The Checkout Autopsy: 12 Friction Points Costing You 20% Revenue

A field-tested audit checklist we run before every ecommerce engagement.

Jun 2026·6 min read·HS Nexus Senior Team

Checkout is where intent goes to die quietly. The failures are rarely dramatic; they are small hesitations that accumulate into abandonment, and almost all of them are visible in a careful walkthrough on a mid-range phone with a slow connection.

01The recurring twelve

These issues appear in the majority of audits we run:

  • Total cost, including shipping and tax, revealed only at the final step
  • Forced account creation before payment
  • Address forms that reject valid international formats
  • No visible progress indicator across steps
  • Payment methods the market actually prefers are missing
  • Discount field that draws attention away from completion
  • Errors reported after submission instead of inline
  • Slow third-party scripts blocking the payment button
  • No order summary visible while entering payment details
  • Trust signals absent at the moment of payment
  • Mobile keyboards that do not match the field type
  • No recovery path after a declined card

02Fix order matters

Sequence by expected revenue impact divided by build effort. Cost transparency and inline validation usually top that list; visual polish rarely does.

Re-run the walkthrough after each release. Checkout regressions ship silently more often than any other part of a storefront.
