Bookkeeping for Construction Companies
Construction accounting isn't like running the books for a retail shop or a service business. Every job is its own little business, with its own budget, timeline, labor, materials, and profit margin. Generic bookkeeping treats your company as one bucket of income and expenses, and that's exactly how contractors lose track of which jobs actually make money. Roper Accounting Services provides bookkeeping built for the way construction companies really operate.
Why construction bookkeeping is different
If you've ever finished a project that looked profitable on paper but left you wondering where the money went, you've felt the problem. Construction has moving parts that most bookkeeping systems simply aren't set up to handle:
Job costing. Costs have to be tracked per project, not just per category, so you know the true profit on every job.
Work-in-progress (WIP) reporting. Long projects span months and billing periods, and you need to see whether you're overbilled or underbilled at any point.
Progress billing and retainage. You bill in stages, and a portion of each payment is often held back until the job is complete. That money has to be tracked carefully so nothing slips through the cracks.
Fluctuating payroll and subcontractors. Crews change by the job, you juggle W-2 employees and 1099 subcontractors, and public projects may require certified payroll.
Equipment and materials. Big purchases, depreciation, and material costs all affect your numbers and your taxes in ways a standard business never deals with.
When your books don't account for these, you're bidding and making decisions half-blind. When they do, you finally know which jobs, crews, and clients are worth your time.
What we handle for contractors
We tailor our bookkeeping to how your construction business runs, so the reports you get actually help you bid, plan, and grow:
Job costing and profitability tracking so you know the real margin on every project.
Work-in-progress (WIP) schedules that show where each job stands financially.
Progress billing and retainage tracking so you always know what's billed, what's held, and what's owed.
Accounts payable and receivable, including managing subcontractor and vendor payments.
Payroll, including support for certified payroll on prevailing-wage and government jobs.
1099 tracking and filing for your subcontractors.
Clean, current financial statements: profit and loss, balance sheet, and cash flow.
Books that are tax-ready year-round, so filing season is calm instead of chaotic.
The payoff: knowing your numbers job by job
Good construction bookkeeping does more than keep you organized. It tells you which jobs are making money and which are quietly bleeding it, so you can bid smarter and stop repeating unprofitable work. It keeps your cash flow visible so you're never surprised by a slow month. And when you need financing or bonding, or when a bank or surety wants to see WIP schedules and clean financials, you have them ready instead of scrambling.

We help general contractors and subcontractors across the trades, including electrical, plumbing, HVAC, concrete, framing, roofing, remodeling, and specialty contractors. Whether you're an owner-operator running a handful of jobs or a growing company managing multiple crews, we match the level of service to where your business is.
