Themes are built for the average store. Yours stopped being average the day your catalog grew and orders started arriving from several channels at once. We build custom e-commerce — on Shopify or headless — with stock synced to your ERP, a checkout that holds on launch day, and one rule we never bend: you never sell what you don't have.
Every order you sell without stock gets paid for twice: once with the refund, and again with the customer who never comes back. Every extra second at checkout on campaign day is ad spend sending people to a page that won't load. These aren't one-off incidents. They're what happens when a store built as a shop window is run as an operating system.
So we design it the other way round: the flows first — stock, suppliers, carriers, returns — and the pages after. We work on catalogs from a few hundred to more than 30,000 SKUs, targeting an LCP under 1.2 seconds on every product page and zero overselling in production.
Custom themes, private apps, tailored checkout. Hydrogen or Remix architectures when the standard theme becomes the bottleneck.
Stock aligned with your ERP, suppliers and marketplaces. One source of truth, so what's sold never exceeds what's available.
Variants, customer-specific price lists, tiered discounts and catalogues differentiated by commercial segment.
Connections to GLS, DHL, BRT and SDA: labels generated automatically, real-time tracking, a returns flow with no email threads.
LCP under 1.2s, stable layout, interaction in the green band. Images, lazy loading, CDN and multi-layer caching.
GA4 with e-commerce events, heatmaps, checkout funnel. A/B tests on the steps that lose the most carts.
An e-commerce isn't delivered because "the site shows up". It's delivered when these points are green on real data, not on a clean staging environment.
We analyse the current stack, find the points where the funnel leaks and quantify the impact. The output is a report with priorities ordered by return.
Stack choice, integration map, data migration plan and release calendar.
Bespoke theme, private apps, API connectors. Every integration is tested on real data before it touches production.
Simulated traffic at the expected peaks, verification of the critical flows — checkout, returns, notifications — and sign-off from your team before go-live.
Progressive release behind feature flags, with an immediate rollback if something looks wrong. Active monitoring through the first 72 hours.
You don't pick a platform because it's fashionable. You pick it for the point where your store stops keeping up. This is the rule we use during the audit.
| If your situation is… | The sensible choice |
|---|---|
| A contained catalog and a tight launch date | Shopify with a custom theme |
| The theme has become the bottleneck: speed, experience, variants | Headless Shopify, on Hydrogen or Remix |
| Customer price lists, tiered discounts, B2B selling | Shopify with custom B2B logic |
| Several suppliers and marketplaces on the same stock | Shopify or headless, plus a sync middleware layer |
We don't show client logos. We show how we think: three full technical breakdowns, from the architecture to the choices that matter once the catalog grows.
Replatforming is when stores lose the most organic traffic, almost always through avoidable mistakes: missing redirects, product pages that change URL, structured data that disappears. We plan the migration around what brings visits and sales today, and protect it before touching anything else.
How to relaunch a site without losing rankings
A free analysis of your current store: where it loses orders, ranked by impact, and an estimate of what fixing it costs. If it isn't worth fixing, we'll tell you.
A well-configured Shopify theme starts at a few thousand euros and is the right call while the catalogue is simple and the processes are standard. Custom runs from a few tens of thousands upwards, and makes sense when a measurable problem justifies it: supplier synchronisation, catalogues beyond a few thousand SKUs, pricing logic no theme anticipates. The useful question is not what it costs, but what the manual work it would replace is costing you today.
Shopify when your edge is in the product and the marketing rather than in the mechanics of the shop: payments, security and updates stay someone else's job. Headless when you need performance or experiences a theme cannot carry, but want to keep Shopify as the order engine. Fully custom only when the business model fits neither — marketplaces, B2B with per-customer price lists, complex configurators.
You need one source of truth for stock and a reservation taken at order time, not at shipping time. The rest is integration discipline: every channel reads and writes the same warehouse, conflicting writes are rejected by the database rather than resolved by whoever arrives last, and every mismatch leaves a record you can inspect.
A migration onto a well-built theme: six to eight weeks. A custom e-commerce with ERP and supplier integrations: three to five months, with a usable first version well before the end. Timing is almost always set by the integrations, not the interface: how many systems must talk to each other and what state their data is in.
