Shopify agency expert in creation, redesign, and optimization
Agence Shop supports brands that want to make Shopify a real growth driver. We design, redesign and optimize online stores by combining e-commerce strategy, user experience, design, development, natural referencing and conversion rate optimization.
An agency entirely specialized in Shopify
Agence Shop focuses on Shopify. With over 15 years of digital and e-commerce experience, it has supported more than 80 brands in France and internationally.
As a Shopify Partner, we closely follow the platform's developments. Each client interacts directly with Olivier Romero, the agency's founder and senior project contact. This approach ensures a precise understanding of the challenges, right through to post-launch follow-up.
Our approach: strategy, UX, CRO and development
A high-performing Shopify store isn't just about its appearance. It must quickly explain what the brand offers, facilitate product discovery, address objections, and guide every visitor to purchase. It must also remain fast, stable, and simple enough to administer so that it can evolve without continually rebuilding what already exists.
-
E-commerce strategy
We define priorities based on your positioning and data. The objective is to sustainably improve the conversion rate, average basket, and repeat purchases.
-
Mobile-first user experience
The journeys are primarily designed for smartphones: everything is organized to make the experience clear, fast, and natural.
-
UX / UI Design
The interface translates the strategy into a premium and custom-made universe. The artistic direction enhances products and asserts the brand's identity.

Clean Shopify development
Liquid, JavaScript, HTML, and CSS allow us to create a unique experience. The code is structured, performant, and manageable.
OUR SHOPIFY DESIGN, REDESIGN, AND OPTIMIZATION SERVICES
Every Shopify store encounters different challenges depending on its maturity level, catalog, and objectives. We therefore adapt our support to the real situation of each brand: creating a new site, redesigning an existing store, improving its sales performance, or developing the functionalities necessary for its evolution. Each intervention responds to a precise need and is part of a sustainable vision for the project.

Build a Shopify Store on Solid Foundations
We design Shopify stores tailored to each brand's positioning, business model, and actual operations. To do this, we clarify the value proposition, define a fluid and optimized sales funnel, design the catalog to access any product in two clicks, structure the benefits and reassurance elements, and integrate the store into an ecosystem of high-performance applications. Finally, we ensure that your team can easily take over.

Conversion-focused Shopify redesign
Learn more about conversion-focused redesignsA redesign becomes necessary when a store no longer reflects the brand’s positioning, lacks fluidity on mobile, or relies on a theme that has become difficult to maintain. We analyze the existing situation before reviewing the architecture, navigation, product pages, reassurance, and decisive steps of the purchasing journey. Therefore, the project is not just about a simple change in appearance: it must solve identified problems, reinforce perceived value, and prepare for future developments.
-
Improve conversion rate without diluting the brand
Shopify CRO Audit to Improve Conversion RateWhen a store attracts visitors but doesn't generate enough sales, we look for the reasons that are holding back their decision. The audit covers the offer, navigation, mobile experience, product pages, shopping cart, and trust elements. Behavioral observations and available data then allow us to prioritize recommendations based on their potential impact and complexity. The brand thus obtains a concrete action plan to improve its conversion without multiplying unnecessary changes.
-
Shopify landing pages
Discover our Shopify landing page creation service.An advertising campaign, a launch, or a strategic offer often warrants a separate page from the classic catalog. We design landing pages that clearly articulate the promise, benefits, proofs, and call to action. Their structure guides the reader without resorting to aggressive commercial mechanisms that could weaken the brand image. The design remains faithful to the store's universe, while development ensures smooth viewing on smartphones.
-
Migration to Shopify
Migrating from another CMS (WooCommerce, PrestaShop, WiziShop, or another solution) requires more than just a product transfer. We prepare the transfer of the catalog, variants, customers, orders, and content based on the capabilities of the original platform. Special attention is paid to existing addresses, redirects, and metadata to limit risks to natural search engine optimization. The new store is then tested before the switch to secure data, payments, statistical tracking, and main user journeys.
-
Maintenance and Evolution
A Shopify store continues to evolve after its launch. We can fix bugs, update the theme, create new sections, integrate apps, or support key sales periods. Monitoring also allows us to observe performance and prioritize improvements based on real usage. The goal is not to continuously add features, but to maintain a reliable technical foundation and to advance the site at the pace of the brand, its catalog, and its business objectives.
SHOPIFY FOR PREMIUM AND LUXURY BRANDS
A high-end brand must preserve its desirability while making the purchase obvious. We translate its positioning into a tailored artistic direction, a carefully crafted editorial hierarchy, and discreet interactions, without sacrificing speed or clarity. Perceived quality is built into every detail: page rhythm, visual treatment, typography, storytelling, and service. This requirement guides our projects for brands that refuse to choose between image and performance. Discover our luxury and premium Shopify agency.

Results from Real-World Projects
Bell's Cookies: a shop designed to boost sales
This American brand, which sells over 500,000 cookies per month, needed a clearer platform for its bundles, subscriptions, and mobile experience. After a comprehensive audit, we revamped the experience, design, and development. Sales increased by 101% compared to the previous period. The variation corresponds to the difference between sales in the two periods, relative to the reference period. Juliana Arb highlights a "functional and high-quality" platform. See the Bell's Cookies case study.
Why choose Agence Shop for your project?
Agence Shop was founded by Olivier Romero, a digital and e-commerce expert for over fifteen years. This experience allows us to approach Shopify with a vision that goes beyond development. A technical decision can influence conversion, maintenance, natural referencing, or the daily work of the team. We therefore ensure that each choice remains consistent with the entire project.
You will communicate directly with a senior contact person capable of understanding the commercial, creative, and technical dimensions of your request. This organization makes communication smoother and limits information loss between the reflection phase and implementation.
We also place great importance on knowledge transfer. A successful store should not make its owner dependent on a developer for every simple change. The theme, sections, and content are designed to offer a balance between customization and autonomy. When trade-offs are necessary, we explain them so that you can make your decisions understanding their advantages and limitations.
When to use a Shopify agency?
Using a Shopify agency is relevant as soon as a project goes beyond a simple theme installation. It can support the creation of a new store, a complete redesign, or a migration from WooCommerce, PrestaShop, WiziShop, or BigCommerce. Its intervention then makes it possible to define a coherent architecture, preserve data and natural referencing, and then build an experience adapted to the brand's commercial objectives.
A specialized agency also becomes useful when an existing store no longer meets expectations: insufficient conversion rate, too low average basket, confusing navigation, unconvincing product sheets, or degraded mobile experience. Analyzing data and behavior makes it possible to identify the real friction points, then prioritize improvements likely to facilitate purchases, strengthen loyalty, and sustainably support growth.
This support finally takes on its full meaning during an upgrade, international development, or a significant change in activity. The deployment of multiple languages and markets, the integration of an enterprise resource planning system, a logistics solution, or strategic applications require reliable technical choices. The same applies when a theme becomes difficult to maintain or when custom functionalities are needed. A Shopify agency then combines e-commerce strategy, user experience, design, and development so that each decision serves performance, brand image, and the future evolution of the store.
How much does it cost to work with a Shopify agency?
The budget mainly depends on the scope of work. A store built from a carefully customized theme does not require the same investment as a complete redesign including a new identity, several custom templates, data migration, and connections with external tools.
The number of pages is not the only criterion. The complexity of the catalog, expected functionalities, languages, SEO recovery, and the level of support also influence the scope. We therefore start by studying the project before proposing a detailed estimate. This initial discussion helps distinguish what is essential for launch from what can be developed in a later phase.
Our goal is to create an investment that is consistent with the brand's commercial objectives, rather than adding features whose value would remain uncertain.
