Agree what complete means commercially
A project can be delivered while its financial work remains open. Obtain the relevant acceptance evidence, confirm any outstanding revisions or warranty commitments, and check the final billing milestone. Keep a project manager's completed status separate from confirmation that every financial obligation has been resolved.
Read the approved scope and amendments once more. List deposits, progress invoices, reimbursable costs, credits, and final charges. A final invoice should explain the remaining amount rather than simply repeat the original project fee.
Check costs that have not reached accounts payable
Ask project owners about work already performed by contractors and suppliers that has not yet been invoiced. Compare purchase commitments with received invoices and cancellations. Have the accountant assess any required accrual using the service evidence and reporting policy.
A project that appears to earn $8,000 before a late $3,000 production invoice has not necessarily improved because the supplier was slow to bill. Keep estimated unbilled costs distinguishable from confirmed invoices and clear the estimate when the actual bill is posted.
Reconcile the client balance
Match all invoices, applied deposits, successful payments, and approved credits. Identify disputed amounts and promised concessions. Do not mark the receivable settled because an account manager expects payment or because a payment link was sent.
For an illustrative $25,000 project, a $10,000 deposit and two later $7,500 invoices can settle the agreed fee if the deposit is properly applied and all payments succeed. Issuing a separate $25,000 final invoice without accounting for prior billing would create an unsupported balance. Follow the actual billing structure rather than this example where the contract differs.
Save the result and keep genuine obligations open
Prepare the final fee-to-cost comparison with approved changes, writeoffs, and material estimate differences. Label whether it includes overhead and whether costs remain provisional. Retain the supporting records in a location the next finance person can access.
Keep remaining collections, refunds, supplier disputes, or contractual obligations on a named follow-up list even after the delivery project is archived. Close the finance record when those items are resolved or handed to an ongoing process with a clear owner. Use the completed review to improve estimating, not merely to celebrate the delivery date.
