Construction bookkeeping that finally tells you which jobs are making money — built for contractors juggling multiple active projects, with reliable job costing, clean monthly closes, and WIP-ready financials your lenders and CPA can trust.
This service covers the core construction accounting and bookkeeping required to keep your books accurate and job costing reliable on an ongoing basis.
We handle transaction posting, reconciliations, general ledger maintenance, and disciplined month end close. All costs are recorded at the job and cost code level so labor, materials, equipment, and subcontractor expenses land on the correct jobs. This creates a clean foundation for job costing, WIP, retainage, and consistent financial reporting.
We also perform accounting cleanups and restructures when books are messy or historically misaligned, either as part of onboarding or as a separate scope.
Our role is to manage the accounting system and maintain accurate financial data, while your team continues to oversee day to day operations and approvals. This shared structure helps ensure the numbers stay accurate and aligned with how work is actually performed.
Most construction accounting issues come down to structure and consistency. When systems are not built around jobs, the numbers stop reflecting what is actually happening in the field. We regularly step in to fix problems such as:
Once construction accounting is structured correctly and maintained consistently, the difference is clear. This is what clients experience after we take over construction accounting and bookkeeping:

Testimonials from construction businesses we support with ongoing accounting and bookkeeping.
"FinTruction is the only bookkeeping team we've found that truly understands construction accounting and WIP reporting. They took six months of messy data, cleaned our financials, and showed us exactly where we were profitable and where we were leaking money. Their attention to detail and responsiveness is unmatched. They are a true partner."
- Job costs finally lined up
- Cash flow stopped jumping around
- WIP and retainage handled correctly
- Problems caught before they turned into losses
"We were running multiple jobs, and the numbers never lined up. FinTruction went back, cleaned everything, fixed our job costing, and set up WIP properly. Now I can open the reports and actually understand where each job stands."
"What stood out was that they already understood construction. Job costing, retainage, payroll, nothing needed explaining. The books are clean every month, and the reports are consistent, which makes planning a lot easier."
"Before this, we were mostly reacting. Now we know what's coming in, what's still owed, and which jobs are doing well. Cash flow is clearer, and there's a lot less stress around the numbers."
This service is built for contractors who run on jobs. Here is exactly who it fits — and who it does not.
Pricing is structured around monthly service packages based on the size and complexity of your construction operations.
Costs are driven by factors such as transaction volume, number of active jobs, number of entities, and payroll complexity. Each package includes ongoing construction accounting, job costing support, monthly close, and standard financial reporting.
One-time onboarding or cleanup fees may apply when books require restructuring before ongoing services begin.
Common questions from construction businesses considering ongoing accounting and bookkeeping support.
Yes. Our bookkeeping and accounting services are built exclusively for construction businesses. Everything we do is designed around job costing, cost codes, WIP retainage, and multi-job operations. We do not provide generic bookkeeping for non-construction industries.
We structure your accounting system so every transaction is tied to a specific job and cost code. Labor, materials, subcontractors, equipment, overhead allocations, and change orders are tracked separately for each project. We maintain real-time job cost reports and compare actual costs to budgets throughout the project lifecycle. This ensures profitability is monitored continuously, not just at completion.
Yes. We first review your current chart of accounts and cost code structure to determine whether it accurately reflects how your projects operate. If the structure works, we optimize and standardize it. If improvements are needed, we redesign it carefully without disrupting active jobs. The goal is clarity and job-level visibility, not unnecessary complexity.
Yes. We prepare and maintain accurate Work in Progress schedules for contractors operating under percentage of completion accounting. We calculate overbillings, underbillings, earned revenue, and cost to complete so financial statements reflect true project performance. This ensures accurate reporting for lenders, bonding companies, and tax filings.
Retainage is recorded separately from standard receivables and payables to ensure accurate reporting of withheld amounts. We track retainage by job and reconcile it regularly to prevent lost revenue or delayed collections. This keeps cash flow projections realistic and avoids surprises at project closeout.
Yes. We specialize in construction accounting clean-ups. This includes correcting job misallocations, reconciling retainage balances, rebuilding WIP schedules, adjusting revenue recognition, and ensuring payroll and subcontractor costs are properly coded. Our objective is to rebuild financial integrity without disrupting ongoing operations.
We implement structured workflows and internal review checkpoints before transactions are finalized. All expenses, payroll allocations, and subcontractor bills are reviewed against job numbers and cost codes. Monthly reconciliations and management reviews further verify accuracy. Systems and discipline prevent misclassification.
We support construction-focused accounting platforms including QuickBooks Online, Foundation, Sage, and other systems commonly used by contractors. We also integrate accounting software with construction management tools such as ServiceTitan, Knowify, and similar systems to ensure financial data aligns with field operations.
Yes. We frequently coordinate with external CPAs and tax advisors. We ensure financial statements, WIP schedules, payroll data, and supporting documentation are prepared in a format suitable for tax filing and compliance. Our role is to strengthen the financial foundation so your tax professionals can operate efficiently.
Books are closed monthly. Each close includes reconciliations, job cost review, WIP adjustments where applicable, and management reporting. We then conduct structured financial reviews to analyze profitability, cash flow, and job performance. This ensures decisions are based on current and accurate financial data.
