Greetings, SLT80.

I'm here to share information about the error you're having when applying vendor credits in QuickBooks Desktop (QBDT).

The reason why you're getting these error messages is that, currently, Bill Pay doesn't have the option for partial payment. But as a workaround, you can create separate bills of lesser amounts, or edit the total bill amount and select Save and Schedule Payment.

For the steps on how to do it, you can refer to this article for more information: Pay bills online from QuickBooks Desktop. This also includes details about managing the Bill Pay feature in QBDT.

In case you need it, I'll also add this article that tackles removing/unapplying vendor credit in QBDT: Remove or unapply a credit from an invoice or bill.

You can also visit our website for more tips and other resources you can use in the future: Self-help articles.

Please know that I'm only a few clicks away if you have additional questions about this or anything else. I'm always here to answer them. Keep safe.
