As construction projects become more complex, contractors must understand AIA invoices. The American Institute of Architects (AIA) billing forms, especially the G702 and G703, are industry-standard documents used to track project progress and ensure proper payment. These official forms help contractors create professional invoices accepted across the construction industry.
This article covers everything contractors need to know about AIA invoices from key components to common mistakes that cause payment delays. Using AIA invoice templates simplifies payment requests, improves cash flow, and reduces disputes, making it easier to secure larger contracts and public projects.
What Is an AIA Invoice?
An AIA invoice is a standardized payment application widely used in commercial and public construction projects, consisting of two main forms:
G702: Application and Certificate for Payment
G703: Continuation Sheet
The G702 summarizes the payment request for work completed during a billing period, including contract value, change orders, prior payments, retainage, and current payment due. The G703 provides a detailed breakdown of work completed, materials stored, and retainage by line item from the Schedule of Values (SOV). These forms are standard in projects using AIA A201 general conditions, ensuring transparency, consistency, and legal documentation for all parties.
Why Do Contractors Use AIA Invoices?
AIA invoices help project owners, contractors, and lenders maintain clear billing records. They standardize payment requests, improve communication, reduce disputes, and speed approvals. Supporting progress billing and contractual compliance, these invoices offer detailed cost breakdowns that enhance billing accuracy and cash flow management, especially for government and large private projects.
Benefits of Standardized Billing
Using official AIA forms like G702 and G703 brings clarity and consistency to construction projects. These forms simplify payment requests, improve cash flow, and reduce disputes by clearly tracking work completed, stored materials, and prior payments. Contractors benefit from faster approvals, while project owners gain better visibility, ensuring efficient payments and keeping projects on schedule.

How to Fill Out an AIA Invoice
Filling out AIA forms correctly is vital. Inaccuracies can delay approvals or trigger payment disputes. Here is a step-by-step breakdown:
Change Orders and Supporting Documentation
Change orders and supporting documents are crucial in AIA billing. Any contract changes must be documented and included in your payment request to reflect the project's current status.
Supporting documents like lien waivers, insurance certificates, and proof of materials stored on site verify your payment request and build trust with project owners. Including detailed breakdowns of completed work, stored materials, and approved changes helps prevent disputes and keeps payments on track.
Always attach all necessary change orders and supporting documents with each payment request to avoid delays and maintain transparency.
Frequently Asked Questions
Does AIA billing have to be done?
Not always, but a lot of the time it's needed by law or contract for commercial and government construction. A lot of lenders also like AIA billing forms for giving out loans.
Just what is retainage?
In building, retainage is the amount of money that is held back until the job is mostly or completely finished. Usually, 5–10% of the total amount is held back. This gives workers a reason to finish the job and take care of any items on the "punch list."
How often should invoices to AIA be sent?
Contractors usually send AIA bills once a month. The due dates for submissions should match the terms of the contract and the project's major goals.
Can I make AIA invoices with software?
Yes. A lot of tools, like Procore, QuickBooks with third-party AIA add-ons, or standalone AIA billing software, can help contractors make correct forms. Software can do calculations automatically, link job costs, and keep track of retainage.
Bookkeeping Tips for Contractors
To make AIA invoices, you need correct data, good paperwork, and good record-keeping. Maintaining organized contract documents and supporting documents is essential for accurate financial tracking and compliance. Making sure you have a well-organized method for sending invoices to contractors is very important. You need to:
Record in detail how much the job costs and any changes that are made.
Keep an eye on payments and funds held in trust.
Bring your project billing in line with your financial system.
If you use accounting software, make sure that your billing system is connected so that the current state of the project is shown. This makes sure that your financial reports are correct and ready for an audit.
Conclusion
To stay in compliance, get paid on time, and keep a healthy cash flow on construction jobs, you need to know how to use AIA invoices.
