The service works well and is very convenient, however I was disappointed by the way I was able to complete an entire form but was not advised it was not free until the form was completed after spending a couple hours working on it. Since this is a pay service, the consumer should be advised immediately upon accessing any forms on an internet search. In order to preserve my work, I had no choice but to subscribe. Perhaps you should market a new service that charges by the document. I would have gladly paid for that up front. The service itself works very well.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL

I've had pdf filler for some time. I've had pdf filler for some time.Absolutely love it. Would not be without it.Definitely an A+. Everybody needs it businesses and individuals.

What do you like best? That I can mark up any pdf or create 1 new document from several. Also digital signatures, I work remotely and need this! Being remote, I need to be able to create or sign a form from anywhere and I can easily with pdf filler. I love the share feature as well, I can work on my end and my co-workers will have it almost instantly without having to print, scan and email. I work remotely, almost all from my laptop with no printer. This allows me to work from my phone or tablet seamlessly as well. What do you dislike? Not much, no complaints yet. Maybe the layout? Like where everything is, I click on the documents and then you have to specify where something is. Maybe a more organized folder system? When I share them, they should all be in the share folder, but for some reason, they're not always there. I am a very organized person and like everything in its own folder or file. I'd like a way to save everything to its own file and be able to find them quickly and easily. Recommendations to others considering the product: This is a great program, especially if you work remotely, highly recommend it! What problems are you solving with the product? What benefits have you realized? 1099 tax reports, our software only supports e-file and we are so small that we don't have that. I also love the share part, I'm able to work on my end, share it with my co-workers and they can have it almost instantly without printing and scanning, etc. I also love that I can take a few different documents and combine them to one, that is a great feature!
