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.

I love the features of the pdfFiller, however, I gave it a 4 rating because you couldn't precisely place the fillable icon EXACTLY where you wanted, like you can in Canva. I had to go back and correct my Canva templates to accommodate the PRECISE application. (They were circular designs, not traditional checkboxes.) If I had this option, I would have given it 5 stars.
However, when I do place my fillable icon in the precise spot on the first "checkbox" it does keep all the other checkboxes in a straight line down the document, and then on the next page it can be re-adjusted again.
So far, I am very happy with the pdfFiller and its features. I have plenty more applications to use it with in the future. SO-- I would give the program a 4.5.

Great customer service. My Employer needed a form off their website, and he had signed up for the subscription, the following month his credit card **** was almost a thousand dollars- so, myself, the office manager, I knew my boss only needed the one form he went on the website for, I went on the site,started talking to a live help agent, (very nice and helpful) I explained the situation, was asked basic information, and was told within 5 to 7 days the refund would be back to my boss's institution. Without any issues, or problems. This company is very helpful and has GREAT Customer Service! 5 stars plus! thank you!
