Purchase Order Plus is a Xero add on that improves the functionality of Purchase Oder's (PO). Using Purchase Order Plus (POP), users will have the ability to create and approve purchase orders on any mobile device. POP integrates direct with your Xero file which gives you the ability to quickly enter information into a purchase order. Control your purchasing function using a custom approval workflow, based on total spend, tracking codes, and/or suppliers. Do you want your employees to create purchase orders, but don’t want to give them access to your entire Xero accounting system? POP can do this.
