How do I configure auto-generation of invoice numbers?

To configure auto-generation of invoice numbers:

• Log in to your Zoho Books organization.
• Go to Sales on the left sidebar and select Invoices.
• Click + New at the top right corner of the page.
• In the next page, click the Gear icon next to the Invoice# field.
  
  

• Edit the prefix and the format of the next invoice number as preferred.
• Click Save.

The edited prefix and next number will be updated for the invoice and will continue being auto-generated for future invoices.
