Checkout abandonment was 79% at a €1,400 average order value. The flow had been ported from a US template into a market where invoice payment is normal and delivery uncertainty is intolerable.

Rebuilt around German purchase norms - invoice payment first, delivery date committed before payment, returns terms stated in full at the point of decision.
Abandonment fell by more than a third. Nothing about the product, price or logistics changed; only the sequence and what was disclosed.

THE ARGUMENT
Why the obvious solution was wrong.
The study matters because the product problem was reframed before the interface was polished.
The checkout had been built for a market where a credit card is the default and a delivery estimate is acceptable. In DACH, Kauf auf Rechnung is a mainstream expectation rather than a niche option, and a €1,400 purchase with a two-week delivery window is not a purchase anyone completes. The abandonment was not friction in the usual sense. It was a sequence that asked for money before it had earned the conditions under which a German customer pays.
Invoice payment moved to first position rather than last. The delivery date became a committed date shown before the payment step, with the window narrowed by working the logistics constraint rather than hedging it in copy. Returns terms - who pays, how long, what condition - were stated in full on the payment screen rather than linked. Every change moved certainty earlier in the sequence. Abandonment fell by 28 points and support contacts fell nearly by half, because the questions people used to email about were answered before they paid.
THE INTERFACE CRAFT
The interaction, rendered as a working product surface.
The specimen below is code-native and uses the study's own design logic. The client interface remains protected.

DESIGN DECISIONS
Positions we would defend.
Each decision names the principle and the product consequence, not a stylistic preference.
Localise the sequence, not the strings
A translated checkout in the wrong order is still the wrong checkout. Payment norms are structural, not copy.
Commit to a date
A delivery window is a hedge the customer reads as uncertainty. Narrowing it required a logistics conversation, not a design one.
Disclose before payment
Every question answered after payment is a support contact and a return. Move them all in front of the money.
PRODUCT LEADER READOUT
What transfers, and what should remain specific to this product.
A case study is useful when its operating principle travels without turning the original interface into a template.
Read the operating condition
For Furniture D2C · DACH · €1,400 AOV, the transferable lesson is not a copied screen. It is the condition the interface had to make legible: Kauf auf Rechnung presented as the primary method rather than buried below card options ported from a US template. Rebuild that visibility for your own roles, risk, terminology, and operating cadence.
Protect the design rule
A translated checkout in the wrong order is still the wrong checkout. Payment norms are structural, not copy. Keep that rule in the acceptance criteria, component states, and production QA record so later visual cleanup cannot erase why the interaction exists.
Measure behaviour after ship
The evidence record is 51% for checkout abandonment, from 79%. Recreate the baseline and outcome window before rollout, segment the result by role and context, and state clearly what the measure cannot prove.
RESEARCH RECORD
The work behind the interface.
These artefacts connect the final interaction back to the evidence and product model that produced it.
Abandonment session replay
Reviewed 120 abandoned checkouts; 61% abandoned within four seconds of the payment-method screen.
DACH purchase norm research
Interviewed 18 German consumers on high-value online purchase behaviour and payment expectation.
Delivery commitment feasibility
Worked with the logistics team to establish which date could be honestly committed at 96% reliability.
Returns comprehension test
Tested full disclosure against linked terms for both comprehension and completion; disclosure won on both.
“We had translated the checkout. We had not localised it. Those are different projects.”
