WEBSITE DESIGN

A website that explains your offer
and prepares visitors to get in touch.

Does your website no longer reflect your business or leave visitors without answers? We scope the content, identity, imagery and journey, then build a version to review before publication. Deliverables and checks are set out in the quote.

Real websites, different user journeys.

Targeted improvements to your existing website

Conversion Sprint

One contact, quote request or booking journey. Two agreed improvements across up to three pages in one language, with testing and a handover. One-off fee: €1,500 excluding VAT, subject to feasibility confirmation.

The full CRO programme, a redesign and the creation of complex new features each have their own scope.

Prepare my Sprint

Creating a useful website means connecting an offer, its audiences and measurable actions through an accessible, maintainable architecture. The right format depends on the content, features and team: a landing page, business website, e-commerce store or custom development. This can then be supported by performance work, maintenance and GDPR scoping where the project requires it.

  • Divi Page builder

  • Wix Takeover, SEO or migration
  • Squarespace Takeover, SEO or migration
  • Shopify Store, theme and SEO

Frequently asked questions

What clients always ask.

To plan your project’s funding, read our guide to the Brussels digitalisation grant: eligibility, timing and what to prepare before you start.

How much does a professional website cost in Brussels?
A premium business website starts at €4,500 excluding VAT, and an e-commerce store at €8,500 excluding VAT. The quotation depends on the number of pages, custom features, multilingual content and third-party integrations (CRM, ERP, payments). No opaque packages: you receive an itemised quotation after the free audit. If your current website needs replacing, our advice on planning a successful website redesign will help you define the project.
How long does it take to deliver a website?
The schedule depends on the number of pages, content, integrations and approvals. The proposal sets out milestones for scoping, wireframes, design, development, acceptance testing and launch. A timeline is only confirmed once the scope has been inventoried.
Which CMS do you recommend: WordPress, Astro or something else?
It depends on the project. WordPress makes sense when a team wants to manage a rich publishing ecosystem. Astro suits content websites where lightweight static rendering is appropriate. Custom development addresses specific business requirements. We document the choice instead of applying a generic percentage. Whatever the CMS, the interface is based on a consistent design system.
Can you take over or fix a WordPress, Wix, Squarespace or Shopify website?
Yes. Everything starts with a diagnosis: access, backups, plugins, speed, security and SEO. Depending on the state of the website, we fix what is already there, take over its maintenance or prepare a migration to a better-suited solution, with redirects and SEO monitoring. Webflow, Joomla, Drupal and PrestaShop are also assessed case by case. The scope is confirmed before any work begins.
Will I really own the website?
Rights to content, data, access, code and components are detailed in the proposal and contract. Client-supplied materials, third-party licences and Kanexio components may be subject to different terms. The planned handover is documented before work begins.
What happens after delivery?
The acceptance period, included corrections, maintenance, backups and response times are set out in the proposal. Ongoing maintenance or on-demand support can then be arranged according to the technology stack.
What does the PageSpeed Insights 95+ guarantee cover?
Kanexio guarantees a PageSpeed Insights Performance score of 95 or above at delivery for the pages, version and device type specified in the quotation. The check is dated and documented. The guarantee does not cover CrUX field data, rankings, conversions or subsequent changes made by a third party. This guarantee applies only if included in the quotation.
