Welcome to the Community, @accountant19.
I'd suggest following this thread, as my colleague @Catherine_B has provided the correct response. She gave very detailed steps on how to set up payment terms and conditions in QuickBooks Desktop Enterprise.
After following these steps, then you can pay the Bills. If you have additional questions or concerns, don't hesitate and leave me a Reply. I'm always here to help. Wishing you and your company continued success!
