Thanks for the clarification, John. I'm here to provide details on how Bill Pay works in tracking your payments in QuickBooks Online (QBO).
Currently, the Bill Pay function won't split transactions by location when paying multiple bills simultaneously.
Furthermore, QuickBooks stores data per transaction. Thus, if you pay multiple bills with Bill Pay, the amounts won't be split by location. So to monitor your expenses by business location, I'd recommend running and customizing the Purchases by Location Detail report. Go to the Standard tab in the Reports menu to do so.
Moreover, if you wish to know more about how you can use QuickBooks Bill Pay, please see this article: Learn about QuickBooks Bill Pay for QuickBooks Online.
