A purchase order online is an electronic request to buy goods and services. It is created when a supplier receives an order from a customer and communicates the details of the order to the buyer by way of an online platform. Purchase orders online can be used in both business-to-business (B2B) and business-to-consumer (B2C) transactions and are typically authenticated, stored and tracked electronically. The benefits of using purchase orders online include enhanced accuracy, greater transparency, reduced paperwork and improved document control. Implementing purchase orders online also helps optimize processes, reduce costs and increase efficiency.
