An emptied cart is one of the most frustrating checkout failures because the site can look healthy until the buyer reaches the critical step. Cache configuration, cookies, session handling, Store API behavior or plugin conflicts can all produce the same visible symptom: the cart disappears before payment.
CashFlowCanary monitors the funnel without storing customer cart contents. It focuses on synthetic evidence: whether the cart state survives long enough to reach checkout, whether the checkout page behaves as expected, and whether the failure is repeatable.
The broader monitoring model is explained in features. The right plan depends on how many pages and stores must be watched, so compare plans. For a first diagnosis, ask for a free audit.
When a cart empties, the team needs proof before changing cache, cookie or checkout settings. A clear signal avoids guessing and helps decide whether the issue belongs to hosting, theme code, WooCommerce configuration or a payment/plugin interaction.
