Solna will automatically number your invoices sequentially but you can also enter your invoice number manually. Please note that different numbering formats will not be updated automatically and you'll need to make the changes manually each time.
You can edit your invoice number in the following manner:
- Create or Open an existing invoice.
- Click and edit the numbering sequence on the top right hand corner
- Save or Send invoice.
Note: You cannot create an invoice with the same number.
