Yes, I used them for Qb. It works perfectly . We was trying to use that for Proseries 2019 tax return, but it gave us a lot of headache. If I work on client A, and my employee will work on that client later. It will create another save, or we cannot locate that file in another desk. We don't have time to deal with it in a short time, so we decide to use Proseries network.
Hope it helps.
