Construction and Trades bookkeeping has to reflect projects, phases, change orders, progress billings, retainage, field labor, subcontractors, equipment, and overhead. A generic transaction list can show cash moving, but it cannot explain whether the operating records, bank activity, and ledger agree.
This guide focuses on closing the books in a controlled sequence so reports are timely and reviewable. It is a bookkeeping workflow, not tax, legal, assurance, or regulated professional advice. Policies and jurisdiction-specific decisions should be approved by the business and its appropriately qualified professional.
Before the Close Starts
Set a cutoff for source records and confirm that the period, entities, accounts, and operational systems in scope are known. Ask whether there were new accounts, financing, major purchases, disposals, new locations, unusual refunds, or changes in how the business operates.
The close package should begin with these records:
- signed contracts and approved change orders
- estimates, budgets, cost codes, and purchase orders
- timecards and payroll registers
- supplier invoices and subcontractor bills
- pay applications, customer receipts, and retainage schedules
- equipment invoices, loan statements, and disposal documents
Step 1: Complete Transaction Intake
Post or import the period’s activity, resolve obvious duplicates, and identify transactions that lack sufficient support. Do not guess at material classifications. Place questions in an exception log with the date, amount, account, source, and decision needed.
Step 2: Reconcile Cash and External Balances
Reconcile every bank, credit-card, loan, payment, and material clearing account through the final statement date. Investigate old outstanding items, transfers recorded on only one side, duplicated feeds, and deposits that do not match source reports.
Step 3: Tie Operations to the Ledger
Perform job-cost and progress-billing reconciliation using approved estimates, change orders, time records, vendor bills, pay applications, bank activity, and the job-cost ledger. The source total, reconciling items, and ledger balance should be visible in one schedule.
Step 4: Reconcile Payroll and Payables
Tie job-coded field time, office payroll, overtime, reimbursements, benefits, and payroll liabilities to payroll registers, cash withdrawals, and liability balances. Review unpaid vendor items, credits, duplicates, and payments issued after cutoff.
Step 5: Review Assets, Debt, and Other Schedules
Update records for vehicles, tools, heavy equipment, financed purchases, lease records, repairs, and disposals. New financing should tie to executed documents and cash received or paid. Keep bookkeeping schedules separate from depreciation methods, capitalization policies, and other decisions that require professional approval.
Step 6: Perform an Analytical Review
Ask:
- Which projects changed scope this month?
- Do recorded costs agree with field and vendor records?
- Are billings, deposits, and retainage mapped to the correct jobs?
- Which open items could distort job margin or cash requirements?
Compare the current period with prior periods, expectations, and operational activity. A variance is a question—not automatically an error.
Step 7: Lock the Package
Deliver the reports, reconciliations, schedules, and open-item log together. Record who reviewed the close and prevent silent changes to a completed period. If a correction is later required, document what changed, why, who approved it, and which reports were reissued.
A Close Is Not Complete When…
- posting all materials to one general expense account
- recording deposits as ordinary revenue without reviewing the contract and accounting policy
- leaving payroll or equipment costs outside job reports
- using unsupported plug entries to force WIP or clearing accounts to zero
It is also incomplete when bank accounts reconcile but operational clearing accounts, payroll liabilities, receivables, payables, or asset schedules remain unexplained.
Practical Control Matrix
Use this table as a review aid, then adapt responsibilities and frequency to the business. In construction bookkeeping, the control design should reflect projects, phases, change orders, progress billings, retainage, field labor, subcontractors, equipment, and overhead.
| Control area | Evidence to retain | Review signal |
|---|---|---|
| Cutoff | The period, missing records, and late activity are identified. | Open items are not silently pushed into another month. |
| Reconciliation | External statements and supporting schedules agree with the ledger. | Material differences are explained rather than plugged. |
| Review | Reports include corrections, unusual movements, and unresolved questions. | Delivery status and approvals are recorded. |
Put the Guide Into Practice
- Establish the baseline. Confirm the period, source systems, accounts, responsible people, and last reliable reconciliation. List missing evidence before making corrections.
- Build the operating bridge. Document how estimating, time tracking, payroll, payables, project management, and accounting systems feed or reconcile to the ledger. Test the workflow on one complete period before scaling it.
- Measure completion. Review job profitability, committed cost, billings, retainage, cash, payroll by project, and WIP-supporting schedules. Record exceptions, decisions, and due dates with the monthly package.
The objective is not more paperwork. It is a smaller, stronger evidence trail that lets an owner, bookkeeper, and qualified reviewer reach the same explanation of a balance.
