This is an easy software to use. The first time I didn't realize it was a "for fee" product. I am glad I stuck with it and paid to use it. I am just signed up for the month and my husband and I are filling out job applications. It is really convenient!

It does what I need it to, it saves others from having to read my very poor handwriting, and, since it saves the files, if I need to file them again next year, I just have to change a couple of dates, and "Voila!"

i love the copy feature so I can duplicate forms and just change the dates instead of filling out the whole form again when everything else stays the same.

Adobe for Life Overall, it's an amazing feature of the Adobe family that comes in handy for myself and especially in my industry where contracts are signed and requested frequently. So you're working on a project, job, whatever and you get a form that needs to be filled out, signed, and returned. It's a PDF file which is great because nothing can be edited off the original form. You're only responsibility is to fill it out and send it back, but you don't have a printer available, there's no fax machine around, and this form needs to be completed ASAP. The PDF filler is an amazing tool that gets the job done. Not only does it allow you to fill in information on any PDF file, it also allows you to upload your signature to docs as well. So while you can add your information to any pdf file, some of the files don't always allow for ease of filling out. For example, some forms allow you to type into blank spaces where words and information are supposed to go, while others have distortion issues and don't always allow for certain spaces to be typed into.

i was not happy with the Basic Plan being advertised for $8 per month and then subscribing and it suddenly being $20. I looked at some past notes from Sept. 2020 in my computer and it looks like I joined in Sept. 2020 and discovered the pricing being different than advertised, and I canceled then. Today I needed to sign some project documents and rejoined rather than playing around with a free trial of DocuSign that didn't offer what I wanted for variety in signatures etc. Giving PDF Filler a try. Will call CS to hear what their explanation is regarding what you advertise for $8 per month, only to see it is really $20. Evelyn Basile, Chicago

I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named **** was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)"

I think it is good however I already… I think it is good however I already see methods to improve it. I desire to fax a smart folder of documents I already created. This would be a facilitate faster communication of information as opposed to finding out how to merge the documents and then fax the complete file. All in all, I like the platform. If you may obtain DocuSign options, it would be nice long term perhaps. Many corporations and companies like to use DocuSign.
