Purchasing & Payments
Marsh McLennan Suppliers, please watch this short three-minute video for important tips on how to transact with Marsh McLennan in the most efficient manner to ensure on-time payment. Thank you!
Invoicing Marsh McLennan
You are required to have a Purchase Order (PO) in your possession before providing any goods or services to any Marsh McLennan business. Once you have the PO, you have authority to supply, and you must invoice us as follows. Failure to follow this process will significantly delay your payment:
- Email your invoices in pdf format (black & white/mono only) without delay, making sure that the purchase order (PO) number is included and send them to the appropriate regional mailbox:
- Remember to send one pdf invoice per email. Multiple invoices per email complicate processing and will result in lost invoices.
- Where available, please use the Tungsten portal to upload invoices. https://www.tungsten-network.com/customer-campaigns/marshmclennan/
