A WooCommerce checkout can be broken while the checkout URL still returns a normal page. The form may not submit, the payment method may disappear, the Store API may fail, or the final confirmation may never appear. From the outside, the store is online; from the buyer's path, it is not converting.
CashFlowCanary watches the checkout path as a business-critical sequence. It separates page availability from conversion behavior, records the affected step and turns the issue into a prioritized incident with evidence the team can use.
The service scope is described in features, including monitored pages and incident proof. You can compare cadence, monitors and reporting in plans. To validate a first site, request a free audit.
The useful question is not "does the checkout page load?" It is "can a buyer still move through cart, checkout, payment and confirmation?" Monitoring should answer that question before customers start reporting the failure.
