Construction & Contractors
Construction & contractor accounting
Job costing that shows which jobs actually made money. General contractors, subcontractors, and the trades — we run real job-cost accounting that ties every dollar of labor, materials, and equipment back to the job, so you know your margin while the work is happening, not months after it closes.
The challenge
Where it gets hard
These are the places generic bookkeeping breaks down for construction & contractors — and exactly what we account for.
- No true job costing — you can't tell which jobs make or lose money
- Change orders, progress billing, and retainage tracked in spreadsheets
- Work-in-progress (WIP) and over- / under-billing nobody can explain
- Certified payroll, prevailing wage, and 1099 subcontractors to keep straight
Our approach

FAQ
Construction & Contractors accounting, answered
The questions we hear most about construction & contractors books — answered straight.
Job costing ties every dollar of labor, materials, equipment, and subcontractors to the specific job that incurred it, so each project has its own profit-and-loss. It's how you see which jobs actually made money while you can still act on it — a single company-wide P&L hides the losers behind the winners.
Yes. We produce work-in-progress (WIP) schedules with percentage-of-completion and over- / under-billing — the report bonding companies, sureties, and lenders ask for first.
Yes. Certified payroll, prevailing-wage work, retainage receivable and payable, change orders, and 1099 subcontractors are all part of how we keep contractor books bonding- and lender-ready.
