Invoice error messages and what they mean

Last updated: 2 Nov 2026

The invoice form checks your entries before saving. The message tells you what to fix. Your item rows are kept when an error shows.

Steps

1. "Buyer name is required." Enter the buyer's name.
2. "Your business name is required on a tax invoice." Fill your business name.
3. "Add at least one item." Add an item with a description and rate.
4. "This invoice is already Paid and cannot be changed." Paid and Cancelled invoices are final.
5. "Could not save the invoice. Please try once more." Click Create invoice again.

Common mistakes

• Clicking Create invoice many times quickly.
• Leaving the rate empty on an item line.
