Subscription learning app — instrumentation review
The team’s board pack showed weekly “purchases” 18% higher than finance settlements. Server Canvas Base traced the gap to a client event firing on payment sheet open. The review remapped three journeys (trial start, first paid period, renewal) onto handlers that write the entitlement table. Implementation took the client’s engineers nine days; the following month’s board pack matched settlement within normal chargeback variance.
Constraint worth noting: staging lacked realistic promo codes, so one property had to be validated in production with a feature flag and a short dual-write period.
