The user interface is a bit clunky, but I highlyAppreciate being able to edit and modify simple legal documents in one visit. No long delays waiting on preparation!

It is expensive. You need to reduce the annual price. I also do not like the way the eraser works - it is either very sketchy or one has to save a doc and reload to erase something just done. Very slow and clunky

PDFfiller is excellent
I love how easy it is to use when filling out multiple page forms such as medical forms.
Price Point. If you don't do a lot of forms/saving forms you should pay a lessor amount.

Great to use especially working from home
I have been working from home and Sarah PDF has been trying amazing. It is very easy to use and the way I am able to merge my documents and download them is great.

VERY EASY TO USE PLUS ONE SUGGESTION
VERY EASY TO USE. THE ONLY THING I THINK NEEDS TO CHANGE IS THAT WHEN I SAVE THE DOCUMENT, INSTEAD OF SAYING IRS FORM 940 (OR SOMETHING CLOSE TO THAT) I THINK THE YEAR OF THE FORM THAT WAS WORKED ON. FOR EXAMPLE: IRS FORM 940 2019

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.

Great product and even better customer service
I used the product, which was excellent, once during the 30 day trial. However, through my own mistake in not cancelling due to e-mail mix up, I was enrolled in the full year subscription. I explained the situation to support and have been given a full refund. This has to be the best customer service and support I have ever received.

so far everything is good to use and very easy, I need to explore more but I do not have time. A little confused with the folders but I will learn very soon.
