Add or Update a Purchase Order Number

How to add or amend existing Purchase Order numbers across billing accounts.
Please be aware that it is a client's responsibility to provide a purchase order number prior to an invoice generating. If a Pitney Bowes invoice remains unpaid due to an incorrect purchase order number, this may result in fees or a hold being applied to your account. 

Purchase and Supply Invoices
