Procurement software is a type of business software which helps to automate the organisational purchasing functions.

Software functions include issuing and evaluating tenders, raising and approving purchase orders, selecting and ordering the product or service, receiving and matching the invoice and order, and payment of invoices, enabling the procurement department to see everything that is ordered, ensure that nothing can be ordered without correct approvals, and secure the best value by combining several orders for the same type of good or even getting suppliers to bid for the business. A buying organisation's choice of software may be driven by the particular strengths offered by each individual system and the number of vendors available through them. A multinational or other large organization will use a shared procurement system to take advantage of economies of scale to drive down the cost of purchases. Whilst some services are available to purchase through automated systems, the key strength of these systems lies in the procurement of commodities that are much easier to standardize.
