Unfortunately, on more than one occasion, the company or university issuing the purchase order did not pay for the rental by the payment due date. In multiple instances, several weeks and even months would go by before I could obtain the fee, and even then the late fees would not be paid.
Because of this disrespectful treatment by these companies and universities, I no longer accept purchase orders for rentals. All rentals must be paid in full prior to the score and PowerPoint being sent. If this is not acceptable to your organization or university, I recommend paying for the rental yourself and being reimbursed by your organization.
