Best Small Business Accounting Software for Construction and Contractors

A cloud accounting platform with unlimited users and 1,000+ construction integrations, minus native AIA billing.

Editor's takeXero's biggest edge for construction crews is unlimited users on every plan, letting field staff and project managers log in without per-seat fees competitors like QuickBooks charge. Native job costing stays basic, so Xero leans on a 1,000+ app partner network, including LiveCosts and Buildertrend, to cover AIA billing and retainage it doesn't handle natively. There's also no inbound phone support line, only scheduled callbacks.

Cloud accounting software with a permanently free plan and project-based expense tagging for contractors.

Editor's takeZipBooks offers a permanently free Starter plan with unlimited invoicing and unlimited vendor and customer management, unusual for accounting software. Paid tiers start at just $15 monthly for recurring billing and reporting. It has no Android app, only iPhone, and lacks inventory management, so growing contractors tracking materials may outgrow it.

Construction accounting software with native union payroll, certified wage reporting, and automated AIA billing.

Editor's takeComputerEase automates the parts of construction payroll that trip up generic accounting tools: prevailing wage calculation, unlimited union and local tracking, and certified payroll reports ready for state submission. A 97% renewal rate across 6,000-plus contractors backs up that it holds onto customers once they're trained. That training requirement is real; reviewers consistently compare the interface to decades-old software, and mastering the reporting tools often means paid consulting.

A construction accounting ERP built for job costing, union payroll and prevailing wage compliance.

Editor's takeFoundation targets contractors with complex payroll, automating Davis-Bacon prevailing wage rates, union fringes and multi-state tax rules on a single timecard. It generates certified payroll reports in formats like LCP Tracker. Third-party estimates put monthly costs between $1,200 and $2,500, and reviewers describe the interface as choppy compared to newer cloud tools.

Cloud ERP unifying construction job costing and accounting, with steep implementation costs.

Editor's takeNetSuite unifies construction job costing with core accounting, including native AIA billing support that generic tools lack. That depth comes at real cost, with implementation alone ranging from $20,000 to more than $100,000. Users consistently describe the interface as clunky, and offline mobile functionality stays limited to viewing shifts.

Enterprise construction ERP from Trimble with deep job costing, accounting, and field management.

Editor's takeViewpoint remains a standard for mid-to-large contractors needing rigorous financial controls, backed by parent company Trimble and serving nearly 8,000 construction firms. Its security stack, including SOC 2 Type 2 and ISO 27001, is among the strongest in this category. The Vista interface's dated feel and estimated costs up to $10,000-plus per month are the tradeoffs.

Mobile-first accounting for small contractors with project profitability tracking and job-site invoicing.

Editor's takeFreshBooks fits small contractors and freelancers who need mobile invoicing and a clear read on project profitability, not a full construction ERP. It has more than 24 million users and a 4.5-star GetApp rating. It lacks native AIA (G702/G703) billing needed for commercial jobs, and some users report unstable bank connections that break automated imports.

AICPA-endorsed construction accounting with flat-fee pricing and deep multi-entity consolidation.

Editor's takeSage Intacct is the only accounting software the AICPA names as a preferred provider, and it prices flat by user or module rather than charging a percentage of construction volume like some competitors. Its job costing, AIA billing, and multi-entity consolidation go deeper than generalist ERPs. The mobile app is a real weak point, though, holding a 2.0-star App Store rating over sync failures and plans that won't load, and implementation typically costs 1.0 to 1.5 times the first year's subscription.

Open-source accounting platform with a modular App Store, free when self-hosted.

Editor's takeAkaunting's open-source core is free to self-host, and a modular App Store lets businesses add Stripe, PayPal, or WooCommerce integrations as needed rather than paying for a bloated suite. It has served hundreds of thousands of businesses since 2017. Recent user sentiment has soured though: Trustpilot shows a 1.5 out of 5 score from 55 reviews, largely citing unresponsive support, and double-entry accounting, a fundamental bookkeeping feature, requires the paid Premium plan.
