From click to CRM: attribution handoff without fiction

Attribution often breaks after the landing page. UTMs exist in the browser, but the backend creates the contact without source data. Or the CRM overwrites first-touch fields with the latest campaign. Or signup happens on another domain and the session disappears.

A clean handoff

Capture first-touch and latest-touch fields, store click IDs where legally appropriate, preserve source values, and connect anonymous visitor, signup and customer with a stable identity key.

The best attribution system is not the most complex model. It is the one that survives the real user journey.
