An online store can answer every uptime check and still stop selling. The homepage returns HTTP 200, the product page loads, and the cart icon is visible, but customers may be blocked at cart update, payment selection or final confirmation.
That is why checkout monitoring must look beyond availability. CashFlowCanary follows the steps that create revenue and raises a signal when the funnel stops behaving like a buyer path. The goal is to catch the commercial failure before it becomes a hidden day of lost orders.
You can start with the public feature overview to see what is monitored, then compare the plans by cadence and reporting needs. If you want to check one store before committing, request a free audit.
The important distinction is simple: uptime tells you that a server responds. Checkout monitoring tells you whether the path that creates orders is still usable.
