What is a payment application? A beginner's guide for subcontractors
If you’ve mostly done residential or small commercial work, your billing was an invoice: “work done, amount due.” Then you land your first real commercial project and the GC says “submit your pay app by the 25th”, and hands you a package with more columns than a tax return. Here’s the plain version.
What it is
A payment application (pay app) is a formal, structured request for payment on a construction contract, submitted each billing period, almost always monthly. Unlike an invoice, it doesn’t just state an amount; it proves the amount from an agreed breakdown of the whole contract.
Why GCs insist on it
The GC is assembling your number with every other sub’s into one draw request for the owner and the bank. The bank wants everything to reconcile: what was the contract, what’s complete, what’s stored, what’s held back, what was already paid. A free-form invoice can’t feed that chain; a structured application can.
What’s in the package
- The application summary (commonly G702-style): contract sum, change orders, total completed, retainage held, previous certificates, and the headline, current payment due.
- The continuation sheet (G703-style): every line of your schedule of values with previous billings, this period’s work, stored materials, percent complete, and balance to finish.
- Backup as your contract requires: stored-material invoices, lien waivers, sometimes certified payroll.
The monthly rhythm
- Walk the job near cutoff; agree percent complete per line (often with the GC’s PM, the “pencil copy” round).
- Fill the continuation sheet; the summary derives from it.
- Submit by the GC’s cutoff with backup attached.
- The GC certifies, sometimes less than you applied for.
- Payment arrives minus retainage (usually 5–10% held until closeout).
- Next month starts from the certified history, not what you asked for.
Two terms you’ll hear immediately: retainage (the holdback, full guide here) and schedule of values (the line-item breakdown everything bills against, how to build one here).
Start with the structure, not a blank sheet
The fastest way to learn the format is to work a period in a correctly structured workbook, our free template is exactly that, with the math locked so a beginner can’t silently break it.
