Yes, it has the same process when deactivating your client's job in QuickBooks Desktop. 

Let me show you how: 

1. Go to Customers, then click Customers Center. 

2. Proceed to the Customers & Jobs tab, then select All Customers. 

3. You'll see an "X" for inactive customers. 

4. Double click the Job to open the profile. 

5. Put a checkmark on the Job is inactive box, then click Ok.

Please keep in touch if there's anything else I can do to help you succeed with QuickBooks. I've got your back. Have a great day!
