Best accounting software for general contractors, picked for retainage and WIP

Seven platforms take on the path from estimate to month-end report in 2026, and each one suits a different type of general contractor (GC).

Pick by company size and where your estimates live:

  • Premier Construction Software: midsize GCs that want accounting and project management in one cloud system. Capterra lists it from $125 for each user, each month.

  • Sage 100 Contractor: smaller GCs that want estimating and payroll in one installed program.

  • FOUNDATION: midsize GCs that run union payroll in-house.

  • Acumatica Construction Edition: growing GCs that want unlimited users. Acumatica says pricing starts under $1,500 a month.

  • CMiC: large GCs with their own ERP staff.

  • Trimble Viewpoint Vista: large general, civil, and heavy highway contractors.

  • Buildertrend: residential builders and small GCs. QuickBooks or Xero keeps the books.

A contractor's job does not start in the ledger. It starts with an estimate, turns into a budget, gets billed against a schedule of values, and only then lands in the books.

Most of these platforms are strong on one or two of those steps.

What general contractor accounting software has to do that bookkeeping tools do not

A general ledger tool like QuickBooks tracks money by account. Construction accounting tracks money by job. That one difference is why many contractors outgrow a generic tool somewhere around $5 million in revenue.

Job costing tags every labor hour, material invoice, equipment charge, and subcontractor bill to a job, and usually to a phase and cost code inside it. Without it, you learn a job lost money only after it closes.

Most commercial GCs get paid through progress billing on AIA G702 and G703 forms. The G703 lists the schedule of values line by line. The owner and architect sign the G702 summary page.

Software that builds both forms from job cost data saves hours of retyping every month.

A GC sits on both sides of retainage: the owner holds it back on you, and you hold it back on your subcontractors.

Your software needs to track retainage receivable and retainage payable separately, by job.

Work in progress (WIP) reports show, job by job, what you billed against what you earned. Bonding companies and banks read the WIP schedule closely.

As one CFMA article on WIP puts it: "Arguably, it's the most important part of your financial statements."

Public work covered by the Davis-Bacon Act needs weekly certified payroll reports.

The Department of Labor says the act applies to each federal contract "in excess of $2,000" for building or repairing public works.

A GC that bids public work needs the system to handle prevailing wage rates, fringe benefits, and Form WH-347, or an equivalent report.

How these construction accounting software platforms are compared

Each platform gets the same four checks: how an estimate becomes a job budget, how progress billing and retainage work, how the WIP schedule is produced, and how payroll is handled.

The 7 platforms

1. Premier Construction Software

Premier Construction Software is a cloud construction ERP built around accounting, for midsize GCs and owners with roughly $5M to $500M+ in revenue.

It covers AP, AR, progress billing, WIP and job costing, plus project management.

Each job gets up to five levels of costing, and the WIP report opens in seconds instead of being rebuilt in Excel.

Billing covers AIA, cost plus, lender draws, and T&M, with retainage tracked on both sides.

  • Estimating to accounting: you build the estimate in your own estimating tool and bring it in as the job budget.

  • Rating: 4.7 out of 5 on both Capterra and G2.

  • Pricing: charged for each user, each month. Capterra lists plans from $125 at higher volumes. Premier offers a 30-day money-back guarantee.

  • Where it falls short: no built-in estimating, and paychecks and tax filing go through an integrated payroll provider.

2. FOUNDATION

FOUNDATION is construction accounting software from a US company that has focused on contractors for decades. It suits midsize GCs that run union and prevailing wage payroll in-house.

Its strength is payroll: timecards for many states, unions and trades, Davis-Bacon and union fringes, and certified payroll reports.

Job costing, AP, AR, and AIA billing sit on top of that payroll engine.

  • Estimating to accounting: estimating comes from takeoff and estimating partners. FOUNDATION has no estimator of its own.

  • Rating: 4.3 out of 5 on Capterra (416 reviews).

  • Pricing: custom quote. FOUNDATION does not publish prices.

  • Where it falls short: the interface is dated, and project management is thin, so many GCs add a separate tool.

3. Sage 100 Contractor

Sage 100 Contractor (formerly Master Builder) is installed accounting software for GCs under roughly $10M that can run on their own computers or server.

A won estimate becomes the job budget without retyping, and payroll, workers' compensation, and weekly certified payroll are included.

  • Estimating to accounting: built in. Estimate, budget, job cost, and payroll share one database.

  • Rating: 3.8 out of 5 on G2 (24 reviews, a small sample).

  • Pricing: custom quote, sold per license with no fee for each user.

  • Where it falls short: it runs on your own servers, so remote access needs your own hosting or a hosting provider.

    Reviewers call the interface dated and the learning curve long.

4. Acumatica Construction Edition

Acumatica Construction Edition is a cloud ERP for growing GCs that add office and field users fast. It has job costing, AIA billing, WIP automation, and payroll that supports certified wages and many unions.

Acumatica says you only pay for the functionality you need and the data you use, with unlimited users.

  • Estimating to accounting: the CRM carries a job "from estimate to lead to quote to awarded project," but detailed takeoff and estimating usually happen in a separate tool.

  • Rating: 4.4 out of 5 on G2 (about 2,050 reviews across all Acumatica editions).

  • Pricing: Acumatica's Construction Edition page says pricing starts under $1,500 a month, with unlimited users.

  • Where it falls short: it is a general ERP with a construction edition added on, so setup usually goes through a reseller partner, and that partner shapes the result as much as the software.

5. CMiC

CMiC is an enterprise construction ERP and the heaviest general contractor accounting software on this list, built for large GCs with hundreds to thousands of employees.

Certified and union payroll rules are built in. Job costing, project controls, and forecasting run on the same database as the general ledger.

  • Estimating to accounting: estimating is not a core module. Most CMiC customers bring estimates in from a dedicated estimating product.

  • Rating: 4.0 out of 5 on G2 (118 reviews).

  • Pricing: role-based licensing quoted by CMiC. ERP Research lists typical cost at $50,000 to $150,000 or more a year, with implementation taking 6 to 18 months.

  • Where it falls short: implementation is long, the learning curve is steep, and collaboration with owners and subcontractors is weaker than in project-first tools.

6. Trimble Viewpoint Vista

Vista is longstanding enterprise construction accounting software, now owned by Trimble, for large general, civil, and heavy highway contractors. It handles job cost accounting, change orders, and cost-to-complete reporting.

Its payroll module for many states, unions, and certified payroll is a main reason contractors pick it.

Trimble hosts Vista on Azure and is moving customers toward its Trimble Construction One cloud bundle.

  • Estimating to accounting: estimating sits outside Vista and usually comes from a separate product that feeds the job budget.

  • Rating: 4.0 out of 5 on G2 (137 reviews).

  • Pricing: quote only. Trimble does not publish pricing.

  • Where it falls short: reporting is strong but hard to customize without a specialist, and support responsiveness is the most common complaint. It is too much software, and too much money, for small contractors.

7. Buildertrend

Buildertrend is cloud construction management software for residential builders, remodelers, and small GCs that sell jobs with proposals.

It has estimates, takeoff, scheduling, and a client portal, and it is the friendliest tool on this list for the sales end of a job. It does not try to be a general ledger. It connects to QuickBooks or Xero, which hold the books.

  • Estimating to accounting: estimating is built in and strong. Accounting is handed to QuickBooks or Xero, so WIP and certified payroll depend on those tools.

  • Rating: 4.5 out of 5 on Capterra (2,489 reviews).

  • Pricing: quoted by annual construction volume. Its last published plans (late 2024) ran from $449 to $989 a month, paid for the whole year.

  • Where it falls short: it does not replace accounting software for a GC running commercial work with AIA billing and WIP.

Cloud vs on-premise accounting software for contractors

Cloud lets PMs and supers enter time, approve invoices, and check budgets from the job site, with no server or backups to maintain. You pay a subscription for as long as you use it.

The annual vs. monthly calculator shows what paying for the whole year saves.

On-premise gives you control of the data and the upgrade timing, but remote access needs extra hosting or a VPN, and upgrades are your job.

How to choose general contractor accounting software by company size

Start with the gap you feel every month. If someone rebuilds the WIP schedule in Excel every month-end, you need built-in WIP.

If billing day turns into retyping the schedule of values into AIA forms, you need G702 and G703 built from job cost data.

  • Under about $5M in revenue: QuickBooks plus a front end like Buildertrend is usually enough, or Sage 100 Contractor if you want estimating and payroll together. Move when you track retainage and over- and under-billing in side spreadsheets.

  • From $5M to roughly $100M: a cloud platform pays off here. Pick FOUNDATION for in-house union payroll, Acumatica for fast-growing user counts, and Premier Construction Software for accounting and project management in one system.

  • Above $100M, or with many entities, unions, and states: CMiC and Vista are built for that complexity, if you have the staff to run them.

Bonding is another trigger. The SBA surety bond program guarantees bonds for small contractors on contracts "up to $9 million for non-federal contracts and up to $14 million for federal contracts."

Before you commit, run your user count, price for each user, and hours saved through the SaaS ROI calculator.

FAQ

Can QuickBooks handle construction job costing?

Only in part. QuickBooks can tag costs to a project, but it has no built-in WIP schedule, no AIA G702/G703 billing, and no certified payroll.

What is the difference between construction accounting software and project management software?

Construction accounting software owns the money: the general ledger, AP, AR, payroll, billing, and WIP. Project management software owns the work: RFIs, submittals, daily logs, and drawings.

For the project side, see the list of best project management software for 2026.

Do general contractors need certified payroll?

Only on prevailing wage projects, such as federally funded jobs covered by Davis-Bacon or state public works. If you bid that work even occasionally, choose a system that produces the weekly report.

Which accounting software for general contractors includes estimating?

Sage 100 Contractor and Buildertrend have built-in estimating. The others on this list expect you to bring estimates in from a dedicated estimating tool.

Where to start

No single tool is best at every step from estimate to WIP.

For midsize general contractors and owners who want accounting software for general contractors with real-time job costing, AIA progress billing, retainage tracking, and a WIP report in seconds, all in one cloud system with project management on the same data, Premier Construction Software offers plans listed from $125 per user, each month, with a 30-day money-back guarantee.
