“My biggest fear was changing tax rates and me having to go into our old system and enter all of the new rates and worrying if I missed any new changes. With AvaTax, I no longer have to hope my accounting software is processing the taxes correctly. I know that it works and is always updated with the latest rules in my state. It’s out of sight, out of mind.”

– Tom Taubenheim, CEO and Owner, A/E Graphics
