A bespoke website or an off-the-shelf solution: how to choose when you run an SME

On mobile, fewer than one in two WordPress sites meet Google’s speed and stability criteria, the Core Web Vitals: 45 per cent, compared with 74 per cent of Wix sites, according to the HTTP Archive’s Web Almanac 2025. In the same year, the WordPress ecosystem recorded 11,334 new security vulnerabilities, 42 per cent more than in 2024. This is not a criticism of the tool itself: it is the price you pay for a website built using a theme, a page builder and plugins, when you ask it to do more than it was designed for.

You run an SME or a mid-market business, and your website needs to be built or redesigned. You have two options: an off-the-shelf solution — WordPress with a theme, Wix, Shopify — or bespoke web development. Neither is inherently better: it all depends on what the website needs to do for your business. Here’s how to tell when it’s time to move away from the first option, and what each approach will actually cost you.

Two approaches, two philosophies

An off-the-shelf solution combines existing building blocks: a content management system, a design template and plugins. It goes live quickly and is inexpensive to set up, but requires constant maintenance: numerous security updates, which can sometimes be costly if one of them breaks a plugin. Hosted platforms, such as Wix or Shopify, relieve you of this maintenance, but restrict you to their features and pricing structures. In both cases, it is your requirements that have to adapt to what the building blocks can do.

Bespoke development works the other way round: you describe what the website needs to do, then it is built. The initial phase takes longer and is more expensive; the website does exactly what you expect, without the burden of features you don’t use.

Seven signs that a ready-made solution is no longer enough

1. Your catalogue exceeds what a theme can display

Technical specifications, filterable features, documents to download for each product: a theme designed for around ten services quickly reaches its limits. ITAFRAN’s multilingual catalogue, built using ArteZya by the company’s digital team, contains hundreds of thousands of product listings.

2. Your customers need a space of their own

Negotiated prices, order history, restricted-access documents, quote requests: this is an extranet, and no theme can properly provide for it.

3. The website must integrate with your software

Stock levels, prices, product listings, contact enquiries to be fed into your management or customer relationship software: every automatic exchange requires custom development. This is Tecalys’s speciality, as it develops business applications.

4. Multiple languages, multiple countries, multiple brands

A multilingual website requires a structure designed specifically for this purpose, and separate search engine optimisation for each language: we explain this in detail in our post on multilingual websites.

5. Extensions pile up

One extension for forms, one for caching, one for SEO, one to fix the previous one… They overlap, eventually contradict one another, every update becomes a risk, and the website slows down.

6. Your customers are searching for you on Google

Google takes into account page speed, heading structure, code quality and mobile display. A generic theme often loads scripts and styles for features you don’t use, and imposes its own structure. The Web Almanac 2025 quantifies this: 60 per cent of WordPress sites use a page builder, and their median mobile performance score is 41 out of 100. A site built for you contains only what each page needs and aligns with your SEO strategy.

7. Your team works around the tool instead of publishing

If updating a page requires ‘tinkering’ with the layout or calling in a contractor, the tool costs more than it’s worth.

The cost over five years, not just the initial quote

Comparing two quotes for website development doesn’t tell the whole story. Look at the five-year picture: subscriptions, annual renewal fees for plugins, a premium theme, hours spent fixing issues after an update breaks a plugin, and the early redesign required when the theme is no longer supported.

A bespoke website costs more in the first year. It often costs less afterwards, because it doesn’t rely on a dozen different providers.

Security: every plugin is another potential entry point

The most widely used solutions are also the most targeted: a vulnerability in a popular extension is exploited across thousands of websites within hours, by bots that do not choose their targets. A bespoke website is not invulnerable, but it exposes less unnecessary code and does not share its vulnerabilities with the rest of the web.

The figures speak for themselves. The core of WordPress is robust, but its ecosystem is not. Patchstack identified 11,334 new vulnerabilities in 2025: around 10,300 in plugins, a thousand in themes, and just six in the core of the software. Nearly half had no patch available at the time they were made public, and for the most frequently targeted vulnerabilities, the median time before the first attack is five hours. The vulnerability database of NIST, the US National Institute of Standards and Technology, lists more than 21,000 vulnerabilities related to WordPress, compared with around sixty for MODX over twenty years, almost all of which were in older versions: only one affects version 3, and this has been fixed since version 3.1.0. The disparity is partly down to prevalence — the most widely used CMS attracts the most attackers — but the lesson remains. That is why we build our websites on MODX using very few extensions.

In both cases, it is updates and monitoring that really provide protection: read about the five most common web security mistakes.

A website that grows with the business

An SME changes: new product ranges, new markets, an additional language, an online service for customers. With an off-the-shelf solution, every change raises the question ‘is there an extension for this?’. With a bespoke solution, the question is “what needs to be added?”, and the architecture is designed to accommodate this.

The middle ground: ArteZya, followed by targeted bespoke development

Between a theme and a full-scale development project, there is a middle ground that we most often take: starting with a solid, open foundation and building upon it to create something unique to you. ArteZya, the headless, no-code CMS we created with Tecalys on MODX, assembles pages from ready-to-use blocks, supports multilingual and multi-site functionality, and allows your teams to publish content without touching the code. The foundation — administration, security, updates — is maintained; when a specific need arises — a catalogue, an extranet, an integration with your software — we add that bespoke development, and only that.

You can get started quickly, without limiting your options: the site grows with your needs rather than having to be rebuilt. We’ve put this to the test on our own site, which was revamped with ArteZya in twelve days, from 30 September to 12 October 2026, including a new design and content.

Your situation in five questions

Answer with a yes or no:

• Should the website generate enquiries or sales, rather than simply showcasing the company?
• Is your content structured: catalogue, product pages, documents, sectors, languages?
• Is Google a significant source of customers?
• Will the website need to be updated within the next two years?
• Does it need to exchange data with your software?

One or two ‘yes’ answers: a well-chosen off-the-shelf solution may be sufficient. Three or more ‘yes’ answers: let’s discuss ArteZya or a bespoke solution.

When an off-the-shelf solution really is enough

A bespoke solution isn’t always the answer. An off-the-shelf solution is a good fit if:

• your website presents the company in just a few pages, without any special features;
• the budget is tight and the website needs to go live within a few weeks;
• you want to trial a new venture before investing;
• someone in your organisation is already familiar with the tool.

In that case, choose a widely used platform, a well-maintained theme, as few extensions as possible, and plan for updates from the outset. We’ll let you know if this applies to you: our aim isn’t to sell more, but to ensure your website serves your business. If this isn’t the case, our bespoke web development service is well worth considering.
