Most Online Stores Leak Sales. Yours Won’t.

Traffic is expensive — wasting it is worse. We design and build every store around the things that actually turn browsers into buyers, then keep measuring and improving them long after launch.

The typical store

Leaks sales at every step

Pages that crawl on mobile, so shoppers bounce before they even see your products
A clunky, multi-step checkout that loses people at the very last hurdle
A layout that works on desktop but fights customers on a phone
No reviews, trust badges or reassurance at the moment someone decides to buy
Products buried where shoppers can’t search, filter or find them
Built by Square Internet

Turns browsers into buyers

Fast Core Web Vitals so pages feel instant — and rank better in Google
A streamlined, one-page checkout engineered to remove friction
A mobile-first build, because that’s where most of your traffic and sales are
Reviews, trust signals and clear delivery info right where they count
Smart search, filtering and merchandising that guide people to “add to basket”

WooCommerce Development Agency Process

No jargon, no disappearing project managers. You work directly with the UK team designing and building your store, with a clear plan at every step.

Discovery & Scope
We start by understanding your products, customers and goals, then map out the store — features, integrations and budget — so the plan is clear before a line of code is written.
02
Design & Build
Our WooCommerce developer agency designs your store around conversion, then builds it with clean, scalable code, your integrations wired in, and everything fully tested on staging before going live.
03
Launch & Grow
We launch carefully with no downtime, then stay on hand with 30 days of free support — and optional ongoing care to keep optimising and growing your store.

Our customers rate us EXCELLENT.

WooCommerce Development Questions, Answered

WooCommerce is the world’s most popular ecommerce platform — an open-source plugin that turns WordPress into a full online store. It’s flexible, cost-effective and scales from a handful of products to enterprise B2B catalogues, with no ongoing licence fees. For most businesses that want full control of their store and content, it’s an excellent fit.

It depends on the size and complexity — the number of products, the integrations you need, and how bespoke the design and functionality are. We scope every project up front and give you a clear, fixed quote before any work starts, so there are no surprises. Tell us what you’re after and we’ll give you an honest estimate.

A straightforward store can be live in a few weeks; larger, heavily integrated or B2B builds take longer. After our discovery session we’ll give you a realistic timeline with clear milestones, and we keep you updated at every stage rather than going quiet for weeks.

Yes. We move stores to WooCommerce from Shopify, Magento, Wix and other platforms regularly — products, customers, orders, content and SEO all carried across with no lost data, broken URLs or downtime. We handle the technical detail and pre- and post-launch checks so the switch is smooth.

Absolutely. When an off-the-shelf plugin doesn’t do quite what you need, we build custom extensions to spec. We also integrate WooCommerce with ERPs, CRMs, payment gateways, shipping, accounting and any other system you run — so your store and your back office stay in sync.

Yes — WooCommerce powers some seriously large stores. We build high-volume, multi-currency and B2B/wholesale stores with trade pricing, bulk ordering and deep integrations, with performance and security engineered in from the start. See more on enterprise builds above.

Performance and SEO are built in, not bolted on. We optimise Core Web Vitals, use clean and efficient code, and follow technical SEO best practice so your store loads fast, ranks well and converts more of the traffic it earns.

Yes. Every build includes 30 days of free support after launch, and you can carry on with an ongoing care plan covering updates, security, backups and monitoring — so your store keeps running and selling without you having to think about it.
