What is Numbering in a personalized invoice?

Last updated: March 21, 2026

Document numbering lets you control the prefix and format of your document numbers. InvoiceOwl automatically assigns sequential numbers to new documents.

You can customize numbering for:

  • Invoice Numbers
  • Estimate/Quote Numbers
  • Purchase Order Numbers
  • Credit Memo Numbers

In the current version of InvoiceOwl, numbering is managed through the Template Designer:

  1. Click Settings in the left sidebar.
  2. Under the Documents section, click Template Designer.
  3. Use the designer to set prefixes and numbering formats for each document type.

On the Mobile App

Document numbering settings are currently only available on the web app.
