We truly appreciate the sigma tax pro team from software to tech support. our rep tamara is absolutely amazing from our first call to every time we need tech support. changing software is a big scary deal but tamara kept us calm and informed and still helping us after we took the plunge. so far so good and we are grateful to have the chance to experience sigma tax pro because of tamara and our favorite tech supports arnold, darius and the rest of the team.
