Construction Accounting Software: QuickBooks vs Sage vs Foundation | Projul

Construction accounting is not regular accounting. You’re tracking costs across dozens of active jobs, billing by percentage of completion, managing retainage, running certified payroll, and filing AIA documents. Try doing all that in the same software your dentist uses.

Most contractors end up choosing between three options: QuickBooks (because everyone knows it), Sage 100 Contractor (because their accountant recommended it), or Foundation Software (because it was actually built for construction). Each one has real strengths. Each one has real gaps.

We’re going to break down what actually matters and help you figure out the right setup for your company. No fluff, no affiliate links, just an honest comparison from people who’ve been in the field.

Why General Accounting Software Falls Short for Contractors

Here’s the core problem: general accounting tools treat every business the same. A coffee shop and a $10M GC get the same chart of accounts, the same reporting, the same invoicing templates. That doesn’t work in construction.

Job costing is the big one. In construction, you don’t just track income and expenses. You track them per job, per cost code, per phase. You need to know that Job #4872 is 60% complete but you’ve already burned through 75% of the labor budget. General software doesn’t think this way. It thinks in departments at best, not in the job-phase-cost code hierarchy that construction demands.

WIP (Work in Progress) reporting is another gap. If you’re doing work over $10M annually, your bonding company wants WIP reports. They want to see over/under billings, estimated costs to complete, and earned revenue by job. Good luck pulling that from a basic accounting package.

AIA billing matters too. The AIA G702/G703 billing format is standard on commercial projects. It tracks scheduled values, work completed, stored materials, retainage, and change orders in a specific layout. Most general accounting tools have no idea what an AIA pay application even is. So you end up building it in Excel, which means double entry and mistakes.

Then there’s retainage. Holding back 5-10% of each payment until project completion is standard in construction. Your accounting software needs to track what’s been retained, by whom, and when it’s due for release. General tools don’t have a retainage concept at all.

And don’t forget certified payroll, union reporting, prevailing wage tracking, and equipment costing. These aren’t edge cases. They’re Tuesday for a lot of contractors.

The bottom line: general accounting software makes you work around its limitations instead of working with your actual business processes. That’s where construction-specific options come in.

QuickBooks for Contractors: Pros and Cons

Let’s start with the elephant in the room. QuickBooks is everywhere. There’s a good reason for that, and there are some real drawbacks too.

Why Contractors Like QuickBooks

Everyone knows it. Your bookkeeper knows it. Your accountant knows it. Your banker knows it. When tax time comes, nobody’s confused about the file format. That matters more than people think.

QuickBooks Online (QBO) has a massive integration ecosystem. There are hundreds of apps that plug into QBO, including construction project management tools like Projul. That means you can keep QuickBooks for what it’s good at (general ledger, AP/AR, bank reconciliation) and connect it to software that handles the construction-specific stuff.

The price is right for smaller contractors. QBO Plus runs about $80/month. QuickBooks Desktop Pro was around $350-550 as a one-time purchase (though Intuit has been pushing everyone toward subscriptions). For a contractor doing under $2M in revenue, that’s reasonable.

Reporting is decent for basics. Profit and loss by job, expense tracking, invoicing, bank feeds. For simple residential work where you’re not dealing with AIA billing or certified payroll, QuickBooks can handle the job.

Where QuickBooks Falls Short

Job costing is limited. Yes, you can track income and expenses by “customer” in QBO, and you can use classes or projects for some job-level tracking. But it’s not true construction job costing. You can’t easily track estimated vs. actual costs by phase and cost code. You can’t see percent complete vs. percent billed at a glance. You’re going to end up supplementing with spreadsheets.

No WIP reporting out of the box. You’ll need add-ons or a very creative accountant to produce the WIP schedules your surety wants.

No AIA billing. There’s no built-in G702/G703 functionality. Some third-party apps bolt this on, but it’s not native.

No retainage tracking. You can hack it with journal entries, but it’s clunky and error-prone.

The desktop vs. online split is confusing. QuickBooks Desktop had better construction features (especially with Boosted Payroll for certified payroll). But Intuit keeps pushing users to QBO, which has fewer construction capabilities. If you’re on Desktop, you’re fighting the tide.

The Verdict on QuickBooks

QuickBooks works well as your general ledger and financial backbone, especially when paired with construction-specific software for project management and job costing. It’s not great as a standalone construction accounting solution. For residential contractors doing straightforward billing, it might be enough. For commercial work with AIA billing and bonding requirements, you’ll need more.

Sage 100 Contractor: The Enterprise Option

Sage 100 Contractor (formerly Sage Master Builder) is the heavy hitter. It’s been in the construction accounting game for decades, and a lot of larger contractors swear by it.

What Sage Does Well

True construction accounting from the ground up. Job costing, WIP reporting, AIA billing, retainage tracking, change order management, subcontract management. It’s all built in. This isn’t a general accounting tool with construction features bolted on. It was designed for contractors.

Certified payroll and union reporting are solid. If you’re doing prevailing wage work, government contracts, or working with multiple unions, Sage handles the complexity. Payroll in construction is a nightmare with different rates per job, per classification, per jurisdiction. Sage gets it.

Equipment cost tracking. If you own a fleet of excavators and dozers, Sage can track ownership costs, maintenance, utilization, and charge equipment time to jobs. That’s a big deal for heavy civil and sitework contractors.

Multi-state, multi-entity support. Running operations in three states with two LLCs? Sage can handle the consolidation.

Your bonding company and CPA will love the reports. The WIP schedules, job profitability reports, and financial statements come out in formats that sureties and accountants expect.

Where Sage Gets Painful

It’s expensive. You’re looking at $10,000-$30,000+ for implementation, plus annual maintenance fees. The exact pricing depends on modules and number of users, but this is not a budget option. For contractors under $5M in revenue, it’s probably overkill.

The learning curve is steep. Sage is powerful because it’s complex. Training your team takes weeks, not hours. And if your bookkeeper leaves, you’re scrambling to find someone who knows the system.

The interface feels dated. It works, but it looks like it was designed in 2005. The user experience hasn’t kept pace with modern software. Your field crew isn’t going to hop into Sage on their phone between tasks.

Cloud options are limited. Sage has been slow to move to a true cloud model. You can host it on a virtual server, but it’s not the same as native cloud software. Remote access often requires VPN or Citrix setups.

Implementation is a project in itself. Getting Sage set up properly requires a Sage partner or consultant. Your chart of accounts, cost codes, job templates, and workflows all need configuration. If it’s set up wrong, you’ll be fighting the system for years.

The Verdict on Sage 100 Contractor

Sage is the right choice for mid-to-large contractors ($5M-$100M+) doing commercial or government work where AIA billing, certified payroll, and bonding requirements are non-negotiable. If you’re a residential remodeler doing $1.5M a year, Sage is like buying a dump truck to pick up groceries.

Foundation Software: Built for Construction

Foundation Software is the option that doesn’t get as much press but has a loyal following among contractors who’ve been using it for years. It was purpose-built for construction accounting and it shows.

What Foundation Does Well

Job costing is where Foundation shines. Detailed cost code structures, estimated vs. actual tracking, cost-to-complete projections, and job profitability analysis are all core features. If job costing is your top priority, Foundation delivers.

Payroll is a standout feature. Foundation’s payroll module handles certified payroll, prevailing wage, multi-state, multi-trade, and union payroll with less friction than most competitors. A lot of contractors originally chose Foundation specifically for payroll.

AIA billing and retainage are built in. No workarounds needed. Generate G702/G703 pay applications directly from the system, track retainage receivable and payable by job, and manage subcontract retainage.

It’s more affordable than Sage. Foundation typically runs $400-$700/month depending on modules and users. That’s not cheap, but it’s significantly less than a full Sage implementation.

US-based support focused on construction. When you call for help, you’re talking to people who understand construction accounting, not general software support reading from a script.

Where Foundation Struggles

The user interface is aging. Foundation has been modernizing, but parts of the system still feel old-school. If your team is used to slick, modern software, there’s going to be an adjustment period.

Mobile access is limited compared to modern cloud tools. Foundation has made progress with their SMART Screen web-based features, but it’s not as easy as true cloud-native software. Field teams won’t be pulling up detailed accounting reports on their phones.

The ecosystem is smaller. QuickBooks has thousands of integrations. Foundation has fewer third-party connections. That can limit your options if you want to plug in specific tools for other parts of your business.

It’s still primarily an accounting tool. Foundation does accounting and payroll extremely well, but it’s not a project management platform. You’re not going to schedule crews, send estimates, or manage your sales pipeline in Foundation.

Market awareness is lower. Finding a bookkeeper who already knows Foundation is harder than finding one who knows QuickBooks or Sage. Training time is a real factor.

The Verdict on Foundation

Foundation is a strong choice for contractors who prioritize job costing and payroll accuracy and want construction-specific accounting without the price tag and complexity of Sage. It’s well-suited for specialty contractors and GCs in the $3M-$50M range.

How Project Management Software Fills the Gap

Here’s something that most accounting software comparisons miss: your accounting software doesn’t need to do everything.

In fact, trying to run your entire operation from your accounting system is one of the most common mistakes contractors make. Sage and Foundation can handle accounting, payroll, and financial reporting. But scheduling, estimating, CRM, daily logs, photos, and client communication? Those need a different tool.

Thousands of contractors have made the switch. See what they have to say.

That’s where construction project management software comes in. And specifically, that’s where the combination of a PM tool and an accounting tool becomes greater than either one alone.

Take Projul paired with QuickBooks as an example. Projul handles the operational side: estimates, invoicing, scheduling, time tracking, job costing, CRM, and daily logs. QuickBooks handles the financial side: general ledger, bank reconciliation, AP/AR, and tax preparation. The two-way sync between Projul and QuickBooks means data flows automatically. No double entry. No spreadsheets bridging the gap.

This approach gives you several advantages:

Your field team gets software they’ll actually use. Nobody on a jobsite wants to open Sage to clock in. But a mobile app built for field crews? That they’ll use. And when they use it, you get accurate time tracking, daily logs, and progress photos without chasing anyone down.

Your office team gets accurate financials. When time entries, invoices, and job costs sync to QuickBooks automatically, your books stay clean. Your accountant gets what they need at tax time without a two-week scramble.

You avoid paying for features you don’t need. Instead of buying an expensive all-in-one accounting system and only using 40% of its capabilities, you pick the right tool for each job. QuickBooks for accounting ($80/month), Projul for operations (check pricing). Total cost is often less than a mid-tier Sage setup, and you get better functionality in both areas.

Adoption is faster. QuickBooks and Projul are both designed to be learned quickly. You’re not spending $15,000 on implementation consulting. Your team is up and running in days, not months.

This combination is especially powerful for contractors in the $1M-$20M range who need real job costing and professional operations but don’t need the full weight of an enterprise accounting system.

Choosing the Right Setup for Your Company Size

Not every contractor needs the same setup. Here’s a practical guide based on where your company is today.

Under $1M in Revenue (1-5 Employees)

Recommended: QuickBooks Online + Projul

At this size, simplicity wins. You need to track income and expenses, send professional invoices, and keep jobs organized. QBO handles the money side. Projul handles scheduling, estimates, and client communication. You don’t need AIA billing or certified payroll yet. Keep it simple, keep it affordable, and focus on growing.

$1M-$5M in Revenue (5-25 Employees)

Recommended: QuickBooks Online + Projul

Same combination, but now you’re using more of each tool’s features. Projul’s job costing becomes critical because at this size, one or two bad jobs can wreck your year. The QuickBooks integration keeps your financials in sync without hiring a full-time bookkeeper. You might start encountering AIA billing on some commercial jobs. Projul’s invoicing can handle a lot of this, and your accountant can manage the rest in QuickBooks.

$5M-$20M in Revenue (25-100 Employees)

Recommended: QuickBooks Online or Foundation + Projul

This is where you have a real decision to make. If you’re doing mostly residential or light commercial work, QuickBooks + Projul still works well. If you’re doing heavy commercial work with AIA billing on every project, certified payroll, and bonding requirements, Foundation might make sense for the accounting side. Either way, you still want Projul for operations because neither Foundation nor QuickBooks gives your field teams what they need.

$20M+ in Revenue (100+ Employees)

Recommended: Sage 100 Contractor or Foundation + Projul

At this scale, your accounting needs are genuinely complex. Multi-entity, multi-state, union payroll, equipment costing, and sophisticated WIP reporting are part of daily life. Sage or Foundation handles that complexity. Projul keeps your field operations running smoothly and feeds accurate data into your accounting system.

The Common Thread

Notice the pattern? Projul shows up at every level. That’s because the operational side of running a construction company (scheduling, estimating, invoicing, time tracking, job costing, client management) is the same whether you’re doing $500K or $50M. The accounting side scales up in complexity, but the project management side is always needed.

And that’s the real takeaway from this comparison. Don’t try to make your accounting software do everything. Pair the right accounting tool for your size with a project management platform that your whole team will actually use.

Frequently Asked Questions

Can QuickBooks handle construction job costing?

QuickBooks can do basic job-level tracking by assigning income and expenses to customers or projects. But it can’t handle the phase-cost code structure that real construction job costing requires. You won’t get estimated vs. actual comparisons by cost code, percent complete analysis, or cost-to-complete projections without supplementing with spreadsheets or a third-party tool. For true construction job costing, pair QuickBooks with a tool like Projul that was built for job costing.

How much does Sage 100 Contractor cost?

Sage doesn’t publish simple pricing because costs vary based on modules, users, and implementation scope. Expect to pay $10,000-$30,000+ for initial implementation, plus $3,000-$8,000 annually for maintenance and support. Some Sage partners offer hosted/cloud options with monthly billing, but total cost of ownership over three years is typically $25,000-$60,000+. It’s a significant investment that makes the most sense for contractors over $5M in annual revenue.

Is Foundation Software cloud-based?

Foundation has moved toward web access with their SMART Screen features, which let users access certain functions through a browser. However, it’s not fully cloud-native the way modern SaaS tools are. The core system still runs on a server (either on-premise or hosted). For contractors who need true anywhere-access for field teams, pairing Foundation with a cloud-native PM tool like Projul fills that gap.

Do I need construction-specific accounting software, or can I use QuickBooks with add-ons?

It depends on your work. If you’re a residential contractor doing straightforward time-and-materials or fixed-price billing, QuickBooks plus a good project management tool covers you. If you’re doing commercial work with AIA billing, retainage, certified payroll, and bonding requirements, you’ll eventually outgrow what QuickBooks and add-ons can do. The sweet spot for many contractors is QuickBooks for accounting paired with Projul for operations, upgrading to Foundation or Sage on the accounting side only when the complexity demands it.

What’s the best accounting setup for a small contractor just starting out?

Start with QuickBooks Online Plus ($80/month) and Projul. This gives you professional invoicing, payment collection, job costing, scheduling, estimates, and clean books for your accountant. Total monthly cost is a fraction of what you’d spend on Sage or Foundation, and you’ll be operational in a day or two instead of weeks. As you grow and your accounting needs get more complex, you can upgrade the accounting side without changing your project management workflow. Don’t over-engineer your tech stack before you need to.
