Billing Migration Acceptance Criteria: Make Ready Measurable

Billing migration acceptance criteria: what to decide
Everyone says the migration looks good, yet nobody agrees what would block launch. Write the acceptance criteria before the final rehearsal so the decision is based on evidence rather than deadline pressure.
Use representative contracts and explicit boundary cases. Determine who approves finance, product and operational checks. Set an exception process, but do not treat unexplained monetary differences as acceptable merely because the aggregate percentage is small.
How this works in practice
A team might require every active account to map to a payer, all sampled negotiated contracts to reproduce expected charges, and every invoice difference to have a reviewed explanation. Those are more actionable than a general statement that results look close.
What can go wrong
An average error rate can hide a catastrophic individual invoice. Check account-level outliers, zero-priced usage and unusual rate transitions, not only mean accuracy across the migration.
Questions for your team
- Agree launch blockers and reviewers.
- Test representative and exceptional contracts.
- Inspect account-level differences.
- Record evidence and approved exceptions before launch.
Frequently asked questions
- Should we demand zero differences?
- Demand zero unexplained differences in the accepted scope. Intentional changes may create differences, but each needs a documented reason and approval.
