Its been a good experience so far. Although I have only used the service approximately 5 times it has been an efficient way to produce some general documents.

It successfully sent a fax for me. I was able to upload forms that I needed from years past. So far, it has been exceptional. Will re-rate after a little more experience with it.

I struggled a bit when the form was completed because I failed to see where the "Print" button was located, but a rep from Customer Care (Paul) helped me and I was all set. Looking forward to exploring and using the PDF filler site frequently.

Easy to use, saves time Time utilized more efficiently, forms completed with step by step guidance, simple for beginners or working late hours, most documents are available in the library, folder organization, can add signatures all in one spot. PDF filler has a large library of documents, anyone can easily personalize templates, can prepare add signatures and finalize documents all in one step, saves time! It does not have version history. It automatically saves all changes, however comparing to old versions has to be done through downloaded pdfs

kara was great kara was great. I am an older computer geek who never got into such things as screenshots. Not only did kara patiently deal with my problem but she also helped me with her request of a screen shot. i have 2nd and 3rd level support at ibm on global WAN's so i have an appreciation for what Kara did for me. Please give her kudo's and preferably a raise for dealing with an older computer geek
