Shopify Checkout Error: A Checkout That Lets the Order Through
A checkout error is the most expensive fault a store can have, because the shopper has already decided to buy. Because checkout is hosted by Shopify, the cause is nearly always a setting or an app, and a test order is the way to find it.
Orders that stop at the last step
Shoppers see an error, no shipping option, a declined payment message or a page that will not advance. Some give up and you may never hear about it.
A checkout that completes
The cause is traced by test orders and fixed in your settings or apps. Checkout is retested on phone and desktop, in your selling countries and with your payment methods.
What Your Checkout Fix Includes
When you fix checkout errors, you get the test orders, the diagnosis and the retest.
Implementation checklist
- The error reproduced with test orders in the situations it occurs
- Shipping rates and zones checked against the addresses that fail
- Payment methods checked for each country and currency
- Products checked for stock, weight and shipping settings
- Discount, market and domain settings reviewed
- Apps and scripts that touch checkout identified
- The fix made in the setting or app that causes it
- A plain note of the cause and how to avoid it
Checkout is hosted and controlled by Shopify, so we fix settings and apps and cannot edit checkout code on most plans. An error from Shopify's own platform incident is not the store's to fix, and we say so if that is the cause.
From an Error at the Last Step to an Order That Completes
Follow one diagnosis. We reproduce the error with test orders, trace the setting or app behind it, fix it and retest each path.
