Love this program! It allows you to download any document and make it your own. No more handwriting which leaves room for errors. The only part that confuses me is the saving of a document to be used over and over... haven't quite figured that out yet.
Jack
just started using the product and it works very well. The only thing is that I will use it for the forms I need to fill out and then will cancel since I won't need to use the product after 30 days. You should have a one time fee.
William
What do you like best?
I love that I don't need to hurt my brain trying to learn how to complete a simple task on PDFfiller. Everything is right where I need it and very easy to use. All the functions I need are right at the top and do exactly what I would expect. I like that it is web based and that I can access save documents anywhere if I am not at my computer.
What do you dislike?
I honestly cannot think of anything I dislike. I did some research before using this program and it fit my needs better than anything else.
Recommendations to others considering the product:
This is a great product for anyone who does not have access to a employer issued PDF document editor. It has all the functions of their competitors however I find it much easier to use and navigate.
What problems are you solving with the product? What benefits have you realized?
I don't have access to document signing software through my employer. So now I am able to create fillable PDFs, Sign and Date documents without having to print out and scan into my email. It makes tasks quick and easy.
