WooCommerce development agency.
Want to talk about how Fifteen can help you?
We’re a UK team of WooCommerce developers who build, fix, and grow online shops on WordPress. If you want full control of your store, on a platform that’s free to use and has room for whatever your business needs, WooCommerce is usually the right choice, and we’ll build it properly.
WooCommerce website development services.
Whether you need a new shop or help with the one you’ve already got, we cover the whole job, from design and build through to integrations and support. Here’s what that includes:
- New WooCommerce websites, usually on a custom WordPress theme, designed around how your customers buy.
- Custom functionality: trade and B2B pricing, subscriptions, product builders, member areas, and reward schemes.
- Integrations with EPOS, ERP, CRM, accounts, stock feeds, and payment gateways.
- Rescue work on slow or unstable WooCommerce sites: plugin clean-ups, database tuning, hosting, and caching.
- Migrations to WooCommerce from other platforms, with every old URL redirected.
- Support after launch: hosting, security and support together under a service level agreement (SLA), or development support for updates, fixes, and new features if your shop is hosted elsewhere.
When WooCommerce is the right choice.
WooCommerce suits businesses that want content and commerce on one WordPress site, need custom features, or don’t want a monthly platform subscription. The trade-off is that you’re responsible for hosting, updates, and security. That’s fine with the right support in place, and a risk without it. We’re a WooCommerce development agency, but we build on Shopify and Shopware too, so if one of those would suit you better, we’ll tell you.
How our WooCommerce developers work.
Every shop starts with how your customers buy, not with a theme. From there, a typical project runs like this:
- Discovery: your products, customers, margins, and the systems the shop needs to connect to.
- UX: product, basket, and checkout journeys mapped and wireframed.
- Build: usually a custom theme, only the plugins you need, and custom code where a plugin would slow things down.
- Testing: test orders end to end, payment gateways, emails, devices, and speed.
- Launch: redirects, GA4 ecommerce tracking, and Search Console checks.
- Aftercare (optional): hosting with 24/7 monitoring and support under an SLA, or development support if you host elsewhere. Either way, the same developers each time you call.
If you want to grow sales after launch, our SEO, paid search, email, and conversion teams work on the same shop.

Frequently asked questions.
How long does a WooCommerce build take?
A typical WooCommerce shop can go from first conversation to launch in two to four weeks, including design, planning, the build, and testing. Integrations with stock or accounts systems, product data migration, and how quickly feedback comes back are what usually add time.
How much does a WooCommerce website cost?
WooCommerce itself is free, so you pay for the build and the running costs. The build depends on the size of your catalogue, custom features, such as trade pricing or subscriptions, and integrations with stock, EPOS or accounts systems. Running costs are hosting, any premium plugins and extensions, transaction fees (these depend on the payment provider you choose) and if you want one, a support package. You’ll get a clear quote after a short scoping call.
Why hire WooCommerce website developers instead of building it ourselves?
You can get a basic WooCommerce shop running yourself. Where it gets hard is speed with a large catalogue, payment, and stock integrations, security, and keeping dozens of plugins updated without breaking checkout. That’s usually when people come to us.
Can you fix our slow WooCommerce site?
Usually, yes. Slow WooCommerce sites tend to have too many plugins, a heavy theme, an unoptimised database, or underpowered hosting. We audit all four, tell you what’s causing it, and fix the biggest problems first.
Can you take over support of our existing WooCommerce shop?
Yes. We start with a health check of the theme, plugins, hosting, and security, then take over updates and fixes. If we host the shop too, hosting, security, and support are covered by an SLA. Either way, you deal with the same developers.
WooCommerce or Shopify: Which should we choose?
WooCommerce is free to use, gives you more control, and keeps your content and shop on one WordPress site. You pay your payment provider’s transaction fees and for any premium plugins. Shopify is simpler to run because hosting and security are handled for you. We build both and will recommend whichever suits your business.
Can WooCommerce handle B2B and trade pricing?
Yes, with the right setup: customer-specific price lists, trade accounts, minimum order quantities, quote requests, and invoice payments. We build these with established extensions or custom code, depending on how complex your pricing is.
