The UI is outstanding and very effortless. Very impressed. My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun. Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

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.

The platform is sleek and elegant and allows you to work and manipulate PDFs in the easiest of forms. Of all the programs I look into, PDFFiller is the one I found the easiest to use.
