Data, reconciliation & reportingClient work
I define what each product event means, where it comes from, who owns it and how your team proves it matches a real business action.
Sounds familiar?
How I solve it
I build a measurement plan your team can implement and review. It starts with business questions, then defines the events that can answer them. Each entry records its source of truth, trigger, payload, identity, destinations and acceptance checks. I include versioning and ownership so the plan can survive the next product release.
The process
6 steps. Scope and a fixed price are agreed before the first one.
Agree the decisions the team needs to make and the records that can support them.
Inventory existing events and resolve conflicting definitions.
Define names, triggers, required fields and the owner of each business action.
Specify duplicate handling, consent behaviour and identity gaps.
Give the developer synthetic payloads and tests for success, failure and retries.
Agree the rollout, QA responsibilities and how later changes are reviewed.

Before → after
For the marketplace, conflicting event counts became canonical event and backend-truth contracts, with versioned changes and rollback. The specification covered more than the accepted implementation: offers were not deployed and purchase instrumentation had not started. The SaaS backing is an audit, with no completed revenue pipeline implied.

measurement audit. This backs the diagnosis and planning work; a completed SaaS revenue pipeline is not claimed.
What you can look at
The marketplace event-contract case shows why event identity and backend truth need a shared contract. The proposed handover for your team is a synthetic event dictionary and QA matrix, with a created account, a failed submission and a repeated callback shown separately.
Anonymised backing includes an event-contract engagement and a SaaS audit. Audit findings, specification and accepted implementation are distinct deliverables.
Price and timeline
A Tracking Health Check is USD 395 for one agreed measurement problem. A wider contract and implementation can be a Custom Engineering Project from USD 1,500. I quote the planning, implementation and QA scope explicitly so an approved dictionary is not mistaken for a deployed system.

A note from Daniilbefore you decide
If your team already has shared definitions, named owners and repeatable acceptance tests, extend the existing plan. If the only problem is one broken event, a bounded fix may be enough.

Questions
Names are one part. Each event also needs a business definition, a producer, fields, identity rules, consent behaviour, a destination and a test.
Only if implementation is in the agreed scope. A plan can be handed to your developer, with QA and rollout quoted separately.
