Invoice number
Warning
Invoice requirements vary by region. Please consult with your tax advisor on your specific use case. The responsibility that your invoices meet applicable tax requirements lies with you.
Billwerk+ Optimize automatically generates invoice numbers for accounting purposes (that's why they are called “Invoice accounting numbers”). Once you turn on invoice number creation, invoice numbers will be assigned to new invoice documents.

You can configure how your invoice numbers should look like:
Sequence counter type: You can decide to reset your invoice numbers periodically. You have the choice of monthly resets, yearly resets or no resets at all. For the yearly sequence counter type, the reset happens on January 1st. For the monthly sequence counter type the reset happens on the first day of each month. After the reset date the counter starts afrom the “Invoice number after reset”.
Digits count: You can configure the fixed minimum number of digits for your invoice numbers. Leading zeroes will be added for lower numbers to ensure the configured digit count. If there are more invoices that can't be accommodated within the selected digit count, we will keep counting up.
Invoice sequence prefix: By default the prefix "IN" is assigned but you can customize it. If you change the name of your sequence it will be applied from the next invoice on.
Dynamic placeholder: You can add a placeholder that indicates the date, month and year of the invoice. Choose one of several formats.
Next invoice number: Your next invoice will be issued with this number. It will automatically increase by one with each invoice issued.
Invoice number after reset: If you have chosen to reset your invoice numbers periodically, you can choose what number to restart the counter from after the next reset.
Credit note number
Per default, credit notes share the same sequence as invoices. However, you can chose to assign credit notes to a separate number sequence.
![]() |
Credit note sequence prefix: By default the prefix "CN" is assigned, but you can opt for a custom prefix. If you change the prefix, it will be applied from the next credit note on.
Notice
Digits count and dynamic placeholders within the credit note number sequence are the same as for the invoice number sequence.
Next credit note number: Your next credit note will be issued with this number. It will automatically increase by one with each credit note issued.
Notice
Reset for credit note numbers happens simultaneously with the reset of the invoice numbers.
Next credit note number after reset: Chose what number to restart the counter from after the next reset.
