GREAT product! Nothing negative! I draw up a lot of contracts for my job and this website makes it much easier. This is very easy to use, the interface is very clean. I wish there was an app to support this product. A lot of times I am on the go and I need to fill out PDFs. It would be nice to have an app.

What do you like best? The app notifies me of when someone fills out my form. What do you dislike? The integration from the link in the email to the app on my phone. For some reason, there is a disconnect. Recommendations to others considering the product: If you have customizations and processes you wish to conform E-signature function in your documents, PDF Filler is a great tool. Great for contract-heavy and approval-required documents for our business. Great for folks who have medium to advanced level of word processing abilities and technical capabilities with graphic apps. If that's you, you will be a quick study. If you find it dificult to work in a Word document or Powerpoint or other types of programs, this app will have a learning curve for you. What problems are you solving with the product? What benefits have you realized? I cut down my use of paper and ink. I save time by modifying PDF's within the application. I can merge multiple documents. It has streamlined processes in our business to get paid faster and run more efficiently.
