Construction billing and progress payment control
A construction invoice must reconcile the approved schedule of values, earned progress, retainage, prior billings and authorized changes.
Match the contract
Use the approved billing breakdown and verify completion percentages before issuing a payment request.
Track retainage carefully
Retainage may depend on contract terms, statutory limits, stored materials and project stage. Calculate withholding and prior payments separately.
Connect billing to project records
Keep the invoice, supporting documents, change approvals and status associated with the correct project rather than a disconnected spreadsheet.
