I LOVE THIS SERVICE SO FAR. IT HAS ALLOWED ME TO CREATE THE DEMOGRAPHICS FORM FOR TAX PAYERS IN THE LAY OUT THAT I ALWAYS DESIRED. THE BONUS TO THE LAYOUT IS THE PDF FILL IN THAT ALLOWS YOU TO INSTRUCT THE CLIENT RIGHT WITHIN THE CELL. THE SEND TO SIGN FEATURE IS AMAZING IT ALLOWS ME TO OFFER A FASTER SERVICE WITH OUT HAVING TO HAVE A PERSONAL INTERVIEW.

So far it has worked for what I need. I wish there was a better price for non profit corporations. AZ Exotic Bird Rescue, Inc. is a 501c3 charity but I had to buy myself because of the cost.

The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?

Fill in the Blanks! As per the 'Pro's' above, when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents........... Every had a pdf file or document that you can't collect text sections,OR fill in a form, or add notations or extend a document. I did, and often, and I wanted it to look professional as possible, be online, so access from off office meetings was available, and documents changeable in an instant. One that when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents. Then I found PDFfiller, it does that and more and I would highly recommend it, a reasonable cost for an excellent product that continues to update and improve its offering. Keep up the good work! A little bit cumbersome in remembering how to download a finished document, could be just me, but clearer tags or instructions might help

Glad to have it Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.
