I uploaded the app to my server and must say that it's a great start. Have you thought about adding employee time tracking for invoicing purpose? As well adding dates to the time activity / description on the invoices? Keep up the great work!
Thanks Corey for your compliments, working hard to improve it every day. Non-core accounting features such as projects, time tracking etc. will come as apps, free or paid.
We aim to open the App Store by the next week and for sure that all developers will be able to add apps.
Perhaps make an app that connects to some time tracker like toggl.com that has a great API and lots of other connections?
