# Selling Tractor & Implement Parts Online with Fitment

> Tractor and implement parts sell online through make/model fitment built from OEM parts book data, with serial-range accuracy deciding whether the part fits the machine in the field, and diagram-based ordering that lets farmers buy from exploded views. This guide covers the data work and the storefront experience.

## Frequently asked questions

### Is there an ACES/PIES equivalent for tractor and implement parts?

No. ACES and PIES are automotive standards. Agricultural fitment data lives in OEM parts books organized by make, model, and serial-number range, which means an ag parts seller assembles and owns their fitment data layer rather than licensing a finished one.

### Why do serial numbers matter for tractor parts fitment?

Because manufacturers change components mid-production. Parts books specify applications like "serial number 123456 and up," so two machines of the same model can take different parts. A fitment layer that stops at make and model will be confidently wrong for exactly those cases.

### What is diagram-based parts ordering?

The buyer navigates an exploded parts diagram of the machine or assembly, clicks the callout for the part they need, and orders from the pin, no part number or search terms required. It mirrors how OEM dealer portals work and how mechanical knowledge is actually organized.

### Can one store serve both farmers and dealer accounts?

Yes, and it should. The fitment-filtered catalog is shared, while B2B company accounts layer dealer pricing, net terms, and reorder workflows on top. Running two separate stores means maintaining the hardest asset, the fitment data, twice.
