Checkout monitoring that clicks the buttons a shopper clicks
A checkout monitor opens a product page in a real browser, clicks add to cart, confirms the cart appears, then clicks through and confirms the checkout page opens. It runs on the schedule you set. When a step does not produce what it should, you get a screenshot of the page and a plain-English summary.

What happened
Clicking Checkout returned an error instead of the checkout page. Shoppers who get as far as the cart cannot go any further.

What does a checkout monitor actually check?
It performs the journey rather than requesting the page. A check navigates to the URL you give it, clicks the element you picked, waits for the page to settle, and then asserts that something specific is true: that the cart region exists, that the page title changed, that the URL now matches your checkout path, or that a particular piece of text is present.
That assertion is the point. A page returning a normal response while the cart stays empty fails the assertion, which is exactly the failure an uptime tool reports as healthy.
What does it not do?
It does not sign in, and it does not place an order. There is nowhere to store credentials or card details, and a region that looks like a password or payment field is flagged for review rather than blocked. A checkout monitor proves a shopper can reach checkout; it does not prove a card will be charged.
If that distinction matters for your store, the honest framing is that this catches the breakages that happen most often and cost the most: a dead button, a cart that stops rendering, a checkout link that starts erroring after a theme or plugin update.
Which monitors should a store set up first?
| Monitor | What it confirms | Why it matters |
|---|---|---|
| Add to cart | Clicking add to cart makes the cart appear | The single most common silent breakage after a theme change |
| Checkout opens | Clicking through from the cart lands on your checkout URL | Catches a broken checkout link before a shopper meets it |
| Cart page ready | The cart page renders its contents | Catches an empty or erroring cart template |
| Product page | The page loads and shows the price and buy button | Catches a broken product template or a missing price |
Four monitors on one store fit inside every paid plan.
How quickly will you hear about it?
As fast as the interval you set, and how fast you can set it depends on your plan. The table below shows the fastest interval each plan allows. A failure sends an email straight away, and a recovery sends a second one, so you know when it clears without checking.

Frequently asked questions
Can it test a real purchase end to end?
No. Checks confirm the journey reaches your checkout page. They do not enter card details and do not complete an order.
Will it work on my platform?
If the page is reachable in a browser, yes. Monitors work against the rendered page rather than a platform API, so the underlying store software does not matter. Simrix Monitor recognises common platforms and suggests templates that suit them.
Does it need anything installed on my store?
No. There is no app, plugin, script or tag to add. You give it a URL and it drives a browser from the outside, exactly as a shopper would.
What do I get when a checkout monitor fails?
An email with a screenshot of the page at the moment it failed and a plain-English summary of what went wrong. Opening the check shows the journey it ran, how far it got, the final URL, the response code and the duration.
How long are screenshots kept?
Seven days. The record of every check is kept, so the history of passes and failures stays, but the images behind older checks are removed.
