Hello there, menotyou. Let me help and share some information about the declined payments.

It's possible that your bank is sending you an update, which explains why the funds aren't going through. You can check with your bank for any alerts or notifications regarding those declined payments.

Also, I recommend reaching our QuickBooks Support team using the steps provided by my colleague AlcaeusF above. This way, our team can investigate further why you are unable to process those payments.

Let me add this article for future reference: Pay bills in Online Bill Pay.

You're welcome to comment below if you have other concerns or follow-up questions about processing vendor payments in QuickBooks. I'll be around if you need me. Enjoy the rest your day.
