Customers say checkout is down but it works for me, why?

Often device or region-specific: a failing express wallet, a browser extension conflict, or a payment method unavailable in their country.

Why are all cards being declined?

Gateway outage, verification hold on your account, or aggressive fraud settings. Check payment settings and the gateway status.

How long do checkout outages last?

Platform incidents are rare and usually resolved within hours; your own configuration issues persist until fixed.

Shopify Checkout Not Working: a Troubleshooting Path

When Shopify checkout fails, identify where it fails: buyers cannot reach checkout (cart or button issue), cannot complete payment (gateway or card issue), or orders fail silently (payment settings issue). Check the status page, test with your own card, review payment settings, and inspect recent app or theme changes before contacting support.

Define the failure precisely

Cannot proceed past the cart points to theme or app problems. Payment declined for all cards points to gateway configuration. Declined for some cards only is normal fraud filtering. Orders placing but confirmation emails missing is a notification issue, not a checkout issue. Each path has a different fix.

Check payments configuration

In Settings then Payments, confirm Shopify Payments (or your gateway) is active and fully verified, since incomplete verification can block processing. If you use a third-party gateway, test its credentials. A gateway that expired or hit its own fraud limits stops payments store-wide.

Test like a customer

Place a real test order with your own card and another method (PayPal or Shop Pay). Note the exact error text. Generic try-again errors with green status pages often mean a temporary processor issue; specific decline messages are usually legitimate card issues.

Recent changes again

New checkout app blocks, custom scripts, or a theme update can break the add-to-cart to checkout path. Disable recent checkout blocks in the editor and test again. If the failure started today, whatever changed today is the prime suspect.
