I was very upset at the beginning but after contacting customer support the problems were resolved and and I am happy I was able to complete my forms for my disabled grandson.

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.

I am in a struggle with the Home Office. I have to fill out multiple forms repeatedly. I bought Adobe but it did not work. This software is very straightforward and I am sharing the document with my Barrister, which saves me money, time and avoids confusion

very easy to use It is very easy to use, very self explanatory. If you could include an electronic signature platform or integrate one like with adobe sign or some other document signature software would be great.

A wonderful tool for small business Filling and sending forms is extremely easy, other people can sign into the account and use it. It makes filling out forms a breeze, no more handwriting. It's very simple to use, allows good organization and many ways of printing or sending the completed form. The E-Signature is a bit funny but that's my only complaint.

I really enjoy this app. I would like to learn more on how to download documents from my desktop and personal files in addition to documents on the web.

Very easy and intuitive, the learning curve is very small. Tiny differences in the drawing between what you see on the screen and in the printed document.

Edit and create PDFs easily If you work daily with PDF documents, this is a must for you It has a lot of PDF Tools in one on the cheapest plan Maybe they can unify the first and mid tier plans. They don't add a lot to the mid tier plan to increase the price. It just don't worth it
