The flow sells, not the styling
The most common misconception we meet is that conversion is a design problem. It rarely is. Somebody who abandons a basket almost never leaves because they disliked a colour. They leave because something blocked them on the way to paying.
A shipping charge appearing as a surprise at the final step. Registration being forced on a first-time buyer. A phone field rejecting a perfectly valid number. A card step that takes four seconds to load on a phone. Each of these is money leaving, and removing one of them typically does more for revenue than a full redesign would.
So a project starts with the product and order flow rather than with layouts. How many products, how many variants, where stock is managed, how shipping is calculated, how a return is processed, who packs the order and when. The design is then built on top of decisions that have already been made, instead of being decorated around problems discovered later.
