Your eBill is due upon receipt. To avoid a late fee, payments must be posted by 6:00 p.m. (EST) on a payment due date. Online payment (Credit Card or eCheck) is the University at Buffalo’s preferred payment method. When paying online, payments are posted to the student account in real-time. For release of an unpaid bill hold, please allow 24-48 hours after payment has been posted to your account.
