Box Autopart, the salvage yard in one app.
A Windows desktop system for auto salvage businesses. It tracks every vehicle and part, records sales across platforms, works out real profit after fees and shipping, and syncs orders straight from eBay.
Built for the people who sell car parts.
Salvage businesses buy whole vehicles, strip them into parts and sell those parts on eBay and locally. Spreadsheets lose track of which part came from which car and what it really earned once fees and shipping are taken off.
Box Autopart links every part to its vehicle, records every sale with its eBay and PayPal fees, shipping and carrier adjustments, and shows the true net profit and margin. Orders flow in automatically through the eBay REST API with OAuth 2.0.
