You can set prefixes and starting numbers for both single and recurring invoices.

Your invoice number format helps keep your invoicing organized and legally compliant. In Shine, you can customize the format to fit your preferences or reset the number sequence when needed.
 

Change your Invoice Number Format

1. Create a new invoice or open a draft
2. Click the pen icon next to the invoice number:
   • Edit the prefix (e.g., change "TEST" or "2025" to your preferred code)
   • Set the starting invoice number (e.g., 00100 or 5000)
3. Save your changes

Good to know

• Invoice numbers must be unique and follow a sequential order.
• You cannot change the number of an invoice that has already been sent or booked.
• Resetting the numbering (e.g. at the start of a new year) is allowed, as long as the sequence remains logical and continuous within the period.
