Stop hesitating about whether this product will meet your needs, it will! Trust me. Act on your intuition and just try it. You will not want to stop after that have tried!
I think it is a better product that Adobe because of the price point and the many options that are available. I love the send to capture signature feature where this product allows you to get the signature of someone who does not even have the product at all.
What problems are you solving with the product? What benefits have you realized?
Digital signatures and workflow becomes so much smoother using this product. I have also used it to do registration of students now we are working virtually - parents file the form out and I get notifications that they have completed the process so I can then pick up the completed form. This has worked great for some business needs that surfaced because of the current pandemic! I love this product!
Quick and Easy
I needed it to quickly fill out some forms. Inserting text so it lines up with lines on the form is a little tricky, but other than that, pretty straightforward. Would definitely recommend!
