UX as a revenue variable
Every UX decision in an ecommerce store has a measurable revenue consequence. The position of the add-to-cart button on the product page. The number of fields in the checkout. The clarity of the size guide. The placement of the returns policy. These are not aesthetic decisions — they are commercial decisions that happen to be expressed through design.
Most ecommerce UX work fails because it treats these decisions as design problems rather than commercial ones. The result is a store that looks considered but has not been designed with the specific conversion logic of ecommerce in mind. Pretty layouts that do not surface the product clearly. Navigation that reflects the brand's internal organisation rather than the customer's mental model. Trust signals buried below the fold where they do not influence the purchase decision.
Wall & Fifth designs ecommerce interfaces with the commercial logic explicit at every decision point. What is this element doing? What does the customer need to see at this moment in the purchase journey? What would make them more likely to continue, and what would give them a reason to leave?
Discovery to product page
The journey from store arrival to product page has three primary failure modes. First: navigation that requires the customer to understand the brand's internal product taxonomy rather than browse in the way they naturally think about the category. A customer looking for "something to wear at a summer wedding" is not looking for "occasionwear > midi dresses > floral." They are browsing by occasion, mood, or occasion-specific need.
Second: collection pages that do not surface the right product to the right customer efficiently. Poor sorting defaults, filtering systems that require the customer to know the product range before they can use them, and grid layouts that give equal weight to every product regardless of its commercial importance.
Third: collection page imagery that does not differentiate between products quickly enough. If every product card looks similar, the customer has to click into each product to understand what it is. That friction accumulates across a browsing session and produces a lower click-to-product-page rate.
Product page architecture
The product page is where the purchase decision is made. Its architecture has to be designed around the specific sequence in which a customer evaluates a product — which is not the same sequence in which a designer finds it most visually interesting to present it.
The customer arrives at the product page with a set of questions they need to answer before they can commit: Is this actually what I want? What does it look like in real life? Will it fit? Is the quality worth the price? What do other people think? What happens if it is not right? Each of those questions has a corresponding design element — and those elements need to appear in the order the customer needs them, not the order that produces the most balanced layout.
We design product pages around that question sequence. Imagery that answers "is this actually what I want" immediately. Specification and sizing that answers "will it fit" before the customer has to search for it. Social proof positioned at the moment of maximum hesitation — not decoratively distributed across the page.
Cart and checkout
Cart and checkout abandonment is the most expensive UX failure in ecommerce — because it occurs at the highest-intent moment in the funnel. The customer has decided to buy; something in the checkout process has changed their mind. The causes are almost always the same: unexpected costs, required account creation, a multi-step process that feels disproportionate to the purchase, or a payment page that does not look trustworthy.
We design checkout flows that eliminate each of those failure modes: shipping costs surfaced before checkout, guest checkout as the default path, a single-page or minimal-step checkout architecture, and consistent brand treatment through to the payment step.
How we work
We audit the existing store's UX against the full purchase journey — from arrival to post-purchase confirmation — identifying the specific friction points that are producing drop-off. We produce a prioritised set of design improvements ordered by commercial impact, implement them, and measure the effect.

In ecommerce, the difference between a 2% and a 4% conversion rate is not a design quality difference. It is a friction difference. Find the friction. Remove it.
