About Construction Accounting

Construction accounting runs on rules that standard small business bookkeeping was never built to handle. Contracts over the IRS receipts threshold require percentage-of-completion revenue recognition, and even well below that threshold, accurate work-in-progress (WIP) reporting depends on tracking earned revenue against billed revenue by job and cost code — the core of real construction job costing. Certified payroll on prevailing-wage, Davis-Bacon, and government-funded work adds a compliance layer, with weekly
WH-347 reporting
certified payroll reporting and multi-state wage rules that a generic payroll run cannot produce.
Maspartner provides construction accounting and construction bookkeeping services for general contractors, specialty trade subcontractors, remodelers, homebuilders, and land developers. Our clients typically run on QuickBooks Online with construction add-ons, Sage 100 Contractor, Sage 300 CRE, Foundation, or Procore paired with an accounting backend, and we build our construction accounting process around whatever platform they already use rather than forcing a switch.

The Problems We Solve for Contractors.

We generate monthly WIP schedules in construction accounting that compare earned revenue to billed revenue by job, so overbilling gets flagged while there’s still time to act.

We track costs and revenue at the job and cost-code level, giving you accurate construction accounting data to see which projects are profitable and which need attention before closeout.

We track retainage separately on both sides of the ledger, so what’s owed to you and what you owe stays visible at any point.

Our construction accounting services include certified payroll support matched to the correct wage determinations, helping reduce compliance issues before they become audit findings.

We record every change order in the job budget as it happens, so your construction accounting reports reflect the job as actually built, not just as originally scoped.

    FAQs

    Overbilling can make a project appear more profitable than it really is because billed revenue may be higher than earned revenue. A proper construction accounting process uses WIP reporting to compare earned and billed revenue, helping contractors identify overbilling early and avoid unexpected cash flow problems.

    Company-level financial reports can hide losses on individual projects. Job costing tracks labor, materials, subcontractors, and other expenses by project and cost code, while construction accounting gives contractors a clearer view of which jobs are profitable and which need attention.

    Retainage can make cash flow difficult to predict because amounts held by customers and amounts withheld from subcontractors often move on different schedules. Accurate construction accounting tracks retainage separately from regular receivables and payables so expected collections and outstanding obligations remain visible.

    The cost of outsourced construction accounting services depends on factors such as active job volume, company size, reporting needs, certified payroll, and multi-state compliance. A small contractor generally requires less support than a general contractor managing several projects across different states, so pricing is usually based on actual workload.
