Understanding AIA G702/G703: A Guide to Pay Application Auditing

The AIA G702 (Application and Certificate for Payment) and G703 (Continuation Sheet) are the backbone of construction payment processing. Yet many GCs approve pay applications without thorough auditing, relying on trust rather than verification.

Common Pay App Red Flags

Front-loading is the most common form of pay application manipulation. A subcontractor inflates early billing percentages, collecting more money upfront than the work warrants. By the time the project reaches substantial completion, the GC has overpaid — and the sub has less incentive to finish punch list items.

The 25-Point Rule

A reliable detection heuristic: flag any line item showing a completion percentage jump of more than 25 points in a single billing period, especially on items representing 5% or more of the total contract value. This pattern is a strong indicator of front-loading.

Mathematical Verification

Every G703 continuation sheet should be mathematically verified: line items should sum to the correct totals, retainage calculations should be consistent, and cumulative totals should match the G702 summary. These checks are tedious by hand but trivial for software.

Building a Verification Workflow

An effective pay app audit workflow combines automated math verification with human judgment on contextual items. The automation handles the repetitive checks; your team focuses on schedule-of-values alignment and change order integration.
