GA4 misses purchases when ad blockers, browser privacy settings or closed tabs stop the tag, and it never sees in-app checkouts in AI assistants or social apps. GapFill compares your orders with GA4 and shows what's missing by channel, source/medium and payment method. Orders still missing after 26 hours are sent to your GA4 property via the Measurement Protocol, with the GA4 client ID kept at checkout. Recurring orders, refunds and cancellations are optional. Nothing is sent until you approve.

• Report of orders missing from GA4, by channel, source/medium and payment method
• Sends only orders GA4 didn't track, matched by transaction ID
• Covers in-app checkouts in AI assistants and social apps, with their source
• Optional: recurring orders, refunds, cancellations and other channels
• Nothing sent until you approve, consent handling, auto-stop if IDs stop matching
