pdfFiller scores top ratings on review platforms
So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!
The person who dialogued with me concerning my problem very patiently walked me through the steps of printing my tax form and everything was nicely resolved. Thank you very much, especially for your patience.
Simple and versatile. Since it is new "technology" for me, I must use it with some guidance to understand all its utility, so the tutorials that are included will be handy without having to go to school to learn it.
What do you like best?
PDFfiller is a great way for me to pre-fill documents that I use on a regular basis for my clients. By having as many fields clearly completed as possible, transactions that may have been held up due to illegible or missing information can be processed much more quickly. Clients also appreciate not having to do as much work! I also like the fact that I can use a social media signin for PDFfiller instead of having to create a separate user ID and password. It's one less thing that I have to remember.
What do you dislike?
Sometimes, I get frustrated by the "auto-detect" feature that highlights an entire line of a form. I'd rather use the text insertion feature and place text where I want it rather than have to edit the whole line. The other frustrating thing is having to make sure you're logged out on one computer before using it on another device in the office!
Recommendations to others considering the product:
I recommend PDFfiller without hesitation, with one caveat: only one sign-in is allowed at a time per user. If you use multiple computers at your place of employment, make sure you're signed out of PDFfiller on one computer before trying to sign on with the other. It will save you some aggravation. This is especially frustrating if you use the program on a desktop and a laptop and forget to sign out of the desktop computer before bringing the laptop home to work remotely. I did do a lot of research before deciding to invest in PDFfiller, and after my due diligence was hard-pressed to find an option with all of the features that I needed and at a price point that I felt was affordable. For the money, PDFfiller is a great investment for offices looking for ease and convenience with pre-filling forms. The learning curve is not very steep, and there is a lot of functionality for adding features besides text: check/"x" in specific boxes, highlighting, erasing, etc. I have used all of those features with little to no difficulty. Erasing is a bit of a science, with some trial and error involved in determining the exact size of the eraser needed for the job. Being able to move inserted text around easily and increase or decrease the font size as needed is a very helpful feature, especially if you want to call attention to certain pieces of information or make them stand out from the rest of the document. While I have not used the signature feature very often, I have found it to be useful in the rare instances that I have needed it. I have a copy of my signature saved in PDFfiller, which makes it very easy to insert a signature field into documents. Clients also appreciate this feature as well.
What problems are you solving with the product? What benefits have you realized?
PDFfiller is making it a lot easier for me to personalize and email forms to my clients, improving their service experience and saving me time and trouble. It's a huge convenience for me and much appreciated by clients whose handwriting is less than clear! The biggest benefit to me is having a library of frequently used documents that I can pull up on the fly, make adjustments and edits to a few fields, and have a new document ready to go in a matter of minutes. I've also been able to add information in the "white spaces" of forms I have created in the past, to include client-specific text, contact information and other items.

Paul at pdf was absolutely brilliant and very helpful. Cancelled my sub that was from my previous employer and refunded my fee. Couldnt of asked for a better person to help. Thank you!. Great asset to any company.
Very pleased with the customer care
I was new to using pdf filler and had a small technical issue with text auto deleting, so I hopped onto the chat where Sam helped fix the issue using screen share via a Zoom call, he kept me informed of what he was doing and the issue was resolved quickly. Sam also took the time to explain to me how to resolve the issue if I ever had it again and was friendly to communicate with, I am very pleased with the customer care, thank you Sam,
