Marsh & McLennan Companies, Inc. (MMC) requires all suppliers to include a valid MMC purchase order (PO) number on every invoice.  Supplier invoice should match the PO line items to support reconciliation and payment. Invoices received without a valid MMC supplied purchase order number will be rejected and returned to the supplier without payment.

First-time Suppliers must complete a one-time setup process, initiated by the MMC business contact.  Communication during setup will be between the MMC Global Supplier Maintenance team and Supplier. Per company policy, the MMC business contacts cannot act as an intermediary in requested setup information. Setup may require information such as: W8/W9, banking details, sample invoice, remittance and PO delivery addresses. Upon receipt of all required information, supplier setup requires a minimum of 4 business days to complete so that MMC may conduct proper supplier validation.
