Paying Your Bill
The Office of the Bursar offers several payment options: the monthly Cornell Installment Plan, electronic payments via Net.Pay, and wire transfers. We accept check payments by mail, and check or cash payments in person. Other payment options include third-party billing (for sponsored students) and college savings plans.
I have found the electronic payment via Net.Pay the best option for me. There is a one-time setup with bank information (account number, routing number). I wait until the funds are due (I am billed electronically) and then I make the transfer myself. Very simple!
