Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates.

You also have the option of checking our QuickBooks App Store for apps which may be able to help you achieve what you're looking to do.
For the time being, you can enter bills manually and pay them.
