I've got you some insights on how to change the default department in QBO, @Fazfed.
Using classes helps track your transactions by departments, product lines, or any other meaningful segments in your business. So when it’s time to run reports, you have a clear picture of each financial health.
In QBO, you can change how you tag a class in customer transactions one by one in each row. To do this, here are the steps you can follow:
- Navigate to Settings ⚙ and choose Account and Settings.
- Click Advanced and then select the Categories section to edit.
- Choose Track classes.
- Select the Assign classes ▼ dropdown, then select One to the entire transaction or One to each row in a transaction.
- Lastly, click Save, then Done.
