A botched GA4 setup quietly corrupts every marketing decision that reads from it, for as long as it goes uncaught. This is plumbing — and plumbing failures don’t announce themselves; they flood everything downstream while the dashboard keeps confidently displaying numbers that are simply wrong.
Why It’s High-Stakes
Most migrations we audit have at least one of three failures: broken or duplicated events, conversion definitions that don’t match what the business actually counts, or attribution that doesn’t reconcile with the store’s own order data. Every dashboard, every optimisation, and every budget decision built on top of that inherits the error and amplifies it. The cost isn’t the migration itself — it’s the months of decisions made on corrupted data before anyone realises the foundation was never solid.
What We Do
An event and conversion model defined deliberately to match what finance counts as revenue and cost, not the platform defaults that quietly diverge from reality.
End-to-end QA against the store’s source-of-truth data so the numbers are demonstrably trustworthy before anyone is allowed to make decisions on them.
Historical context preserved and bridged so trend lines don’t snap on migration day and leave you blind to year-over-year performance.
