This is an excellent program that has helped my business greatly with tax calculations for our clients! I love how easy it makes calculating taxes, as well as entering data into this software to help us make sense of what we are doing each year in terms of sales tax owed by customers/clients. The reporting can be very detailed - but sometimes there's too much information being given at once which may not always be useful or helpful (it would have been nice if you could just see one line per customer instead). We use it daily here so having everything up front helps ensure accuracy all around. It allows me to enter transactions quickly without needing any additional staff members helping out because they know exactly where things need inputting from previous years' reports.
