Good day, @Mrjan.

I can share some insights about the project feature in QuickBooks Online.

Yes, you can use Projects as a replacement for the Class setup. The Projects feature allows you to organize and manage your transactions, time, and running reports.

Here's how to turn it on:

1. Click the Gear icon.
2. Select Account and Settings.
3. Choose Advanced.
4. Go to the Projects section.
5. Check the Organize all job-related activity in one place box.
6. Click Save and Done.

For in-depth information about the project feature, you can refer to these articles:

• QuickBooks Online Projects
• Projects FAQs

That should do it, @Mrjan. Keep me posted if there's anything else you need. The Community is always here to help you out! Have a good one.
