One bank account, for personal and multiple sole proprietor businesses

Thanks for visiting the QuickBooks Support page, @lkarch.

Allow me to share some information on how you can separate transactions for each departments or businesses in one QBO account. 

For this, you can tag your transactions using the Class or Location tracking feature. This way, you're able to identify the transactions easily just by looking at the reports. These are the steps to enable the feature:

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

Once set up, you can assign these class  or locations your sales or expense transactions. See this example:

Once you have the transactions tagged, you can open any reports and filter by Class or Location. To learn more about how this features work and how to use them, check out these links:

• Set up class tracking.
• Set up and use location tracking.
• Video tutorials for QuickBooks Online.

You're welcome, @lkarch. It's our pleasure to help. 

I'm here to share additional information about class tracking in QuickBooks Online (QBO).

You must be subscribed to either QuickBooks Online Plus or Advanced to use the class tracking feature. This is why you don’t have the Categories under the Advanced tab in your Account and Settings. Refer to the following link for more information about our plans and pricing: Intuit QuickBooks. 

After choosing the plan, you can go to the Billing & Subscription tab to upgrade your subscription. Check the following steps:

1. Go to the Gear icon ⚙ and then Account and settings.
2. Click the Billing & Subscription tab, proceed to the QuickBooks Online section, select Upgrade your plan.
3. Review the available plans and then select Choose plan.
4. Follow the on-screen steps to upgrade your plan.

Check the following article for more information about upgrading or downgrading your current QBO subscription: Upgrade or downgrade your QuickBooks Online subscription. 

To know more about turning on the class tracking and setting up your list after upgrading your subscription, see this article for detailed guidance: Get started with class tracking in QuickBooks Online. That will also show you run reports and budgets for each class you have.

Here's a guide that can show you how to adding, deleting, or restoring a class in QBO: Create and manage classes in QuickBooks Online.
