AIA G702 Pay App Calculator

What is AIA G702?

AIA Document G702 is the industry-standard Application and Certificate for Payment used in construction. It provides a summary of the contractor's payment request, including the original contract sum, approved change orders, work completed, materials stored, retainage, and the net amount due for the current period.

Key G702 Line Items Explained

• Contract Sum to Date: The original contract amount plus (or minus) all approved change orders.
• Total Completed and Stored: Work completed in place plus the value of materials stored on-site or off-site.
• Retainage: A percentage (typically 5-10%) withheld from each payment as security for project completion.
• Current Payment Due: The net amount owed for this billing period after deducting retainage and previous payments.

Common Pay App Errors GCs Should Catch

• Math errors between the G702 summary and G703 line items
• Retainage calculated on wrong base amount
• Stored materials not supported by invoices or insurance
• Overbilling — completed percentage exceeds actual progress
• Missing lien waivers from previous payment periods
• Change orders included before formal approval

Why Automated Pay App Review Matters

Manual pay app review is one of the most time-consuming tasks in construction accounting. Each application must be cross-referenced against the schedule of values, change order log, and lien waiver status. Errors caught after payment result in costly back-charges and disputes.
