User Stories (Prime Overdue)

As billing, I upload the monthly MT940 so return debit notes become debts on the right contracts.
As collections, I open the debt list and filter customers whose internet is already blocked.
As finance, I clear an open debt when a customer transfer arrives with the invoice number in the reason.
As accounting ops, I import a DATEV/EuroFiBu CSV of still-open debts instead of parsing the bank file in NMS Prime.
As finance, I run a test CSV upload to see who would be blocked before applying blocks.
As delivery, I choose MT940 or CSV mode for the tenant and document the transfer-reason rule for payments.
As billing, I configure return-debit fee and three dunning charge levels before the next settlement run.
As care, I open a contract’s debts from the debt list breadcrumbs and explain the open balance to the customer.
As ops, I review the import log for unmatched transactions and quick-add a debt when the match is clear.
As delivery, I set missing-amount / debt-count / indicator thresholds so chronic debtors lose internet on import.
