Do two different invoice number formats also have to follow each other chronologically, or are they two separate series?
Example: I upload the self-generated invoice 25,001 to Dexxter. I now want to create a new next invoice on Dexxter itself (to send via Peppol). Does that invoice start at 2025-1? Or 2025-2?
Or can I change the Dexxter format to my own format?
