Ecommerce Checkout Optimisation: Reducing Cart and Checkout Abandonment

Checkout is where ecommerce stores lose a large share of potential sales. Shoppers add items to their cart, start checkout, then leave. Some were only browsing, but many abandon because of avoidable friction: unexpected costs, forced account creation, long forms, limited payment options or doubts about security. Research from the Baymard Institute, which has studied checkout usability for many years, consistently finds that a significant share of abandonments relate to fixable design and process issues.

Common reasons shoppers abandon checkout

• Unexpected extra costs: shipping, taxes or fees revealed late.
• Forced account creation.
• Long or complicated forms.
• Delivery too slow or unclear.
• Concerns about payment security.
• Limited payment methods.
• Unclear returns policy.
• Errors and validation problems.
• Slow loading or technical issues.

Show total costs early

Display shipping costs or thresholds on product pages and in the cart, not only at the final step. A shipping calculator or clear shipping table helps. Surprises at checkout are a leading cause of abandonment.

Offer guest checkout

Let shoppers buy without creating an account. Offer account creation after purchase, when it can be done with a single click using the details already entered.

Simplify forms

• Ask only for necessary information.
• Use address lookup or autocomplete.
• Default billing address to the shipping address.
• Use correct input types for mobile keyboards.
• Combine name fields where practical.
• Show clear, inline error messages.

Our guide to microcopy covers labels and error messages.

Offer preferred payment methods

Express wallets such as Apple Pay, Google Pay, Shop Pay and PayPal speed up checkout, especially on mobile. Buy-now-pay-later options can help for higher-priced items in some markets. Offer the methods your customers actually use.

Reinforce trust

Show recognised payment logos, secure checkout indicators, returns and refund information, and customer support contact options. Keep the design consistent with the rest of the store so checkout does not feel like a different site. See our guide on website trust signals.

Show progress and order summary

For multi-step checkouts, a progress indicator shows how much remains. Keep an order summary with product images, quantities and totals visible.

Make delivery clear

Show delivery options with estimated dates, not just methods. Specific dates are more reassuring than “3 to 5 business days”.

Reduce distractions

Many stores simplify navigation during checkout to keep focus on completing the purchase. Avoid adding upsells that interrupt payment steps; place them in the cart or post-purchase instead.

Optimise for mobile and speed

Test checkout on real phones. Large tap targets, readable text and fast loading matter. Remove unnecessary scripts from checkout pages where your platform allows. See our guide on third-party scripts.

Platform considerations

Shopify: checkout is highly optimised and standardised; customisation options depend on plan. Focus on settings such as guest checkout, payment options, shipping clarity and checkout branding. See our Shopify store mistakes guide.

WooCommerce: checkout is highly customisable, which means more room for both improvement and problems. Block-based checkout and well-maintained payment plugins help.

Recover abandoned checkouts

Abandoned checkout emails, sent with consent where required, can recover a portion of lost sales. Keep them helpful: remind shoppers of their items, address common concerns and link straight back to checkout.

Measure and test

Track the funnel in analytics: cart, begin checkout, shipping, payment and purchase. Identify the step with the largest drop. Session recordings show where shoppers hesitate or encounter errors. Test changes one at a time and compare conversion rates. See our guide to GA4 conversion tracking.

Turning carts into orders

Checkout improvements often produce some of the fastest revenue gains in ecommerce, because they help shoppers who have already decided to buy.

If your store loses too many shoppers at checkout, our ecommerce web development service can audit the funnel and implement fixes on Shopify or WooCommerce.
