In QuickBooks Online (QBO), running a Profit and Loss (P&L) report will show all costs. However, if you want a detailed breakdown of your transactions, we can use the class tracking, tags, and location feature.
Here's how:
Go to the Gear icon.
Choose Account and settings under Your Company.
Go to the Advanced menu, and click the Pencil icon for Categories to see more details.
In the Track classes section, move the slider to the right to activate the function.
Tick the Warn me when a transaction isn't assigned a class box.
Under Assign classes, select One to entire transaction or One to each row in transaction.
