What do you like best?
As a beginner, I was surprised not only with the fact that PDFfiller was so much easier to learn and use than the Adobe Suite but also at the range of capabilities on offer! From my first use of this online program I found new pleasure in dealing with .pdf files. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.
What do you dislike?
The user Interface could do with being a little less busy. A streamlined interface and a compact "how to..." would take a 9/10 to a 10. It just needs some tweaking and it's perfect!
Recommendations to others considering the product:
In my opinion it is definitely worth spending the small amount to upgrade to the paid version!
What problems are you solving with the product? What benefits have you realized?
Administration issues generally...adding text, file conversion and commenting on documents...are all problems that I had to either pay to have done elsewhere or ask for an expensive subscription that was never in my budget and wouldn't be approved if I had asked.

What do you like best?
In our busy world, it is great to find a tool like PDFfiller to make things easier and to make sure private information is kept private. We no longer send attachments that can be read in an email that has sensitive information. Using templates has cut down our document sharing time! We now create a template that can be used over and over again. The big win in the form filling tool is the ability to add validation for the data entry.
What do you dislike?
The only complaint I get from users is PDFfiller documents are not showing up in their primary inbox. They have to search for them. We made it mandatory to check the box to send a copy of the email notification to our email address. This has made it easier to forward the email with the secure link to the recipient if they can't seem to find the PDFfiller email generated to them.
Recommendations to others considering the product:
Really take a look at your existing document and take the time to setup templates.
What problems are you solving with the product? What benefits have you realized?
In our office, we have tons of forms that need to have checkboxes and other types of validation done along with making sure it is easy for our users can easily sign the documents. PDFFiller provides the validation we need for our users to fill out forms properly. PDFfiller has multiple ways for users to sign electronically whether they are on their mobile device or their laptop; signing electronically is easy for them.

What do you like best? I like the ability to electronically sign documents. What do you dislike? I wish I was able to edit the text in documents without the formatting getting messed up because it only allows for the addition of new text boxes or adding to existing ones which causes the formatting issues. What problems is the product solving and how is that benefiting you? It's solving the issue of having to print out and fax documents which can be time consuming. It has really benefited my company to be able to sign and send documents electronically making for a smoother more efficient experience.
