The invoice number format helps you keep your invoices organised and compliant with legal requirements. In Shine, you can easily adjust the format or restart the numbering whenever needed.
Adjust the number:
Create a new invoice or open an invoice draft
Click the pencil icon next to the invoice number
Update the prefix (for example, replace “TEST” or “2025” with your own code)
Set the starting number (for example, 00100 or 5000)
Save your changes
The new invoice number format applies only to future invoices. Existing invoices remain unchanged.
Good to know
Invoice numbers must be unique and follow a continuous sequence.
Invoices that have already been sent or posted can no longer be changed.
Starting a new invoice number sequence (for example, at the beginning of a new year) is allowed, as long as the sequence remains clear and gapless.
