How AIA Payment Applications Work and What They're Used For
What an AIA Payment Application Is
An AIA Payment Application is a standardized form that contractors, subcontractors, and material suppliers use to request payment for work completed or materials delivered on a construction project. AIA stands for the American Institute of Architects, the organization that created and maintains these forms. The payment application documents what work was done, what it cost, and what portion of the contract price has been earned so far.
The form serves as the official request that moves money through the construction payment chain. A general contractor fills one out and sends it to the project owner or their representative (often an architect or engineer). That person reviews it, certifies the work was actually done, and then authorizes payment. Without an approved AIA Payment Application, money typically does not move.
These forms are used on projects of all sizes—from small renovations to large commercial builds—because they create a clear, documented record of what has been paid and what remains owed. They protect everyone involved by making the payment process transparent and traceable.
Key Takeaways
- An AIA Payment Application is the official request form contractors use to get paid for completed work, and it must be reviewed and approved before payment is released.
- The form tracks cumulative work completed and payment received, so it shows both what has been paid to date and what is still owed on the contract.
- Architects, engineers, or project managers typically review and certify the application before it goes to the owner or lender for payment authorization.
- Subcontractors and material suppliers often submit their own applications to the general contractor, who then includes those amounts in the general contractor's application to the owner.
- Disputes over payment applications are common and usually center on whether work was actually completed, whether it meets contract specifications, or whether retainage (holdback) was calculated correctly.
The Standard AIA Form and Its Sections
The most commonly used form is AIA Form G702, paired with AIA Form G703 (the continuation sheet). These forms have been updated several times; the current versions are from 2017. The form is divided into clear sections that track money from the beginning of the project to the current payment period.
The top of the form identifies the project, the parties involved, and the contract amount. Below that are columns for the original contract sum, previous applications, the current application, and totals to date. Each line item represents either a phase of work or a specific trade (framing, electrical, plumbing, and so on). The form calculates what percentage of the total contract has been completed and paid.
Near the bottom is a section for retainage—money the owner holds back as security until the project is finished. Retainage is usually 5 to 10 percent of the payment due, though the contract specifies the exact amount. The form also includes a certification line where an architect or engineer signs to confirm the work shown has been performed and meets the contract documents.
How Payment Applications Move Through the Construction Chain
Payment applications flow in a specific order, and understanding that order helps explain why approval takes time. A subcontractor or material supplier first submits their application to the general contractor, showing what they have completed and what they are owed. The general contractor reviews these applications, verifies the work was done, and then combines all of them into a single application to the project owner.
The owner's architect or engineer then reviews the general contractor's application. They visit the site, inspect the work, and confirm that what is shown on the application actually exists and meets the contract specifications. If there are discrepancies—work that was not done, work that does not meet standards, or damage—the architect notes these and may reduce the payment amount or ask for corrections before certifying.
Once the architect certifies the application, it goes to the owner or the owner's lender (if the project is financed). The owner or lender then authorizes payment, which is usually sent directly to the general contractor. The general contractor then pays the subcontractors and suppliers who submitted applications to them. This chain can take two to four weeks from submission to final payment.
Common Reasons Payment Applications Are Delayed or Rejected
Payment applications are rejected or held up for several reasons, and most of them center on documentation or discrepancies between what is claimed and what actually exists. If an architect visits the site and finds that work shown on the application has not been completed, or if completed work does not meet the contract specifications, the application will be sent back with notes about what needs to be corrected or removed.
Missing documentation is another frequent cause of delay. Subcontractors must provide proof of payment to their own suppliers and workers before the general contractor will include their amounts in the application to the owner. If a subcontractor has not paid their workers or suppliers, the general contractor may hold that portion of the payment until proof is provided. This protects the owner from liens filed by unpaid workers or suppliers.
Disputes over retainage also cause delays. If the contract specifies that retainage should be released at a certain point—for example, when the project is 50 percent complete—but the parties disagree on whether that milestone has been reached, the application may be held pending clarification. Similarly, if there are change orders (modifications to the original contract) that have not been signed by all parties, the amounts for that work may be withheld from the application until the change order is finalized.
What Information You Need to Complete an AIA Payment Application
To fill out an AIA Payment Application accurately, you need the original contract, any change orders that have been signed, records of all work completed to date, and documentation of all payments received so far. You also need the contract amount broken down by phase or trade, so you can show how much of each category has been completed.
If you are a subcontractor submitting to a general contractor, you need your subcontract amount, a description of the work you have completed in the current period, and proof that you have paid any suppliers or workers you hired. If you are a general contractor submitting to the owner, you need all of the subcontractor applications you have received, proof that you have reviewed them, and your own documentation of any work you performed directly.
You will also need the name and contact information of the person who will review and certify the application—usually the architect or engineer. Some owners require additional documentation, such as photos of completed work, test reports, or proof of permits. Check your contract or ask the owner's representative before submitting to avoid delays.
Retainage and How It Affects Payment
Retainage is money the owner withholds from each payment as a security deposit until the project is complete. It is not a penalty; it is a standard practice in construction to ensure the contractor finishes the work and fixes any defects. The contract specifies the retainage percentage—commonly 5 percent, sometimes 10 percent—and the AIA form calculates it automatically once you enter the payment amount.
For example, if a payment application shows $100,000 in completed work and the contract specifies 5 percent retainage, the contractor receives $95,000 and the owner holds $5,000. That $5,000 stays with the owner until the project is substantially complete and any punch-list items (minor remaining work) are finished. At that point, the owner releases the final retainage payment.
Some contracts include a clause that reduces or eliminates retainage once the project reaches a certain completion percentage—often 50 percent. If your contract has this clause and you believe the project has reached that milestone, you can reference it in your payment application and request that retainage be reduced or removed going forward. The architect will confirm whether the milestone has been met.
Disputes and What to Do If Your Application Is Rejected
If your payment application is rejected or held, the reviewer should provide written reasons. Common reasons include incomplete work, work that does not meet specifications, missing documentation, or disputes over change orders. Read the rejection carefully and determine whether the issue is factual (the work truly was not done or does not meet standards) or a disagreement about interpretation.
If the issue is factual, correct the application by removing or reducing the amounts for work that was not completed or does not meet standards. If the issue is a disagreement—for example, you believe the work does meet standards but the architect disagrees—you have the right to request a meeting with the architect and the owner to discuss. Bring photos, test reports, or other documentation that supports your position.
If the dispute cannot be resolved informally, your contract likely includes a dispute resolution process. This may involve mediation, arbitration, or a formal claim. Before pursuing that route, try to understand the reviewer's specific concern and whether there is a way to address it—for example, by having a third-party inspector verify that the work meets standards, or by agreeing to correct minor defects and having retainage cover the cost of corrections.
Frequently Asked Questions
Can I submit a payment application if work is not finished?
Yes. Payment applications are submitted monthly (or at intervals set by the contract) regardless of whether the project is complete. You include only the work that has been completed in the current period. The form tracks cumulative completion, so previous applications show what was paid before, and the current application shows only new work completed since the last application.
What happens if the architect refuses to certify my application?
If the architect refuses to certify, they must provide written reasons. You then have the right to request a meeting to discuss the issues. If you disagree with the architect's assessment, your contract may allow you to submit a written response or request a third-party inspection. If the dispute cannot be resolved, you may pursue a formal claim, though this is time-consuming and expensive.
Do I have to use the AIA form, or can I use my own?
Most construction contracts specify that AIA forms must be used, so check your contract. If the contract does not specify, you and the owner can agree to use a different form. However, using the standard AIA form is simpler because everyone in the industry knows how to read it, and it reduces disputes over format or missing information.
When does retainage get released?
Retainage is typically released after the project is substantially complete and any punch-list items are finished. The contract specifies the exact conditions for release. Some contracts release retainage in two parts: half when the project is substantially complete, and the other half after final inspection and approval. Ask your owner or architect when you can expect retainage to be released.
Can I submit a payment application if I have not paid my subcontractors yet?
You can submit it, but the general contractor or owner may hold that portion of the payment until you provide proof that subcontractors have been paid. This protects the owner from liens. If you are short on cash, discuss a payment schedule with your subcontractors and provide the general contractor with a written agreement showing when payment will be made.
