it was not clear when I began my document that there would be a charge. I don't plan to use the program long term and would appreciate the option to pay for just one month without automatic renewal.

What do you like best?
The ability to create a document, upload a document, search and find document files, edit, and then fax or email to anyone anywhere right from the convenience of your laptop anywhere in the world. All documents created are saved in your account for return access, and activities (fax, email and receipts for delivery) are also recorded and saved.
What do you dislike?
So far I have not discovered something I do not like. I have uploaded, created, searched for online documents to use, and both faxed and e-mailed documents without an issue.
What problems are you solving with the product? What benefits have you realized?
Can work and send from home, work, on the road. No need to hunt for a fax service / company; no need to leave where I am at to go fax a document; can work and send documents in the middle of the night right from home or while on the road; have been able to search and find online documents and upload into account for editing use; easy to share documents via PDFiller; you can send documents to anyone with an e-mail address - your recipient does not need to leave their laptop either!

What do you like best?
I enjoy the way PDF is easy to use and allows us to send out documents quickly. We operate a few different locations remotely and we are able to send out important documents require signatures in less than 5 minutes! Support is great when needed but we seldom have any issues.
What do you dislike?
There are not many issues with it. It would be nice to be able to copy/duplicate documents prior to merging so we do not have to upload them once again.
Recommendations to others considering the product:
If you work remotely, I highly recommend this program. We love being able to email employees and clients in a matter of minutes for documents requiring information on their behalf.
What problems are you solving with the product? What benefits have you realized?
We are solving travel time and time with paperwork with all of the documents be readily available with just a click. Prior to PDF, we were having to meet with new employees for paperwork. Now, we are able to email them and have them sent back for processing. Our time is being used in a for efficient manner.

Absolutely worth it! Wonderful program. Slight learning curve, but then it's off to the races. Worth it if you are editing PDF's on the daily. Great save, download and share options all at once. Thank you for a great program!!
