Washington University’s default method of paying suppliers and miscellaneous payees is via check. Alternate forms of electronic payments are available for both domestic and international payees.
The university’s preferred method of payment for domestic payees is an electronic payment directly to the supplier’s bank account via an ACH/EFT transaction. See ACH Payments for instructions to enable ACH payments.
Payments via wire transfer is a good option for international payments. In general, wire transfers are used when a foreign country doesn’t accept US checks or when currency conversion is required. See Wire Transfers for further details.
