What is an Ecommerce Experience Agency?
An ecommerce experience agency designs and builds the storefront, then keeps working on it after launch: the design system, the templates, the merchandising and filter logic, the checkout, the platform underneath, and the testing rhythm that keeps all of it honest.
It sits between two disciplines that usually stay apart. A design studio makes something handsome and hands over a file. A development shop builds what the ticket says. The work that moves revenue lives in between, where the visual decision and the technical decision are the same decision, made by people who will still be there when the catalog doubles.
Atelier works across Shopify, Shopify Plus, and BigCommerce, with headless builds where the catalog genuinely calls for one. The same people who diagnose the problem are the people in the theme. That is the whole argument for an atelier rather than an agency, and it is the reason the last ten percent of a build actually gets finished.
Five practices sit under this page. They are usually bought together, and they can be bought singly.
The Five Practices
Conversion Rate Optimization
Research, prioritization, and testing aimed at the share of visitors who buy, measured in revenue per visitor rather than conversion rate alone. This is where the audit and the testing programme live.
UI & UX Design
The design system, the template hierarchy, and the interface decisions that determine whether a buyer finds the answer or leaves looking for it.
Ecommerce Web Development
Theme architecture, app rationalization, speed, and the build work that keeps a storefront maintainable by the brand's own team.
Replatforming
Moving a store to Shopify Plus or BigCommerce with the catalog, the URLs, the integrations, and the search equity intact. The dependency audit comes before the migration plan, always.
Strategic Merchandising
Collection logic, product sequencing, search relevance, and the rules that let a brand's own team merchandise without a developer.
