A purchase requisition is a request for approval to purchase a material or service. An individual typically makes this request within a company that requires the material or service for their work. The requisition is then submitted to a manager or other decision-maker for approval.
If approved, the purchase requisition will be converted into a purchase order, which authorizes the company to buy the requested item from the supplier. If the requisition is not approved, the individual may need to seek alternate means of obtaining the material or service.
In ERP software, typically, a 3-step process should apply, which includes:
- Purchase Request
- Request for Proposal
- Purchase Order
Each of those processes should come with its approval processes.
