Invoice validation rules implemented by Iron Mountain are listed below. 

Purchase order (PO) number: Iron Mountain purchase order numbers on invoices are mandatory for suppliers designated as “PO Only”. Please reach out to your Iron Mountain business contact to validate your company’s designation.  In the United States and Canada, if the net invoice amount is under $1000 (USD and CAD), referencing a purchase order number is not required. 

Requestor name: To ensure accurate and timely invoice processing, referencing the Iron Mountain requestor’s name on your invoices is mandatory.

Invoice number for credit notes: Referencing the original invoice number on credit notes is mandatory for accurate and timely invoice processing.

Payment terms: Invoices will be paid according to the terms established on an active contractual agreement or the Iron Mountain terms and conditions referenced on the purchase order.  If no active agreement exists, the terms will be pre-defined to net 60.
