If your school district/organization creates Purchase Orders for payment, the admin for the account can enter those PO numbers directly onto the invoice. There is no need to email, fax or send this PO’s directly to us.
Please understand that a PO is not payment, and the account will continue to show an open invoice until we have received the actual check. If you have a purchase order on file and you know the payment will not reach us by the due date, please email help@data-keeper.com and we will be happy to provide you with a grace period.
