First review
It works better than most others I've tried.It is sometimes a bit difficult to navigate as I dont use it too often. I dii have an issue with support, but they did finally undertand my query and they fixed it up, with a very good explanation.
I am not the most skilled with modern technology. As a startup NFP we don’t have the financial capacity to either hire, or contract with an accounting professional to prepare our year end 990s. I personally took it upon myself to do the necessary paperwork. I kept losing my work, and did not know how to save it without Word. I stumbled upon pdfFiller and decided to sign up. The retrieval and storage of my docs (either completed or still being worked on) is so simple now that even I can do it! The work has become easier thanks to pdfFiller. Thank you.

Great Functionality, Amazing Customer Support, Great Experience Overall
This is a great platform, very seamless and user friendly. It does cost a bit so it would make sense if you use it quite often. More importantly, amazing support - the online chat response was quick (!!!), customer support staff was so friendly and understanding. Overall, such an amazing experience using this platform. Highly recommend you give it a go!
Great for Work!
Great for work, especially if you deal with a lot of documents, forms etc. Good for making templates, stitching documents together, creating packets, getting forms out for people to fill. Great that you can fax your documents right from the web interface... makes life a lot easier.

working great so far, any difficulties are due to my lack of knowledge. My only suggestion is to hire one really dumb guy, and make it so its easy for him. Would you like me to send my resume'?
Ryan on the Support Team was extremely helpful and patient. He walked me through all of the steps to complete the form to my satisfaction. Thank you Ryan for teaching me!
