Invoice numbering allows you to define the sequence of invoice numbers. Specify the number for the next invoice, and on every invoice after that the number will increase by one.
Invoice numbers are displayed on the invoice once it reaches the status selected for invoice number through tools > settings > invoice statuses. If an invoice that already has a number is deleted, the number may be used again on the next invoice. Otherwise, numbers that have already been used can't be used again.
- Hover on tools, click settings and click to open invoice numbering. Notice the last used invoice number is displayed, and the next invoice number is in an editable field.
- Click in the next invoice number field and enter a new number.
- And, click save.
