I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.

What do you like best? This program makes it very easy to enter data into pre-printed forms instead of using a typewriter. What do you dislike? Sometimes there will be a data box over another data box and it makes it difficult to change information. Also, when you highlight and change or add to preexisting words the formatting changes and you can not change it back to look like the original What problems are you solving with the product? What benefits have you realized? Not having to ever use a typewriter is the best benefit. Having all of my previous files stored is highly appreciated.
