=============================================
From purchase order to invoice and receptions
=============================================

For most of your everyday purchases, chances are you already know where
to purchase and at what price. For these cases, a simple Purchase Order
(PO) will allow you to handle the whole process.

In Odoo, a purchase order can be created as is, but can also be the
result of a Request for Quotation or of a Purchase Tender. Therefore,
every purchase made in Odoo has a PO.

The PO will generate an invoice, and depending on the contract with your
supplier, you will be required to pay the invoice before or after
delivery.

Install the Purchase Management application
