What do you like best?
In-line text, change font size, save options to name a few. Being able to quickly fill out insurance applications and having the text line up is amazing. I have been looking for this feature for awhile. PDFfiller is quick, easy, and has boosted my efficiency greatly.
What do you dislike?
The page fails when resizing text, and then you need to reload it. That is really my only issue other than when saving a PDF to my local machine, I don't need the indicator to pop up and tell me where to look.
Recommendations to others considering the product:
Sign up! You won't regret it. PDFfiller is easy to use, extremely helpful, and increases productivity dramatically. Great product.
What problems are you solving with the product? What benefits have you realized?
Easily fill out lengthy forms via pdf vs having to print them out and fill out by hand. We have been able to complete applications and fill pdfs faster and get them to where they need to go much faster.

What do you like best?
I like how easy it is to take a PDF and be able to type what I need to, change colors and fonts
What do you dislike?
I wish that the erase tool would be able to go in different directions, not just left and right but to be able to use it more freely to erase easier.
What problems are you solving with the product? What benefits have you realized?
benefit in using this for my business is keeping documents clean and not having to print them out hand write on them scan them back in and email it, I can do it all in PDFfiller and keeps my documents clean, and is a lot easier.

It was smooth and easy to understand. My only question or concern is. When submitting my corrected 1099 to is IRS via your site. I was not sure which copy it was sending. It did not give me an option. I hope the correct copy was sent to the IRS.

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

definitely easy to use. however some date fields do not have the "calendar" option, so you are forced to manually enter the date. That could be made easier.
