It's easy to use, I do like it; but it is a little expensive, $80/year is a lot. I use it maybe once or twice per month. I think you would have more customers if it was less expensive.

Something went wrong, when I was filling once it stopped me suddenly. It saved the work, luckily. But I lost two minutes to restart my job, and this wasn't nice.

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!

Free trial Free trial is a great way to know and understand the capabilities of pdffiller it saves the files under a different name, but i dealt with it since i used the free trial

What do you like best? The ability to alter PDF files (add or subtract information) What do you dislike? The double sign in process takes up valuable time. What problems is the product solving and how is that benefiting you? As a real estate agent, I can tailor template forms to suit my client's needs.

I've been using PDFfiller regularly for over 2 years now, and it works wonderfully. I'm able to upload documents, add fillable lines, and get electronic signatures seamlessly. Customer service is also great - prompt and friendly in attending to any questions or issues. Makes running my business that much easier.
