How to Bill in AIA Format: A Subcontractor's Step-by-Step Guide

Last updated: March 20, 2026

TLDR

Billing in AIA format means submitting a G702 Application for Payment backed by a G703 Continuation Sheet on a monthly or milestone basis. The G703 line items must match your Schedule of Values agreed at project start. Get the SOV wrong at project start and every AIA application downstream will be a fight.

DEFINITION

G702
AIA Application and Certificate for Payment — the cover page that summarizes the pay application. Shows contract value, change orders, total billed to date, retainage, and the amount due this period.

DEFINITION

G703
AIA Continuation Sheet — the line-by-line breakdown tied to the Schedule of Values. One row per SOV line item, with columns for scheduled value, prior billings, this-period billing, stored materials, and percent complete.

DEFINITION

billing cutoff date
The date each month by which you must submit your AIA application to be included in that month's payment cycle. Typically the 20th to 25th for a month-end payment cycle. Missing it means waiting another 30 days.

DEFINITION

stored materials
Materials delivered to site or an approved off-site location but not yet installed. Listed separately on the G703 and typically require documentation (delivery receipts, photos) for GC approval.
“Missing the GC's billing cutoff costs you 30 days of cash flow. On a $600,000 job at 10% retainage, that's $54,000 you're waiting an extra month to see.”
O. Mensah , Owner at Mensah Electrical
“We negotiate the billing cutoff date before we mobilize. Moving it from the 20th to the 25th gave us five extra days to get the G703 right and cut our short certifications in half.”
W. Johansson , Project Manager at Nordic Plumbing

Why the SOV Is More Important Than the Forms

Most subs treat the Schedule of Values as paperwork to knock out before mobilization. It is actually the document that controls your cash flow for the entire job.

Every line item on your G703 ties back to the SOV. If a line item is undervalued, you’ll be chronically underpaid on that work until the job closes — and retainage is held against the certified amount, so the shortfall compounds. If you front-loaded line items to collect cash early, expect the GC to push back on your percent-complete claims mid-job.

Set the SOV at realistic values, get it signed before work starts, and treat any change orders as formal SOV amendments. One hour spent negotiating the SOV at the project kickoff prevents months of payment disputes.

The Monthly Billing Cycle Timing

AIA billing runs on a predictable calendar. The GC posts a schedule at project start with the billing cutoff date, the GC review period, the owner approval date, and the payment date. A typical sequence: subcontractors submit by the 20th, the GC reviews through the 25th, the owner approves by the 30th, and payment goes out by the 30th of the following month.

That means your work completed in month one does not turn into cash until the end of month two at the earliest. On a large project with retainage held at 10%, your actual cash receipt is further reduced.

Know the full schedule before you bid. If the payment cycle is 60+ days and retainage is 10%, you need to fund that float. It changes the economics of the job.

When the GC Certifies Less Than You Applied For

Short certifications are common. Most of the time it is one of three things: the GC disputes your percent-complete on a specific line item, you’re missing documentation for stored materials, or there is a back-charge being processed against your contract.

Get the written reason before you accept the certified amount. Most construction contracts require you to submit a written exception within 14 to 21 days if you disagree with the certified amount. Missing that window can mean you’ve implicitly accepted the reduction.

Keep the documentation chain clean: save every G702/G703 submission with a time-stamped confirmation of receipt, every short-certification notice, and every written exception you file. If the dispute escalates to a payment bond claim or lien, that paper trail is your case.

Q&A

How do I bill in AIA format as a subcontractor?

Before work starts, get your Schedule of Values approved and signed by the GC. During the month, track actual costs by SOV line item. At billing time, calculate percent complete per line item (actual cost divided by estimated cost), fill in the G703 Continuation Sheet with current-period and cumulative amounts, then complete the G702 cover page and submit both by...

Q&A

What is the billing cutoff date in AIA billing?

The billing cutoff date is the monthly deadline for submitting your AIA pay application. On most commercial projects it falls between the 20th and 25th of the month. Applications submitted after that date are typically held for the following payment cycle, pushing your payment out by 30 days. Negotiate the cutoff date before work starts if the GC's standard date...

Can I change my Schedule of Values after the project starts?
Technically yes, but getting a GC to approve SOV changes mid-project is difficult. Most GCs will reject revisions that increase the front-loaded line items or otherwise improve your payment position. If you need to revise the SOV — for example, a major approved change order restructures the scope — document it as a formal change and get it signed before you submit the next application. Unilateral SOV changes will get your application rejected.
What documentation do I need for stored materials billing?
Standard requirements are: a delivery receipt or bill of lading showing materials arrived on site (or in an approved off-site storage location), a description matching the SOV line item, and photos of the materials in storage. Some GCs also require a stored materials waiver and conditional lien waiver before releasing payment for stored materials. Check the contract for specifics — requirements vary by GC.
What do I do if the GC certifies less than I applied for?
Request the architect's or GC's written reason for the reduction before accepting the certified amount. Common reasons: disputed percent-complete on a line item, missing stored materials documentation, or a pending back-charge. If you disagree with the reduction, document your position in writing immediately — most contracts have a short window (14-21 days) for written exceptions before the certified amount becomes accepted. Do not just cash the short check and move on without a paper trail.
