The store can fail in the middle of the path
A homepage uptime check never clicks “Add to cart.” A broken product form, a shipping-rate error, or a payment-gateway timeout can sit unnoticed until a customer writes in — or until revenue drops.
For Shopify stores
Your homepage can be up while checkout is broken.
Tillcheck would run your store’s add-to-cart and checkout path on a schedule — without placing a real order — and alert you if a step fails. Planned prices are US$19 and US$49 a month. This product is not launched; this page is a waitlist.
Built by a solo engineer, part-time. Not affiliated with or endorsed by Shopify. Tillcheck is a working name.

Alert: add-to-cart failed
The add-to-cart control returned an error after a theme publish three hours ago. Homepage still responded 200.
A green homepage is not a working checkout
Merchants and agencies already describe this: a theme or app change breaks add-to-cart or checkout, ads keep spending, and the storefront status page still looks fine. A few Shopify apps already sell this kind of check. This waitlist is to see whether a simpler, lower-priced version is something you would pay for.
Theme and app updates are a common trigger
The planned product would run after a theme publish, and on a regular schedule otherwise. We would not complete a real purchase, and we would not store a customer’s payment details.
Incumbents already exist
Shopify App Store listings such as Uptime (from US$29 / month) and Shoptest (from US$59 / month) already offer checkout-path monitoring, with a modest number of public reviews. We would not claim a bigger feature set than tools that have been live for years.
How it would work
A planned first version. This is the intended product, not a recording of a running app.
Connect a Shopify store
Install a small app (once it exists and passes Shopify’s review) or point us at a storefront URL for a limited first test. Permissions would be the minimum needed to run a checkout path. We would not take over your store.
We walk the path, and stop before payment
A headless browser opens a product, adds it to the cart, and proceeds toward checkout. It does not submit a real payment. If a step fails, the run stops and we keep a screenshot of that step.
You get an alert, not a weekly PDF
Email on the Starter plan; Slack, Telegram, or LINE are planned on Pro. If a theme was published just before the failure, the alert would mention that. The first version is a health check, not an AI testing platform.
Planned pricing
Prices we want to test — not a live charge. This page will not bill you. Listing on the Shopify App Store would come later, and only after payouts from Taiwan are confirmed; that registration fee has not been paid.

FAQ
Is this launched? Is there a Shopify app I can install?
No. This is an early-access waitlist. There is no App Store listing, no paying customers, and no checkout on this page. A US$19 Shopify Partner App Store registration has not been paid, and would not be paid until payouts to a Taiwan-based partner are confirmed in the Partner dashboard.
Will you place a real order on my store?
No. The planned run stops before payment. We would not ask for a customer’s card, and we would not complete a purchase to “test” the thank-you page in the first version.
How is this different from Shopify Uptime or Shoptest?
Those apps are already listed and already charge from US$29 and US$59 a month. Public review counts were modest when we looked (31 and 5 respectively, on 13 November 2026). We would try a simpler, cheaper check — not a broader AI testing suite. We do not have reviews of our own, and we are not asking you to switch based on claims we cannot back.
What about false alarms, or a test that itself breaks the cart?
A bad selector after a theme change can make a test fail, or (worse) a sloppy test could add junk to a cart. The first version would use a throwaway cart in a fresh session, avoid real payment, and treat false alarms as a product problem to fix. A solo early tool will get this wrong sometimes; we would rather say that than promise otherwise.
Who is building this, and how will you take payment?
A solo software engineer, part-time. If the product is listed on the Shopify App Store, billing would follow Shopify’s app billing, subject to confirming that a Taiwan-based partner can actually receive payouts. Outside the App Store, payment would go through a merchant-of-record such as Paddle, Lemon Squeezy, or Polar. None of those accounts has been opened for this product yet.
Is this affiliated with Shopify?
No. “Shopify” is used here only to describe the stores the tool would support. Tillcheck is not affiliated with, endorsed by, or a partner of Shopify at this time, and we will not claim Partner status unless that rank is official.
