Asking for Payment Before Address in Checkout

Asking for a payment method earlier may help some shoppers continue, but it may be impractical if the total or address-dependent options are not yet known.

  • Order completion rate

Hypothesis

Compare order completion alongside payment errors.

How to run this test

Primary metric

Order completion rate

Compare completed orders among visitors who start checkout.

Other metrics

  • Step abandonment rateReview abandonment by step to see whether it falls or shifts elsewhere.
  • Payment error rateTrack errors caused by payment-method incompatibility.
  • Revenue per visitor (RPV)Make sure revenue per visitor does not fall.
  • Support contactsTrack contacts such as reports that the total amount was not visible.

What to check before and during the test

  • Step orderMove the payment step earlier and compare order completion.
  • Total amountShow the total, including shipping, before requesting payment details. Do not use this setup if the total cannot be calculated without an address.
  • ConfidenceTrack abandonment and errors at the earlier payment step; use direct feedback to understand any hesitation.
  • Method compatibilityCheck whether payment methods that depend on the address still work in this order.
  • DeviceReview whether the step-order change has a different result on mobile.

Setup mistakes to avoid

  1. 1Do not wait until after payment details to show the total; keep pricing visible.
  2. 2Do not change step order and step count together.
  3. 3Keep payment security checks out of scope for this sequence test.
  4. 4Verify address-dependent payment methods technically before enabling the variant.
  5. 5Do not call a winner from completion alone without checking payment errors.
