I recognize the importance of having the option to pay multiple bills from one vendor through the ACH method, @mestrauss. 

Since this option is unavailable in QuickBooks Online, I recommend sending feedback to our product engineers about this idea aside from using a third-party application. They may add this feature in future product enhancements to make our program better and more efficient for you to use. Here's how:

1. Hit the Gear icon at the top, then select Feedback.
2. Type in your product suggestions.
3. Click Next to submit feedback.

While we don't have an exact timeframe for when this will be available, you can visit our Customer Feedback page to keep track of your suggestions.
