Custom WordPress Development Services

Elementor, Divi and WPBakery let anyone drag a page together, and for a quick test that is fine. The cost appears later: every page loads the builder’s scripts and styles, the HTML is ten layers of nested containers, and a layout tweak on one page can quietly break another. Many slow WordPress sites I see are slow for exactly this reason.

My custom WordPress development services take a different route. The site gets either its own theme or a light block theme on top of the native WordPress editor, with blocks designed for your content: a service card, a price table, a team member, a case study. Editors pick a block and fill in text and images; the layout, spacing and colors stay as designed. The result is less code on every page, faster loading and an admin that does not need a manual.

Custom WordPress theme development

A custom theme contains only what your site uses: templates for your page types, your blocks, your fonts and colors. There is no demo content to delete, no options panel with four hundred settings and no dependency on a theme vendor who may stop releasing updates. If you already have a design in Figma, I build the theme from it; if not, the design is part of the price.

Custom WordPress plugin development

When a site needs something no ready plugin does well — a price calculator, a booking request that goes to your CRM, a custom content type for projects or properties, an import from an external system — I write it as a small plugin of its own. That keeps the feature separate from the theme, so a redesign later does not delete it. Connections to outside systems are described in more detail on the CMS integration and API work page.

Speed on a phone

Images are served in modern formats and sized for the screen, scripts load only on pages that use them, and caching is set up on the server or with one plugin. The target is a Largest Contentful Paint under 2.5 seconds on mobile, the level Google rates as good, and it is checked before launch, not promised.

Security and updates

Most WordPress hacks come through outdated or abandoned plugins. Fewer plugins means fewer doors; the ones that stay are maintained and widely used. Admin accounts get strong passwords and two-factor login, backups run daily and are stored outside the server, and updates are tested before they reach the live site.

WordPress maintenance after launch

After launch you can keep the site yourself or hand updates, backups and small changes to me. The plans are described on the website maintenance services page.

If your WordPress site takes five seconds to open, throws errors after every update or nobody dares to touch it, the first step is to find out why. Sometimes one heavy plugin or uncompressed images explain most of the problem and a few fixes are enough; sometimes the theme and builder are the cause and a rebuild is cheaper than patching. A website performance and code audit answers that question with numbers before you spend money on either path.

Felgilab, a wheel-renovation workshop in Warsaw, is an example of a WordPress rebuild: the new site gives each service its own page and shows prices, so customers can check them before calling. One-off fixes on an existing site cost 250–700 €; a rebuild is priced like a new site.

ScanM2, a 3D laser scanning and BIM company, had a site on a no-code builder that brought no leads for two years. I rebuilt it on WordPress, kept the design the team liked and set it up in English, Polish and German. After the move organic traffic grew 29 times and leads now come every week. The move worked because every old address was mapped and redirected before launch, and titles and structured data were carried over.

The same care applies in the other direction: some companies outgrow WordPress and move to Next.js or another platform. Moves both ways are described on the website platform migration page.

WooCommerce for a product catalog and simple ordering

If you need to show products with prices, filters and an order or inquiry form, WooCommerce on top of your WordPress site handles that well. I set it up as a catalog with simple ordering — product pages, categories, a short checkout or a request form — built in the same lean theme as the rest of the site.

White label WordPress development for agencies

Marketing and design agencies sometimes need a developer to build a WordPress site from their design under their brand. I can take the build from Figma to launch, work in your project tools and invoice your agency, while you keep the relationship with your client.

Enterprise WordPress development for larger company sites

For larger sites the questions change: several editors with different roles, many language versions, a staging copy for testing, integrations with CRM or marketing tools, and a clear update process. These are built into the project from the start rather than added when something breaks.

WordPress is a content management system, and it still runs a large share of the web — W3Techs counts it on roughly four in ten websites. It is not going away. But some teams do leave it, usually for one of these reasons:

• the site became slow and fragile after years of added plugins and page builder layouts
• maintenance takes too much time: plugin updates, conflicts, security warnings
• a development team prefers working in JavaScript frameworks and a headless CMS
• the public dispute in 2024 between Automattic and the host WP Engine made some owners worry about the platform’s direction

Most of these problems come from how a site was built, not from WordPress itself. A lean WordPress site with a custom theme and few plugins avoids the first two. The third is a real reason to choose something else.

WordPress fits when your team wants to edit everything in a familiar admin, you need a catalog or a blog with many authors, and the budget favors a site that a large pool of developers can maintain. Next.js fits when speed and full control over the code matter most, the site is multilingual and content-heavy, or it has to work closely with other apps. A headless setup, with WordPress as the editor and Next.js on the front, sits between the two.

I build both, so the advice does not depend on what I sell. The Next.js side is described on the Next.js development services page.

ChatGPT, Perplexity and Google AI Overviews now answer questions that used to send people to search results, and they recommend companies they can read and check. WordPress sites often hide facts inside sliders, images and builder markup. I build them so the important facts — services, prices, areas, languages, contact details — are plain HTML text, with structured data for the business, its services, FAQs and articles.

The robots.txt file is set deliberately: search crawlers such as OAI-SearchBot and PerplexityBot are allowed in, and you decide separately whether training crawlers like GPTBot and Google-Extended may use your content. Blocking Google-Extended does not remove a site from AI Overviews, which rely on the normal Googlebot.

Getting mentioned in AI answers is ongoing work, described on the AI SEO and GEO optimization page. If you need SEO advice for an existing WordPress site rather than a build, see the SEO consultant page.

My prices are published on the pricing page, and design is included in both website prices:

• A custom WordPress website — home page, service pages, about, contact, forms, on a lean theme: 700–1,400 €.
• A larger WordPress website with custom blocks, plugin features, integrations and language versions: from 2,000 €.
• One-off fixes on an existing WordPress site, such as speed, errors or a new feature: 250–700 €.

The price depends mostly on the number of page types, custom features and languages, not on the number of pages: twenty service pages built from the same template cost little more than five. You pay hosting and plugin licenses, if any, directly to the providers, and the site, theme and code are yours.

How a WordPress project runs

1. Brief: what the site should do, who it is for, and what you already have.
2. Page list and a fixed price; any later change of scope is priced before it is made.
3. Design of the home page and one inner page, phone first.
4. Theme, blocks and content; you test the admin on a staging copy.
5. Launch with redirects, analytics and Search Console, plus a short editing guide.
