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.

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.

Sam, on-line support did a great job!
I was very happy that Sam at the On-line Support, came on very quickly and helped me with what I needed and waited until I was sure it worked. I was also very happy that the program did "not" shrink the size of the words in the document like many other programs I have tried.
If it were possible to drag and drop email addresses from my email to the pdf filler I believe it would be easier. I'm writing them down currently and then typing in the information.

Had some difficulty aligning new paragraphs with existing ones. However with a little patience, I managed to do what I needed, great product.
