This is a total ripoff. Once they have your card number, according to the banks, you have authorized them to charge as much as they want. They charge by the minute whether it solves your problem or not!
I asked Progent to do a simple network of my 2 home office PCs and laptop. They sent someone who they later admitted was not a network specialist, who bumbled around for 4 hours and still did not get them networked. They charged me almost $900 and refused to reduce it!! They connected me with a 2nd technician later who seemed to know more and he got it temporarily working, but it didn't stick for some reason and they don't give any guarantees. I had to pay more to hire a local person with some integrity to get the connectivity working and find an actual solution.
Owen and Zennes were great for payroll support, but when I really needed them at tax time after my first corporate return went bad they failed me. I had to repeatedly ask for an appointment to review the return when I sensed something was wrong and panicked. Even after asking pointed questions about the area where the error was, Owen didn't check the work but just kept justifying it. I had to get another CPA to review it to find the $3,000 error, which was really disappointing and surprising given the good experience I'd had having BBV do my payroll and being very responsive. At the end Owen said it was their software at fault, which did not help my loss of confidence a bit. They did at least prepare an amended return to fix it.
