WORDPRESS, ECOMMERCE AND BESPOKE WEB DESIGN
specialist Sussex website design & development services
Website design and development spans a broad range of requirements, with effective mobile performance, strong search visibility, and high-quality digital design shaped by how a business operates, sells, and manages content on a daily basis.
From Chichester and Crawley through to the lanes of Brighton, we work with organisations ranging from service-led businesses and professional firms to retailers and multi-location operators. Each requires a different type of platform, whether that is a flexible WordPress website to support ongoing marketing activity, a robust WooCommerce setup to manage products and transactions, or bespoke functionality delivered through a carefully planned website migration from an existing system.
To reflect this range, our website design and development services are structured into dedicated areas, each focused on a specific type of build or technical requirement. This approach allows Sussex businesses to explore the services most relevant to their needs in detail, with clear insight into how different website types are planned, built, and supported by our in-house development team based in neighbouring Hampshire, offering high-level expertise without the overheads and pricing often associated with Brighton agencies.
WordPress Websites
With extensive WordPress knowledge in-house, we design and develop fully responsive WordPress websites that support how Sussex businesses manage marketing, content, and daily operations. Each site is built using our proprietary SDK rather than off-the-shelf themes or page builders, ensuring the structure reflects how the business actually works, with tailored layouts, intuitive content management, and capacity to adapt as requirements change.
This approach provides full control without unnecessary complexity, making it straightforward to update content, add new pages, or introduce integrations as the business grows. With a considered CMS structure and a codebase designed for long-term maintainability, your WordPress website remains easy to manage internally while offering a reliable foundation for future development.
WooCommerce Websites
As an alternative to platforms like Shopify and Magento, WooCommerce offers greater flexibility for businesses that want more control over how their online store operates and scales. Built on WordPress using our proprietary SDK, each WooCommerce website is designed to support practical trading needs, from advanced product structures and promotional logic through to payment processing, fulfilment, and reporting, without locking you into fixed templates or escalating platform costs.
A clean, modular build ensures stores remain simple to manage while accommodating integrations with payment providers, shipping tools, and wider third-party systems. This allows Sussex businesses to adjust product ranges, customer journeys, and operational workflows over time, without needing to replace or rebuild the core platform as the business evolves.
eCommerce Websites
The requirements of selling online vary significantly based on product types, customer behaviour, and internal processes. Our eCommerce websites are designed for organisations that require considered user journeys, logical product structures, and platforms that reflect how they operate day to day, whether delivered through WooCommerce, platforms such as Shopify or Magento, or as part of a managed migration from more complex systems including Drupal.
By prioritising structure and usability, eCommerce platforms remain easy to manage while continuing to adapt as business needs evolve. From product catalogues and checkout journeys to third-party integrations, every build is shaped to support day-to-day trading, ensuring intuitive customer journeys and a platform that remains straightforward to extend over time.
Bespoke Websites
Many businesses across Sussex have requirements that fall outside the capabilities of conventional CMS or eCommerce platforms, particularly when processes, data, or user interactions are highly individual. Bespoke website development provides a more flexible approach, enabling custom-built functionality, tailored workflows, and specialist integrations beyond standard, pre-packaged solutions.
Using our SDK as a stable foundation where appropriate, bespoke builds are designed with long-term maintainability in mind, allowing complex requirements to be delivered without sacrificing fast loading speeds or control. This approach makes it easier to extend functionality for your new site over time as operational needs change.
Website Migrations
The decision to migrate a website is typically driven by limitations within existing platforms, aging systems, or management complexity. Every migration is approached methodically to safeguard content structure, web presence, and SEO performance, while delivering a platform that is easier to manage and extend over time.
Existing platforms are reviewed in detail before any rebuild or transition takes place, ensuring critical functionality, data, and content are retained throughout the process. Whether consolidating multiple websites or migrating to WordPress or WooCommerce, each migration is handled methodically to deliver a cleaner, more dependable platform that supports future development.
FREQUENTLY ASKED QUESTIONS
Cant find the answer you are looking for?Get in touch and we will be happy to help
Q. How long does it take to build a website?
Most website design and development projects are delivered within around 16 weeks, although timelines can vary based on the scope and complexity of the build, as well as the speed of feedback and content provision. From the outset, clear milestones are agreed and progress is communicated throughout, so you always have visibility of the current stage and upcoming steps.
Q. What is the process for feedback, revisions and approvals?
Every stage of the process includes defined feedback and approval checkpoints to maintain control as the project progresses. Designs are reviewed and refined through structured discussion, with development gated by formal sign-off, ensuring changes are made collaboratively and at the right stage instead of being rushed or introduced later.
Q. What ongoing support or maintenance services do you offer after launch?
Following launch, we’re available to continue to support your website as it becomes embedded in everyday use. This includes post-launch aftercare to identify and resolve issues, together with optional ongoing support and maintenance services that maintain security, stability, and long-term reliability as the site evolves alongside the business.
Q. How much do your websites cost?
The cost of a website is shaped by its scope, functionality, and overall complexity, with very different requirements between simple brochure sites and advanced eCommerce platforms. Elements including template volume, system integrations, content requirements, and technical constraints all contribute to the level of work required. Instead of fixed packages, we produce transparent, bespoke proposals that clearly define inclusions and demonstrate how the investment aligns with broader business goals.
Q. What software and tools do you use?
Industry-leading tools underpin our design and development process to support clear communication, effective collaboration, and efficient delivery. Designs are produced in Figma, enabling layouts and interactions to be reviewed and refined in detail prior to development. Final builds are delivered using our proprietary SDK and a technical stack selected to suit the performance, scalability, and long-term needs of each project.
Q. What’s the difference between a custom WordPress site and a headless website?
A custom WordPress site uses the traditional CMS with everything closely connected – ideal for East & West Sussex businesses that need control and easy editing for their marketing team. A headless website separates the backend from the frontend, giving you lightning-fast performance, modern technologies like React or Next.js, and flexible integrations with third-party tools.
Q. Will my new website be optimised for SEO?
Yes, our web developers build every site with SEO in mind from day one. That means fast loading times, mobile-first design, clean semantic code, schema markup and optimised metadata. If you’re moving from another platform, we’ll manage redirects and preserve rankings so your Sussex business doesn’t lose visibility.
Q. Do I need to rebuild from scratch or can you improve my existing website?
It depends on your goals and how your current site was built. If your site has a strong foundation, we can often make performance, design and usability improvements without starting from scratch. But if it’s holding back your growth, whether due to bloated code, poor structure or limited flexibility, investing in a brand new website may be more cost-effective in the long run.
Q. Will my website be mobile-friendly?
Absolutely. Making sure your new site is optimal for mobile users is standard in our process, and every website is tested across different mobile phones, devices and browsers. This matters in counties like East and West Sussex, where mobile-first browsing is common across sectors from retail to hospitality.
Q. What is a CMS and which one should I use?
A CMS (Content Management System) is what allows you to manage your website content without needing a developer. We typically recommend WordPress for its flexibility, SEO-friendliness and ease of use, but we also build with modern frameworks for clients who need more advanced content workflows, platforms that are highly functional or eCommerce capabilities like an online store.
Q. What’s your approach to web design and development?
We take a strategic, user-first approach. Our process starts with discovery and planning, where we explore your goals, customers and target audience. From there we develop wireframes and design concepts that align with your branding services and business needs. We then build clean, high-performing websites that support long-term growth.
Q. How do you keep websites performing after launch?
We don’t walk away once a site goes live. Our aftercare includes technical maintenance, SEO checks, CRO improvements and ongoing support. Many Sussex clients love continuing to work with us long-term because they see consistent improvements rather than one-off fixes.
Q. What makes boxChilli different from other web agencies?
We’ve been building websites since 2006 and have grown up alongside Sussex’s business community. All work is done by our in-house team of designers, developers and SEO specialists – no outsourcing, no shortcuts. That mix of local insight and technical expertise means we can create websites that are both high-performing and relevant to your audience, whilst ensuring search engines can find it and driving measurable growth.
Q. We have a limited budget, will you still work with us?
We’re happy to scope projects of different sizes and suggest phased approaches where possible. If a full custom build isn’t viable right now, we can offer scaled-down solutions or roadmap support to help you move forward strategically.
Q. What are your values and how do they shape the work you do?
At boxChilli, our core values (integrity, creativity and client focus) are built into everything we do. We’re honest about what will work, proactive in solving problems and always shape our recommendations around your business goals and data. Our work goes beyond the website – it’s part of your broader digital strategy and supports the digital services that keep your business moving.
