Investing in a website is a crucial step for any Belgian business. Yet between DIY solutions and agency quotes running to several thousand euros, it's easy to get lost.
In 2026, with the acceleration of digital commerce and new e-invoicing standards, the cost of a website can no longer be reduced to simply going live. Here is the complete guide to understanding the real costs, whether you develop your project yourself or with a professional.
1. Creation costs: the initial investment (one-off)
The creation cost depends mainly on who does the work.
The "Do It Yourself" option
If you have the skills to build your website yourself, the creation cost is €0. This is the most cost-effective option for technical profiles or entrepreneurs willing to invest time rather than money.
The showcase website (delegating to a pro)
Ideal for independents and SMEs who want a professional result without dealing with the technical side.
- Average budget (Freelancer): €1,000 to €3,000
- Average budget (Agency): €4,000 to €10,000
- Included: Design, 5–10 pages, contact form and mobile optimisation.
E-commerce & custom websites
- E-commerce: €3,000 to €15,000 (depending on the number of products).
2026 attention point: Integration with the e-invoicing network (mandatory in Belgium for B2B) must be planned from the design stage.
2. Recurring costs: keeping your site alive
A website requires fixed costs to remain accessible. Here, two realities contrast:
The "Optimised" version (the €20 website)
For those who manage their own technical infrastructure intelligently:
- Hosting: €0 (using modern hosting platforms with free plans).
- Domain name: ~€20 / year.
- Maintenance: €0 (since you manage everything yourself).
Total: Exactly €20 / year.
The "Assisted" version (WordPress, Agency, CMS)
If you go through classic tools or a maintenance contract:
- Domain name: ~€20 / year.
- Professional hosting: €80 to €300 / year.
- Technical maintenance: €300 to €1,200 / year (updates, security, backups).
Total: €400 to €1,500 / year.
3. Why do prices vary so much?
Several factors influence the final amount of your bill:
- Time vs money: Developing yourself is free in cash but expensive in time. An agency sells speed and business expertise.
- Multilingual: In Belgium, a FR/NL/EN site requires a more complex structure. Plan for an additional 20% to 30%.
- SEO: Having a website is one thing; being found on Google is another. Visibility work is often a separate budget entirely.
Conclusion: An investment, not an expense
In 2026, having a professional website in Belgium suits all budgets:
- If you're resourceful: Your website can cost you just €20 / year. This is the ultimate solution for keeping full control of your costs.
- If you delegate: Plan an initial budget of around €2,500, then €500 / year for maintenance.
What matters most is not paying the lowest price, but remaining the owner of your domain name and your files.
