Checkout Friction
Checkout friction is the effort or obstacles that make completing a purchase difficult during identification, delivery, review and payment. It applies the broader UX concept of friction to order completion.
What it means
The difficulty may involve understanding an instruction, repeating information or recovering from an error. Screen and click counts alone cannot measure it. An additional review may prevent an incorrect purchase; a short step can still demand substantial work when requirements are ambiguous.
Origin of the concept
The term is used in ecommerce task analysis and usability. Baymard’s checkout research examines forms and interaction effort. Findings can inform design questions rather than automatically attributing a conversion improvement to every removed field.
Application in UX
Explain formats beside the relevant field, retain values after errors and provide actionable recovery messages. Validation should not leave someone wondering what changed or how to continue. Check keyboard interaction, mobile devices and available input assistance.
Application in ecommerce
Display the final amount and delivery conditions before confirmation. Distinguish information required to fulfil an order from optional preferences. When several payment methods exist, explain availability and avoid requesting details needed only for an alternative that has not yet been selected.
Practical example
Imagine an address error that empties the entire form. Retaining information and identifying the field needing attention would remove avoidable repetition. Observe corrections and task completion; this example is neither a completed experiment nor a demonstrated commercial result.
Common mistakes
Do not remove useful confirmations merely to reduce steps. Avoid forcing extras before progression or assuming every exit means a broken form: someone may reconsider the purchase. Investigate specific obstacles and commercial conditions before proposing changes.
