Upcoming Release

Dunning during payment collection

You can now allow dunning to continue while payment collection is still in progress. This includes automatic collection attempts, payment retries, and an active PreBooked Item. Dunning intervals, the due date, dunning blocks, and a zero amount due still apply. Payment retries and PreBooked Items are not changed.

The option is off by default. Existing configurations keep the current behavior: dunning waits while payment collection is in progress.

For OPOS Case Dunning, the setting is in the webportal under Configuration > Billing > Dunning configuration. For document-based dunning, set dunnDuringPaymentCollection to true on POST /v2/billing/configuration/dunning. Document-based dunning has no webportal switch.

More details can be found in When Dunning Starts.
