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 like to be able to upload multiple documents and then have the ability to rearrange them if needed, or remove, or even add to my entire document. What do you dislike? I do not like that the desktop extention frequently has errors, and continues to lag. I also do not like that the fax portion is uncustomizable. What problems are you solving with the product? What benefits have you realized? It helps me to add or remove specific line items, which I do not want others to see. It also allows us to add pictures to the PDF documents, such as signatures, and or stamps for notary.
