Overall easy to use, however, there are instances where the edits on the pdf become warped, other times its difficult to remove words or characters. There should be a save option versus a Save As, as that navigates you to another screen. Or have an auto save option. Overall good program but still has small defects.

Pretty straight forward but when you want to print multiple forms of the same type I don't see a way to easily clear the info, I have to overwrite or clear each field manually. Thank you, Fred McFaddin
Fred M
It took just seconds to send my agreement for signature. The customer experience inspires confidence in the security of the transaction and gives a good impression of my company. It is far better than the old - email it, print it, sign it, scan it, email it, "did you get it?"- approach.
Greg D
What do you like best?
I can take forms from online and my computer and can easily and neatly fill them in. I also love the form creation feature.
What do you dislike?
Learning to create forms is much harder than expected.
Recommendations to others considering the product:
Great service. Uploading and using forms is intuitive and easy. Allow time for learning if creating own forms.
What problems are you solving with the product? What benefits have you realized?
I mainly use it to complete and store forms. I plan to use it to create forms in the future.

Is been easy to use and edit to change documents or add to the document I am disappointed that I was promised 60% discount but you charged full amount
