I like it- does what it says- easy to fill in a form. My local authorities keep changing their forms so everytime we spend a long time converting them to word files for editing, they become obsolete! Now, we just work with this weeks form and it doesn't matter if they change the layout! Perfect- no more time wasting with forms!
Nicola
So far I like the program, I cannot figure out how to select a line item (draw a box around it) and select all to delete. If I am missing something, please let me know. Thanks
Scott
It saves me time in messing with duplication of forms and figuring out the proper operating program. All you program is in PDF which is great. thank You PDF filler Lynn Harp

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.
David Nelson
Awesome service! helpful for customers Ease of use! Love it. I love that i can change forms and addresses. This has been a lifesaver for work purposes. I wish you had more options as far as fonts go and wish you had more options as far as font sizes..something to think about

Communication & follow through on point. Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.

I had a very complicated question pertaining to a credit card charge, (I didn't know which account within our company had incurred the charge, and therefore, couldn't track down a receipt) **** helped me reverse engineer the charge to find out where it came from. My company provides Customer Support for the Video Gaming industry, so I know the value of a positive CS experience. Way to Go, ****!
