I like the idea that I can go back and fill in the parts of a report that I couldn't finish in one sitting. This will a big help to me in my newly appointed position.

Great, this website has allowed me to be able to document forms I needed in my current court case and save me tons of money from hiring a lawyer. Thank you!!!!

This was a great site to get my office free from all papers. When we need a document we just upload it out of our computer or one of our drives and fill the form. It is literally that easy and I am loving it.

It made a nice document. The only thing that is challenging is that you have to go line by line instead of having an option to change more than one line.

Good service
Good service. It's more than I want to pay. I don't use it enough to justify the price. If I need these type of services again I would return to this company.

Changed my small business capabilities
I am now able to manipulate documents and complete forms that I need to use on various government websites. This capability changes my small business and, as I bill for my services, gives my clients the absolutely best of what they pay me to accomplish!
I can't see any downside to this software. There is nothing I have tried to accomplish that I have not been able to do with this software.

Awesome!
If there is a way to add your logo I could not find it... then again I didn't look either so...this might not be accurate.
So easy to use. extremely user-friendly. The benefits are that you get to create any type of form you need and customize it to fit your needs. You cannot ask for anything better than that.

The formatting on this website isn’t…
The formatting on this website isn’t good. The page doesn’t load properly, which doesn’t allow you to find the options to cancel your subscription before charging you. Luckily, in the support chat, Thomas was very helpful and understanding.
