Online shops built around "will it fit?"
Ecommerce for performance and aftermarket parts: registration lookup, year/make/model search, part-number and cross-reference search, supersessions and trade pricing. On WooCommerce, Shopify, Magento or a bespoke build — whichever your catalogue actually needs.
Parts aren't t-shirts
Most ecommerce platforms and most agencies assume a customer knows what they want, searches for it by name, and buys it. Parts buyers don't shop like that. They have a car and a problem. They want to type in a reg, see what fits, and trust the answer — because a wrong part means a return, a re-order, a weekend wasted and a one-star review.
Everything we build starts from that. The vehicle is the primary way into the catalogue, not a filter bolted on afterwards.
What we build
- Registration lookup — plate in, exact vehicle out (make, model, year range, engine, K-Type), then the whole catalogue filtered to what fits. Remembered across the session, so they don't have to keep entering it.
- Year / make / model / engine search — for customers without a plate handy, imports, or trade buyers browsing for a customer's car.
- Part-number search that forgives — OE numbers, your SKUs, supplier numbers, cross-references and superseded numbers all resolve to the right product. Spaces, dashes and case ignored.
- Fitment on the product page — a proper compatibility table, fitment notes ("not for cars with factory sport suspension"), and a clear yes/no against the customer's vehicle.
- Category and brand structure that mirrors how the trade thinks: by vehicle, by system (brakes, suspension, exhaust), by brand — with landing pages Google can rank.
- Trade accounts & pricing — tiered pricing, account applications, credit terms, quick-order by part number, bulk upload from a spreadsheet.
- Integrations — eBay, Amazon, Google Shopping, your accounts package, courier labels, stock from your supplier feeds.
Platform, honestlyWooCommerce is right for most UK parts retailers up to a few tens of thousands of SKUs. Shopify is quick to launch but fitment needs custom work. Magento or bespoke earns its keep above that, or for serious B2B. We've built on all of them and we'll tell you which fits your data, not which one we fancy building.
Signs you need this
- Customers email or ring to ask "will this fit my car?" before ordering
- Your returns rate on "wrong part" is above a couple of percent
- Fitment lives in product descriptions as free text
- You've got a great eBay store and a website that embarrasses you
- Trade customers still order by phone or email because the site can't do their pricing
How a build goes
- Data first. We export what you've got, clean it and get the fitment data right before touching design. This is where projects go wrong if you skip it.
- Design around the vehicle. Reg lookup in the header. Fitment on every product. Category pages that make sense to someone who's just typed in "Mk7 Fiesta".
- Build, integrate, migrate. Platform build, marketplace and accounts integrations, redirects from every old URL so rankings carry over.
- Launch and measure. Search console, analytics that track vehicle searches and fitment checks, and a monthly report you can read in five minutes.
Questions
Parts ecommerce FAQ
Which platform is best for selling car parts online?
It depends on catalogue size and how you sell. WooCommerce suits most UK parts retailers up to a few tens of thousands of SKUs and integrates well with fitment plugins and eBay. Shopify is fast to launch but fitment needs apps or custom work. Magento and bespoke builds make sense for very large catalogues, B2B trade pricing or complex integrations. We'll recommend based on your data, not our preferences.
Can you add a registration lookup to my existing website?
Usually, yes. Reg lookup uses a UK vehicle data API to resolve a plate to make, model, year, engine and K-Type, which then filters your catalogue. The hard part is not the lookup itself but having clean fitment data behind it — which is where we usually start.
Do you migrate existing product and fitment data?
Yes. Migration is most of the job on a parts site. We export, clean, de-duplicate and re-map fitment before it goes anywhere near the new platform, and we keep old URLs redirecting so you don't lose rankings.
How long does a parts website take?
A WooCommerce or Shopify build with clean data: typically 8–12 weeks. Add time if the fitment data needs serious work or there are several integrations. We'll give you a real timeline after the audit, not a guess on a call.
