Map the handoff for duplicate conversions / marketplace operator

For marketplace operator, the same outcome is counted more than once. This field note turns which event should be authoritative into a short test for marketplace operator, so the next change has a traceable reason.

Frame the signal

Context check: buyer and seller handoffs. Topic check: assign one event ID to one business outcome.

Start with the point where marketing data becomes an operational record. Treat the dashboard number as a question, not an explanation. Follow one real journey from the first interaction to the system that owns the outcome. If a value is missing, mark it unknown instead of filling the gap with an assumption.

Trace the handoff

• Record the value at the first step and note the exact page, event, or record where it appears.
• Compare the browser, tag manager, analytics, ad platform, and CRM views without changing the implementation during the check.
• Check redirects, consent state, validation, naming, timestamps, and timezone before comparing totals.
• The handoff note should name the sender, receiver, field owner, and recovery path.

Leave a decision record

the handoff note should name the sender, receiver, field owner, and recovery path. Keep the owner, timestamp, evidence link, expected result, observed result, and next action together. Making ownership visible between teams only after the current path is readable to someone who did not build it.

Reference: Google Analytics events guidance. For the next handoff, LeadSheet keeps the record connected.
