Checkout UX: 7 mistakes that lose certain orders

Checkout is where 30-50% of users who already added products to cart abandon. They're already qualified with strong intent. Recovering them is the highest-ROI CRO. Here are the 7 most expensive mistakes.

1. Forcing registration

"Create account to continue" = -35% conversion. Solution: optional guest checkout, account creatable after. Abandonment reduction: -25%.

2. Too many steps without progress bar

4-5 steps without showing "step 2/4" makes flow feel infinite. Add visible progress bar. Conversion +12%.

3. Shipping costs shown only at last step

User builds cart thinking €50, discovers €58 at checkout. Guaranteed abandonment. Solution: show estimated costs in mini-cart.

4. Limited payment methods

Credit card only = -20% mobile conversion. Add PayPal, Apple Pay, Google Pay, Klarna/Scalapay. See payments guide.

5. Form that doesn't remember data

Accidental refresh = all lost = abandonment. Implement autocomplete and localStorage save. Post-error abandonment reduction: -40%.

6. No trust signals at checkout

SSL badge, "secure payment" badge, visible phone number, VAT. Look like details, but at checkout converge +5-9%.

7. Poor mobile UX

65% of checkouts are mobile in 2026. Critical mobile errors: small buttons, iOS autoZoom, wrong keyboard, password type for CVV. Real iPhone test mandatory.

Combined, these 7 fixes bring +35-60% checkout conversion without changing traffic. Implemented in the Commerce package €4,990.
