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? The ease of deleting, adding and reorganizing worksheets in various units of study. What do you dislike? Sometimes when having to edit the same PDF to set it up to where there is only one student's report in a PDF at a time. It saved over the original document and I would have to reupload it. Recommendations to others considering the product: None, just that it can be a huge time saver for a teacher being able to edit PDFs for the classroom. What problems are you solving with the product? What benefits have you realized? The big one has been being able to send individual progress reports to students. Our gradebook system does not save them in separate PDFs, it saves them all in one so being able to use PDF to separate them and save them individually saves me time.
