How it works
Your web project, all in writing.
Price and timeline are written down before you sign. Then you see the project move forward at every step.
01
The call
Thirty minutes about your customers, what they come for, and what you already have. No specification needed.
02
The proposal
Scope, price and timeline, in writing. It serves as your brief. The project starts with half of the amount.
03
The build
Two weeks to two months for a website or a store, dated stages for software. You see every stage, and you test an app on your own phone.
04
The launch
The site goes live, then you pay the balance. The code, the domain name and the hosting are in your name.
Your questions
How do you choose a web team?
What people ask us before signing. The rest gets settled on the call.
How much does a website cost?
Each service has a public entry price, with no VAT on top: €3,500 for a custom brochure website, €4,500 for a Shopify store, €15,000 for a mobile app, €1,500 for a logo and its mini brand guide. The firm price follows the call, in writing.
How do I choose a web development team?
Four checks are enough. Live projects you can open yourself. The name of the person who will do the work. A price and a scope in writing before you sign. And who will own the code, the domain name and the hosting at the end: with us, you do.
How long does it take to build a website?
Between two weeks for a focused project and two months for a full website or store. A mobile app moves forward in stages, and its schedule is written in the proposal.
How does payment work?
For a project: 50% at the start, 50% at delivery, by bank transfer or card, with staged payments possible depending on how long the project runs. Monthly services, such as Meta Ads management or SEO support, are paid each month.
Why three specialists rather than a large agency?
A large agency has overheads: account managers, internal sign-offs, fixed costs. You pay for it in delays and on the invoice. Here, the specialist whose job it is works on your project, and decisions are made between the three of us, often the same day.
Can you take over an existing website or app?
Yes. We start with a technical audit, to know the state of the code before committing to a timeline. For a rebuild, we keep or redirect the pages that bring you visits, so you do not lose your search rankings.
Who do you work with?
E-commerce brands, startups and companies with a clear project and a budget set aside for it. We are based in Lille and work across France and Belgium: in person around Lille, remotely elsewhere.
Next step
A free call to frame your project.
To understand your project, your budget and your timeline. The call is in English, with William or Lumbe, and you get a written proposal if we can help.
