Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

Its good for the most part - the downside is it doesnt open for me on the first try and it asks me to sign in everytime i need to print or save a doc. even though I pay for the service. Annoying that it doesnt recognize me when I use the app.

Works really well with the exception that the margins or line spacing cannot be change to accommodate specific printer. Alignment can vary depending on the printe

I love to be able to use the pdf filler app much easier and it has become very important for us in documents we need to fill out and sign and send. I would like to see some ease in the selecting the editing of a document, can the display of boxes for each section be less overlapping each other, this may be difficult to do. Sometimes when you have a saved pdf document you do updates rather than create a whole new document, we use them as templates. Right now the easiest way is to create a document in Word, save it as a Word doc and as a PDF doc. Which is okay, often, time is a factor and to quickly update a pdf file would be faster. Thanks for listening.

What do you like best?
I can send as many documents out for signature as I want. No restrictions. I used to use Adobe, but they had a cap on the amount of documents you can send for signature. When I tried to get that upgraded, they had outlandish prices for this same service. With PDFfiller, I can send all the documents I want and I'm also able to save all of them securely.
What do you dislike?
I wish the PDF conversions didn't come out like pictures. When I convert a PDF to Word, it always comes into Word as a picture instead of being able to edit the document. As a recruiter, I receive a lot of resumes that need some work before we can submit them to clients. I still have to use Adobe for this function, so now I'm paying for two PDF programs. I can't just stay with Adobe though because of the above mentioned issues.
Recommendations to others considering the product:
If you need eSignatures, this is the program to go with.
What problems are you solving with the product? What benefits have you realized?
Remote onboarding is a breeze with PDFfiller. I am able to send HR documents to people across the country and still get them to work on time. I'm in VA and have to get employees to work in all states across the country, as well as oversees. We have to get documents to them for signature and faxing doesn't always work. With PDFfiller, we can send anyone any document and get it back fully signed by them. It's truly wonderful.

It was great to know that I can fill in… It was great to know that I can fill in and sign documents without needing to print and scan. This is amazing!

The products are awesome and have been essential to the success of my business! The forms are very easy to access and to use. The ability to have access to such a variety of forms especially IRS forms. The freedom of use to so many forms and the ability to upload your own created forms far exceeds so many other products that have so many limitations on the use of their products. My only complaint is that sometimes it is a little difficult to find certain forms that you are looking for but it is usually remedied rather quickly.
