WooCommerce Development Agency
A WooCommerce development agency for stores that need more than plugins off the shelf
Custom functionality, complex integrations, and bespoke builds from a UK WooCommerce development agency with 13 years’ experience. When your store needs something that doesn’t exist yet, we build it.
You’ve hit the limits of what
Every WooCommerce store starts the same way. Install a plugin, configure it, move on. Before long you’ve got 40+ plugins, a site that takes eight seconds to load, and a checkout that breaks every time something updates. Or you need functionality that simply doesn’t exist as a plugin, and your current developer says “that’s not possible.” You need a WooCommerce development agecy that’s solved genuinely difficult WooCommerce problems before.
What We Build
Custom WooCommerce development for stores with complex requirements
Custom WooCommerce plugin development
Bespoke plugins built to your exact requirements rather than bending an off-the-shelf solution until it nearly works. Clean, maintainable code that’s built to WooCommerce standards and won’t break when the platform updates.
API integrations
Connecting WooCommerce to your ERP, CRM, warehouse management, accounting software, or any other system your business runs on. Two-way data sync, automated order flows, and real-time inventory management that eliminates manual work and human error.
Payment gateway integration
Standard gateways like Stripe and PayPal are straightforward. We handle the complex ones: specialist processors for regulated products, multi-currency setups, split payments, custom checkout flows, and gateways that require bespoke integration work.
Subscription and membership systems
Custom subscription logic, flexible billing cycles, pause and resume flows, tiered memberships, and subscriber portals. When the standard subscription plugins don’t cover your business model, we build what’s needed.
Checkout and cart customisation
Custom checkout fields, conditional logic, multi-step flows, upsell and cross-sell integration, and dynamic pricing. Everything aimed at reducing friction and increasing revenue per transaction.
Performance and architecture
Database optimisation, custom caching strategies, query optimisation, and architectural improvements for stores that have outgrown their original build. Making high-traffic, high-SKU stores fast and stable under load.
Migration and rebuild
Moving from another platform to WooCommerce, or rebuilding an existing WooCommerce store that’s accumulated years of technical debt. Full data migration, URL mapping, and a clean build that gives you a fresh foundation.
Third-party integrations and automation
Connecting WooCommerce to shipping providers, email platforms, marketing tools, loyalty programmes, and fulfilment services. Automating the manual processes that slow your operations down and introduce errors as order volumes grow.
How We Work
Development that’s scoped properly and delivered reliably
We scope before we quote.
Complex WooCommerce development can’t be estimated from a one-line brief. We take the time to understand what you need, how it fits into your existing setup, and what the edge cases are. You get a detailed scope and a fixed quote before any work begins.
We test before we deploy.
Everything is built and tested in a staging environment. You see it working, approve it, and then we deploy to live. No surprises, no “it worked on my machine” excuses.
We document what we build.
Custom development is only valuable if the next developer can understand it. We write clean, documented code and provide technical documentation so you’re never locked in or left guessing how something works.
We support what we build.
Custom functionality needs ongoing attention as WooCommerce, WordPress, and PHP evolve. We maintain compatibility, fix issues, and iterate on what we’ve built as your requirements change. Most development clients move into retainers for exactly this reason.
When to call a WooCommerce development agency
Signs your store needs custom development
You’re working around plugin limitations rather than solving the actual problem. Your site has 40+ plugins and you’re not sure what half of them do. Two systems that should talk to each other require manual data entry between them.
Your checkout doesn’t support the flow your business actually needs. You’ve been told “that’s not possible in WooCommerce” by someone who doesn’t know what they’re talking about. Your site performance has degraded to the point where plugin bloat is clearly the cause. You need functionality that’s specific to your business and doesn’t exist as a ready-made solution.
If any of that sounds familiar, you need a development team, not another plugin.

Frequently Asked Questions
What you need to know before we start working together.
WooCommerce Development
Done properly, the opposite. Custom development often replaces plugin bloat with lean, purpose-built code that does exactly what you need and nothing you don’t. Performance improvement is a common side effect of replacing multiple plugins with a single custom solution.
PHP, JavaScript, REST APIs, WooCommerce hooks and filters, WordPress custom post types and taxonomies, and modern front-end frameworks where appropriate. We build to WordPress and WooCommerce coding standards so everything is maintainable long term.
It depends entirely on complexity. Small integrations or customisations might be a few hundred pounds. Major custom builds, complex integrations, or architectural overhauls can run into thousands. We scope every project individually and give you a fixed quote before work begins. No hourly estimates that balloon.
Small to medium customisations typically take 1-3 weeks. Complex integrations and major feature builds take 4-8 weeks. Full store rebuilds take 6-10 weeks depending on scope. We’ll give you a realistic timeline during scoping.
We can. If you have an in-house developer or another agency handling other aspects of your site, we’re happy to collaborate. We’ll need access to staging, version control, and clear communication channels, but working alongside other teams is something we do regularly.
Yes. Most custom development clients move into a retainer that includes maintenance, support, and continued development capacity. The team that built your custom functionality is the same team that maintains and improves it over time.
Yes. We regularly take over projects that were built by someone else, including abandoned builds, half-finished features, and code that doesn’t work properly. We’ll audit what’s there, tell you honestly what’s worth keeping and what needs rebuilding, and give you a clear plan.
Yes. From initial design through to custom development, launch, and ongoing support. See our WooCommerce web design page for more on new store builds.
