Hello everyone, how to maintain a single supplier account balance for multiple branches of the same company in quickbooks online ?

Hi there, Vel5. 

Thanks for choosing QuickBooks as your business partner. I'd love to help you with your concern.  

In QuickBooks Online, you can create location tracking that you assign to transactions. This lets you track account balances by department, business office, or location, separate properties you own, or any other meaningful breakdown of your business.   

To turn these features on, follow the steps below:

1. Tap the Gear icon and choose Account and Settings.
2. Go to the Advanced tab and pick Categories.
3. Check the Track Locations to turn on class tracking. 
4. Select Save and then Done.
