WooCommerce development services built to scale

Custom themes and product architecture, checkout customisation, payments, subscriptions, B2B and wholesale, headless builds, migrations, and the database and query work that keeps a store fast as the catalogue grows.

WooCommerce gives you what Shopify does not: you own the code, the data, the checkout, and the roadmap. No platform fee on revenue, no app store gatekeeping, no functionality you cannot build. You also own the performance problem. Shopify rents you infrastructure that stays fast whether or not anyone is paying attention. WooCommerce hands you a database.

What we build

Fourteen kinds of work, including the database layer that most WooCommerce agencies leave alone.

{{ r.num }}

{{ r.a }}

{{ r.b }}

WooCommerce is WordPress, so themes, blocks, plugin architecture, and Git workflow are covered on our WordPress development page. This page is about the store: product data, checkout, and the query layer underneath both.

Where WooCommerce stores actually break

Not the theme. Almost never the theme. Six causes, all of them in the data layer. Tick the ones that sound like your store.

The pattern: WooCommerce performance is a data problem wearing a frontend problem's clothing. Optimising images on a store whose product query takes 1.8 seconds is treating the symptom.

Method

How we build

Six practices, most of them invisible in a design review and decisive in a load test.

{{ m.glyph }}

{{ m.title }}

{{ m.body }}

Search foundations are built in, not bolted on. Product and category schema, canonical handling across variations, faceted navigation that does not generate index bloat, and clean URL structure. We build these in because we run the ecommerce SEO audits that find them missing.

Interactive · the opinionated bit

WooCommerce or Shopify?

The question we get asked most, answered without platform loyalty. Three questions, and we will tell you plainly if the answer is the platform we are not selling.

What we would do

{{ fitTrade }}

A merchant who wants WooCommerce flexibility with no maintenance budget will be unhappy in eighteen months regardless of how well we build it. Saying so costs us a project and saves us both a rescue.

Choose WooCommerce when

Your business logic is unusual, your content and commerce are deeply intertwined, you need full data control, or platform fees at your revenue would exceed engineering costs.

Choose Shopify when

Your catalogue is conventional, your team is small, and you would rather spend on marketing than maintenance. Our Shopify development page covers that path.

The honest failure case

A business that chose WooCommerce for flexibility and then never invested in the engineering it requires. That store is slower and less reliable than the Shopify equivalent would have been, and the flexibility was never used.

Engineering

Scaling WooCommerce

Large WooCommerce stores work. They work because someone engineered them to, and here is what that involves.

Layer What matters
{{ r.a }} {{ r.b }}

The threshold where this stops being optional is usually somewhere around a few thousand products or meaningful concurrent traffic, whichever arrives first. Below that, a well-built store on good managed hosting is fine. Above it, engineering is the difference between a store that scales and one that falls over during a sale.

Both directions

Migrations

To WooCommerce

Commonly from Shopify or Magento. Products, variants, customers, order history, and content, mapped into a designed product architecture rather than imported into defaults. Complete URL mapping and redirects, since structure always changes. Integration reconnection. Baseline crawl before, monitoring after.

Away from WooCommerce

Which we also do. Some businesses are better served by a hosted platform, and pretending otherwise costs them more than admitting it does. Content and order history extraction, rebuild on the target platform, and a complete redirect map.

The recurring migration mistake

Importing products before designing the product architecture. Attributes become custom fields, variations become separate products, and the store carries that structure for years. We design the model first and import into it.

Get this scoped properly

An estimate, not a quote. Fixed price follows a scoping call, and where requirements are genuinely uncertain we run a paid discovery phase first.

Budget for maintenance. WooCommerce's lower platform cost is partly transferred into ongoing engineering, and stores that skip it are the ones we later rescue. A store without a maintenance arrangement is a store accumulating problems.

Our stack

Billion Game runs your work through the same instruments the best in-house teams use.

Licences are on us, and every export we pull from them is yours to keep.

{{ s.alt }}

Be wary of any agency whose reporting is a tool dashboard with their logo on it. Tools measure; they do not decide what matters, and every one of these will happily generate a hundred findings that change nothing. What you are paying for is the judgement about which three of those hundred are worth your developers’ time.
