Best Accounting Software for Contractors in 2026: Job Costing, Retainage and Certified Payroll

The best accounting software for contractors is usually one of two shapes: a construction layer on top of a QuickBooks ledger, or a construction accounting system that is the ledger. Knowify at $99 a month billed yearly and JobTread at $199 a month are the layer, and they carry the billing work general accounting software does not do, including AIA pay applications and Davis-Bacon certified payroll reports in Knowify’s case. Sage 100 Contractor and Foundation Software are the second shape, complete construction ledgers with certified payroll inside them, and neither publishes a price. QuickBooks Desktop Enterprise with the Contractor edition keeps everything in one Windows system from $2,210 a year, and documents job costing but not progress billing on AIA forms, retainage or certified payroll.

The short version: Knowify if your books already live in QuickBooks Online and you bill progress, JobTread if you want unlimited free portals for subs and clients, Sage 100 Contractor or Foundation Software if you run prevailing wage payroll and want one system, Acumatica Construction Edition if you need a full ERP, and QuickBooks Desktop Enterprise only if job costing is the whole requirement.

What makes construction accounting different

Four things separate construction books from ordinary small-business books. Three of them have a primary source behind them. The fourth, retainage, has none, which changes how you should compare products on it.

Job costing and progress billing

Every cost gets coded to a job and a cost code and compared against the estimate, and bills go out as a percentage of a schedule of values rather than as an invoice for work completed. The industry’s pay application forms are AIA G702 and G703; Knowify lists support for both by name on its pricing page, which is the kind of specific claim worth checking on any shortlist.

Retainage is a contract term, not an accounting standard

Retainage, the percentage of each payment a customer withholds until the job is finished, has no federal rule behind it. It is a matter of the contract you signed and of state law, both of which vary, so the question to ask a vendor is mechanical: can the system hold retainage receivable separately from ordinary accounts receivable and release it on schedule? Among the products below, Acumatica states on its construction page that its change orders handle “unit rate changes, custom retainage, and cost-only change requests.” Most of the others do not put retainage in writing on a public page.

Percentage of completion, and the small contractor exception

IRC section 460 requires long-term contracts to be reported under the percentage-of-completion method. Section 460(e)(1)(B) exempts a construction contract where the taxpayer estimates at the time the contract is entered into that it will be completed within the two-year period beginning on the commencement date, and meets the gross receipts test of section 448(c) for the year the contract is entered into, per the text of section 460 published by Cornell’s Legal Information Institute. Residential construction contracts that are not home construction contracts get a three-year window instead of two.

The section 448(c) figure is inflation-adjusted each year. It is $31,000,000 for tax years beginning in 2025, per Rev. Proc. 2024-40 section 2.31, and $32,000,000 for tax years beginning in 2026, per Rev. Proc. 2025-32 section 4.30. Both conditions have to be met, so the exception turns on contract length as much as on size. Whether your contracts qualify is a question for your CPA, not for a software vendor.

Certified payroll: the weekly submission is mandatory, the form is not

Contractors and subcontractors on Davis-Bacon and Related Acts work must pay laborers and mechanics no less than the locally prevailing wages and fringe benefits for corresponding work in the area, per the Department of Labor. The reporting rule is stated precisely by the DOL and is widely misquoted: “While use of Form WH-347 itself is optional, covered contractors and subcontractors performing work on Federal or federally assisted construction contracts are required by the DBRA regulations and the contract clauses to submit payroll information on a weekly basis.” The Copeland Act requires a statement of the wages paid each employee during the prior week, and 29 CFR 5.5(a)(3)(ii) requires the weekly certified payrolls to go to the contracting agency or its designee.

So the software question is not whether a product prints Form WH-347. It is whether the system can produce weekly payroll information carrying each worker’s classification, hours by class, rates and fringes, for every federally funded job.

US list prices as of September 2026. “Quote only” means the vendor publishes no price at all.

QuickBooks Desktop Enterprise, Contractor edition

Intuit sells seven industry editions of Desktop Enterprise: Construction and Contractors, Manufacturing, Wholesale and Distribution, Nonprofit, Professional Services, Retail, and Accounting Professional. Each includes the same key features as standard Enterprise plus reports, charts of accounts and menu items tailored to the business type, and Intuit highlights job costing for the construction edition. There is no industry surcharge, so the price is the ordinary Enterprise price: Gold $2,210 a year, Platinum $2,717 and Diamond $5,363, with Silver quoted at $1,873 a year by NerdWallet since Intuit names Silver in its terms without printing a price. Gold and Platinum cover 1 to 30 users and Diamond up to 40, cloud hosting costs extra, and Enterprise is Windows only. As of September 2026 Intuit’s Enterprise pricing page is also running a promotion, showing $19 a month across Gold, Platinum and Diamond with no annual total; treat that as an introductory rate and budget from the annual list prices.

What this buys is narrower than the contractor branding suggests. Intuit documents job costing for the Contractor edition. It does not document AIA pay applications, retainage tracking or certified payroll as Enterprise features, which is precisely the gap Knowify, Foundation and Sage 100 Contractor sell into. Note also that Enterprise is the only Desktop product Intuit still sells to new US buyers: Pro Plus, Premier Plus and Mac Plus closed to new subscriptions after September 30, 2024, which our QuickBooks Online versus Desktop guide covers in full.

Skip it if you do federal work, need retainage held separately, or want anything on a Mac.

Knowify

Knowify is job costing, progress billing and project management built around a QuickBooks sync, and it is the most specific of these products about construction billing. Its pricing page names AIA pay applications on G702 and G703 forms, real-time work in progress calculation, change-order tracking with notifications, automatic expense allocation to projects, scheduling, time tracking and a field app. Its prevailing wage page states that automated tools create certified payroll reports for public works and government-funded jobs, with labor details auto-populated for every Davis-Bacon job including each employee’s name, role, pay type, regular and overtime hours and fringe benefits.

Plans are Core at $99 a month billed yearly or $149 billed monthly, with one user included, and Advanced at $329 billed yearly or $399 monthly with ten users. Extra users are $29 a month on either plan, and Enterprise is custom. A five-person remodeler on Core billed yearly pays $99 plus four extra users at $29, which is $215 a month or $2,580 a year, and still needs the ledger underneath: QuickBooks Online Plus at $140 a month is another $1,680 a year, for $4,260 all in.

The buying constraint is which QuickBooks you run. Knowify integrates with QuickBooks Online, QuickBooks Online Payroll and QuickBooks Payments on every plan, but QuickBooks Desktop support starts at Advanced, so a Desktop shop is looking at $329 a month rather than $99. Skip Knowify if you want one system rather than two.

JobTread

JobTread is construction management for builders and remodelers, covering jobs, documents, schedules, time tracking and reporting, and it syncs to QuickBooks Online rather than keeping its own ledger. The price is $199 a month for the Standard plan, which includes one internal user, with no contract, no setup fees and a 30-day money-back guarantee on monthly subscriptions. Additional internal users are tiered: $20 a month each for users 2 through 10, $15 for 11 through 20, $10 for 21 through 30 and $5 from 31 up, with lower rates on annual billing, which JobTread advertises as saving 20 percent.

The feature that separates it is the portals. Vendor, customer and subcontractor portal users are unlimited and free, as are implementation, training and support, which matters for a builder coordinating twenty subs who should not each cost a seat. Named integrations include QuickBooks Online, Home Depot, PoolCorp, SRS Distribution, Gusto, Zapier and NiceJob.

That same five-person remodeler pays $199 plus four users at $20, which is $279 a month or $3,348 a year on monthly billing, plus the QuickBooks Online subscription underneath. Skip it if your billing runs on AIA forms or you need certified payroll, neither of which JobTread publishes.

Buildertrend

Buildertrend is project management with financial tools attached, aimed at residential builders and remodelers, and it targets companies running five or more projects a year with six to eight figures of annual revenue. Every plan includes unlimited users and unlimited projects, which is unusual and is the main reason to look at it.

As of September 2026 Buildertrend no longer publishes plan prices. Its pricing page asks a few questions about the business and then books a call, so any monthly figure you see quoted in a round-up is a price Buildertrend does not currently publish. A promotion is running alongside that: 10 percent off when you pay annually up front, described as limited time. Buildertrend does not name its accounting integrations on the pricing page, so confirm the QuickBooks or Xero path before you sign.

One piece of housekeeping for anyone comparing the two: CoConstruct is not an alternative to Buildertrend any more. CoConstruct’s site now describes its transition to Buildertrend as entering its final phase and exists to move customers across, so it is not a product for a new buyer.

Sage 100 Contractor

Sage 100 Contractor is a complete construction accounting and operations system for small to midsize contractors, including those moving up from Sage 50. Sage’s own description of the compliance work is the reason it belongs on this list: “Whether it’s certified payroll, AIA billings or lien waivers, you can now manage them all with one powerful tool.” The named capabilities run to job costing, project management, integrated estimating, service management, purchase orders and subcontracts, with Sage Construction Management and Sage Estimating sold as add-ons.

Sage publishes no price and no free trial for it; the page routes to its construction specialists. Budget for a quote, an implementation and a year of learning a system that is deeper than anything on the QuickBooks side of this list.

Pick it if certified payroll and AIA billing are weekly work and you want one ledger. Skip it if you have five employees and two jobs running, where the layer products cost a fraction of this.

Foundation Software

Foundation is construction accounting that puts job costing, payroll, invoicing, vendor payments and financial reporting in one system, and the payroll side is what distinguishes it: the vendor names certified payroll processing with prevailing wage compliance, and sells Payroll4Construction as a construction payroll product handling multiple states, rates and trades on a single timecard. The wider product line includes WorkMax for mobile time and labor, SafetyHQ, and the McCormick and The EDGE estimating products. Foundation describes its customers as contractors from small to large, commercial and residential, including those handling union and prevailing wage jobs, and claims to be “America’s #1 Construction Accounting Software” with more than 43,000 construction professionals, which are the company’s own claims rather than an independent finding.

No prices are published on the home page or the products page, and there is a sales phone number rather than a checkout. Pick it if union fringes, multiple trades and prevailing wage jobs are the hard part of your week. Skip it if payroll is five people on one rate.

Acumatica Construction Edition

Acumatica Construction Edition is a full cloud ERP for general contractors, specialty contractors and developers, covering job cost accounting, project management, change-order management and multi-entity and multi-currency financials. Its construction page states that change orders handle unit rate changes, custom retainage and cost-only change requests, which is one of the few public, vendor-written retainage claims among these products. AIA billing and certified payroll are not named on that page, so ask about both.

Acumatica publishes no price list and sells only through partners, so quotes come from a reseller. Two published facts are worth carrying into that conversation. Its APEX program advertises a customized package with implementation and support included, starting under $1,500 a month, which is a bundled starting price rather than a software list price. And its Licensing Guide states that renewal prices for its subscriptions will not increase by more than 10 percent a year, subject to conditions: you cannot reduce edition, tier or user count, services and Marketplace products are excluded, discounts do not carry into the renewal base, and growing past a transaction tier still costs more because the cap protects the rate rather than the tier. Our Acumatica pricing page works through the two licensing methods and what buyers report paying.

Skip it unless you have outgrown construction-only software, since an ERP implementation is a project in its own right.

Sage 300 Construction and Real Estate

Sage 300 CRE is the larger sibling of Sage 100 Contractor, aimed at contractors, developers and property managers who need financial management and project or property oversight in one place. Sage names Sage Field Operations for assignments, work orders and equipment, Construction Management for bidding and delivery, Service Management for dispatch and customer portals, and Property Management for leases and tenant communications, along with document management through Sage Paperless Construction and more than 1,400 prebuilt report formats. Pricing is quote only.

The reason to choose it over Sage 100 Contractor is property: if you build and then hold and lease what you built, this is the product in the Sage line that covers both. If you never touch a lease, it is more system than you need.

Procore financial management

Procore’s financial management module covers budget tracking and cost forecasting, change management, invoice management and subcontractor payments. It is explicitly not a general ledger. Procore integrates with the accounting system instead, and the ERPs it names are a useful shortlist in themselves: Sage 100 Contractor, Sage 300 CRE, QuickBooks, Viewpoint Spectrum, Viewpoint Vista, CMiC, Xero and Yardi.

Procore publishes no prices and no pricing model on that page, only a demo request. Treat it as project management your project teams may already be using, with financial visibility attached, and keep the ledger question separate.

The general-purpose option

QuickBooks Online covers a contractor’s books adequately up to a point. Inventory, project profitability and job costing all start at the Plus plan, $140 a month as of September 2026, and Advanced at $340 adds unlimited classes and locations for businesses tracking many jobs or divisions. What it does not do is progress billing on AIA forms, retainage or certified payroll, which is why Knowify and JobTread exist and why both sell themselves on the QuickBooks sync rather than against it.

Sage 50 is the other general-purpose answer, and it suits a small Windows shop. List prices are $69.42, $123.25 and $211.92 a month for Desktop Pro, Premium and Quantum, and $128.67, $182.50 and $271.17 for the equivalent Cloud plans. Job management is in Pro, advanced job costing arrives at Premium and project management at Quantum. The costs to weigh: Windows only, no US mobile app, no free trial at all, and a minimum one-year commitment where access ends when the subscription does. Our QuickBooks versus Sage comparison sets the two side by side.

How to choose

• You bill progress against a schedule of values: Knowify, whose AIA G702 and G703 support is published, or a construction ledger such as Sage 100 Contractor.
• You run Davis-Bacon or union payroll: Foundation Software or Sage 100 Contractor for one system, Knowify if the ledger stays in QuickBooks Online.
• Retainage currently lives in a spreadsheet: ask every vendor to show it in a demo, and note that Acumatica is the one here that states custom retainage on change orders in writing.
• Your contracts run under two years and receipts are well under the section 448(c) threshold: the tax method question is settled with your CPA, and the software choice comes down to job costing and billing.
• Job costing is the entire requirement: QuickBooks Desktop Enterprise Contractor edition, or QuickBooks Online Plus if you would rather be in the cloud.
• You have outgrown construction-only software: Acumatica Construction Edition, with Sage 300 CRE if you also hold property.

Our accounting and ERP software guide sorts these by business size, and the head-to-head comparisons go deeper on the QuickBooks pairings.

When to bring in an accountant

The two decisions on this page that software cannot make for you are tax method and payroll compliance. Whether a given contract qualifies for the section 460(e) exception depends on its estimated duration and on your gross receipts under section 448(c), and getting it wrong changes when income is recognized across every open job. Certified payroll adds weekly filing obligations with classifications and fringes that have to match the wage determination in your contract. A CPA who works with contractors will set the method, the cost codes and the payroll classes once, so the software has something correct to report against. Our directory lists firms by location, and if you are large enough to need someone owning cash flow and work in progress reporting month to month, fractional CFO help is the cheaper version of that hire.
