Hello BSuzyB,
I appreciate you letting me know the error you're receiving when trying to apply bill payments to your open bills. I can see how this would slow down your workflow and I want to make sure you're getting the help you need for sorting this out.
Because of the message you're getting, we'll need to clarify what's going on. It sounds, for instance, like you may be using some sort of bill payment processor. If that's the case, you may need to follow up with your bill payment processor in order to troubleshooting this issue and find out more about resolving it.
Even if it's a regular payment through the Pay Bills feature, I recommend getting in touch so we can take a closer look. You can find the details about reaching out in our Intuit QuickBooks Desktop software support policies article.
Don't be afraid to give us a shout!
