I need to track revenues and expenses across multiple lines of business. Does QuickBooks Online Plus support profit and cost centers?

You can establish Profit and Cost Centers by enabling Class tracking feature in new QuickBooks Online Plus.

To enable Class tracking feature:

• From the Home page screen
• Select the Company Gear (top upper corner)
• Select Company Settings under Settings header
• Select Company
• Select/Double Click to enable “Track Classes On” under Categories
