If I have authorized a payment to Ritter through my bank online (not Ritter’s online bill pay site), why does it not post to my account the day I authorized it to be paid?

Even though it may show money drafted from a customer’s account by the bank on the date authorized, Ritter does not receive those funds in real time. The bank mails Ritter a payment on your behalf. It could take up to seven days for Ritter to receive the payment.
