Access
Read-only property access, warehouse replica and the current tracking spec. Named analysts only.
We test the pipe between your product and your dashboard: tracking plans, event payloads, segments, joins 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 without a call.
| Workstream | What it covers | Deliverable | Window | From |
|---|---|---|---|---|
| Tracking plan audit | Gap analysis across product, marketing and billing events; duplicates, dead events and naming drift called out | Prioritised fix list | 5 working days | £2,800 |
| Event verification | Live checks that fired events match spec, with payload samples and timestamp evidence | Evidence log | per release | £1,400 |
| Dashboard reconciliation | Counts, filters, segments and joins tested against source tables, including shared-board drilldowns | Reconciliation note | 3“5 days | £2,200 |
| Consent and tagging review | Consent-mode behaviour, pre-tick firing and third-party tags measured against your own policy | Findings memo | 4 days | £1,900 |
| Field and device capture | Real hardware passes by paid testers where emulators under-report behaviour | Session records | scheduled | £1,600 / 50 |
| Retest | Verification against the same evidence tree after fixes | Closure note | 14 days | included |
A retail client, October. Two of these had been quoted upward for two quarters.
| Billing event fires twice on retry | P-02 | high |
| Segment drops returning users after cache warm | P-05 | high |
| Campaign UTM stripped on redirect | P-08 | medium |
| Consent flag read before default applied | P-11 | medium |
| Duplicate purchase event across two properties | P-14 | fixed |
Predictable, read-only, and closed with a retest. Nobody from the practice writes into your production properties.
Read-only property access, warehouse replica and the current tracking spec. Named analysts only.
Spec against reality, event by event. Payloads sampled live with timestamps and screenshots.
Findings ordered by the size of the decision each distorts, from billing down to housekeeping.
Fixes verified in the 14-day window, closure note issued, access revoked the same day.
Coverage across the common commercial stacks and plain warehouse SQL. Where a stack is in beta, we say so before quoting.
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.
No. Read-only analytics access and a warehouse replica are enough. If a check needs a live transaction, we use a sandbox and say so in the scope.
We will look at it in week one and tell you whether we can audit it properly. If not, the workstream is removed from the quote rather than fudged.
In a structured folder keyed to finding IDs, shared read-only with you, retained 24 months, then deleted with a written confirmation.
Rarely. Auditing your own implementation is a weaker position, so we keep the two apart unless you ask us to cover a specific gap.
Name the property, the decision and the deadline. Reply within one working day, scope attached.
