What do you like best?
PDFiller is ultra-convenient and super-easy to use. It's in the cloud, so it's easy to access. And it has a vast array of features. Storage is a cinch, whether on your hard drive or in the cloud.
What do you dislike?
I can't think of much that I don't like about the program. There might be a more direct or seamless way to save documents to Google Drive, in terms of getting them straight into a particular folder instead of just onto the Drive, but that's a minor issue.
Recommendations to others considering the product:
Try it. You'll like it.
What problems are you solving with the product? What benefits have you realized?
PDFiller is a lifesaver when I'm editing contracts and related forms. The clarity of the input and the ability to maneuver the text around the document is a huge plus. Line-outs and erasures are a breeze, making for "cleaner," more legible documents.

What do you like best?
PDF filler is very user-friendly. My favorite features are that it saves your docs. This makes it easy to keep editing docs that you use over and over. Also, when you use the erase feature, it keeps the eraser on the same line, which I could never do on my own! At the end, you can download the whole doc, or individual pages, this feature really helps and saves time on splitting the document with other programs.
What do you dislike?
Once docs are ready, the loading time to save can sometimes feel slow. Also, uploading the docs can sometimes feel slow. This is not a deal breaker, but perhaps something that can be worked on. I think there should also be a feature where you can upload docs one after the other for the same session, and it will merge the docs (or ask if you want to) and edit them together. It seems right now we have to edit each separate if they are not already joined, save them, and then go to another program to merge.
Recommendations to others considering the product:
Have an option to merge docs, make speeds quicker.
What problems are you solving with the product? What benefits have you realized?
When I get contracts, most of the time they are not complete to be approved. This allows me to add extra details and even sign the docs. I like the stamp it adds to show when the signature was made.

What do you like best?
We use PDFfiller primarily for tracking and completing registration forms for the advanced trainings we provide to mental health professionals across the country. Manually managing these forms was a nightmare as our business started to grow. Once we started using PDFfiller, it began incredibly easy and hassle free to monitor who was registered for which trainings and when. the integrated PayPal and Stripe systems make it super easy to allow customers to pay registration fees immediately and we are notified as soon as that happens. Also, PDFfiller offers a digital fax line. In today's day and age, we are completely wireless and adding a hardwired fax line would have been such a pain. For 10 bucks we are able to digitally send and receive faxes which is very helpful when dealing with physicians and other medical providers.
What do you dislike?
We have only had one real issue with PDFfiller. At some point a few months ago, we had some issues with the PayPal/Stripe payment integration. We were unable to send receipts to our customer which was rather frustrating for us and them because of the amount of money people spend to some to our trainings. I reached out to someone at PDFfiller and a manager responded the next business day and said they would get in touch with the team who handles that part to get it fixed. Though I did not hear back, within a week or so the problem was fixed.
Recommendations to others considering the product:
Do it. It is well worth the price for what you are getting.
What problems are you solving with the product? What benefits have you realized?
Sending and receiving faxes through this program is a lifesaver. I am able to access them anywhere at any time whether I am in the office or out of town. It's also a great organizational tool for tracking out "link to fill" forms.
