Shopify Checkout Not Working? 8 Fixes That Actually Work

Shopify checkout not working means zero sales. Every minute the issue persists costs you money. This guide covers the 8 most common checkout failures and exactly how to fix each one.

Fix 1: Check Payment Gateway Status

Before anything else, check if Shopify Payments, Stripe or PayPal are experiencing outages. Go to Settings → Payments in your Shopify admin. If your gateway shows an error or warning, that's your problem — it's a provider-side issue.

Also check the payment provider's status page. Shopify Payments outages are posted at shopifystatus.com.

Fix 2: Test in a Private/Incognito Window

Many checkout issues are browser-specific — cached data, a blocked extension, or a stale session token. Open a private/incognito window and try the full checkout from scratch with a test product.

If it works in incognito, clear your main browser cache and cookies. If it only fails in one browser, it's a browser compatibility issue with a script or app.

Fix 3: Disable Recently Installed Apps

Shopify apps often inject JavaScript into the checkout. A recently installed app may be conflicting with the payment process. Disable apps one by one (start with the most recently installed) and test checkout after each one.

Fix 4: Check SSL Certificate

Shopify checkout requires a valid SSL certificate. If your domain recently changed, SSL can take 24–48 hours to provision. Go to Settings → Domains and check if your SSL shows as active.

Some payment gateways (especially Stripe) will refuse connections over non-HTTPS or expired SSL.

Fix 5: Review Checkout Settings

In Settings → Checkout, check your customer account settings, email requirements and order processing settings. A mismatch between required fields and what your customer is providing can silently block checkout completion.

Fix 6: Check Shipping Rate Configuration

If customers can reach payment but the checkout won't proceed, often the issue is no shipping rates available for the customer's location. Go to Settings → Shipping and delivery and verify that shipping rates exist for the countries you're selling to.

Fix 7: Test with Shopify's Bogus Gateway

Enable the Bogus Gateway (Settings → Payments → Add payment method → Search "Bogus Gateway"). This lets you complete a real test transaction without charging anything. If Bogus Gateway works but your real gateway doesn't, the issue is with your payment provider configuration — API keys, webhook URLs or account verification.

Fix 8: Check Payment Provider API Keys

Your payment gateway API keys can expire or become invalid. In Shopify Payments, Stripe or PayPal, verify:

• API keys are current and haven't been rotated/revoked
• Webhook endpoints point to the correct Shopify URL
• Your payment account is fully verified (some accounts require identity verification)
• You're using live keys in production (not test keys)
