# Selling Parts by Diagram: Exploded Parts Diagrams Online

> Exploded parts diagrams become a shoppable ordering surface when callouts are live: the buyer clicks the part on the diagram, sees price and availability, and builds a multi-part cart from one view. Diagram ordering also prevents the wrong-part returns that come from guessing at part numbers in a list.

## Frequently asked questions

### What is diagram-based parts ordering?

An exploded-view drawing where every callout is a live, clickable link to the actual SKU: the buyer finds the part visually in its assembly, selects it, and orders from the diagram, with price, stock, and account pricing attached at the moment of selection.

### Do shoppable diagrams reduce wrong-part returns?

Yes, by removing visual misidentification, the largest source of parts-order guesswork. A buyer who confirmed the part in its position on the assembly has verified it the way a counter person would, before purchase rather than after delivery.

### Where do exploded parts diagrams come from?

From OEM parts books and manufacturers' own technical documentation. Making them shoppable is a mapping project: every callout linked to a current SKU, maintained through part supersessions, and versioned across model years and serial ranges.

### How does diagram ordering work with Year-Make-Model fitment?

Fitment selection comes first: the buyer's vehicle or machine narrows the catalog, and the diagrams shown are the ones that apply to it. The two layers answer different questions, which machine, then which part on it, and work best in sequence.
