How can I enter the invoice numbers manually?

In Zoho Invoice, by default, the system generates the invoice number. The default prefix for the invoice numbers is "INV". You have the option to enter these invoice numbers manually. To enter the invoice number manually:
  • Go to Settings ---> Invoice Preferences (under invoice settings)
  • Uncheck the Auto Generation option
  • Click the Save button
Note: To set the system back to auto-generating invoice numbers, you must check the auto generation option again.
