The ease with which you can use it. I like that its so customizable in terms of how it works for my business. It's simple to get started but also easy to expand once it's running. Not much dislike about this software. If you are looking for a great way to organize your finance data and be able to manage multiple clients all in one place - then look no further! At this point, I have not had a single issue with the product. I am sure there is something out there somewhere but i have not hit upon that yet. I am able to quickly pull up invoices, payables, etc. as I need them. This saves me tons of time since I do not have to go digging through paper files or email threads when I need something.
