Over 15 years of consulting, I’ve seen this story play out dozens of times. A business hires a talented developer. The developer suggests building a custom CMS — “it’ll be perfectly tailored to your needs.” The client agrees. Twelve months later, the site is live. Two years after that, the developer is gone. Nobody else understands the code. The system slowly rots.
WordPress doesn’t make headlines. It’s not exciting. But for most business websites, it’s still the right choice — and understanding why requires looking honestly at the alternative.
The Custom CMS Trap
The appeal of a custom-built system is real. You get exactly what you need, no unnecessary complexity, no licensing constraints. In theory.
In practice, custom CMS projects fail businesses for a few consistent reasons.
The developer who built it holds all the keys. A custom system is, by definition, something only its creator fully understands. When that person moves on — and they will move on, whether to a new job, a new country, or just a new client — you’re left with a system that nobody can maintain. Finding someone to take over isn’t just difficult; it’s expensive, and there’s no guarantee they’ll agree to touch someone else’s undocumented code.
The cost of ownership compounds over time. Building the system is one cost. But software doesn’t stand still. Hosting environments change. Security vulnerabilities appear. Browser standards evolve. Integrations break. With a custom system, every one of these issues requires paid developer time, and there’s no community or ecosystem to absorb the cost. I’ve seen businesses spend more on maintenance over three years than they spent on the original build.
Updates become a crisis. A standard business site needs updates: new pages, changed contact details, revised service descriptions, a new team photo. With a custom CMS, every change that isn’t a simple text edit requires developer involvement. If your developer charges 150 CHF per hour and you need four small updates per month, that’s a meaningful recurring cost — for tasks that should take minutes.
Why WordPress Works
WordPress powers around 43% of all websites on the internet. That number is relevant not because popularity implies quality, but because it implies an ecosystem. When something is that widely used, problems have already been solved, documentation exists, and thousands of developers know how to work with it.
Ownership transfer is straightforward. If your current developer stops working with you, finding a replacement who knows WordPress is trivial. The knowledge is commoditised. You’re not locked into a single person or agency.
Your team can manage it. WordPress’s admin interface is designed for non-technical users. Uploading a blog post, updating a page, changing a product description — these are tasks a marketing manager or office administrator can handle without touching code. That’s not true of most custom systems.
Security is handled by a large community. WordPress does have security vulnerabilities — this is true of any software with hundreds of millions of installations. But the security team is large, patches arrive quickly, and the ecosystem of managed hosting providers (Kinsta, WP Engine, Cloudflare) handles most of this automatically. The relevant comparison isn’t “WordPress vs. a perfect system.” It’s “WordPress vs. a custom system maintained by one developer who may or may not patch it.”
The plugin ecosystem solves real problems cheaply — and fast. WordPress has over 60,000 plugins in its official directory. That number matters because it means almost any business requirement already has a tested, maintained solution.
Need an online booking system? WooBookings or Amelia. E-commerce? WooCommerce powers millions of stores. Multilingual site? WPML. Cookie consent for Swiss and EU compliance? A five-minute install. SEO audit tools, contact forms, live chat, appointment scheduling, PDF invoices, membership areas, event calendars — all available, most for free or a small annual licence.
For clients, this translates directly into money saved. A custom booking integration might cost 3,000–8,000 CHF to build and test. The WordPress equivalent costs 89 CHF per year and was used by 200,000 sites before you ever installed it. The bugs were found by someone else. The edge cases were handled by someone else. You’re paying for a solution, not for development time.
The Security Argument, Honestly
WordPress gets criticised for security, and not without reason. Outdated plugins, abandoned themes, and poor hosting choices account for the majority of WordPress compromises. But this is an argument for using WordPress correctly, not for abandoning it.
A properly configured WordPress site — with automatic updates enabled, a reputable hosting provider, an SSL certificate, and active plugin maintenance — is secure enough for any standard business website. The businesses I’ve seen get compromised were running outdated installations on cheap shared hosting, with plugins last updated in 2019.
Security is a practice, not a platform choice.
When Custom Development Makes Sense
There are cases where WordPress genuinely isn’t the right tool. If you’re building a marketplace, a complex booking platform with custom business logic, a SaaS product, or something with deep integrations into proprietary internal systems — then yes, a custom build may be necessary.
But a company website with a services page, a team section, a blog, and a contact form? That’s not one of those cases.
The Website Builder Trap
There’s a third option that often gets ignored in this conversation: platforms like Wix, Squarespace, Webflow, or Jimdo. They’re heavily marketed, easy to start with, and look appealing when you’re trying to avoid both custom development and WordPress’s learning curve.
But they come with a set of problems that only become visible after you’ve committed to them.
You’re renting, not owning. Everything — your content, your design, your domain configuration, your SEO history — lives on someone else’s platform. The moment you stop paying, your site disappears. And prices rarely stay fixed: Wix has raised its plans multiple times. What costs 20 CHF today may cost 50 CHF in three years, and you have no leverage because switching means rebuilding from scratch.
Export is a dead end. Try to leave Wix or Squarespace and you’ll quickly discover that your content doesn’t export cleanly. There’s no standard migration path. Pages, blog posts, custom layouts — you lose most of it. You’re not just changing hosts; you’re starting over. This is by design.
SEO is crippled by platform limitations. Many builders generate bloated HTML, append unnecessary URL structures, load excessive JavaScript, or limit your control over technical SEO. On Wix, you can’t fully control your robots.txt. On Squarespace, canonical tags and structured data customisation are restricted. For a business trying to rank in a competitive local market, these limitations have real consequences.
You hit a ceiling fast. The moment you need something that isn’t in the template library — a custom booking flow, a specific integration, a unique layout — you’re either stuck or paying for expensive premium add-ons. The initial simplicity is real. The long-term flexibility is not.
Your data belongs to the platform. Analytics, form submissions, customer data — all of it passes through infrastructure you don’t control and can’t audit. For businesses subject to Swiss or EU data protection law, this creates compliance exposure that most platform users never think about until there’s a problem.
Website builders make sense for a personal landing page, a temporary campaign site, or a freelancer who needs something online in an afternoon. For a business that plans to grow, invests in SEO, or needs to own its infrastructure — they’re a subscription that gets more expensive over time while quietly limiting what you can do.
What I Tell Clients
When a client comes to me asking whether to rebuild their website on a custom platform, I ask two questions: who will maintain this in three years, and what problem does custom development solve that WordPress cannot?
In most cases, the answer to the first question is unclear, and the answer to the second is “nothing specific.” At that point, the custom build is a risk, not an advantage.
WordPress isn’t perfect. It’s not glamorous. But it’s reliable, widely understood, maintainable by non-developers, and supported by an ecosystem that will outlast any individual developer relationship.
For most business websites, that’s exactly what you need.
