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.
