Field note
Credits that feel fair can still break contract language
Customer success teams issue credits because a feature lagged, an outage annoyed a key account, or a competitor quote appeared mid-term. Those reasons are legitimate commercially. For a subscription billing audit, the question is narrower: did the credit follow the policy the contract and public terms describe?
We compare credit memos to the published bands — percentage caps, eligible plan types, and whether credits reduce future invoices or require cash refunds. When ops staff invent a one-off amount above the band, the finding is not moral judgment; it is a control gap that finance must either ratify or reverse.
Proration credits deserve special attention. An upgrade mid-cycle should leave a clear trail from unused days on the old plan to charged days on the new plan. Mixed currencies or tax-inclusive pricing in Taiwan and export markets make that trail longer, which is why we recalculate a dedicated proration sample rather than relying on system totals alone.
Teams that keep a short credit log — reason code, approver, policy clause cited — finish remediation faster. The audit then becomes a confirmation exercise instead of forensic reconstruction from chat threads.
