E-commerce agency: Shopify & custom stores
In most cases, we build your store on Shopify: smooth checkout journey, custom theme, payment and logistics integrations, fast go-live. When your catalog, your processes or your ambitions go beyond the standard, we move to custom or headless.
Shopify or a custom e-commerce site: how to choose?
For most e-commerce projects, Shopify is our go-to choice: reliable, fast to launch, with a mature payment and logistics ecosystem. Custom or headless becomes relevant when your catalog, your processes or your journeys go beyond the standard: highly configurable products, a multi-vendor marketplace, a complex B2B area, deep ERP integrations. We choose the stack that's most cost-effective for you, not the most impressive one.
Why are your sales capped by the platform?
Slow pages, abandoned carts, a time-consuming back-office: the solution that got you started becomes a brake the moment you want to accelerate.
Conversion slumping
Slow pages, a complicated checkout funnel: one point of friction costs several points of conversion. And the off-the-shelf platform won't let you fix it.
An experience you can't differentiate
Closed templates, paid modules, limited performance: you look like every competitor using the same solution.
Logistics that saturate
Inventory sync, carriers, marketplaces: everything goes manual when volume climbs. A bottleneck that holds back your growth.
A store built to sell
We start from the checkout journey and your context: Shopify in most cases, custom when the need calls for it. A fast front end wired to your inventory, your payments and your carriers, and a back-office that no longer eats up time.
A frictionless checkout journey
Search, filters, product page, checkout: every screen worked for conversion. Zero unnecessary step between the decision and the purchase.
Shopify first, custom when needed
Shopify is our go-to stack to launch fast and well. Headless or custom development when the catalog, logistics or business rules go beyond the standard.
Inventory & logistics in sync
ERP, OMS, carriers, marketplaces: everything wired from launch, with no manual entry.
What do you gain with the right e-commerce stack?
We aim for the right KPIs: conversion rate, average order value, time spent in the back-office.
More conversion
Fast pages, a smooth journey, a short checkout: every tenth of a second saved translates into conversion points.
A livable back-office
Inventory, orders, returns: centralized control, native automations. Your teams handle more volume without growing.
A brand that stands out
A custom Shopify theme or bespoke design: an experience that breaks out of the standard template, without sacrificing performance or SEO.
Scalable by nature
Multi-country, multi-currency, marketplaces: we add capabilities without rewriting the base.

Contact usThe cost depends on the scope and the chosen stack. A Shopify store with a custom theme and targeted integrations starts far cheaper than a custom or headless e-commerce site with ERP integrations. As an e-commerce agency in Paris, we scope your needs upfront and give you a clear estimate before starting. The investment is usually paid back quickly through conversion gains and operational savings.
Building a high-performing e-commerce site goes through four steps: choosing the right platform for your catalog (Shopify in most cases), designing a frictionless checkout journey before any development, integrating inventory, payment and logistics from the start, then optimizing continuously after launch using real data. We guide you through all of these steps.
Shopify is our go-to choice for most projects: fast launch, mature ecosystem, manageable maintenance. Custom or headless is justified when you have your own business rules, multi-vendor needs, complex logistics or ambitions that Shopify doesn't cover natively. We guide you without dogma, based on your context and budget.
