Payment Application

In Plain English

The monthly invoice package the contractor submits to request payment for completed work.

Definition

A payment application (pay app) is the formal monthly invoice submitted by a contractor to the owner or construction lender requesting payment for work completed and materials stored during the billing period. It includes a completed schedule of values (typically AIA G702/G703), conditional lien waivers, stored material documentation, and any approved change orders. The architect certifies the amount due before the owner releases payment.

Why It Matters in Bidding

The payment application is the contractor's primary cash-flow mechanism, so how a bid's schedule of values is structured directly determines how quickly costs are recovered and whether retainage and stored materials are billable. Because the architect certifies each pay app and lenders rely on it for draws, errors, missing lien waivers, or aggressive front-loading can delay payment and strain a contractor's working capital across the project.

Example

The contractor submitted its June payment application using AIA G702 and G703 showing 35 percent completion, attached conditional lien waivers and stored-material invoices, and the architect certified $642,000 due after deducting 5 percent retainage.

Frequently Asked Questions

A complete pay app package usually includes the certification cover sheet and continuation schedule, often AIA G702 and G703, conditional lien waivers from the contractor and subcontractors, documentation for stored materials, updated change orders, and sometimes a progress schedule or photos. Missing or unsigned lien waivers are a leading cause of delayed payment, so contractors track them closely each cycle.
Retainage is a percentage, commonly 5 to 10 percent, that the owner withholds from each certified payment until substantial or final completion to ensure the work is finished. It reduces the net amount paid on every pay app, so contractors must carry that withheld cash in their project financing and plan for its release at closeout, including subcontractor retainage.
On AIA-style contracts the architect or engineer reviews the application, verifies that the billed percentages reasonably match observed progress and stored materials, and certifies the amount due. The owner then releases payment based on that certification. This independent check is why inflated or front-loaded pay apps are risky and why aligning the schedule of values with actual progress matters.
