its good so far however I ordered it because it said it was $10.00 a month and it turned out to be $30.00, I guess that's only if you pay for the year it would've been nice had that been made clear before I put in my cc info

Works great with laptop, but Was time consuming and difficult to work on IPad. Had to switch to my laptop in order to speed up the process and complet the job.

It has made work much easier. In the legal field we deal with a ridiculous amount of documents. Many IRS and government forms require some PDF filler, Adobe Acrobat does not do the job PDF filler can. To be able to access my docs from anywhere is amazing. The email, sign, fax, and all the other features make it actually fun.

Over the top excellent customer service
First and foremost i want to express the excellent customer service i received from Daniel yesterday evening to the wee hours of this morning. i couldn't figure out how to correct or update a form and my computer literacy was no where to be found. I ask Daniel to please have patience with me and he went above and beyond my expectations. Daniel not only spent hours on trying to help me figure out the issue he also walked me through how to send him a screenshot of the issue! Not once did i ever feel rushed or uncomfortable especially when i wasn't able to follow his instructions. He not only walked me through fixing the form; he also helped me fill in some fields i was unable to do. The most awesome experience was he stayed on the line with me the entire time!!! This is the kind of customer service that is such a rare commodity and i was blessed enough to be on the receiving end with Daniel. He is absolutely an asset to this company and greatly appreciated.Warmest Regards;Rhonda Wright

Allows PDF to be edited
My overall experience with PDF filler has been convenient, and also allows me to fill in PDFs without having to print them out.
What I like most about the software is the storage content which allows you to save PDFs into your device and fill them out later.
I have not used this offer enough to find any dislikes, but it is very convenient for any business owner or even educators who need forms filled out electronically.

I liked the idea that I can modify a document with ease, but the yearly rate for educators is too much. I probably would have continued if I was given a reasonable monthly option. I do have a few subscriptions that I keep on a monthly option. So, keep that on mind when you are working with teachers.

Great customer support
Great customer support. I forgot about a 30-day free trial period because I didn’t use the app after registering and checking it only once. They took the money for the whole year through PayPal and when I explained the situation they helped me with the cancellation of my subscription in a half an hour. They gave me the whole sum of money back.
