pdfFiller scores top ratings on review platforms
I had trouble with printing but being the stubborn person I am, I did not request help. I did manage to print after a while. When I did complain, they listened and made a correction on the bill. I'm quite happy with the program now.
Well I paid for the year then could not access a file I did the same day. Then I sent my accountant a file via attachment since he says "not technical" & could not open it in pdfiller file, so I sent as attachment so he could complete but he could not so he wrote it in now I have to complete it & paying him the same.
The interface has improved, but it is not perfect. I chose PDFiller because of its simplicity. I love that I can use it anywhere without having to install it in every computer I use. I wish it included a crop feature or the ability to modify the page size. I also wish we could delete previous files with the same name so that there is no confusion. There are several other little things, but these are the top major issues I've had.
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.
Just a few suggestions
I have used some other comparable products, but pdfFiller offers the online hosting that makes it super convenient for the user to fill out the form without having to download the form first. However, I have a couple of suggestions. I wish the pdfFiller could have the feature to automatically convert the raw entry data (e.g. phone number 1234567890) into the selected format (e.g. (123) 456-7890), instead of asking the user to enter it into the specific format. I also noticed the accident that some fields will be deleted accidentally when saving the edited version in LinkToFill. It happened several times to me when I was editing my file. Not sure if that's an internal bug or an accident from the internet interruption.
I love this PDF filler it is very easy…
