Odoo Purchase is a fully-integrated app that helps companies manage their suppliers and purchase orders. It allows users to keep track of quotes, order statuses, quantity levels, and expected delivery dates. The app also has procurement tools that help businesses run efficiently with less stock and without any unforeseen stock-outs. Users can define stock levels, set up custom reordering rules, and import vendor pricelists/lead times. In the latest version, users can manage internal purchase requests, compute margins correctly, and request credit notes from suppliers.
