How much does a website cost for a Brussels business in 2026?

A professional brochure website for a Brussels business typically falls between €1,500 and €5,000 excl. VAT. For a functional online store, budget rather from €5,000 to €15,000 excl. VAT, or more if your needs are complex. These amounts cover design, custom development, and basic technical SEO, but not ongoing costs.

These ranges aren't inflated figures: they reflect serious work, designed to convert visitors into customers. A rushed €800 site will cost you far more in lost revenue. Below, we detail what makes the final bill vary.

A typical brochure site for a local business (restaurant, salon, physical shop) comprises 5 to 10 key pages: homepage, services, about, contact. Starting at €1,500, you get a custom design, flawless mobile responsiveness, and optimization for Google Business Profile.

If you entrust content writing to the agency or want features like online booking, the budget can approach €3,500 to €5,000. In this range, the provider delivers a lightweight, fast site built to last, not a simple tweaked template.

E-commerce demands a solid infrastructure: product catalog, cart, secure payment gateway, inventory management, customer accounts. For a medium-sized store using WooCommerce or PrestaShop, budget at least €5,000 for a well-architected project.

With hundreds of SKUs, complex variants, Belgian payment gateways (Bancontact, Payconiq), and accounting integration, the price rises to €10,000–€15,000. Shopify-type solutions involve lower initial costs (setup around €2,500) but high monthly subscriptions that add up over time.

Taking over an existing site isn't just hitting 'reset'. A full visual redesign with content preservation and redirection of old URLs generally costs 60% to 80% of a new site's price, i.e., €2,000 to €8,000 for a brochure site, €6,000 to €12,000 for e-commerce.

The main variable: the current site's state. If it was built with obsolete technology or lacks clean SEO structure, the migration will require more substantial groundwork. A well-executed redesign includes analyzing your analytics to avoid losing already-acquired traffic.

The number of pages and design complexity remain the main cost drivers. A custom site with animations and original illustrations will require far more hours than one based on an adapted premium theme.

Content also plays a massive role. Writing product descriptions, taking professional photos, or producing SEO-optimized copy can account for 20% to 30% of the total budget. Finally, integrations with your POS system, ERP, or online booking tool add custom development billed by the hour.

A €500 brochure site seems tempting. Yet a slow, mobile-unreadable, or outdated design drives away every second visitor before they even see your services. The hidden cost is the margin lost every day your site doesn't convert.

In Brussels, where competition is fierce, a site that doesn't meet user expectations is a direct commercial handicap. Investing in a serious sales tool secures your image and your turnover. The initial extra cost often pays for itself within a few months of additional conversions.

Beyond creation, a website lives on its hosting (€10 to €50 per month for quality hosting), domain name (€15 to €30 per year), and technical updates. For a WordPress or e-commerce site, monthly security and backup maintenance ranges from €60 to €200 per month depending on the site's size and the promised responsiveness.

If you regularly publish content or update products, add an hourly modification package or a support subscription. These costs aren't optional: without them, your site will become slow, vulnerable, and penalised by Google within 18 months.
