Cart QA: 6 Checks to Stop Silent Drop-offs
Run through the six test scenarios that catch payment errors, broken upsells, and shipping issues before launch.
Written by Boris — Lead Growth Strategist. We pressure-test every playbook before we share it with the community.
Most Shopify teams only test happy paths during a launch. We run through six QA flows that catch the silent drop-offs before conversion tanks.
- Guest checkout on mobile Safari with autofill
- Coupon application on the final step
- Express pay wallets (Shop Pay, Apple Pay, PayPal)
- Shipping method swap from free to paid tiers
- Cross-sell modal acceptance and dismissal
- Failed payment recovery messaging
Log every failure with screenshots and console output. Over time you will see patterns in specific apps or browser versions.
