Understanding Marsh policy
Vendor activation or modifications requires collaboration between the Marsh Business Owner, Global Vendor Maintenance Team, and Vendor.
Marsh Global Policy mandates
- Verification of Vendor information is viewed and managed by the Marsh Vendor Maintenance Team only.
- Marsh Business requestor is not allowed to submit or forward information on behalf of the Vendor. If the Vendor does not provide the information through our Vendor management portal directly to the Vendor management team, the Vendor record will not be activated in our ERP system.
- NO PO, NO PAY - Vendor must obtain a valid Purchase Order number (PO#) from Marsh before delivering any goods and services. It is crucial that Purchase Order Number is clearly indicated on each invoice. Invoices lacking a PO number or issued prior to the sending of the purchase order will be rejected and further delay in payment.
- Invoices must be submitted directly by the Vendor per the Billing Instructions on the Purchase Order.
Vendor's Responsibilities
- Vendor manages their record (Modification) on the Marsh Vendor management portal (Apexanalytix)
- Vendor to respond requested information in a timely manner through the Marsh Vendor Management portal.
- Submit all documents in a PDF format or other formats requested.
- If the Vendor does not provide the required information after 3 requests, the Marsh Vendor Maintenance team will close the ticket, and Vendor will not be activated in Marsh purchasing & payment system.
Vendor Activation Process
Once the Marsh Vendor Maintenance Team receives all the required information from the Vendor the expected turnaround time for activation is within 6 business days.

"Vendor" and "supplier" are interchangeable terms for providers of goods or services.
Payment related information
- Marsh Standard Payment Terms: In the absence of a signed contract between Marsh and the Vendor, Marsh Standard Payment terms are 45 days from the receipt date. Payment Terms are noted on the Purchase Order Document issued to the Vendor.
- Marsh's preferred method of payment is EFT (Electronic Funds Transfer). Other forms of payment increase risk.
- Vendors can contact the Marsh Accounts Payable team to inquire about invoice payment status. The email address to contact is also located on Marsh's Vendor page of our Marsh public website.

You are required to have a Purchase Order (PO) in your possession before providing any goods or services to any Marsh 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:
- North America: AME.internal.invoices@mmc.com
- Europe, Middle East & Africa: EMEA.Internal.Invoices@mmc.com
- Asia Pacific: APAC.Internal.Invoices@mmc.com
- Latin America: MMC.LATAM.AP.Invoices@mmc.com
