# Dunning / cobrança conventions (Master Prompt §6.9)

- Configurable rules as data, not hardcoded logic: X days before due date, on due date, X days after, escalations, suspension/alert where policy allows, channels and templates.
- n8n consumes dunning events without querying tables directly — publish via the transactional outbox (ADR-0009), event catalog owned by `eden-api-integrations`.
