Question 100
A finance governance committee considers: A subscription customer receives a new contracted unit price midterm, but the billing schedule keeps the old amount. Which repeatable safeguard is most targeted?
Explanation
Correct Answer
Require a signed amendment before changing schedule pricing. This prevents recurrence of the identified mechanism: Price updates to billing schedules need effective dates and historical invoice preservation. Validate the control by checking: Future invoice lines use the new agreed rate while already-posted periods retain history.
Incorrect Answers
Validate milestone acceptance and billing triggers against the signed agreement. That safeguard is aimed at a different risk: A three-phase implementation contract requires billing milestones, but invoices are generated on a flat monthly frequency. It does not most directly prevent recurrence of: Price updates to billing schedules need effective dates and historical invoice preservation.
Run overlap detection before subscription renewals and upgrades. That safeguard is aimed at a different risk: A customer upgrades from a monthly to an annual plan, but its old schedule continues billing and overlaps the new contract. It does not most directly prevent recurrence of: Price updates to billing schedules need effective dates and historical invoice preservation.
Use positive and negative item tests before enabling default deferral behavior. That safeguard is aimed at a different risk: A finance admin marks every expense of one vendor as deferred, even though only certain item classes require deferral. It does not most directly prevent recurrence of: Price updates to billing schedules need effective dates and historical invoice preservation.
