# Continuation Sheets

The continuation sheet is the detailed backup behind your AIA bill. It lists every line item on the project and shows exactly how much work has been completed and billed for each one.

## How It Works

Each row on the continuation sheet represents a line item from your project (tied to a cost code or a description of work). The columns track the full billing history for that item across every pay application. When you fill in the current period, the system updates the totals automatically.

Here is what each column means:

* **Item Number** -- the line number, assigned automatically.
* **Description of Work** -- what the line item covers (e.g., "Rough Framing," "Electrical Rough-In").
* **Scheduled Value** -- the total contract amount for that line item. This is the budget for this piece of work.
* **Previous Applications** -- how much was billed in all prior pay applications combined.
* **Completed This Period** -- how much work was completed during the current billing period. You enter this as a dollar amount or a percentage.
* **Materials Presently Stored** -- the value of materials delivered to the site (or stored off-site) that have not been installed yet. This lets you bill for materials you have purchased even if they are not in place.
* **Total Completed and Stored** -- the sum of previous applications, this period, and materials stored.
* **Percentage Complete** -- total completed and stored divided by the scheduled value.
* **Balance to Finish** -- how much is left to bill on this line item.
* **Retainage** -- the amount held back on this line item (usually 5% or 10% of the total completed).

## Steps

1. Open an **AIA Bill** and scroll to the **Continuation Sheet** section.
2. Each line item is pre-filled from the project. If you need to add a line, click **Add Row**.
3. For each line item with progress this period, enter the **Completed This Period** amount or percentage.
4. If you received materials that are on site but not installed, enter the value in **Materials Presently Stored**.
5. Review the running totals -- the system recalculates everything as you type.
6. Click **Save** when finished.
