One fitment dataset. Every channel.
Most parts sellers keep fitment in four places that disagree with each other: the website, the eBay store, a supplier spreadsheet and someone's head. We fix the source, then feed everything from it.
Why fitment data is the whole business
Fitment is the product. A coilover kit isn't a coilover kit; it's "a coilover kit for a 2013–2017 Fiesta ST with the 1.6 EcoBoost". If that relationship is wrong, incomplete or stored as free text, everything downstream breaks: the reg lookup gives false negatives, eBay shows your part to the wrong cars, Google can't tell what vehicles the page is about, and the customer buys the wrong thing.
Getting it right isn't glamorous. It's spreadsheets, vehicle catalogues and a lot of de-duplication. But it's the single highest-return job in a parts business, and almost nobody does it properly.
What we do with your data
- Gather — supplier spreadsheets, TecDoc exports, ACES/PIES-style files, your existing website and eBay exports, that CSV someone built in 2014.
- Normalise — one structure for everything: make, model, body, years, engine code, fuel, drive, plus fitment notes and positions (front/rear, left/right).
- Map to K-Type — every fitment row keyed to the TecDoc vehicle ID the UK aftermarket runs on, which is also what reg-lookup APIs return.
- Map to ePID — a maintained K-Type → eBay ePID mapping so your website and your eBay compatibility lists finally say the same thing.
- De-duplicate and sanity-check — find the 400 variants of "Ford Fiesta MK7", the years that overlap wrongly, the parts that claim to fit a diesel and a petrol at the same time.
- Handle supersessions & cross-refs — old part numbers resolve to current ones, competitor and OE numbers resolve to yours.
- Syndicate — the master dataset feeds your website, eBay, Amazon Automotive and Google Shopping. Edit once, update everywhere.
- Keep it alive — new vehicles, new parts, supplier updates: a process, not a one-off.
Signs your fitment data is costing you money
- "Doesn't fit" returns that turn out to be data errors, not customer errors
- eBay compatibility lists that were bulk-pasted years ago and never checked
- The same vehicle spelled six different ways across your catalogue
- Adding a new product means updating fitment in three systems by hand
- Nobody's sure which parts fit the facelift model
What you get
A clean master fitment dataset mapped to K-Type and ePID; a written report of what was wrong and what we changed; import files or live feeds for each channel; and, if you want it, an ongoing arrangement where we maintain it as your catalogue grows.
