We check the pipe between your product and your dashboard: tracking plans, event payloads, segments, filters and consent behaviour. If a figure cannot be reproduced from source data, we find out before it reaches a board slide.
Fixed-scope engagements, priced per deliverable. Every line ends in a document your engineers can act on.
| Workstream | What it covers | Deliverable | Window |
|---|---|---|---|
| Tracking plan audit | Gap analysis across product, marketing and billing events; duplicates and dead events called out | Prioritised fix list | 5 working days |
| Event verification | Live checks that fired events match spec, with payload samples and timestamp evidence | Evidence log | per release |
| Dashboard QA | Counts, filters, segments and joins tested against source tables | Reconciliation note | 3–5 days |
| Consent and tagging review | Consent-mode behaviour, pre-tick firing and third-party tags measured against your policy | Findings memo | 4 days |
| Field and device capture | Real hardware passes by paid testers where emulators under-report behaviour | Session records | scheduled |
Teams close to a launch stop seeing their own instrumentation. Three of the last five audits found a billing event that fired twice on retry — a figure that had been quoted upwards for two quarters.
Some checks need a real device, a real network and a real person. Those runs are briefed in writing, capped at twenty minutes and paid per accepted session.
