# Facilities, Inventory & Vendors Overview
> Overview of the Facilities, Inventory & Vendors core in Encore OS — purpose, scope, and key responsibilities.
The Facilities, Inventory & Vendors core (FM) manages physical operations for Encore OS — facilities maintenance, inventory tracking, vendor management, purchase management, fleet, and facilities administration.
**Architecture:** FM is a domain core that depends only on **Platform Foundation**. Purchase-to-pay flows hand off to **Finance & Revenue** for accounts payable.
## Purchase-to-pay & operations
Inventory reorder points and maintenance work orders raise requisitions against onboarded vendors. A purchase order is issued, goods are received, and a three-way match clears the bill into Finance accounts payable.
