# AIA Billing

AIA billing is the standard way construction companies bill their customers for work completed on a project. ProForge Core handles the paperwork so you can focus on the work.

## What Is AIA Billing?

AIA stands for the American Institute of Architects, and they created standard billing forms used across the construction industry. The main form is the **G702**, which is a one-page summary that shows:

* The original contract amount
* How much has been completed to date
* How much retainage is being held back
* The amount due this period

Behind the G702 is a **continuation sheet** (sometimes called the G703) that breaks down every line item -- showing the scheduled value, what was completed in previous periods, what was completed this period, and what materials are stored on site.

In plain terms: the G702 is the cover page that says "here is what you owe us," and the continuation sheet is the backup that shows how you got to that number.

## What You Can Do

1. **Create an AIA bill** from any project with a few clicks.
2. **Enter completion percentages** for each line item so the math is calculated for you.
3. **Track retainage** -- the amount the customer holds back until the job is done.
4. **Add change orders** when the scope of work changes.
5. **Print or PDF** the G702 form and continuation sheets to send to your customer.
