For a Belgian SME or self-employed professional, a professional showcase website takes 4 to 10 weeks to build. Four weeks when the copy and the photos are ready on the day the project starts, ten weeks (sometimes more) when the content still has to be written, when several people sign off, or when the site has to exist in French and in Dutch. The technical side is almost never the limiting factor.
A website remains the basic equipment of a business. According to Eurostat, 79.01 % of enterprises in the European Union had a website in 2025, a figure that drops to 76.66 % among organisations with 10 to 49 people against 95.65 % among large ones. In Belgium, DNS Belgium recorded 207,776 new .be domain names in 2025, for a base of 1,701,999 active domains at the end of 2025.
When you run an SME, the question is not whether the site will arrive, but when. A vague deadline lets the project drag on for six months. Here is the real calendar, phase by phase, with what depends on the agency and what depends on you.
The real timeline by scope
A showcase site of 5 to 8 pages
The most common format among Belgian SMEs and independents: home, services, about, references, contact. Count 4 to 6 weeks when the content already exists, 8 weeks when it has to be produced. That timeline covers scoping, design, build, legal compliance and corrections.
A larger site or an online shop
As soon as you add a catalogue, payments, a customer area or a connection to your management software, the project changes nature: count 8 to 14 weeks. It is not the number of pages that stretches the planning, it is the number of cases to test: stock, delivery, VAT, returns, transactional emails.
The Belgian multilingual case
A French and Dutch site does not double the timeline, it generally adds 1 to 2 weeks: translation, review by a native speaker, URL structure and markup per language. The trap is not the translation itself, it is the review, which always lands at the end of the project.
What really slows a project down
The content
A web project almost never stalls on the technology, it stalls on the content. Introduction copy, service descriptions, team photos, client references: all of that calls for decisions, and those decisions belong to the business owner. A site whose copy is ready at signature is often delivered in half the time.
The sign-offs
Three people approving means three times more back and forth. Appoint a single point of contact who decides, consulting internally before answering if needed. It is the adjustment that saves the most time, and it costs nothing.
The obligations to build in
Legal notices, consent banner, privacy policy and accessibility, mandatory in the European Union since 28 June 2025 for part of the activities: these elements are prepared during the project, not the day before going live. Handling them early avoids a week lost just before launch.

The calendar week by week
Here is the typical run of a website design project for a Belgian SME, in the 6-week version:
Week 1, scoping: objectives, site structure, competitors, target keywords, gathering access credentials and existing content.
Week 2, design: mock-up of the homepage and of an inner page template, approval of the visual direction.
Weeks 3 and 4, build: page construction, mobile versions, forms, analytics, legal compliance.
Week 5, content and proofing: integration of the final copy, photos, optimisation of titles and descriptions.
Week 6, testing and go-live: tests on mobile and desktop, speed, redirects in case of a rebuild, domain name switch.
Two points of attention. Content appears in week 5, but it is prepared from week 1. And if the site replaces an existing one, add a step for the redirect plan, detailed in our checklist for a rebuild without losing rankings.
After going live: the Google timeline
Putting a site online takes a few weeks, making it exist in Google takes a few months. Indexing first: according to Google Search Console help, the delay between a page being crawled and being indexed runs from a day or two to a few weeks, and Google recommends waiting at least a week after submitting a sitemap before worrying.
Ranking, next, is another time scale. According to an Ahrefs study published in May 2025, only 6.11 % of newly created pages reach the top 10 within a year, and 72.9 % of the pages sitting in the top 10 are more than three years old. The average age of a page ranking first is five years.
A site delivered in six weeks therefore does not produce enquiries in the seventh. Plan for three to six months before organic search picks up on local queries with little competition, and support the start with an advertising campaign if you need volume straight away.
Frequently asked questions
Can you have a site in one week?
Yes, on a very narrow scope: a single page, an existing template, your copy and photos delivered on day one. Useful for testing an offer, provided you accept that it will need reworking afterwards.
Why do two agencies quote very different timelines?
Because they are not counting the same thing: some quote the build time alone, others the complete project, content and compliance included. Ask what the planning includes and what it expects from you.
Who writes the copy for the site?
Two options: you write it (fastest if you already know what to say) or the agency writes it from interviews (two to three weeks more, but better calibrated for search). The bad scenario is the third one: nobody takes it on, and the project stops.
Should you wait until everything is perfect before going live?
No. A complete, correct site online beats a perfect site postponed by three months: indexing starts at go-live, and lost time is not recovered. Adjustments come afterwards, based on real data.

Priority action plan
Set the go-live date before anything else: a project without a deadline slips, every time.
Gather your content in week 1: copy, logo in vector format, photos, client references, access to the domain name.
Appoint a single decision-maker: one person approves the design and the copy, the others are consulted beforehand.
Handle compliance during the project: legal notices, cookies, accessibility, rather than the day before launch.
Plan what comes next: analytics in place on day one, first visibility review at three months, regular content after that.
A website schedule is not a sales promise, it is a mutual commitment. The agency holds its design and build deadlines, you hold those for content and approval. The projects that ship in six weeks are not the technically simplest ones, they are the ones where everyone knew exactly what to deliver and when. The opening decisions count as much as the planning: they are listed in our article on the questions to settle before launching a site, and the budgets in our comparison of prices in Belgium.
A schedule to hold for your next site? We frame the project and the go-live date from the first conversation: website design for Belgian SMEs.
