What do you like best?
The software is very smart - it has a lot of formulas built into it to calculate tax correctly, to the point that it will catch things I as a user who knew how the calculation should be done, would not.
What do you dislike?
It was often slow, the formulas were often difficult to follow (not intuitive), which would require calling in to get support, which also had a long wait.
Recommendations to others considering the product
Utilize the support services - although there is a long wait they would almost always either have an answer or follow up to provide you the answer. Everyone I spoke with on support calls was very knowledgeable.
What business problems are you solving with the product? What benefits have you realized?
Business problems solved - preparing tax returns correctly
Benefits realized - being able to complete my jobs on time
