## What you need to know

### Which events should be verified?

Check cart view, checkout start, address completion, shipping selection, payment attempt, payment outcome and confirmed purchase. Each event must fire exactly once for the intended action.

### How are step rates calculated?

Checkout completion compares confirmed orders with checkout starts for a defined period and cohort. Keep the denominator and timing consistent when breaking results down by phone, laptop, guest or account.

### Can method breakdowns mislead?

A payment method may be available only in one country or on one device. Compare the same eligible shoppers and inspect error logs before deciding one provider is worse.

### A quick store check

Run one successful and one failed payment. Compare the event record with the order system and remove duplicate or missing events.

Reconcile analytics with actual order and payment records. Do not treat a broken confirmation page as proof that the sale did not happen.

### Where do I configure checkout tracking?

Use current analytics guidance and reconcile test events with actual orders before relying on funnel reports.
