- Go to Finances > Level Billing.
- Find the agreement, open its row menu (⋮) and choose Extend. You can also open the agreement and click Extend Contract.

- In Add How Many Invoices?, enter how many more invoices to add. Each invoice covers one billing period: a month, a week or a year, depending on the agreement.

- Check After Extension, which shows the New End Date, Total Invoices and New Contract Total.
- Click Extend Contract. In the Confirm Extension box, click Yes, Extend.

Example: a monthly agreement ending July 1. Adding 2 invoices moves the end date to September 1, with two more invoices at the same amount.
