I was upset about a billing issue. Customer service reached out to me immediately and had my issue resolved in a very short period of time. I appreciate the way they handled it and followed up with me. Great customer service!

Great online pdf editor. Should have more features in personal level, a bit annoying to not be able to perform basic functions such as erasing sections of a document or deleting pages in a commercial, paid product. That is my only complaint though. Great software otherwise.
2016-04-11
It is intuitive, easy to use, provides adequate help for new users requiring guidance, and provides flexible outlets for PDF use. On the down side, I do not require a secure connection for my PDF work, and the lag in loading and saving my changes & files is distracting and unpleasant.

I hope to come back to this, as I have just signed up only a week ago. however, I had an unexpected event and need to tighten my finances. Great service though!

Having great difficulty because I needed to change details on a PDF file. It was so easy once I read your instructions! Thank you so much! Is there any subscription cost for PDF filler?

I am an old school person, but found your form so easy to use. I travel a lot so I will be using a lot. Thank you so much for simplfying the process.

Easy & simple to use!
Perfect for e-signing docs. Navigating the documents is easy & doesn't take you into weird places of the doc that don't need attention.
I don't see any improvements that need to be made, I really like this product.

*** ****** is literally the best *** Filling *** out there. ******. All the functionalities of *** filler are remarkable and make doing business a complete breeze. Unfortunately the Platform I use daily - is cheaper however - isnt as functional as *** filler. So I tried completing my need with them as I have used them in the past. So I signed up for the trial - attempted my documents - I failed; closed the window and forgot about the subscription. This morning I woke up and saw the charge, I couldnt remember what Email I even signed up with. I emailed *** ****** at 5 am and got an immediate response with an agent ready to help. They asked easy questions and were able to locate my account and issue an immediate refund. I dont think there are words to express how incredible and unmatched that level of customer service is. Thank you *** ******

What do you like best?
Being able to create templates of commonly used forms for client completion. Also being able to access legal forms (IRS, etc.) to complete through the system for commonly used forms for our Small Business Solutions. The notifications via email and the ability to save the completed forms to Google Drive for easy access. Being about to have a link to send to clients for specific forms based on their needs is extremely helpful. Being able to take the links and post on our website for easy accessibility for our clients. I love that we can embed the links throughout all of our communications for ease of use for client interaction.
What do you dislike?
Not being able to locate the signed documents in a central location, but rather having to access from the notifications for each document. The navigation of the system is systems challenging to locate documents that had been completed through Link to Fill process. I also do not like that we cannot edit information on the PDF, unless this is a service we are currently not utilizing with our subscription. I have to go into another program, such as Word or another PDF Editor software to make updates an then reupload the form to PDF Filler. The ability to make corrections within the PDF once uploaded would save me time and increase efficiency. The transition of the link from the published link to fill page and when posting in our practice management system requires an extra step to post into a web browser to get the full URL that works for clients to copy and paste.
Recommendations to others considering the product:
Consider how much time you spend creating forms, money you spend on postage, and storage for paper filing. If you're looking for ways to improve your workflow related to form completion for client interaction, you have to give PDF Filler a try. You will not be disappointed and will free up time to interact with more clients.
What problems are you solving with the product? What benefits have you realized?
The need to create customized forms for each client. Saves time during client communication to easily share a link via email, client portal or text message. Streamlines our processes and increases efficiency for team with access to completed documents. Great benefit for routine business operations with forms that we use daily for multiple lines of service.
