If you need to make a payment through ECSI, you will first need to create an ECSI account. Log in to ECSI On the main menu page, you will find ¨Make a Payment¨. At the bottom of this section (which is in the upper left hand column of the screen). You will see ¨International Payment¨. After clicking on this you will be redirected to Flywire payment process! We then deliver your payment to ECSI and ECSI sends out the payment to your educational institution.
