Numbering Invoices

In this area, you determine how your invoices are automatically numbered.

• Prefix: Enter a unique abbreviation for your invoices (e.g. "I" for invoice).
• Next number: Set the number of the next invoice to start with. The number will automatically increase with each new invoice.
• Number format: Define how many digits the number should have (e.g. 0001 for four digits). The number will be filled with zeros accordingly.

In the "Preview" field, you can see directly how the next number of your invoice will look like (e.g. I0001).

Notes and tips

• The number format can be adjusted at any time.
• The numbering is continuous and ensures seamless documentation of your invoices.
• After changes, please click "Save" so that your adjustments are taken into account.
