Although I initially had thought this was free, the overall experience is a positive one. The insertion process could be initially a little more self-setting / precise but overall good to use for my purposes

Loved the fact that it popped up in Google with the DOT form I needed, and allowed me to fill it out without any issues. The 7 Day trial is great and I will most likely keep for the year, due to the ease of adding in forms as well. Thanks

I was able to edit the pdf…
I was able to edit the pdf appropriately. When I converted to a word document, the places I had checkmarks in the pdf did not align properly in the word document, but that's really the only issue I had.

Great product and full refund when cancelled before trial ended
I took out the trial and paid 2 x €1.25 installments.
I used the product which was the best I found especially given you can edit PDFs with it.
I cancelled after a few hours and both payments were refunded as promised.
I would have been happy to pay a single use fee for this service but the subscription is too much for my once off use case

What I really like about the program is…
What I really like about the program is that we have a lot of issues and it was able to handle them all! My husband plays music at church which is a standard business. He is opening an LLC which we need to do several forms which most places do not handle including the 1120s, the k1, and so many others. The pdfFiller has handled them all!

I am a data manager at a school and this program has made my job a whole lot easier when it comes to asking for student records. This also helps when my fax machine wants to be lazy lol the five stars are definitely not enough!

I had to start over, from hitting the wrong "back up", but have it okay now. I don't expect to need it again, but this software made it much easier. Thank you!

Ryan on the Support Team was extremely helpful and patient. He walked me through all of the steps to complete the form to my satisfaction. Thank you Ryan for teaching me!
