When revenue is computed rather than agreed, a quiet defect in charge logic is a quiet defect in revenue. The uncomfortable part is that nobody will say a number out loud. Being wrong about revenue in front of finance is career-damaging, so the estimate stays vague and the problem stays funded at zero.
Read-only. Measurement and mutation are separate engagements.
Usage-metered SaaS, per-shipment and per-transaction platforms, marketplaces taking a rate: anyone whose invoice is the output of code rather than of a contract line item. Typically post-product-market-fit, 10–60 engineers, and a finance function that has learned not to fully trust the number.
Where charge behaviour is defined, how many implementations exist, and where they disagree, with the exposure quantified and dated rather than characterised.
What was under- or over-billed, for which period, on what evidence. A figure you can take to finance with its working attached.
Consolidation to one implementation, with a test suite that pins current behaviour first so the consolidation is provably behaviour-preserving before it is an improvement.
Retained, so the next drift is caught by a check rather than by a customer.
On a billing programme of ours, a recurring leak originated in our own earlier change. We disclosed it in writing, with the figure, while the fix was still in review. A billing review that only ever finds other people’s mistakes is a sales document.
A remediation names the exact affected rows and reprices exactly those. A bulk re-run is how a billing fix becomes a billing incident.
Never smoothed, never rounded into a story. If the reconciliation has a residual we cannot account for, that residual is in the report.
So you know what the number was true of, and when. Recalibration is a scheduled task rather than an assumption.
How many places would a change to how you charge have to be made? If the honest answer is that nobody knows, that is the finding, and it is what the assessment turns into a number.

Our fit rating for this market is Shipped, from the capability register we maintain internally. No client is named anywhere on this site. Figures from engagement work are quoted only with their measurement basis and date, and only where they sit on our internal claims register. Ask and we will show you the working. We publish no improvement or recovery percentage we have not measured.
