WHAT YOU CAN EXPECT BY WORKING & PARTNERING WITH BOXCHILLI
A Trusted eCommerce Web Design Agency Since 2006
Your eCommerce business should be a sales machine, not a blocker to growth. At boxChilli, we bring together design, technology and strategy to create websites that perform across the entire funnel. From faster page loads and clearer product discovery to integrated marketing tools and scalable backends, we focus on eCommerce solutions that actually moves your business forward.
MADE FOR MODERN SHOPPERS, DESIGNED FOR MARKETERS
A successful online store needs to serve both ends of the equation: shoppers who want a fast, intuitive experience, and marketing teams who need control, speed and flexibility. That’s why our eCommerce builds are designed around real-world user journeys and business workflows. From intelligent search and product filtering to conversion-led checkout flows and campaign-ready landing pages, we deliver eCommerce development projects that are as easy to use as they are to manage – supporting everything from SEO and CRO to content, merchandising and paid media activity.
TECH THAT FITS THE WAY YOU WORK
Every business is different, and your website should reflect that. We build around your existing systems and workflows, creating integrations that streamline operations and remove friction across departments. Whether it’s stock syncs, API integration, multi-warehouse fulfilment or CRM automation, our eCommerce websites are engineered to fit your tech stack, your processes and your long-term goals, giving you a platform that feels tailored rather than restrictive.
PERFORMANCE-FIRST, FROM CODE TO CONVERSION
We approach every project with performance in mind, starting at the codebase and continuing through every layer of the site. Our website development build clean, lightweight foundations that meet Core Web Vitals, while our UX team designs journeys that prioritise clarity and speed. Structured data, semantic HTML and logical internal linking all come as standard, helping your store rank well, load quickly and deliver a consistently smooth experience across devices. The end result is a site that performs where it matters most… on the metrics that drive real sales.
NO MORE PAGE BUILDER BLOAT OR CMS HEADACHES
Managing your site shouldn’t feel like a chore. Our in-house WordPress SDK replaces bloated page builders and restrictive templates with a clean, flexible environment that keeps things fast, secure and easy to use. You’ll be able to update products, launch campaigns and edit content directly through WordPress, without wrestling with clunky interfaces or waiting on developers. It’s a content management system designed to empower your team, not slow them down.
INCLUSIVE EXPERIENCES, ACCESSIBLE FOR ALL USERS
An eCommerce site needs to work for everyone, including customers with disabilities. We build in line with WCAG best practices, supporting usability, clarity and legal compliance across your entire customer base. That includes semantic markup, alt texts, colour contrast and mobile device responsiveness – all designed to protect your brand and deliver a better experience to every user.
MIGRATING WITHOUT LOSING MOMENTUM
Replatforming doesn’t have to mean starting from scratch. Our migration process protects your visibility, rankings and user data while helping you unlock new performance opportunities. From redirect mapping and structured data preservation to analytics tracking and speed testing, we manage the full technical scope while ensuring continuity across SEO, content and organic traffic. Whether you’re moving from Magento to WooCommerce or upgrading a legacy WordPress site, we’ll make the transition seamless and search-safe.
EXPERIENCED, RELIABLE & HERE FOR THE LONG TERM
