My experience has been wonderful. I paid a lot of money for a divorce site that would allow me to use fillable forms. It was frustrating from the beginning. I started using PDFfiller instead, and requested a full refund from the other service. They refunded my money. I have had great luck finding everything I need for this divorce. Your help support is great! I would certainly recommend this company/service to anyone.

It's pretty good. There is a delay from when I type till when the text appears in the text box.Also, I don't like have each field with a help box. I know I can X it out but it gets in the way when I want to go fast. I do like that it goes automatically from one field to the next such as with the dates.

Fill it out! Overall, I love when this is available to use for forms I need to fax or email. I love the feature of being able to fill the form out online. Very easy to use and beats having to fill in by hand, scan and send. I am not quite sure how to do this myself and have to ask IT to assist in making the form fillable for me.

Program is very user friendly. Able to properly prepare and submit IRS Form 941. Easy to use and instructions on usage is very user friendly. Cost to use the system is affordable. Ability to save documents is crucial to church finances.

The site was a little bit slow The site was a little bit slow, but it had tons of useful features, and I found the user interface much more intuitive than Adobe reader. I'd recommend it to anyone.

What do you like best? I like how easy it is to load my documents into pdfFiller & the multiple option for export when I'm finished. What do you dislike? Not a fan of the constant email verification especially since I've been using it for 3 years now & this is something just started in 2020 (it seems) What problems are you solving with the product? What benefits have you realized? I don't have a fax so its much easier for me to receive email documents, sign them with the signature feature in pdfFiller, and send directly to the recipient from the program. I get a notification, too, telling me my document has been downloaded. This has helped me a lot lately.
