The prices are wildly different. The outcomes over three years are even more different. This is not about which option is cheapest. It is about which one makes you money.
When a business owner starts looking for a new website, they typically end up comparing three options: build it themselves on Wix or Squarespace, buy a WordPress theme and set it up, or commission a custom-built site from an agency. The prices are wildly different. The outcomes, over three years, are even more different.
This is not a post about which option is cheapest. It is about which one makes you money.
Website builders are genuinely good at one thing: getting something live quickly without a developer. If you are a freelancer, a sole trader testing a business idea, or someone who needs a simple five-page site and has no budget, they are a reasonable starting point.
The problems surface as you grow. Website builders generate bloated HTML that is difficult for Google to crawl efficiently. You are limited to the templates and features the platform provides. If you need a custom booking flow, a membership area, a specific integration, or anything beyond what the platform offers out of the box, you either cannot do it or you pay for an app that partially does it.
The recurring costs also compound. Wix and Squarespace charge monthly fees that increase as you add features. By year three, a business running a Wix site with e-commerce and a few add-ons can easily be spending more than the cost of a professional website build, with less to show for it in terms of performance and search visibility.
WordPress powers around 43% of the web, which tells you it works. The platform itself is solid. The problem is almost never WordPress. The problem is the way most people use it.
A business that buys a premium theme from ThemeForest and installs a page builder like Elementor or Divi ends up with a site that loads 12 JavaScript files before the hero image appears. Those themes are built to impress in the preview, not to perform in production. They include hundreds of features you will never use, all of which add weight to every page load.
Security is another consistent issue. Off-the-shelf themes and their associated plugins are high-value targets for attacks precisely because they are so widely used. A vulnerability in a popular plugin becomes a vulnerability on every site running it. Keeping plugins updated is manageable if you are technical. If you are not, it is a maintenance risk that builds quietly over time.
The SEO situation is better than Wix but still limited. Heavy themes with generic markup do not give you the fine-grained control over structured data, semantic HTML, and performance that a custom build provides.
A custom site costs more upfront. That is the honest answer, and any agency that tells you otherwise is selling you something. The question is not whether the upfront cost is higher. It is whether the three-year total cost of ownership, including lost revenue from poor performance, is higher or lower.
A custom build starts from your goals, not from a template. The code that ships is only the code your site needs. No unused features, no plugin stack generating security vulnerabilities, no performance overhead from somebody else's design choices. Core Web Vitals scores are higher. Google rankings follow. And because the site is built specifically for your business, the conversion structure reflects how your actual customers make decisions, not how a generic template assumes they do.
At KadoshDev, we build custom WordPress themes and bespoke React sites depending on what the project requires. Our Sanne Consultancy build is a custom WordPress theme with 35 purpose-built Gutenberg blocks, giving the client full editorial control without a single third-party page builder involved. Our Excel Kids Academy site is a custom-coded build designed specifically around how parents, donors and volunteers engage with the organisation.
| Consideration | Wix / Squarespace | WordPress + Theme | Custom Build |
|---|---|---|---|

| Ongoing monthly fees | High and grows | Hosting + plugins | Hosting only |
| SEO performance | Limited | Moderate | Strong |
| Page speed | Poor to moderate | Poor to moderate | Strong |
| Security risk | Platform-managed | Higher (plugins) | Low |
| Custom functionality | Very limited | Plugin-dependent | Unlimited |
| You own the code | No | Yes | Yes |
If you are just starting out and need something live while you validate an idea, a website builder is fine. Do not spend serious money on a website for a business you are not yet sure about.
If you have an established business, a defined customer base, and a website that is supposed to generate leads or sales, the calculus changes. The money you save on a cheap build is typically recovered within the first year by lost search visibility, slower load times, and a design that does not convert as well as it should.
The businesses that get the best return from their websites treat them as investments, not expenses. If you want to talk through what the right approach looks like for your specific situation, we are happy to have that conversation before you commit to anything.
