When I first tried, there was nothing to tell me that I needed to sign in to my Intuit account. I was very frustrated that with four attempts, my payment didn't go through. Finally, I looked up my Intuit account and signed in with that. I use Intuit for TurboTax. I have never before used it to pay a bill. Nothing on the payment page says that I need to sign in to Intuit to pay a bill for Quickbooks, when I am not the payee.
