Part 4 Purchase Management

Purchase management is the process that turns internal demand into vendor orders, receipts, vendor bills, and cost records. In Odoo, Purchase is closely connected with products, vendors, inventory, accounting, replenishment, and manufacturing.

This part starts from the standard RFQ and purchase order flow, then explains how purchase confirmation creates receipts, how expected delivery dates and vendor lead times affect planning, how basic purchase approval works, and how purchase receipt affects product cost. The goal is to help readers understand procurement not as a standalone order screen, but as the upstream half of inventory and cost control.
