AWESOME ALTHOUGH I THOUGHT I WAS GETTING A FREE TRIAL BUT NOTICED I WAS CHARGED $83.88 ON 5/6/14. DISAPPOINTING BUT IF I HAVE IT FOR A YEAR? I'M OKAY BUT YOU SHOULD BE AWARE. THIS COULD BE A PROBLEM IN THE FUTURE IF IT HASN'T ALREADY. BAD BUSINESS.

I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.

I'm a noob when it comes to computers, but this app helps me and I have been able to complete the court doc's I need to get $ back from my Ex. That's something I would not have been able to do without PDFfiller. Awesome app. David B Roseville Ca

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

I seek clarification about the 30 days free trial. I seek clarification about the 30 days free trial of using the services. The reply was prompt, direct helpful and highly satisfactory.

I liked the flexibility to edit and make changes in my document. Its rare to get something like this, especially for a pdf format. for me it made things easier as I was working on a pdf document and I wanted to make a few changes on it without converting to a word document.
ZIMBINI
Need clients to complete a form and/or sign a document; pdfFiller is the perfect tool. I needed a way for clients to access a fillable PDF via link multiple times throughout a process and give access to this same form to other team members to sign off on different stages of the process. pdfFiller made this very easy to do I was able to teach this to my team in 10 minutes so we were able to integrate this into our workflow. Easy to use, even if you have no experience creating fillable forms or verified digital signatures. It only manages very basic workflows, however, their sister app AirSlate does full workflow management, so if you need something a bit more robust, that's a great option!

IF YOU HAVE DOCUMENTS TO BE FILLED OUT… IF YOU HAVE DOCUMENTS TO BE FILLED OUT OR SIGNED, THIS IS DEFINETLY THE PROGRAM TO USE. ITS EASY TO GET AROUND. THE PROGRAM DOES EXACTLY WHAT IT SAYS.

It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe
