Construction accounting is not standard accounting. A residential developer, a commercial general contractor, and a specialty subcontractor all run their finances through a framework built around individual projects — not products or service hours. Every dollar earned, every cost incurred, and every cash flow forecast ties back to a specific job. The software that handles this well is a narrow category, and the wrong choice creates months of cleanup work.
What Construction Companies Need from Accounting Software
The requirements that separate construction accounting from general bookkeeping are specific and non-negotiable. Construction firms that use a general-purpose accounting tool report spending 30–50% more staff time on billing reconciliation than firms using a purpose-built platform.
Five Core Requirements
Job costing. Every expense — labor, materials, subcontractors, equipment, overhead allocation — must be coded to a cost code within a specific job. Without granular job costing, you cannot know which projects are profitable, which are overrunning, or where estimates are consistently off. This is the single most important feature.
AIA billing. Most commercial construction contracts use AIA G702/G703 progress billing — the schedule of values format that breaks a contract into line items and bills a percentage complete each month. Your accounting software should generate these forms natively, not require you to export to Excel and rebuild them manually.
Certified payroll and Davis-Bacon compliance. Any contractor working on federally funded or state-funded public works projects must produce certified payroll reports proving that workers received prevailing wages. This requirement (Davis-Bacon Act) is time-consuming to handle manually and carries significant penalty risk. Purpose-built construction payroll modules handle it automatically.
WIP (Work-in-Progress) reporting. Lenders, sureties, and your own management need a monthly WIP schedule that shows overbillings and underbillings across every active job. This is a construction-specific financial statement that general accounting software does not produce without significant customization.
Lien waiver management. Subcontractor and supplier lien waivers must be tracked against each payment to protect the owner’s property. Tracking this in a spreadsheet outside the accounting system is a common source of dispute and legal exposure.
Best Accounting Solutions for Construction Companies
Five platforms cover the majority of the construction accounting market: Sage 100 Contractor, QuickBooks Online, Foundation Software, Xero, and Jonas Construction. Each targets a different contractor size and billing complexity.

Sage 100 Contractor (formerly Sage Master Builder) is one of the most widely deployed construction accounting platforms for mid-market general contractors. It covers job costing, AIA billing, certified payroll, equipment tracking, and WIP reporting in a single system. The interface is not modern, but the depth is real — estimators, project managers, and accountants all work from the same data set. Implementation requires professional setup, and the annual software cost reflects that.
QuickBooks Online is the entry point for small contractors who already know the product or want to minimize software spend. The Projects feature provides job-level profit-and-loss tracking, and it integrates with popular construction project management tools like Procore and Buildertrend. The limitations become apparent as project count and billing complexity grow: no native AIA billing, no certified payroll, no WIP schedule. For a contractor running fewer than a dozen simple jobs at a time, it is a pragmatic starting point.
Mid-Market and Enterprise Options
Foundation Software is built by contractors for contractors and is particularly strong on certified payroll and job cost reporting. Its payroll module handles multi-state work, union fringes, and Davis-Bacon compliance with less manual intervention than most competitors. The WIP report is a first-class feature, not an afterthought. Foundation is a serious platform with a corresponding price and implementation commitment — the right fit for contractors in the $5M–$100M revenue range.
Xero is a general accounting platform that construction firms use when their billing is simple (time-and-materials, fixed-fee) and their team is already comfortable with Xero. It lacks native construction features but handles bank reconciliation, payroll (via integrations), and basic job tracking. Best suited for specialty subcontractors with a small project portfolio and no certified payroll requirements.
Jonas Construction targets larger general contractors and specialty contractors who need ERP-level integration across accounting, project management, service management, and equipment. It is more powerful than Sage 100 Contractor but also more complex to implement and maintain. Typical customers are contractors in the $20M+ revenue range with dedicated IT resources.
How to Choose Accounting Software for a Construction Company
Match complexity to features. A painting subcontractor with five active jobs, simple time-and-materials billing, and no public works projects has different needs than a commercial GC running 30 concurrent projects with AIA billing and certified payroll. Buying Foundation or Jonas for the former is overkill; using QuickBooks Online for the latter creates serious operational gaps.
Prioritize certified payroll if you do public works. If any of your revenue comes from federal or state contracts subject to prevailing wage requirements, certified payroll compliance is non-negotiable. Foundation and Sage 100 Contractor handle this natively. QuickBooks Online does not — you would need a third-party add-on or a manual process.
Consider your estimating and project management stack. Construction accounting software is most valuable when it shares data with your estimating and project management tools. Check what integrations are available before choosing a platform. Sage 100 Contractor and Jonas have tighter native integration; Foundation and QuickBooks Online have extensive third-party connector ecosystems.
Get a demo with real project data. Construction accounting software demos are only meaningful if you walk through a scenario that reflects your actual work: a progress billing draw, a certified payroll run, or a WIP schedule for your current backlog. Generic demos obscure the rough edges that matter in daily use.
For small contractors starting out, QuickBooks Online is the practical default. For contractors with certified payroll requirements or complex job costing, Foundation Software or Sage 100 Contractor are the serious options. Large GCs with cross-functional integration needs should evaluate Jonas Construction.
