Checkout not working? Common causes and how to detect them

Checkout can fail while the rest of the store looks healthy. Learn what to test and how to catch failures early.

Common checkout failure modes

For common checkout failure modes, focus on the customer-facing result first. Build a repeatable check, keep the test safe, and record enough evidence to tell the difference between a short-lived warning and a real business-impacting failure.

Browser-based checkout testing

For browser-based checkout testing, focus on the customer-facing result first. Build a repeatable check, keep the test safe, and record enough evidence to tell the difference between a short-lived warning and a real business-impacting failure.

Safe stopping points

For safe stopping points, focus on the customer-facing result first. Build a repeatable check, keep the test safe, and record enough evidence to tell the difference between a short-lived warning and a real business-impacting failure.

What evidence to keep

For what evidence to keep, focus on the customer-facing result first. Build a repeatable check, keep the test safe, and record enough evidence to tell the difference between a short-lived warning and a real business-impacting failure.

A practical monitoring rule

If the failure would cost a lead, booking or order, monitor the complete customer action rather than only the page or server behind it.
