Payment Methods

Tesoro’s preferred method of payment is Electronic Funds Transfer (EFT).

What is EFT?

An Electronic Funds Transfer (EFT) Payment is a form of electronic funds transfer that provides a secure, efficient method of receiving payment through the Automated Clearing House (ACH) Network. The ACH Network is a batch-oriented processing and delivery system that provides for the distribution and settlement of electronic transactions and payments among financial institutions.
