It beats my hand writing. I would be nice if it did the calculations also. But you can't have everything. I'll probably be only using this for my state tax. There on line program stinks.

Great tool for PDF mistakes Good experience, I really recommend this for people who need a PDF edit tool It' easy to use, few and useful settings that can really help fix a mistake or even save the document in a different way I couldn't find the go back tool for a minute but it's actually pretty simple and helpful

I'm computer illiterate and even I could easily use this It saved me time and money, thank you :) Easy to use and easy to understand format, it made me feel like a pro lol, and I love the feature of being able to download your copies to your computer in either a PDF or a Word file, personally I dislike PDF files but if you have to send or receive them this is the perfect tool to do it with. Have already recommended it to several friends and family.

What do you like best? That it looks professional, it is easy to use, and there are so many common templates to use which are always necessary, especially for a small business owner. What do you dislike? That it is always such a process to sign in if I am not at my home computer. What problems is the product solving and how is that benefiting you? It allows me to complete my forms needed in a timely manner and saving time for me is ALWAYS beneficial. I am more productive. Title for your review: Excellent site for completing and sending important professional looking documents.

Kara was VERY helpful Kara was very helpful, especially in suggesting we do a Zoom screen share, which made some problems I was having with navigation and document publishing much clearer. She should get a raise.
