In compliance with Swedish laws, an invoice number must be provided on all invoices and consist of an unbroken series of numbers, this so that the Swedish Tax Agency can verify that all invoices have been correctly issued.
The invoice number you start at is entirely up to you. If you do not set a specific number, your first invoice will be given the invoice number 1. The following invoice numbers will then be 2, 3 and so on.
If you already have an invoice number series you should set the next number in the series when you create your first invoice under Billing Terms and Conditions for Invoice number. After that, Billogram will automatically count onwards from that number.
