White-label Shopify development for agencies
Your agency signs the e-commerce projects, we build them: custom Shopify themes, customisations, migrations. Delivered under your brand, on your timeline. Subcontractor to several French and European agencies since 2013.
14+ years of web development
300+ projects delivered, all stacks combined
100% white label, zero end-client contact
+2h ahead of Central European Time
The principle
You sell. We build.
Your clients ask for Shopify, but hiring an e-commerce developer for a handful of stores a year doesn't add up. We take on the technical production: custom themes, Online Store 2.0 sections, checkout-funnel tuning, app integrations. You stay the agency: the end client never hears from us, never sees our name.
Concretely, you send a brief or a mockup, we quote within 24 business hours, build on a staging environment, and you ship under your brand. Your back-and-forth with the client stays with you; ours happens with your project lead.
We've run this model since 2013, in full white label, with several French and European agencies. Custom themes, section-level customisation, WooCommerce or PrestaShop migrations to Shopify: over 300 projects delivered, from a small theme tweak to a full storefront rebuild.
What we build Themes, customisations, migrations.
Themes, customisations, migrations.
You choose, we deliver.
Customisations & features
Specific sections, business logic, conversion optimisation, integrations. Surgical, documented, without breaking theme updates. We also tune the checkout funnel within what the platform allows.
Migrations to Shopify
From WooCommerce, PrestaShop or elsewhere. Products, customers, orders, redirects: SEO survives the move, with URL mapping and 301s checked before launch.
Maintenance & improvements
Ongoing upkeep of the store under your brand: updates, fixes, small improvements as your client's needs evolve. Your agency bills the peace of mind, we handle the quiet nights.

How it works From your brief to delivery,
From your brief to delivery,
in four steps.
1
The brief
Send the brief or mockup (Figma, XD, PDF, whatever works). A couple of lines and a link are enough to get started.
2
The quote
Quote within 24 business hours, fixed price. No sales funnel, no lengthy discovery call.
3
Production
Production on a staging environment, QA across browsers, mobile and checkout. You track progress without having to ask.
4
Delivery
White-label delivery, on your store, live. Maintenance option after, under your brand too.
The ground rules
What we guarantee.
- Full white label: we never appear anywhere, no contact with your end client, ever.
- The deadlines we quote are the deadlines we hit: that's what we're judged on.
- Proactive communication: you know where the project stands without having to ask.
- NDA signed if you want one.
- Invoicing in euros, SEPA transfer.
The timezone advantage
We start before you do.
Based in Mauritius, we run 2 to 3 hours ahead of Central European Time. A mockup sent in the evening is often integrated by the time your day opens; a checkout bug flagged at 6pm can be fixed before your first coffee.
The timezone is the only thing that separates us from a provider down the road. Exchanges in English or French, invoicing in euros by SEPA transfer, availability through your office hours. We have worked with French and European agencies since 2013: same standards as anyone in Europe, plus the head start.
Who this is for Three situations where subcontracting
Three situations where subcontracting
pays off for your agency.
No in-house Shopify developer
You sell Shopify builds and revamps, but production goes to a different freelancer every time. One technical contact, consistent quotes, and quality that no longer depends on who happens to be free.
Design or branding studio
Your Figma or XD mockups deserve a pixel-accurate build. We code what you designed, without reinterpreting it, so your art direction reaches the live store intact.
Overflow capacity
Peak load, holidays, projects stacking up: your team keeps the core work, we absorb the rest. You hand the capacity back once things calm down, no hiring, no commitment.
Frequently asked questions Everything you want to know
Everything you want to know
before handing us a project.
Do you work on existing stores?
Yes, after a quick audit of the theme and installed apps. Most of our engagements start on existing setups.
Will the end client know you exist?
No. Delivery happens under your brand, and communication runs only with your team.
Can you customise checkout?
Within the platform's limits: Shopify reserves deep checkout customisation for Plus plans. We optimise everything that's allowed, cleanly.
Does a migration hurt SEO?
Not if it's done properly: URL mapping, 301 redirects, tags preserved. That's the core of our migration process.
What's the turnaround?
A customisation takes days, a full theme takes 2 to 4 weeks. The deadline is fixed at the quote stage and held.
How does invoicing work?
In euros, by SEPA transfer. A deposit based on project size, with the balance due on delivery.
What does it cost?
It depends on the scope: a customisation is not priced the same as a full custom theme. Every project gets a fixed quote within 24 business hours, and the price agreed at the quote stage doesn't move once we start.
What technologies do you master?
Shopify first: Liquid, Online Store 2.0 sections, the theme and app ecosystem. We also cover WordPress and custom HTML/CSS/JS builds when an agency needs both. Over 300 projects delivered since 2013, across stacks. And we tell you plainly when a project falls outside our scope.
How do we start?
Send a first test project: a theme section, a checkout tweak, a small fix. We deliver it, you judge the result, and you decide what comes next. No commitment.
The simplest way to judge us: a test project.
No commitment. A custom section, a theme fix, a small migration: we deliver it, you decide from there.
