They trust us
Your online sales business
You want to sell directly to consumers, open an ordering portal for your business clients or enhance an existing store. Our ecommerce development agency helps you define the right features, then design and implement them. We start from your catalog, your terms of sale and your organization to build a solution your teams can use every day.
The project can cover building your ecommerce website, a product configurator, customer-specific pricing or a connection to your management software. We review what the platform already offers, the available extensions and the custom development required. You can then choose the features essential at launch and those to build later, with their cost and constraints.
If you need to replace an existing store or change platforms, our ecommerce redesign service also covers data migration and the move.

Choosing your ecommerce solution
Hosted solution
Shopify suits companies that want to rely on a hosted platform to run their store. We adapt the theme to your brand, organize the catalog and integrate the apps and connections you need.
We check the customization options, the plan required and the recurring costs before choosing this solution, especially for payments and B2B needs.
Catalog management
PrestaShop lets you build a store whose catalog, sales rules and modules can be adapted to your business. We develop the theme, configure the features and build the connections you need.
The choice also takes into account hosting, module compatibility and maintenance, to plan how the store will run after launch.
WordPress ecosystem
WooCommerce adds online selling to WordPress. This solution can be a good fit when your content and your store need to share the same environment. We design the sales pages and adapt the plugins to the intended uses.
We assess performance, security and updates across the whole stack: WordPress, theme, plugins and hosting.
The purchase journey before development
Your customers need to find the right product, understand its features and order easily. In workshops, we organize categories, search, filters and the information to display with you. The journey takes into account mobile usage, your products and your brand identity.
Our designers, including Awwwards award winners, create the mockups in Figma: category pages, product pages, cart and the main checkout steps. A prototype lets you click through the screens and share your feedback before development. Checkout customization options are checked against the chosen platform.
You approve the design and the user journeys before integration. We pay particular attention to the readability of prices, availability and shipping costs, so your customers have the information they need when ordering.
Your store's features
Configurator, subscriptions or specific ordering rules: we study your needs to choose between native feature, extension and custom development. The goal is to meet your business needs with a solution you can maintain and evolve.
We structure categories, variants and filters to make search easier. Product pages show the information needed to buy, with data your teams can keep up to date.
We integrate the chosen payment methods and shipping options. Cart, promotions, fees, confirmations and refunds go through testing on complete order scenarios.
For a B2B project, we set up company accounts, negotiated pricing, quote requests and approval rules. Your commercial terms guide the choice of extensions and custom development.
Your tools connected to the store
An order placed online should be processed by your teams without duplicate data entry. Our ecommerce development agency sets up data exchanges between your store and your software: ERP for order and inventory management, CRM for customer relationships, PIM for product information.
With the people who manage your tools, we define which data flows, in which direction and how often. We check the available connectors or build a connection through APIs, the interfaces that let software communicate. Feasibility depends on the access and capabilities of each tool.
Testing covers real cases: price changes, stockouts, canceled orders or refunds. We also plan how to detect a failed sync and resume processing. You know where to update your data and how to monitor the exchanges.
Developing your ecommerce website includes the technical foundations of SEO on Google: category structure, URLs, internal links, handling of filters and variants, relevant structured data and loading speed. We also set up tracking for add-to-cart events and purchases. Content strategy and long-term SEO monitoring can be covered by additional support.
From specification to first orders
We clarify your customers, your catalog, your sales rules and the tools to connect. A product sample lets us check variants, prices and required data before the full import. The specification sets the features, responsibilities and acceptance criteria, separating the launch from later improvements.
We build the journeys and mockups with your teams. You approve the screens and expected behavior before integration, with decision points identified in the schedule.
Our developers configure the platform, integrate the design and build the custom features. Connections to management tools are tested step by step, in a working environment separate from the live store.
With you, we test orders on mobile and desktop: variants, promotions, accepted or declined payment, shipping and confirmations. We also check refunds and the data sent back to your management tools. Tests run in the available test environments; live checks are agreed with you before opening.
You learn to create a product and its variants, prepare an order and edit your content. We hand over the agreed access and documentation, then monitor the first orders and data exchanges. Updates and next improvements are organized with your team.
We break down design, development, integrations and testing. Subscriptions, extensions, payment fees, hosting and maintenance are listed separately. The schedule specifies the content and approvals expected from your team.
Request a quoteHow we support you
Our consultants help you clarify your commercial needs and choose the platform. Designers build the journeys, then developers build the store and its integrations. You talk with the people working on your project, during mockup reviews and demos. After launch, our ecommerce development agency can handle maintenance and new features, according to your priorities and the contract defined together.
Your next online sales project
Before you start
The budget depends on the design, the platform, the quality of product data and the features to develop. Connections to management software can be a significant part of the project. We prepare a detailed quote after scoping, separating the build from recurring costs: subscriptions, extensions, hosting and maintenance.
