How the AIA Pay Application Process Works for Subcontractors

Pay applications are how subcontractors get paid on commercial construction projects. If you've worked on any job larger than a small renovation, you've likely encountered AIA pay app forms — and if you're filling them out wrong, you're delaying your own payment.

This guide explains the process behind the paperwork: what the G702 and G703 each do, how a pay application moves from your draft to the GC, the architect, the owner and back to you as a check, and the mistakes that send it back. The form itself lives elsewhere — our G702/G703-style pay application template is the Excel and PDF version with every line explained, and the free online pay app builder does the same math in your browser and rolls it forward each month. When you are billing several jobs at once, see how AIA billing software for subcontractors carries each application forward for you.

What Are AIA Pay Applications? G702 vs. G703

The American Institute of Architects (AIA) publishes standardized contract documents used across the construction industry. The two forms used for progress billing are:

• G702 — Application and Certificate for Payment. This is the cover sheet. It summarizes the total contract amount, work completed to date, retainage, previous payments, and the current amount due.
• G703 — Continuation Sheet. This is the detail. It breaks down the contract into line items (your schedule of values) and shows the work completed and materials stored for each line item.

Together, these two forms tell the GC and owner exactly how much work you've done, how much you've been paid, and how much you're requesting this period. Many GCs accept a G702/G703-style application rather than the licensed AIA documents; check your subcontract before the first one goes out.

The Monthly Pay Application Cycle

A pay application is less a form than a monthly routine with deadlines set by people above you in the payment chain. On a typical commercial job it runs like this:

1. The schedule of values is approved. Before the first application, the GC (and often the architect) reviews and approves your line items. Everything after this bills against those lines.
2. You send a pencil draft. Many GCs ask for a draft — a "pencil" — several days before their cutoff. Their project manager walks the job, compares your percentages to what is in place, and marks up anything they won't support.
3. You submit the final application with its backup. The agreed percentages go on the signed application, along with whatever the subcontract requires: lien waivers, stored-materials invoices, certified payroll on public work, insurance certificates.
4. The GC rolls it up. Your application becomes a line in the GC's own application to the owner, alongside every other trade's.
5. The architect or owner's representative certifies it. The certificate is the approval of an amount — it may be less than you applied for, and the difference is what you reconcile before the next cycle.
6. Money moves down the chain. The owner pays the GC, and the GC pays you on the terms your subcontract sets — pay-when-paid clauses are common — within any limits a state prompt payment law adds. Conditional and unconditional lien waivers trade hands along the way.

Then the next period starts, with this month's billed amounts carried into the "previous applications" column. That roll-forward is where spreadsheets break: one missed carry and every later application is off.

Setting Up Your Schedule of Values

The schedule of values (SOV) is the backbone of every pay application you'll submit on a project. It gets established at the start of the job and stays with you through the final payment. Getting it right upfront saves headaches for the entire project duration. If you priced the job in construction bidding software, the SOV should follow the bid's line items — otherwise you rebuild the contract in a spreadsheet every month. Our explainer on what a schedule of values is and how it changes goes deeper, and the schedule of values template is a blank one to start from.

Break your contract into meaningful line items that reflect actual phases of work. A mechanical sub might break theirs into rough-in, underground, above-ceiling, trim-out, and startup/commissioning. An electrical contractor might separate by floor, by system (power, lighting, fire alarm, low voltage), or by phase.

Tips for structuring your SOV:

• Front-load strategically, but don't overdo it. It's standard practice to weight early work items (mobilization, submittals, rough-in) slightly higher to improve early cash flow. But if your SOV is obviously front-loaded, the GC or architect will reject it.
• Include a mobilization line item. This covers your costs for getting set up on the job — temporary facilities, initial material deliveries, and coordination.
• Separate labor and materials if the contract requires it. Some owners want to see the split. Check your subcontract.
• Make line items match your work flow. You'll be billing against these items monthly, so they should align with how the work actually progresses.

How the G702 and G703 Numbers Connect

The G702 is a math exercise once the G703 is right. Its lines walk from the contract down to this period's check:

1. Contract sum to date — the original contract plus the net of approved change orders. Pending change orders don't count until they're approved.
2. Total completed and stored to date — the G703 column G total, carried over unchanged.
3. Retainage — the contract rate (often 5% or 10%) applied to that cumulative total, not just this period. Our retainage guide covers step-downs and release.
4. Less previous certificates for payment — what earlier applications already earned, net of retainage.
5. Current payment due — what's left. This is the number your lien waiver for the period should reference.

The template page breaks down all nine lines of a G702-style application with a worked example; the point here is the dependency. If a G703 line is wrong, every G702 line below it is wrong too.

On the final pay application, line items go to 100% and retainage is billed so the current payment due includes funds held throughout the job. That last G702 is one piece of the construction project closeout checklist — it typically will not be processed until the punch list, closeout documents, and lien waivers travel with it.

What the G703 (Continuation Sheet) Tracks

The G703 is where you track progress on each line item. For each row:

• Column A: Item number
• Column B: Description of work
• Column C: Scheduled value (from your approved SOV)
• Column D: Work completed from previous applications
• Column E: Work completed this period
• Column F: Materials presently stored (not yet installed)
• Column G: Total completed and stored to date (D + E + F)
• Column H: Percentage complete (G / C)
• Column I: Balance to finish (C - G)

The most important thing: your numbers need to be defensible. If you bill 60% on a line item, you should be able to walk the GC through the job and demonstrate that 60% of that work is actually in place. Overbilling erodes trust and leads to disputes.

Common Mistakes That Delay Payment

• Math errors. Sounds basic, but incorrect totals are the number one reason pay apps get bounced. Double-check every calculation before submitting.
• Missing backup documentation. Many GCs require lien waivers, certified payroll, stored materials invoices, or updated insurance certificates with each pay app. Know what's required and include it.
• Billing for stored materials without documentation. If you're billing for materials stored on-site or at a warehouse, you need invoices and sometimes photos. Some contracts require stored materials to be insured separately.
• Submitting late. Pay app deadlines are usually tied to the owner's billing cycle. Miss the cutoff by one day and you could wait an entire month for your money.
• Not matching the GC's format. If the GC uses a specific template or requires submission through a portal, use it. Submitting in your own format creates extra work for their AP team and pushes you to the back of the line.

Tips for Faster Approval

1. Submit early. Don't wait until the deadline. Submit a few days ahead so there's time for questions without missing the cycle. If your office reviews pay apps internally before they go out, build that approval step into your timeline.
2. Be conservative on percentages. It's better to bill 55% when you're at 58% than to bill 65% and get knocked back. Consistent, honest billing builds trust.
3. Communicate with the GC's project manager. A quick call before you submit — "I'm billing 70% on rough-in this month, does that align with what you're seeing?" — can prevent rejections.
4. Keep your change orders current. Don't let unapproved construction change orders pile up. Push for timely approval so your pay app reflects the actual contract value.
5. Track everything digitally. Using software to manage your pay apps eliminates math errors, keeps a clean audit trail, and makes it easy to generate the forms on demand.
