When the time comes to build (or rebuild) your website, one debate comes up every time: should you go for WordPress or for custom development? Both have their supporters, and both have genuine strengths. What matters is what fits your situation.

WordPress powers 43% of all websites worldwide. That is no accident. This CMS (content management system) strikes a remarkable balance between accessibility, features and scalability.

The real advantages of WordPress

  • Shorter delivery time: a solid foundation already exists, which reduces development time
  • Manage your own content: you update your text, images and blog without calling in a developer
  • A rich ecosystem: thousands of extensions (plugins) cover 90% of common needs
  • A more affordable initial cost: €1,500 to €4,000 for a well-designed professional website
  • Plenty of providers: if you change agency, another developer can take over your website

The limitations of WordPress

  • Weaker performance out of the box (it needs rigorous optimisation)
  • Greater security exposure if updates are not applied regularly
  • Some very specific features can be complex to build with plugins

A custom website: total freedom, higher budget

Custom development means your website is written from scratch, without a third-party CMS. Every feature is designed and developed specifically for your needs.

When custom development is genuinely necessary

  • You need very specific features that WordPress cannot handle properly (a complex web application, particular business logic, a bespoke ERP or CRM integration)
  • Your performance or security requirements exceed what a standard CMS can offer
  • You have very high traffic that requires an optimised architecture

The drawbacks of custom development for a typical small business

  • A much higher budget: from €5,000, often more than €10,000
  • A longer timeline: 2 to 6 months, compared with 3 to 8 weeks for WordPress
  • Strong technical dependency: if your agency closes, taking over the code can be complicated
  • More expensive updates: every change requires a developer

What most small businesses choose, and why

For 95% of small and medium-sized businesses, a well-built WordPress website is the best option. It gives you a professional, fast, secure and scalable website that you can manage yourself, at a reasonable cost.

The key lies in “well built”. A rushed WordPress site with a generic theme and 40 plugins is indeed slow and fragile. A WordPress site developed by a professional who knows the platform is a solid tool for the next 5 to 10 years.

A quick decision guide

  • Budget under €5,000 → WordPress
  • You want to manage the content yourself → WordPress
  • Timeline under 2 months → WordPress
  • Very specific business features → custom development
  • Web application with complex logic → custom development
  • Exceptionally high traffic → custom development

If in doubt, start with WordPress. You can always migrate to a custom build if your needs change. The reverse (moving from custom development to WordPress) is rarely necessary.
