Oregon Construction Subcontractor Factoring: Progress Billings and Retainage

Construction subcontractors can complete measurable work well before an owner or prime contractor pays the related application for payment. That lag can challenge payroll, materials, equipment, and lower-tier obligations. Invoice factoring may be worth discussing for an earned, documented business receivable, but construction billing has special approval, retainage, and contract issues. QuickInvoiceFactoring.com helps match companies with providers; it is not a direct lender and cannot promise an invoice will qualify.

The first question is not just how much work was performed. It is whether the billing is contractually due, properly submitted, reviewed or approved as required, and not subject to unresolved backcharges or conditions. Public projects may also have project-specific forms, certified payroll, and payment procedures.

Approved progress billing versus unbilled work

A subcontract, notice to proceed, schedule of values, or purchase order is not a current invoice for completed work. Work in progress, stored materials that do not meet contract terms, anticipated change orders, and future milestones should not be presented as earned receivables. A progress application may qualify for review only to the extent it reflects completed work and satisfies the contract's billing and certification rules.

Separate the amount submitted from the amount approved, the amount currently payable, and retainage or other withheld sums. Retainage can be a real contractual receivable but may not be presently due or eligible under a provider's criteria. Never describe the retained balance as immediately collectible without checking the contract and approval status.

Prepare the payment application record

For each billed period, compile:

• Executed subcontract, prime contract provisions incorporated into it, schedule of values, and amendments.
• Approved change orders, written directives, and supporting quantities for any changed scope.
• Period application for payment with cutoff dates, line-item progress, prior billings, credits, and retainage shown separately.
• Field reports, measured quantities, inspection signoffs, delivery tickets, and photographs where they substantiate completed work.
• Prime contractor or agency review status, approved amount, correction notice, and record of the invoice's receipt.
• Conditional or unconditional waivers and releases required by the contract, plus lower-tier supplier documentation where applicable.
• Public-works certified payroll submissions and project records when required.

Oregon Department of Transportation's Construction Manual, Chapter 25, addresses payments to contractors and retainage; Chapter 26 discusses prompt payment and subcontractor payment obligations on ODOT work. Treat those chapters as guidance for ODOT contract administration, not as universal terms for every private job. BOLI's public works resources and the specific contract matter for project requirements.

Reconcile approval, retainage, and payment chain

Match the approved amount to the prime's breakdown. Identify reductions for quantity, schedule, documentation, or claims separately from accepted balances. Confirm what is approved, under review, held as retainage, and when the payment clock starts under the governing agreement and law.

A certified progress application may establish work performed without proving that the full sum is due today. Keep earned current billing, approved-but-unpaid amount, retainage, disputed extras, and unapproved change work in distinct ledger categories. A purchase order authorizing a subcontract's maximum value is not evidence that the scope has been completed or accepted.

Questions to ask a factoring provider

Ask whether it reviews construction and public-works receivables, what approval evidence it requires, and whether partial billings or retainage qualify. Clarify its treatment of pay-when-paid language, bonds, joint checks, waivers, backcharges, change orders, and notice requirements. Ask about assignment approval, liens, recourse, reserves, fees, and customer notices. Have counsel review the contract before changing remittance instructions.

Submission check: completed scope, properly submitted billing, identifiable approval, reconciled deductions, and a separate retainage amount. This gives a provider a clearer basis to assess the actual receivable than a contract value or projected schedule of work.
