1.1. What it is

Debt list: open outstanding amounts per contract with fees, due dates, dunning indicator, internet-blocked / SEPA flags
Import: SWIFT/MT940 bank files or CSV from financial accounting (EuroFiBu / DATEV)
Clearing: settlement-run debts, SEPA auto-clear, manual payment against a parent debt
Config: return-debit fees, payment period, dunning charges/texts, internet-block thresholds

Works with: Prime Billing (invoices / settlement / SEPA) · OS Provisioning (contracts / internet access).

1.2. FAQ

Use MT940 when NMS Prime should own bank-file matching and debt history. Use CSV when financial accounting already runs dunning and you only need open-debt visibility (and optional internet blocks) in NMS Prime.

It stores dunning charges and text blocks and tracks indicators. Fully automated letter production is typically handled in external accounting / print processes — see Feature List out-of-scope.

On debt import, when configured thresholds for missing amount, open-debt count, or dunning indicator are exceeded (test CSV mode previews without blocking).

Invoices, settlement run, SEPA mandates, and cost centers — Overdue attaches debts to that billing lifecycle.
