I like that it is user friendly - has all of my invoicing needs in one place! It's very easy to use once you get used too its format/layout etc., but there are some things we have had issues with (that others may not).
Customer service can be slow at times as well so try your best if they aren't available when needed or don’t want their help right away!! We were able tto do our own accounting without having an accountant which was great since this program did everything else required from us anyway- just need time management skills now :D.
