Document Numbers

instellix assigns every finalized document a unique document number from a configurable counter.

Number strategies define which documents share a number sequence:

• Default — one tenant-wide sequence for all documents.
• Document type separation — separate sequences per document type (e.g. invoices vs. credit notes).
• Billing group separation — separate sequences per billing group.
• Service country separation — separate sequences per service country.

Counters and strategies are managed via the Billing Configuration API — see Document Number Configurations.
