pdfFiller scores top ratings on review platforms
On a learning curve,so it has been slow but I really like the ease of putting in my own form and filling in my data. Helps with creating readable Dues Notices
It's really convenient, I've been using it to fill out paper applications since I don't like filling them out since I have dysgraphia. I have some slight issues though, like I had one application where the check box would automatically do a cross and if I want to do a checkmark I have to drag it, which I also have issues with it aligning correctly. alignment isn't too bad, but it's slightly off. Otherwise I love using this site. :D
PDFfiller
This is a great app, I just can't afford it right now, that's all. It's well worth the investment if you can afford it though! Trust and believe that! They will give you a free trial period. So, try it and you will see! It really is a great PDF app!
Great
Easy to use the program, has a lot of great features & tools to use within the program. Will recommend to others. Love the timeline status for documents sent out or waiting to be signed
Don't like the reloading that the program does when open reopening documents sometimes. Overall not much to complaint about
Mobile and Remote Offices will LOVE this program
Love that I can send / receive faxes, sign documents, and accept payments ... It's a well put together process. Easy downloads and uploads, right at the tips of your fingers. Notifies you of faxes when received and easily downloadable to your device. Absolutely a 5 start program!
Excellent, user friendly software after you familiarize and master the features. The free trial is a plus as well because I will continue to use the software through subscription.
What do you like best?
I love the fact documents may be completed and signed electronically without the need to print, scan, and attach anything. It's so much easier, cleaner, and more secure!
What do you dislike?
The only issue I have had, which could certainly be user error, is that one of the links to an informational PDF (it's a read-only document) sometimes stops working. I am made aware of this when I send the link to someone new and the person responds to say an error message appears upon clicking. I have no idea why this happens and it's always associated with this particular document.
