Can I change how my invoice numbers look?

Choose an Invoice number style in Settings, Billing: the standard number, a number only like QuickBooks, your own letters or a custom pattern, and set the next number.

Short answer

Yes. Open Settings and the Billing tab, then find Invoice numbers. Invoice number style offers the standard style (like INV-2026-00114-A3F2), a number only like QuickBooks (114), your own letters in front of the number (like INV-00114) or a Custom pattern. Set the Next number to carry on from your old system, and save. Only invoices made after you save use the new style; existing invoice numbers never change, and nothing changes for your agency until you pick a style.

Step by step

  1. Open Settings and the Billing tab.
  2. Under Invoice numbers, choose an Invoice number style.
  3. Enter your letters or pattern if the style uses them, and the Next number.
  4. Save, then create an invoice to see the new number.

Good to know

  • Keep it to 21 characters or fewer so QuickBooks can use it as the invoice number.
  • If invoices were made after you opened the page, AveeCare asks you to continue from the newest number so no number is used twice.
