Dunning
The sequence of automatic reminders and consequences applied when a payment is late.
Dunning is the trade term for chasing money that is late — and, more usefully, for doing it as a fixed sequence rather than as a series of individual decisions. A dunning scenario says what happens and when: a reminder before the due date, a payment link on the day, a chaser afterwards, and finally a consequence such as an access block.
The value lies in the sequence being identical for everyone. Nobody has to decide whether this particular tenant deserves another week, and nobody has to remember who was chased last Tuesday.
An example. −3 days: an SMS. Day 0: an email with a payment link. +3 days: a chaser. +10 days: access blocked. A tenant who pays at any point drops out of the sequence automatically, and the sequence resumes only if they fall behind again.
Good dunning is quiet. Most tenants never reach the later steps, because the early ones arrive before they have forgotten.
