Customising Invoice Numbers

Invoice numbers are automatically generated in sequence. However, you can easily customise these numbers, which is particularly useful if you are migrating from another invoicing system.
1

Use pre-populated invoice numbers

When you create a new invoice, the system will automatically suggest the next available invoice number in sequence. You can simply use this default number.
2

Change the invoice number

If you want to use a different number, type your desired number into the Invoice Number field. After you save, this new number will become the starting point for all future sequential invoices.
After saving, the new number becomes the starting point for future sequential invoices. Make sure this is intentional.
3

Add a prefix

To add a prefix such as “Inv-” or “Invoice-”, type it directly into the Invoice Number field before the actual number.
4

Ensure no duplicate numbers

The system will not allow you to use an invoice number that is already in use. Each invoice must have a unique identifier.
The system rejects duplicate invoice numbers. If you try to use an existing number, you will be prompted to choose a different one.
You can include letters, numbers, and other characters in your invoice numbers for maximum flexibility.
