Mostly good - had a little difficulty when the app decided I could only answer 1 category when I needed to respond to all 5 subcategories of a question. Also, messed with the date - it changed to a different format.

Our company is using PDFfiller for legal forms we need to file a Mechanic's Lien and have been able to do this by ourself without the aid of an attorney which is quite a savings. The forms are accurate and legally binding.

It.s a verry usefuly app, but i think is a little too expensive! So, please do something with the prices! We are glad to work with you! Thanks for your work.

I like the program It is not too complicated. The monthly fee is a bit too high I am not certain that I will be able to keep it past the free trial period. $20 per month is way off the mark; unless you have lots of cash flow. Just seems like $6-$8 per month would be more in line with the value of the product.

What do you like best? The site is very easy to use. The layout and design make it very simple to choose the best option for formatting documents. Choices for template or regular document helps to organize which docs you need to reuse. Even if you are not experienced, the options to choose from are so clear, you cannot make a mistake....and if you do, you can fix it very simply. What do you dislike? For me and my business purposes there is nothing wrong with this site. It is perfect and has made my business practice so much easier. Recommendations to others considering the product: Best program for editing documents, reduces additional work time creating new doc, great advantage with template option. If you are considering a program that will effectively improve your ability to create, organize, and edit important documents pdFiller is the best choice! What problems are you solving with the product? What benefits have you realized? I am in the field of Special Education as an administrator. This year with COVID-19, the difficulty of having documents signed, changing information and moving paperwork quickly has been a real challenge. With pdFiller, I have been able to address any paperwork issue that arises in an instant and then get documents back out for a new signature, or an update of information. This has saved me this year and helped me to meet all major and important timelines.

Pdf filler is a company with a ton of integrity and cares about its clients Pdf filler is a really great company that has great morals. I signed up for the free trial and forgot to cancel before it auto renewed for 1 year. With Covid impacting my commission based business, spending 120 dollars for pdf software is not something I can afford at this time. The customer service rep Rachel not only refunded my purchase, but did it very quickly and professionally. Obviously I forgot to cancel and this company could of held my feet to the fire as it was my fault that I did not cancel the auto renewal that I agreed to and left my Google pay account for. However they did not do that. I will absolutely 💯 use pdf filler again in the future if the need should arise and would recommend it to anyone that needs to edit a pdf file in the future!
