A “free” site built on an online builder, a pre-made WordPress theme or a custom build: the right choice mostly depends on your business’s horizon. In short: free tools are fine for validating an idea, a pre-made theme can get you by on a tight budget, and custom becomes the most cost-effective choice as soon as your site plays a real role in your sales — because the real bill is calculated over three to five years, not at launch.
The “free” site: perfect for testing, risky for building
Platforms like Wix, Squarespace or hosting providers’ free plans let you get something online quickly, with no investment. To validate a project or put up a temporary business card, that’s legitimate. The limits arrive fast: monthly subscriptions that pile up, capped customization, SEO that’s harder to work on in depth, and above all, you don’t really own your site. The day you want to migrate, you often start over from scratch.
The pre-made theme: cheap at first, dependent afterwards
On WordPress, you can install a purchased theme (often bundled with a page builder) and customize it. The initial investment is lower and the result can look presentable quickly. But our experience — we regularly repair this kind of site — reveals three recurring problems:
- A sense of déjà vu. Popular themes are used on hundreds of thousands of sites. Your image ends up looking like everyone else’s.
- Costly modifications. As soon as you step outside the options the theme’s author planned for, a simple adjustment can take two to ten times longer than in well-managed code — when it’s possible at all.
- A chain of dependencies. Your site depends on the theme, which depends on a page builder, which depends on plugins. One incompatible update — or an author who abandons their product — and you inherit a problem nobody chose. That’s precisely the moment when the “economical” option becomes more expensive than custom.
Custom: more expensive up front, more solid over time
A custom site starts from your visual identity and your real needs, not from a template to contort. The design belongs to you, the code is lightweight because it contains only what you need — which directly helps speed and SEO — and every future evolution happens in a controlled environment, with no nasty compatibility surprises.
And custom in 2026 is not what it was in 2018. With WordPress’s native block editor (Gutenberg), a well-built custom theme lets you edit your own text, images and pages yourself, without depending on a third-party page builder or going back to your agency for every comma. You get the best of both worlds: a solid, unique foundation, and day-to-day autonomy. It’s the approach we favour in our website design projects.
How to decide, concretely
Ask yourself three honest questions:
- What role does the site play in my sales? If it generates calls, quote requests or orders, it deserves a solid foundation.
- What is my horizon? A site easily lives five years or more. Compare the options over that span, maintenance and modifications included, not just at launch.
- Who will maintain it? Whatever the option, a WordPress site needs updates and monitoring. A pre-made theme generally needs more of them.
If you already have a site built on a pre-made theme that’s giving you headaches, not everything has to go in the bin: a redesign or targeted optimization often makes it possible to recover the content and start over on a healthy foundation. And if you’re weighing the options for a new project, talk to us about it: we’ll tell you frankly which one fits your situation — including when custom isn’t justified.
