# Procurement process
In this article we will look at how the procurement process works. It all starts with the creation of a purchase invoice, which should be approved before it is issued, continues with the approval process and finally with its confirmation of payment.
The following users are involved in the process:
- owner who created the purchase invoice.
- chief approvers who are in charge of approving the purchase invoice.
- category level approvers who approve an invoice based on whether the purchased product falls under their category.
- accountant who confirms that a payment has been sent.
