Omnistack Almost every Belgian SME faces the same question sooner or later: should I build my website with WordPress, or invest in a custom solution? Both work, but they lead to very different results in terms of cost, speed and maintenance.
In this article we compare WordPress with a custom-built (static or Angular) website specifically for the Belgian market, with real fixed prices. That way you can make an informed choice for your business, without jargon and without sales talk.
The difference in a nutshell
WordPress is a content management system (CMS) that powers over 60% of the web. You pick a theme, add plugins and fill in pages. A custom website is code written specifically for your business, usually as a static or Angular site.
That distinction drives everything: with WordPress you pay for convenience and a huge ecosystem; with custom you pay for exactly what your business needs, with control over every line of code. For a contact page, WordPress is overkill. For a site that has to carry your sales, custom matters.
Cost: what do you really pay?
Cost is the first thing entrepreneurs look at, and rightly so. We publish our package prices openly — something most agencies don’t do.
A custom website at Omnistack costs from €599 for a one-pager up to €4,900 for a full webshop, always with a fixed scope and always excluding VAT. With WordPress the upfront build cost is often lower, but once plugins, hosting, security and maintenance are added up, the total cost of ownership grows quickly.
- One-pager: from €599 (custom), delivered in 7 days.
- Starter site: €1,190, the most popular choice for SMEs.
- Business site: €2,490, with more pages and structure.
- Webshop: €4,900, with payment and product management.
- WordPress: low build cost, but plugins (€50–€300/year each) and updates pile up.
Delivery time: weeks instead of months
With a classic agency a WordPress site often takes 4 to 8 weeks, and custom takes even longer. Because we work with a fixed scope and a static build, we deliver a one-pager in 7 days and a full business site in a few weeks.
Why faster? Because there are no theme tweaks, plugin conflicts or endless revision rounds. The scope is fixed, the code is written directly, and the result can be tested right away.
Performance and Core Web Vitals: speed ranks first with Google
Speed is not just nice for your visitor — it’s a ranking factor. Core Web Vitals (LCP, INP, CLS) determine how Google experiences your site. A static or Angular site is served as fixed HTML: almost no load time and an almost always green score.
A WordPress site runs PHP on the server and loads dozens of plugins, themes and jQuery libraries. That often results in red LCP scores, unless you buy and maintain extra caching and optimisation plugins.
Security: less surface, less risk
WordPress is the most attacked platform in the world because it is so popular. Third-party plugins, outdated themes and weak logins are the classic entry points for hackers. You have to keep up with updates yourself (or pay for it).
A static or Angular website has no database and no server-side PHP: there is simply much less to attack. That matters especially for businesses that cannot afford their site going down.
SEO control: no bloat, full control
SEO starts with a clean foundation: semantic HTML, fast loading, no render-blocking scripts, and full control over title tags, meta, canonical, hreflang and structured data (JSON-LD). With custom code we write that control straight in.
With WordPress, SEO depends on plugins like Yoast or Rank Math, on top of a template. That works, but it’s a layer on a slow system — and it rarely matches the performance of a site built without baggage.
Belgian context
For the Belgian market we ship Dutch, French and English versions of every page, with correct hreflang links and a sitemap. That matters whether you serve Flanders, Wallonia or international clients.
Maintenance and scalability
A WordPress site is easy to manage yourself — that’s its big argument. But managing also means updating regularly, making backups and watching security. Someone has to do that work, or the site becomes a risk.
Custom means you scale without effort: adding a section, updating a page or tweaking the layout is fast. For anyone who doesn’t want to spend time on upkeep, we offer a care plan with hosting, updates, backups and monthly reports.

Our verdict
Choose WordPress if you want to publish quickly and yourself on a limited budget, and if your site is mainly informational. Choose custom if your website has to support your business: more conversions, better speed, less security risk and full SEO control.
For most Belgian SMEs, a custom-built site from €599 is the better investment — count the total cost of ownership, not just the purchase price.
Frequently asked questions
Not necessarily. Our custom packages start from €599 (one-pager). With WordPress, the cost of plugins, hosting, security and maintenance stacks up, so the total cost of ownership is often higher.
Yes. You can easily edit texts, images and sections. The admin interface is focused on what you need, without the complexity of a full CMS.
A one-pager ships in 7 days. A full business or webshop website is ready in a few weeks, thanks to a fixed scope and a static build.
Yes, usually significantly. A static or Angular site is served as fixed HTML and almost always scores green on Core Web Vitals, whereas WordPress loads PHP and plugins that add load time.
Not necessarily. SEO starts with a fast, clean base. With custom code we keep full control over title tags, meta, hreflang and structured data, without the extra layer of a plugin.
