PDF FIller was an answer to many questions. Our business is an industrial maintenance business. We have had to use PDF filler several times with applications and insurance documents. PDF filler made it easier. We liked how they explained everything we needed to know to fill in applications and other papers online without having to scan and download everything separately. I always thought it was my computer that was the problem, but with PDF filler, it doesn't matter what software is already on your laptop, you can work with any documents. Sometimes I would go duplicate a step in saving the document, but after a couple of documents, it was easy to figure out what I should do.

I needed to complete a form online and… I needed to complete a form online and pdffiller was the perfect solution. I was able to find my form, fill it out on line and sign it online. I had no issues.

Very convenient! Refilling forms is now a thing of the past for me, with this app I can make templates for reusable forms, it‘s also a convenience for my client as I can pull up forms in no time. Erasing was quite a struggle when I was assisting my coworker, it took a while to figure that I only have to adjust the size. What do you think about this review?

I will be back! I used PDFfiller to sign severance paperwork. I took the free trial and then THOUGHT I canceled it right away. When the charge came through, I was ready for a fight...but that didn't happen. Kirsten at PDFfiller's live chat was lovely and helpful. She even apologized for the mistake I most likely made. Then she asked if I was sure I wanted to cancel (a trained question). When I said that I didn't need the service, she didn't push and she processed the cancellation and refund right away. If/when I DO need a pdf filling service again, I will use them!

Top quality all round Only used the free trial for a specific task needed at the time and pdfFiller offered everything I asked for, unlike other services I tried. Very straightforward and accessible. Fast forward a month and I’ve forgot to unsubscribe. I see an email saying $180 dollars has been paid out. Of course, it was agreed upon, the yearly subscription follows the free trial. But I didn’t want the subscription, I hadn’t used it since the first day. And to be clear it was not for a lack of quality but rather a lack of necessity. But all I had to do was email the support team and even on a Sunday their responses were immediate, clear and thoughtful. I explained the situation, they saw my predicament and even though I was at fault, they did not hesitate to cancel my subscription and repay me in full. The money was back in my account just hours later. Superbly run business!!
