The only issue I have is that old documents that I thought would be saved are not. That is my issue, however, and not yours. Everything else is great.

SIMPLE AND EASY TO UNDERSTAND FOR PEOPLE WHO ARE NOT TECH SAVY ITS GOOD BUT PRICE SHOULD BE MADE RESONABLE SO THAT MORE PEOPLE CAN AFFORD AND USE YOUR TOOLS. FOR PEOPLE IN INDIA IT IS STILL EXPENSIVE. IF YOU REDUCE YOUR PRICE, IT WILL BE AFFORDABLE TO MANY AND YOU WILL HAVE MORE CUSTOMER VOLUME IN INDIA THAN ANY OTHER COUNTRY. THIS WILL HELP YOU GENERATE MORE REVENUE.

JUST AS GOOD OR BETTER THAN ADOBE PDF AND CHEAPER Used for filling out electronic documents, easier than filling out documents manually and then having to scan them in order to email them. Easier to use than adobe PDF, at a better price. No complaints about this software as the time of me reviewing it, so far very content with it.

I've been very happy with this product! It has helped me tremendously file insurance claims and do work since my husband has been in the hospital since 5/30/20. I did the free trial but will be purchasing it for the year.
