Take me through a bill cycle, then tell me what the invoice looks like when a customer changes plan mid-cycle and disputes the result.
A cycle closes a period, assembles recurring, usage and one-off charges, applies discounts and tax, then issues an invoice that must never be edited afterwards. A mid-cycle change produces a credit for unused advance rental plus a prorated new charge, which is what customers dispute.
The monthly bill run dies two thirds of the way through and the cycle closes tomorrow. What do you do?
Restart rather than rerun. The run is not a transaction but a sequence of per-account commitments, so each account must be either fully billed or untouched, charge assembly must be deterministic from inputs frozen at cut-off, and quarantining the offending accounts beats missing the cycle.
Marketing want to raise the price of a plan a million subscribers are already on, and change what it includes. What has to happen in the catalogue?
Three separate requests hide in that sentence. Pricing new sales is a new catalogue version; repricing the base is a commercial migration per subscription with notice; changing contents is both. The usual defect is not an edited offering but a shared object one level down that both versions reference.
A subscriber goes abroad and their roaming charges only reach you days later. How does charging cope with that?
Roaming splits usage from its record: the visited operator meters it and sends files later, so postpaid rates on records that may miss the bill and prepaid cannot wait at all. The design turns on which usage you allow before you have proof of it, and what the delay costs when it is fraud.
