What to provide

The plan change export, the proration policy and the resulting invoices.

Workflow

  1. List plan changes in the period.
  2. Recompute the expected proration per change.
  3. Flag charges that deviate from the expected proration.
  4. Return the check without issuing credits.

Output contract

Customer | change | expected proration | charged | flag | reviewer

Fictional acceptance test

Fictional month: 9 plan changes; 7 prorate correctly and 2 charged the full new price with no proration. Flag 2 charges.

Review gates and limits

Re-check the proration policy in effect at the change date. Credits or corrections are proposed for review, never issued by this check.
