Very easy program to work with and edit if you need to make changes and also cost effective, you don't have to pay the realtor half the rent by doing it yourself.

Fan Bloody Tastic on my CHROMEBOOK, nearly real time and it would be 5 stars. Realtime not yet available in this part of Australia. PERFECT fit for 100% cloud and paperless. Love it, just re thinking it and it is now totally 5 stars. Thanks :)

I find it so much easier to edit documents, and save for later. Being able to share and easily find them. As well as changing page lay outs for presentations too.

So far all worked really well, the only thing that could be still improved is to have the possibility to change the font size, when filling in a document

EASY like 123 having being able to come to this website , find the court document i need , and fill it out all at the same time has been life changing for me lately. i am able to clearly see what's written, understand it more, and also once i'm done implementing my information i can print however many copies i need without leaving home. This makes it a breeze when trying to look for court documents that you need.
Latoya Higgins
What do you like best? The templates are really helpful. It can automatically be saved with new information. What do you dislike? The signateure date and initialling has to clicked for each time. Would like to be able to just click the option and repeat that option several times without selecting it. What problems are you solving with the product? What benefits have you realized? Can send out contracts and paperwork. Re-formatted the paperwork to be filled out electronically and it's much clearer.
User in Architecture & Planning
What do you like best? Easy to navigate, loads quickly. I usually don't have a lot of time in the field to wait for loading. What do you dislike? Once I was proficient in the navigation, I was good. What problems are you solving with the product? What benefits have you realized? I get a fast turnaround on documents that need signed. I can also verify that the documents have been signed while out in the field.
