The problem Every sale pays a toll, and the lease gets renegotiated without you.
Same supplier photo, same copied description, twelve sellers on the same reference. The buyer takes the cheapest and you will never know you were compared. Your margin gets decided without you.
Your products look good in real life, your selection took years to build. Online: a grid of identical thumbnails and text lifted from the supplier catalogue. Nothing that sets you apart in store survives on screen.
A four-step checkout, a redirect to an unfamiliar page, a payment method missing at the wrong moment. The customer leaves, the cart stays, and all it leaves you is a number with no explanation.
A subscription, a percentage on every transaction, and a thirty-euro-a-month add-on every time a feature is missing. Your growth funds somebody else's infrastructure, and the bill climbs with your revenue.
The solution You pay for the build once, and every sale after that is entirely yours.
And your customers buy from you, not from a results grid.
Your selection, your convictions, what you refuse to stock and why. That is what makes people pay three euros more with you than elsewhere. A shop with a voice steps out of the penny-by-penny comparison.
Large-format photos, the use properly told, clear materials and sizes, instant display on mobile. Your products come across online the way they come across on the shelf. And you add a reference, a price or a promotion in a few clicks, without calling anyone.
One-page payment, Bancontact on the same footing as cards, two-tap confirmation on a phone. Plus tracking that shows you exactly where carts are lost, so you correct instead of guessing.
No percentage taken on your sales, no subscription that climbs with your revenue: only your payment provider's fees apply, as they do everywhere. Your product pages show up on Google and in AI answers, and that visibility belongs to you.

You don't talk to a salesperson who reports to a project manager, who briefs a developer and a designer: all those people sit in front of you, in one person, from the very first meeting.
from €595
Before a single line of code, we clarify the buying journey and the image your brand projects. The design then does the work of creating desire and clearing doubts before payment.
from €1,190
I build your shop from scratch: it loads in under a second and turns visitors into orders. Bancontact and cards integrated from day one, catalogue managed independently, and code that is 100% yours.
from €595
Your customers search for a product on Google and ask ChatGPT for advice before buying. I structure your product pages so they show up in both places, and I send you the ranking report so you can watch it move.
from €595
Cart recovery, confirmations, order tracking, stock synchronisation: I automate what fills your days, with or without AI. Measurable results within 4 to 6 weeks.
I don't hand over a project and vanish. Updates, optimisations, A/B testing and dashboards: I stay your partner for the long run.

25 minutes to look at your situation together: what your platform takes from you every month, where your checkout loses customers, what your product pages weigh on Google today. You leave with a clear diagnosis, even if we never work together.
It's free, there's no commitment, and you get me directly on the phone. The developer you talk to is the one who will build your shop.
The cost of a custom e-commerce website depends on the scope: number of products, payment integrations, inventory management and how much automation you need. A shop built with Snipcart (simple catalogue, Stripe and Bancontact payment, up to a few hundred products) starts at around €5,000 to €8,000. A more advanced site with Medusa.js (multi-currency, vendor portal, order automation) starts from €16,000. In both cases there is no commission on your sales and no monthly subscription to a third-party platform. A 25-minute call is enough to scope your requirements and give you an estimate.
An online shop built with Snipcart (product catalogue, integrated payment, order management) is delivered in 4 to 6 weeks. A more complex e-commerce project (dynamic catalogue, multi-stock management, ERP integrations or advanced automation) requires between 10 and 16 weeks. The timeline depends directly on functional complexity and the speed of your sign-offs. The wireframe and validation phase runs before development: what you approve is what gets built.
Shopify is a convenient way to start quickly, but its business model gets in the way as you grow: commission on sales, a subscription that climbs with the features you add, and limited room to customise without going through its ecosystem of paid plugins. With Snipcart or Medusa.js you pay no commission on your transactions, the code is yours, you host it where you choose and you can change it without asking a platform.
Run the three-year calculation with your own volume before deciding: below a certain turnover, Shopify stays the cheaper option, and I will say so.
I integrate the payment methods that matter on the Belgian and European market: Stripe (Visa, Mastercard, American Express), Bancontact, which is the most used method in Belgium, PayPal, plus Apple Pay and Google Pay for mobile. For B2B, deferred payment (Klarna, Alma) or automated SEPA transfers can be added. Every integration complies with PSD2 and 3D Secure.
SEO for e-commerce is a topic in its own right. I handle native technical SEO from the development phase: clean canonical URLs for each product and category, Schema.org structured markup (Product, Offer, BreadcrumbList), dynamic XML sitemap, OpenGraph tags for social sharing, and optimised load times (PageSpeed 95+). Product pages and category pages are designed to be both readable by Google and optimised for conversion. I can also support you with a full SEO/GEO strategy to position your shop on high-commercial-intent queries in your sector.
The complete source code of your shop lives in your own Git repository (GitHub, GitLab or Bitbucket) and you own it from day one. Secure access is shared with developers I trust who know the project. It is built with standard open-source technologies (Astro, Snipcart, Medusa.js, Node.js), so another experienced developer can take over, and the technical documentation is delivered with it.
What I cannot promise is being available forever; what I can guarantee is that my leaving does not block you.
Price The cost of an e-commerce website in Belgium depends mainly on what customers must be able to do without your intervention. This guide connects three practical project levels to Numinam budget ranges and highlights the costs that should appear separately in any serious quote.
