For businesses looking to grow their product lines with growing customers, POs simplify this process. There’s no one else to take care of the pending orders, eliminate duplicate orders, or rectify order errors. Purchase orders are the basis for process management, especially in manufacturing. Training people in the purchasing department to put in a purchase request, creating automation processes to generate POs based on stocks that dip below a threshold, and recruiting finance staff to approve POs will help ease things up long term.
