I write reports for evaluations. Litigation has mandated that these reports be quite extensive. Handwriting them took hours. Scanning the forms into a pdf and allowing me to edit them is immeasurably helpful to maintaining my sanity.

Still learning my way around. While it is helpful, it is not the most intuitive interface. Not bad, but could be a bit smoother and easier to navigate around.

The Product concept is very nice the use of tools are simple. Things that I don't like are is that you are required to select Continue in Browser when click the Hyper Link, this for me is an unwanted and in needed step. The App I wish would allow you to search your fillable files, without the Link/Code or QR code you cannot use it. Would be more willing to use the App if this was a feature.

Managing the signature was difficult and took many attempts. Something near satisfaction was accepted. Otherwise, this app saved me time and made this task easier to complete. Thanks to PDFfiller.

What do you like best?
I like the ability to send to sign documents the most. I use it in my business daily. I like the features to organize my documents and to make templates. The templates are a life saver. Also, PDF filler has a large library of documents, anyone can easily personalize templates, can prepare add signatures, dates and finalize documents all in one step, saves time, LOTS of time!
What do you dislike?
I like it all. I don't have any complaints.I have used other document signing programs and they are way more difficult to use. No so with PDFfiller. The mobile app is not that easy to use as the (desktop) version. If I had to say Sometimes there is a delay from screen to screen. But that could be connection.
Recommendations to others considering the product:
If you need a document editing tool that does everything you can think of USE PDFFILLER it ROCKS! If you need to use this product to mark up documents and sign, try this product! I like to keep everything that I do 100% electronic, so with products like this, I am able to do so.
What problems are you solving with the product? What benefits have you realized?
I can get leases and contracts signed very easily. I like the ability to get clients to sign contracts and leases on their mobile phones. 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.

Such helpful customer support This is a great product but I only needed it for a short while, (1 day) but forgot to cancel my free trial, contacted customer support and they arranged for a refund right away, so very helpful.

Amazing customer service, very fast response time I was on trial with pdfFiller and it was really amazing. The best PDF filling software I've ever found. I even used the trial, forgot when it ended and then got charged. BUT I managed to get a refund after explaining my situation. These people are awesome. I definitely will be back when I have enough money.

PDF Filler Saver and Protector Great! Awesome software/product that is very helpful in the business environment. What I like most with the PDF filler is the ability to secure and password protect a very important document. I like sending documents or exchange with staff for faster and easier collaboration and this software helps us do that while making sure the personal information are protected. Nothing much as it serves the purpose that I am really looking for. I cannot think of anything that I don't like. I am satisfied.
