I've only done two documents, but so far I think it is a swell program! I have one more trustee that I'd like to add, will that cost more? We use the program for a charitable trust and we are unpaid. Thanks a lot, no matter what the answer is! I really like the program. MP

excellent, extremely professional and easy to use. Great customer service. Best money I ever spent on the APP Department. Recommended it to everyone. Hands down it is worth your time to investigate.

Overall, it was good.
Saying it is free is misleading.
I understand marketing, but I spent A TON of time filing out a document only to find out the only way I could retrieve it was to pay for a subscription which I would then have cancel to make it "free".
The other issue was that when the document was converted it shuffled page 2 with page 3 and the only way I could correct it was to upgrade the subscription. I would not spend the additional money when I print it and scan it back in the correct order. Again I'm sure it was an additional money making opportunity for you, but not worth the cost for me.

Definitely Useful
As I mentioned, it makes the mailing process much more efficient.
PDFiller allows you to create and mail PDFs easily, saving you the hassle of getting an envelope, purchasing a stamp, maybe having to go to the post office, etc. For me that has been its greatest strength. The PDF customization interface isn't bad, but it's not immediately usable. It takes a little bit of time to learn how to use it effectively.
Right off the bat: I would not recommend this software to someone who isn't tech savvy or doesn't want a bit of a learning curve, for example, employers I've had in their 50s, 60s, and 70s who don't really "get" technology. The interface is fine if you just want to sign a document, but is not particularly intuitive when it comes to doing simple things like outright deleting portions of text. Too many steps.

What do you like best about the product?
pdfFiller by airSlate saves me so much time when dealing with documents . You can easily share documents and ask for signatures via messages or even share them via QR code
What do you dislike about the product?
A bit tedious when it comes to editing the document. you would have to edit it in a word format and then proceed again with converting it to PDF format. It's a little bit too many clicks for my liking
What problems is the product solving and how is that benefiting you?
The ease of use is the major factor in using PdfFiller. It has help me communicate with the people I dealt with and send documents for their review and signature
