What would a generated utility payment-plan environment contain at the moment of a missed instalment?

A residential customer's winter bill came in at $1,260.00, and the billing team set up plan `PLAN-5521` with six monthly instalments of $210.00. The second instalment's direct debit has just failed.

**Roles:** a billing agent handles the case, and a hardship coordinator approves plan changes for customers flagged as concession holders.

**Starting state a task pack could load:**

- Agreement `ACC-9034` with the invoice and usage period. - Schedule `SCH-5521` version 1, lines `L1` paid, `L2` failed, `L3` to `L6` pending. - Event `EVT-8812`, a dishonoured debit with a bank reason code. - Customer flag `CONC-Y`, which triggers coordinator approval for any extension. - Policy `POL-PLAN-4`, which allows a plan to be extended by at most two months, and requires a retry before any change. - A new request `REQ-1180`, where the customer asks to pay the failed amount with the next instalment.

**Required change:** retry the debit as policy requires, then, if it fails again, request coordinator approval and create version 2 of the schedule. Line `L2` is merged into `L3`, making it $420.00, and the plan runs to its original end date.

**Consequence:** merging without approval, or merging after the extension limit, leaves the plan in breach of `POL-PLAN-4`.

**What it teaches:** an environment needs events, flags and policy together. A table of instalments alone cannot show whether the agent followed the right sequence.
