What Is AIA Billing (G702 / G703)?

Why does commercial construction bill on a specific form?

AIA billing is the American Institute of Architects standardized pay application format, the G702 summary and G703 continuation, used on most commercial contracts.

What it is

AIA billing refers to the standardized pay application forms published by the American Institute of Architects: the G702 application and certificate for payment (the summary), and the G703 continuation sheet (the line items against the schedule of values). Most commercial construction contracts require billing in this format because it gives owners and architects a consistent, certifiable document.

Why it matters

If your billing does not match the AIA format the contract expects, it gets bounced and payment slips a cycle. The G703 has to reconcile to the schedule of values and apply retainage correctly, or the architect will not certify it.

How it works

1. List the SOV on the G703

   The G703 continuation sheet carries each schedule-of-values line and its billed amount.
2. Bill by percent complete

   Each line bills the work completed this period and to date.
3. Apply retainage

   The forms carry the retainage withheld so the net payment is correct.
4. Summarize and certify on the G702

   The G702 summarizes the application for the architect to certify before payment.

Common mistakes

How Scaftra handles it

Scaftra generates AIA-format pay applications from the schedule of values: the G703 lines reconcile to the SOV, percent complete comes from the field, and retainage is applied by the contract, so the certified document matches the work.
