How Much Does a Custom Website Cost in Belgium?

A fully custom website for a Belgian business typically starts at around €8,000 and can pass €25,000 for large projects, while template-based sites cost far less. These are our own rough ranges, not survey data: the real price follows the design, the number of pages, the features, the content and the maintenance you need.

The main pricing tiers

Template or no-code: roughly €500 to €3,000

Wix, Squarespace, Webflow or a premium WordPress theme. Quick to set up, but you work inside the template, so it is hard to look different from other sites built on the same one. It suits a side project or a young business testing its market.

Semi-custom: roughly €3,000 to €8,000

A developer or small agency adapts an existing theme to your brand. This is more flexible than a raw template but still limited by the architecture underneath. It is the grey zone where many clients believe they bought a custom site and actually received a modified WordPress theme.

Fully custom: from roughly €8,000

Designed and built from scratch, without a template. The interface is drawn for your brand and the code is written for your needs, which is what you pay for when you want specific layouts, integrations or performance targets.

Agency or freelancer?

A freelancer is usually cheaper for the same number of days, and works well for a simple project with a clear brief. An agency brings a team: designer, developer, project manager and copywriter, which helps when the site needs careful design, written content and technical integration.

The main risk with a solo freelancer is availability: illness, holidays or a priority project elsewhere can stall delivery. An agency can usually replace a person. Weigh that against your timeline.

What drives the price

• Design: original design is often the most underestimated item. Ask how many concepts and revision rounds are included.
• Number of pages and page types: a landing page costs less than a 20-page site with different layouts.
• Features: forms, online payments, client portals, AI chatbots and animations each add work.
• CMS: if you want to edit content yourself, a content management system has to be integrated and explained.
• Content: copywriting, photography and video cost extra if the agency produces them.
• Languages: a site in French, Dutch and English needs structure for three languages plus translation and proofreading.

Running costs to plan for

The development quote is only part of the cost. Plan for these as well:

• Hosting: basic shared hosting costs a few euros a month, while platforms such as Vercel charge by plan and usage. At the time of writing, Vercel's free Hobby plan is restricted to non-commercial use, and developer seats on its Pro plan cost $20 per user per month (Vercel documentation, October 2026).
• Domain name: an annual fee that depends on the registrar and the extension (.be, .com, .eu).
• SSL certificate: included with most modern hosts, but confirm it in the quote.
• Licences: some plugins, fonts or design tools are paid yearly.
• Maintenance: security updates, backups and monitoring, either by your agency on a retainer or by someone in your team.

How to read an agency quote

A good quote lists the days per item (design, development, CMS integration, testing, launch) and defines the revision phase. Be wary of a single total with no breakdown of deliverables, because it makes comparison and later discussion harder.

Always ask three questions. How many revision rounds are included? Who hosts the site, and what happens if I want to change agency? Do I own the source code at delivery? The answers tell you a lot about who you are dealing with. Also check whether prices are quoted with or without VAT.

Warning signs of a very low quote

A fully custom site for under €2,000 is very unlikely to be what it says: it is more probably a customised template. That can be fine when it is stated openly, and misleading when it is sold as bespoke. In the same way, a complex site promised in a few days deserves questions about who is actually building it.

How to judge whether the price is worth it

A website pays for itself through the enquiries and sales it brings. A simple test is to multiply the extra enquiries by the share that becomes a client and by the value of a client, then compare that with the cost.

An illustration with invented numbers: a site gets 500 visitors a month. If 1% contact you, that is 5 enquiries, and at 2% it is 10. If one enquiry in five becomes a client worth €2,000, those 5 extra enquiries are worth €2,000 a month. Better design and clearer calls to action can raise the share of visitors who get in touch, but no agency can promise a specific increase.
