Custom WordPress websites: from blog to enterprise platform
Getting a WordPress website built is the most pragmatic choice for many organisations: a proven CMS with a huge ecosystem, manageable by editors without a technical background, and extendable to complex functionality. We build WordPress solutions that go beyond standard themes, from custom theme development and plugin building to WooCommerce webshops and headless WordPress architectures.
WordPress as the foundation for business websites
WordPress powers a substantial share of the world wide web, and that is no accident. The platform offers a mature, well-documented foundation with thousands of available plugins, an active developer community and a back end that editors and marketers can operate independently. At the same time, WordPress is flexible enough to serve as the foundation for complex digital products, provided it is configured correctly and extended properly.
Organisations often run into the gap between WordPress's standard capabilities and the specific needs of their business. A generic theme rarely fits a brand identity perfectly. Off-the-shelf plugins don't always offer the exact workflow an organisation requires. And larger sites or shops raise performance and security challenges that call for specialist expertise.
What we offer
We use WordPress as a platform tailored from start to finish to your organisation. That means deliberate decisions on theme architecture, targeted plugin selection or development, and a hosting and deployment setup that matches your scaling requirements. Our work connects to your broader CMS strategy and, where needed, we combine WordPress with other technologies from our services.
- Custom theme development based on your design
- Custom post types, taxonomies and field groups (ACF/Meta Box)
- WordPress plugin development for unique functionality
- REST API and GraphQL integrations
- Multisite configurations for multiple brands or locations
- Performance optimisation (caching, CDN, database optimisation)
Which organisations this suits
WordPress is a suitable choice for a wide range of organisations. Think of businesses that want a professional marketing website that is easy to manage in-house, media companies and publishers with high publication volumes, organisations combining an information site with a webshop, and businesses that want to scale or modernise an existing WordPress platform.
From theme customisation to fully bespoke development
Not every project requires the same level of customisation. We tailor our approach to your specific situation: sometimes a well-considered child theme on a solid foundation is enough; sometimes a fully custom theme is the only way to realise your design vision and functional requirements. We always think about maintainability and long-term development.
Child themes and theme adjustments
If a strong parent theme is already available that suits your technical requirements, we build a child theme that translates your brand identity. We adjust CSS, override templates and extend functionality without modifying the parent theme. Updates to the parent theme can thus be rolled out safely.
- CSS and JavaScript adjustments
- Template overrides for specific page types
- Brand identity implementation
- Preserving updatability
Custom WordPress theme
A theme built entirely from scratch offers maximum control over performance, structure and design. There's no unnecessary code from a parent theme and no constraints from someone else's architectural decisions. We build from the Block Editor (Gutenberg) or via a custom template hierarchy, depending on your content management requirements.
- Built from your design (Figma, XD or sketch)
- Gutenberg blocks or classic editor support
- Optimised page structure for SEO
- No superfluous code or dependencies
Custom plugins and extensions
If the functionality you need isn't available through existing plugins, or if existing plugins include too much you don't want, we develop custom plugins. These can range from a simple shortcode to a full-fledged module with its own database tables, REST endpoints and an admin screen.
- WordPress plugin development following Coding Standards
- Custom REST API endpoints
- Integrations with external systems
- Custom admin screen in the WordPress dashboard
Block Editor (Gutenberg) and Full Site Editing
With the Block Editor, WordPress has fundamentally changed the way content is built. We create custom Gutenberg blocks that enable your editorial team to produce rich, consistent content without needing to touch the code. Through Full Site Editing, you can also manage the entire page layout, including the header and footer, from the WordPress admin. We ensure that the blocks we build integrate seamlessly with your design system. Related: our custom CMS website development service and our work on web applications.
WooCommerce: your online shop on WordPress
WooCommerce is the most widely used e-commerce platform in the world and turns your WordPress site into a fully functional online shop. Compared with SaaS platforms, its advantage is that you retain full control over your data, your checkout flow and your integrations. The drawback is that responsibility for hosting, security and maintenance rests with you. We take that responsibility off your hands.
What we build with WooCommerce
We build WooCommerce setups tailored to your range, logistics and customer journey. That means carefully structured product catalogues, an optimised checkout, integrations with your accounting or ERP system, and connections to payment providers and shipping services. For larger shops we also focus on scalability: database optimisation, caching and a hosting setup that can handle peak loads.
- Bespoke WooCommerce installation and configuration
- Custom checkout and product pages
- Integration with payment providers (Mollie, Stripe, etc.)
- Integration with accounting software or ERP via API integrations
- Setting up shipping rules, taxes and discount codes
- Subscriptions and recurring payments
When WooCommerce, and when something else?
WooCommerce is an excellent choice if your organisation already works with WordPress and you want to add an online shop, if you need a strong content marketing presence alongside your shop, or if your catalogue is relatively straightforward. For very large catalogues (tens of thousands of SKUs), complex B2B ordering or extreme peak loads, we also consider alternatives such as a headless e-commerce setup or a dedicated platform. We always give you an honest assessment of which approach suits your situation.
See also our page on e-commerce development for a broader overview, or read more about headless commerce if performance and scalability are top priorities.
"WooCommerce gives you full control over data and checkout, but that control also comes with technical responsibility."
Headless WordPress: a modern architecture for speed
In a traditional WordPress setup, WordPress handles both content management and front-end presentation. In headless WordPress, those two layers are decoupled: WordPress manages the content and makes it available via an API, while the front end is built with a modern JavaScript framework. This pattern is gaining ground because it offers performance, flexibility and scalability benefits that the classic WordPress setup cannot provide.
How headless WordPress works
WordPress runs on the server as the CMS. Content queries are handled via the built-in REST API or via WPGraphQL (a GraphQL layer on top of WordPress). The front end, built in Next.js, Nuxt or a similar framework, fetches the data and renders the pages. Static pages are generated at publication (Static Site Generation) or on request (Server-Side Rendering), depending on the caching strategy.
The result is a website that combines the content management familiarity of WordPress with the performance and flexibility of a modern JavaScript stack. For editors, little changes: they continue to work in the familiar WordPress dashboard. The technical benefits become visible in load times, Core Web Vitals scores and the possibilities for Progressive Web App functionality.
When to choose headless?
Headless WordPress is particularly valuable when loading speed and Core Web Vitals scores are strategically important, when you want to use the front end as the basis for a mobile app (content reuse), when you face high peak loads where a CDN-cached front end scales better, or when you want to use specific front-end technology that does not fit the classic WordPress template architecture.
- Next.js or Nuxt as the front-end framework
- WPGraphQL for efficient data queries
- Incremental Static Regeneration for real-time content
- CDN deployment for global performance
- WordPress as a trusted content management layer
- Can be connected to our API integration services
Headless WordPress in practice
A headless setup also introduces complexity: preview functionality requires additional configuration, deployment pipelines are more extensive, and the front end needs its own hosting environment alongside WordPress. We guide you through these trade-offs and build a setup that suits your technical team and operational preferences. We also look at related solutions, such as a fully headless commerce platform, if that fits your e-commerce ambitions.
Maintenance, security and ongoing development
Getting a WordPress website built is the start, not the end point. WordPress installations that aren't maintained pose a security risk: outdated plugins are the most common attack vector. We offer ongoing maintenance so your site stays stable, secure and up to date.
Security management
WordPress is a popular target for attacks. We minimise the attack surface through careful plugin selection, strong authentication settings, a Web Application Firewall and regular security scans. Read more about our approach in our information security policy.
- Automatic security updates
- WAF configuration
- Two-factor authentication for admins
- Malware scanning
- Limiting of login attempts
Ongoing maintenance
Updates to the WordPress core, theme and plugins are tested in a staging environment before they go live. We keep backups and check that the site continues to function correctly after each update. Minor bugs or requests are handled quickly.
- Controlled plugin and core updates
- Staging environment for testing purposes
- Automated daily backups
- Uptime monitoring
- Rapid resolution of incidents
Scaling and expanding
Your digital product grows along with your organisation. We actively think along about new functionality, integrations with other systems and the transition to a more scalable architecture should your WordPress site reach its limits. Consider extending it with an app through our software development services.
- New functionality in sprints
- Performance audits and optimisation
- Database optimisation as you grow
- Migration to headless when scalability requires it
- Integrations with new systems

Hosting and infrastructure
The performance of a WordPress site depends heavily on your choice of hosting. We advise on and configure managed WordPress hosting (Kinsta, WP Engine, Flywheel) for projects where ease of management is the priority, or dedicated VPS/cloud hosting (DigitalOcean, AWS, Hetzner) for projects with specific scaling or configuration requirements. A staging environment is standard in every project, so updates and new features are always tested before they go live. Our approach builds on wider expertise in software development and API integrations.
Frequently asked questions about building a WordPress website
A standard theme is a ready-made visual foundation that you can adjust through the WordPress dashboard. Custom WordPress development means we write a unique theme or child theme that fully reflects your brand identity and functional requirements, without the limitations of a generic theme. We also build bespoke plugins or adapt existing ones where the standard functionality falls short.
WordPress is a strong choice if you want to manage a content-rich site without a technical background, if you want to make use of a large ecosystem of plugins and integrations, or if you want to set up an online shop with WooCommerce. For highly complex applications or systems with demanding real-time requirements, a fully custom web application may be more suitable. We help you weigh up the right option.
With headless WordPress, WordPress serves only as the content management system in the background, while the front end is built with a modern JavaScript framework such as Next.js or Nuxt. Data is exchanged via the WordPress REST API or GraphQL. This typically delivers faster load times, greater flexibility on the front end and better options for Progressive Web App functionality. It is particularly worthwhile when performance and scalability are priorities.
Yes. We start with a technical audit of your existing installation: which plugins are in use, how the codebase is structured, and whether there are any security issues or outdated components. Based on that, we draw up a plan for takeover and further development. Sometimes we recommend a partial rebuild; sometimes a clean-up and optimisation is sufficient.
The scope of the project largely determines the cost: the number of pages, the complexity of the required functionality, whether bespoke plugins are needed, and whether it is a simple information site or a comprehensive WooCommerce shop with integrations to external systems. The degree of custom design and ongoing maintenance needs also play a role. In an introductory conversation, we quickly give you insight into the scope and the associated investment.
WordPress has a large attack surface by nature because of its popular plugin ecosystem. We reduce this by: installing only necessary plugins, applying updates regularly, setting up strong authentication, configuring a Web Application Firewall and automating backups. For custom code, we follow the WordPress Coding Standards and carry out a security review before handover.
Yes, we offer ongoing maintenance packages in which we keep WordPress core, themes and plugins up to date, regularly check backups and run security scans. This keeps your site stable and secure, even after the initial project has been handed over. You can also request one-off maintenance work if you prefer not to take on an ongoing package.
