Projul’s geofencing does not do any of that.

What geofencing tracks (and what it does not)

Projul checks your crew’s GPS location at two specific moments: when they clock in and when they clock out. That is it. The app does not continuously track their position throughout the day. It does not record their route to the job site. It does not log where they go on lunch break. It does not follow them home after work.

Think of it like a security badge at an office building. When you badge in at the front door, the system records that you entered the building. When you badge out, it records that you left. But it does not track which floor you are on, how many times you went to the break room, or when you used the restroom. It just knows you arrived and you departed.

Geofencing works the same way. The virtual fence is the “front door” of the job site. Cross it and clock in, and the system records your arrival. Cross it and clock out, and it records your departure. Everything in between is untracked.

This is a critical distinction that separates Projul from apps that use continuous GPS tracking. Some fleet management or employee monitoring tools ping the worker’s location every few minutes all day long, building a complete map of their movements. That feels invasive because it is invasive. Projul does not operate that way.

How to explain it to your crew

The way you introduce geofencing to your team makes a huge difference in how they receive it. Here is a script that works well for contractors who have rolled this out successfully:

“We are switching to an app for time tracking. When you get to the job site, your phone will prompt you to clock in. When you leave, it will prompt you to clock out. The app checks that you are at the right site when you punch in and out - that is all it does. It does not track you during the day, it does not track you on your drive home, and it does not track you on weekends. It is just a smarter version of a punch clock.”

Then address the “why” directly:

“We are doing this because we need accurate labor data for job costing and payroll. Right now we are guessing on a lot of hours, and that means payroll takes longer than it should, job costs are not always right, and sometimes the wrong project gets charged for the wrong hours. This fixes all of that.”

Most crews get on board quickly when they understand two things: the tracking is limited to clock-in and clock-out only, and the purpose is business operations rather than surveillance.

Addressing common crew objections

Even with a good explanation, some workers will have questions or concerns. Here are the most common ones and how to handle them:

“I do not want my boss tracking me all day.” Reassure them that Projul only checks location at clock-in and clock-out. Show them the app if possible. Open it, demonstrate the clock-in process, and point out that there is no live location map or tracking history for individual workers during the workday.

“What if I forget my phone?” They can still clock in - the foreman can enter their time manually, or they can log it when they get their phone. The geofence verification will not be present on a manual entry, but you will see that in the records and can address it as needed.

“What if the GPS is wrong and says I am not at the site when I am?” GPS is accurate within a few feet in most conditions. If a worker is legitimately on site and the GPS puts them just outside the fence, widening the radius by 50 to 100 feet usually fixes it. This is why starting with a wider fence is better than a tight one.

“Is this legal?” Yes. Employers have the legal right to verify that employees are at the work location during work hours. Geofenced time tracking that only checks location at clock-in and clock-out is well within legal norms. Some states have specific notice requirements, so check your local laws, but the practice itself is standard across the construction industry.

“Other companies do not make their crews do this.” Actually, more and more do. GPS time tracking adoption in construction has grown significantly over the past few years. The contractors who resist it are the ones still losing money to time inaccuracy. Position it as your company being professional and running on real data, not as punishment.

Building trust through transparency

The best thing you can do when rolling out geofenced time tracking is be completely transparent about what the system does and does not do. Let your crew see the admin dashboard. Show them what you see when they clock in. Demonstrate that there is no continuous tracking feature, no movement history, no “spy mode.”

When workers can see with their own eyes that the system only records arrival and departure times at the job site boundary, most privacy concerns evaporate. It is the unknown that makes people nervous. When you remove the mystery, you remove the resistance.

Some contractors even let crew members check their own time entries in the app, including the GPS verification status. This gives workers ownership over their own data. They can see that their clock-in was verified, confirm their hours are correct, and flag any issues before payroll runs. That level of transparency turns a potential source of friction into something the crew actually appreciates.

Privacy protections built into the system

Beyond the clock-in/clock-out-only approach, Projul has privacy protections built into how it handles location data:

No location history. The system does not build a map of where each worker has been throughout the day. It stores the GPS coordinates from the clock-in and clock-out events only.

No off-hours tracking. When a worker is not clocked in, the app is not checking or recording their location. Their phone is their phone, and Projul is not monitoring it outside of active time clock events.

Data tied to work events. The GPS data is attached to time entries, not to individual workers as a tracking profile. It exists to verify that a specific clock-in happened at a specific location. That is its only purpose.

These protections are not just good practice - they are what make geofenced time tracking sustainable for your business. A system that feels invasive will create turnover and resentment. A system that respects boundaries while providing accurate labor data will become part of how your crew operates without a second thought.

Using geofencing data for reporting

The location data from geofenced time tracking feeds into your broader reporting picture. You can see which projects are consuming the most labor hours, whether specific sites have attendance issues, and how actual labor compares to estimated labor across your active jobs.

This data is especially valuable during project reviews and post-mortems. When you finish a job, you can look at the actual GPS-verified labor hours against your original estimate. Where did you nail it? Where did you underestimate? That feedback loop is what turns good contractors into great estimators over time.

The key is that all of this reporting is based on verified data. You are not making decisions based on timesheets that might be inflated or charge codes that might be wrong. Every hour in your reports was GPS-confirmed at the correct job site. That is the foundation of reporting you can actually trust.

Stop guessing where your crew is and what it costs

Geofenced time tracking gives you the two things every contractor needs: confidence that labor hours are accurate and real-time visibility into what those hours are costing each project. Over 5,000 contractors use Projul’s GPS time tracking to run tighter crews, catch overruns earlier, and collect on every billable hour. At $4,788/year with no per-user fees, every worker on your team gets access. No per-seat charges that make you think twice about giving the whole crew the app.
