Digital Agency · Brussels

We build.
You grow.

Q: How much does a custom website cost?

Every project is custom, so the price depends on scope, not on a rate card. You get a fixed quote within 48 hours of our first call, sized to your goals and your market. No hourly surprises, no hidden fees.

Q: Why not just use Webflow, Wix, or WordPress?

Templates and page builders get you online fast, but they cap your performance, SEO, and design the moment you outgrow them. We hand-code every site in Next.js, so it loads in under a second, ranks higher, looks like nobody else’s, and never hits a platform wall.

Q: How fast can you deliver?

Most websites go live in 3 to 4 weeks from brief to launch. AI chatbots can ship in as little as 1 week, and complex platforms take 6 to 10 weeks. We give you a realistic timeline before we start, and we hit it.

Q: Can you integrate with our CRM, ERP, or existing tools?

Yes, it’s one of our core strengths. We’ve built direct API integrations with Odoo, HubSpot, Salesforce, Stripe, and custom ERPs. If your tool has an API, we connect it, so leads flow straight into your CRM and your team never copies data by hand again.

Q: Do you handle e-commerce and online payments?

Yes. We build custom e-commerce from scratch: bespoke checkout flows, Stripe payments, order management, and product catalogues, with no Shopify or WooCommerce limits. Your store works exactly the way your business needs, with zero compromise on speed or design.

Q: Can we update the site ourselves after launch?

Absolutely. We build a custom admin dashboard around your workflow so your team manages content, products, and data without touching code. No generic CMS to fight, you own your site and your data completely.

Q: What happens after the site goes live?

We offer monthly retainers for maintenance, security updates, new features, and performance monitoring. Most clients stay on because it’s cheaper than a full-time developer. We become your on-call technical team.

Q: What makes WCS different from other agencies?

No account managers, no bloat, no templates. You talk directly to the people building your project, every line of code is written for you, and every project ships with a defined success metric so you always know what you paid for.

Q: What technologies do you use?

Next.js, React, and TypeScript for the web, Stripe for payments, and custom API integrations for CRMs and ERPs. For AI we build on modern large language models, and for automation we use Make, n8n, Zapier, and custom Node.js or Python.

Q: Where are you based, and do you work outside Belgium?

We’re based in Brussels and work with clients across Belgium, the Netherlands, France, and Luxembourg, plus projects in the UK, Germany, and the UAE. Everything runs remotely with regular video calls and clear communication throughout.

Websites, AI chatbots, and automation, hand-coded from scratch in Brussels and live in weeks, not months.

We don’t just build interfaces. We choreograph pixels. Static design is a photograph but this is a performance. Every scroll is a keystroke, every pixel is deliberate, and motion is the only language that moves people.

How we work

From first call
to launch in weeks.

A clear, fast process with no endless feedback loops. Here is exactly what working with WCS looks like.

Week 1

Discovery & Design

We dig into your goals, audience, and competitors, then design the full experience in high fidelity. You approve before a single line of code is written.

Week 2-3

Build

We hand-code everything from scratch in Next.js. You get a live preview link from day one and watch it come together in real time.

Week 4

QA & Polish

Cross-browser testing, performance tuning to Lighthouse 95+, accessibility checks, and SEO groundwork, before anything goes live.

Launch

Go Live & Grow

We ship, monitor, and stay on call. Most clients continue with us on a retainer to keep improving long after launch.

What Clients Say

They chose WCS.
Here’s why.

★★★★★+34% repeat orders

“Honestly we weren't sure at first. We'd been burned before. But from the first call something felt different. They actually pushed back on some of our ideas, which turned out to be right. Our customers come back now, and so did we.”

★★★★★Paid back in 4 months

“I'll be honest, I thought the load time stuff was marketing speak. It wasn't. The site feels instant and you can see it in the numbers. It paid for itself faster than I expected.”

★★★★★~12h/week saved

“I was the skeptic in the room when we talked about automation. I'm not anymore. The busywork just runs itself now. Nobody on the team has to think about it.”

★★★★★-68% support load

“Our support inbox used to be chaos. Now the chatbot handles most of it and we only see the stuff that actually needs us. Customers don't even realize it's a bot half the time.”

★★★★★Zero downtime

“Two agencies said the Odoo integration was too complex. WCS just did it, and it hasn't broken since. I don't know what else to say.”

★★★★★100% custom-built

“I kept saying I didn't want it to look like a 'web agency made this.' And it doesn't. People ask me who did the site more than they ask about anything else. That says everything.”

★★★★★3x more inbound

“We'd been putting off the website for two years because we were scared it would cheapen the brand. It did the opposite. A buyer from a concept store in Paris reached out because of the site. That had never happened before.”

★★★★★Live in 3 weeks

“Three weeks. I've had agencies take that long just to send a proposal. And the quality was actually there, not fast and sloppy. I've recommended them twice since.”

★★★★★+22% conversion

“They told us one of our feature ideas was going to hurt conversion. We ignored them. They were right. That kind of honesty is worth more than just doing what you're told.”

★★★★★48h to proposal

“I sent an email at 9pm on a Tuesday not expecting much. Response at 11pm, proposal two days later, live in three weeks. I've worked with bigger agencies that couldn't match that.”
