Checkout incomplete warning/suspension
What causes the "Checkout incomplete" warning or suspension in Merchant Center and how to fix it.
This means Google's automated checks found that customers can't actually complete a purchase on your site, often an error at the payment step. Fix it by testing the full checkout flow yourself end to end and fixing whatever blocks a real purchase before requesting review.
What triggers it
A "Checkout incomplete" warning or suspension means Google's automated checks tried to complete a purchase on your site and couldn't, an error at the payment step, a broken redirect, a form that fails to submit, or a plugin conflict that only shows up partway through checkout. Google treats a broken checkout as a serious trust problem: if shoppers can't actually buy what your feed advertises, the ads shouldn't run, similar in spirit to the checks behind misrepresentation and account suspension.
The tricky part is that a checkout bug can be intermittent or path-specific (only on mobile, only with one payment method), so a quick glance often misses it. A full, deliberate end-to-end test is the only reliable way to find it.
How /tools helps
Checkout itself sits outside the product feed, but /tools' feed and trust-signal monitoring covers the surrounding signals Google checks alongside it, so a checkout issue doesn't compound with an unrelated feed problem while you're fixing it.
Step by step
- Run a real test purchase yourself. Add a product to your basket and go through checkout exactly as a customer would, including entering real payment details on a low-value item if you can, rather than stopping partway.
- Test across devices and payment methods. Try mobile and desktop, and any payment options you offer (card, PayPal, buy-now-pay-later), since a broken checkout often only affects one path.
- Fix whatever blocks completion. Common causes are a broken payment gateway integration, an app or plugin conflict, a redirect loop, or a required field that silently fails validation.
- Re-test until a purchase completes cleanly. Confirm the full flow works end to end, ideally more than once, before requesting a review.
- Request review only once you're confident. Google will re-check the checkout flow itself, so don't request review until you've verified it works, not just assumed the fix landed.
