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.

ONE OF THE BEST PDF FILLER'S IVE USED… ONE OF THE BEST PDF FILLER'S IVE USED SO FAR. SOMETIMES THE FONT LOCATION/SIZE WILL PRINT DIFFERENT THAN IT APPEARS ON THE SCREEN BUT AN ADJUSTMENT OR TWO WILL TAKE CARE OF THAT.

great customer service - sam great, easy to use, saves us a fortune on an extra phone line for a fax. Great customer service, I always use live chat and get answers and resolution within a few minutes. I have only had to use support 3 times in a year because the program is so user friendly.

Easy to use for 1099 filings Use for 1099s and other tax filings. Used this product for 1099 filings.. simple and easy to use except for ability to make edits (address changes etc.) once filed. Once a 1099 is filed, program does not make it easy to go back and edit a document. Also, any updated filings are charged another filing fee, which seems excessive.

PDFfiller was easy to use. PDFfiller allowed me to edit and submit my application easily without much effort. PDFfiller allowed me to move the curser to start typing over the form questions. While this was not a hindrance it did take time to get the curser back to where it needed to be to complete the application. This small flaw was not enough to prevent me from using the application.

Was OK after had a chat. I plan on keeping PDF filler after the trial period ends for 1 year so I can do my 2024 taxes done before the renewal date. If you have or willing to have a 3 month subscription from February to April I would be interested. Joe Mastro

Tons of functionality for a great price. Excellent customer response time. Feedback: when using the "home"/"end" keyboard buttons, it immediately takes you to the top/bottom of the form instead of beginning/end of the text box you are editing. Just an unintuitive and weird feature. Also, it would be great if there was a way to save LinkToFill settings so that they can be applied across other documents. Overall really happy with this product!

Only used the free trial = it was easy… Only used the free trial = it was easy to use; however, I cannot afford the price per month since I very rarely use the product.
