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.

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.
