How can I set up and use project feature or an equivalent of it in QuickBooks Desktop?
It is nice to see you here in the Quickbooks Community, and I can definitely provide you with some assistance! A suggestion that has been made for creating this would be to use New Job, which is like a sub-customer under the Customer name. Secondly, for all entries where you use Customer, use Job level for expense entries, invoices or sales receipts, or QuickBook Time. From there, it will be separated under that customer. For example like this:
Smith and New Garage
Smith and Kitchen Remodel
Smith and Lakefront Home
Or it can be like Customer =Owner, Job Name = Pet name, Job Type = cat or dog, for a Veterinarian practice.
