Checkout is one of the most measured, and most overlooked, parts of ecommerce.
Small UX mistakes at checkout can quietly destroy conversion rates, especially on mobile. Below are 10 common checkout UX mistakes and how to fix them.
1. Too Many Form Fields
Every extra field increases abandonment.
Fix: Remove non-essential fields and rely on autofill where possible.
2. Unclear Free Shipping Thresholds
Customers often leave checkout to find shipping details.
Fix: Clearly surface free shipping thresholds at checkout.
3. Irrelevant Upsells
Generic upsells feel like interruptions.
Fix: Only show upsells that logically match the cart and customer segment.
4. No Reinforcement of Value
Customers hesitate at the final step.
Fix: Reinforce returns, delivery speed, or guarantees at checkout.
5. Poor Mobile Layout
Most checkouts happen on mobile.
Fix: Optimise spacing, tap targets, and content hierarchy.
6. Hidden Fees
Unexpected costs cause immediate abandonment.
Fix: Be transparent early and consistently.
7. Slow Checkout Load Times
Checkout speed directly impacts conversion.
Fix: Use lightweight components and performance-friendly tools.
8. No Personalisation
Treating all customers the same wastes opportunity.
Fix: Personalise content by cart, customer segment, or market.
9. Missing Trust Signals
Customers need reassurance before paying.
Fix: Add trust badges, reviews, or delivery assurances.
10. Treating Checkout as “Set and Forget”
Checkout performance changes over time.
Fix: Review, test, and optimise regularly.
