Gumroad checkout page: where buyers stop

Sellers usually test their checkout in their own browser, signed in, on the product page they built. Buyers arrive by other routes: a link posted in a social app, a buy button embedded on a blog, or a product page opened on a phone. Each route changes what the buyer sees. An in-app browser may block the checkout overlay, a blocker may stop the payment fields from loading, and a pay-what-you-want price may stay empty until the buyer types an amount. The seller sees a working checkout, and the buyer sees a button that does nothing.

• Open the product link from inside a social app, then press Buy, and note whether checkout opens at all.
• Check that a version, size or price is chosen before Buy, and that a pay-what-you-want amount is filled in.
• Open the checkout on a phone and look for the payment fields, including any wallet button the page shows.
• Compare the total on the checkout with the price on the product page, and note any tax line that appears.
• If you embed the buy button, check the console at the click for a blocked script or a refused frame.

A buyer lands on the product page and looks for three things: the price, the version they want, and a button that says Buy. Products can carry options such as a size, a tier or a pay-what-you-want amount, and a buyer who presses Buy before choosing one may see the total change or a prompt they missed. Read the page as a buyer who has never seen the product. If the version choice sits below the fold on a phone, the buyer may pick the wrong one or give up before they find it.

Check the product page in a private window with no saved details, the state a buyer arrives in. Note every point where the price changes, from the product page to the checkout total, and any pay-what-you-want amount that has to be typed before Buy does anything. Do this on a phone as well as a laptop, since a version picker that sits low on a phone is where a buyer hesitates first.

When a buy button sits on your own site, the checkout may open in an overlay on that page. That depends on a script loading and a frame opening on top of the page. A pop-up blocker, a cookie banner or a strict security setting can stop either one, and the buyer sees a button that does nothing. This is a different fault from a broken product page. The product looks right, and the failure happens only at the click.

In-app browsers are the common trap. A link opened from inside a social app runs in that app's own browser, which may block scripts or frames that a normal browser allows. A seller testing in a desktop browser never sees that. Test the link from inside the app once, then decide whether that traffic should go to a plain product link instead.

A simulated visitor opens the product link in a real browser, chooses the version and price, enters the details the checkout asks for, and goes on until the payment step. The run reports the screen where it stopped, a screenshot, and any script error or failed request recorded there. A payment field that never loads shows up as the step where the run stopped, with the error beside it.

It stops there by design. Visitors cannot pay with a real card, and the run never completes a purchase. If the payment step is the question, check it with your payment provider's own test tools, not with this run. Treat it as a separate check. The run also does not read your sales, so it cannot say whether buyers who reached that step finished.

Products get new tiers, prices and embeds after launch, and each change can move the buy button or add a field the buyer must fill in. A new version, a coupon or an updated embed on your site can change the path. After each change, run the same link from a phone through to the payment step, and check the overlay opens. The second run catches the break before a new campaign sends buyers to it.
