Progressive invoicing on one invoice

How to add the next phase of work or edit unpaid lines on an issued invoice, what happens to the payment link, and what can block a change.

Progressive invoicing lets you keep billing a job on the same invoice. After an invoice is issued, you can add the next phase of work or change lines that are not paid yet. Every change is kept in the invoice's history, and earlier versions are never overwritten.

Owners, administrators, dispatchers, and office staff can make these changes.

Add work or edit lines

  1. Open the issued invoice from /invoices.
  2. Select Add work (or Edit invoice once it has been changed before).
  3. Edit unpaid lines, or use Add work in the editor to bill the next phase. A negative price adds a discount. Paid lines stay as they are.
  4. Check New invoice total, Paid and credited, and Balance due.
  5. Optionally fill in What changed (for your history, not the customer).
  6. Select Save changes.

The new total cannot be less than what has already been paid.
