Receiving Payment via the T-Pay Program

As of May 1, 2019, Tiedemann Advisors is transitioning to an electronic payment solution powered by Vendorin using Visa as our preferred method of payment of invoices.

Participation in Tiedemann Advisors’ T-Pay Program allows you to receive one-time-use Visa card payments on approved invoices from Tiedemann Advisors. YYou control the payment information you share with us, and remittance information is available at the click of a mouse. We’ve chosen Vendorin as our electronic payment partner because of their unmatched, 10-Point StopFraud ™ validation process that protects our vendors’ private payment information, and because of their stellar reputation in electronic payment processing.

To enable us to issue electronic payment for approved invoices, you will need to register on Vendorin’s T-Pay website at or over-the-phone with Vendorin’s T-Pay Registration Services Team at (888) 618-2550.
