Suppliers must submit an invoice in order to receive a payment for all non-purchase order, third-party, American Express or P-Card purchases. Invoices for purchases not on a purchase order must be fully approved by authorized Iron Mountain personnel prior to issuing payment. For faster payment, all supplier invoices must clearly bear the Iron Mountain PO number, taxes (if applicable), legible and typed text, and be arithmetically correct. Only PDF format is allowed for digital invoices.

Please send invoicing receipts to the Iron Mountain Accounts Payable department. Incorrect invoices will not be processed and can significantly delay payment.
