Was looking for a fast PDF fillable form. I found it here. Even has e-sign which really makes me look professional. Always wanted to try it and now I'm glad I did.

So far it has worked for what I need. I wish there was a better price for non profit corporations. AZ Exotic Bird Rescue, Inc. is a 501c3 charity but I had to buy myself because of the cost.

I hate having to type in a verification code when I leave for a bit. I know it is fro security reasons, but I would really appreciate it if you did not make it type the code.

I've had a great experience using PDFfiller. Sometimes, I have single forms to complete, and I forget that I have the service. It's user-friendly. I need to make time to do a tutorial to learn more uses. Also, once I become better familiar, I'll be able to make referrals to sign-up for PDFfiller!

Great customer service
I signed up for a subscription when I really only needed to use it for one day. I canceled the subscription but it must not have gone through because I was later charged after a month. I canceled again and contacted customer service. They said the first cancellation must not have gone through but then refunded my money. That is why I will definitely use them again in the future.

If you ever happen to chat with Support…
If you ever happen to chat with Support for a technical issue --- Hope you get Paul.
Paul worked with me for nearly and hour trying to figure out why my form got skewed.
I shared out my screen with him -- he diligently and carefully figured out the problem and got it fixed.
Saved the day!
Kudos to Paul!!

I started with pdfFiller almost a week ago, and tried to get support on and off. The Live Chat didn't work, so I was emailing, but the emailing didn't really work as I would wait for a response, and when I got a response, I was working on something else. But the Live Chat did work today. The first person was trying to help, but I didn't know how to do a screenshot and he got tired of waiting for me to do it and ended the chat. Then, I got KARA, who was fantastic. She did a Zoom meeting and showed me how to do everything I want. I am so relieved that I understand how to fix my problems, and I was just about to give up until Kara got on the Live Chat. She was patient and informative. She is a rock star!

it is an easy to use software and worth the price, but with COVID and the gas issues, I'm tapped out.

The mathematical algorithm acts like a cipher, creating data matching the signed document, called a hash, and encrypting that data.
What is digital signature server?
In cryptography, server-based signatures are digital signatures in which a publicly available server participates in the signature creation process. This is in contrast to conventional digital signatures that are based on public-key cryptography and public-key infrastructure.
What is the purpose of signing?
The purpose of a signature is to authenticate a writing, or provide notice of its source, and to bind the individual signing the writing by the provisions contained in the document.
