Good start, but needs customizability.
I like the way it works for the most part, but it has some bugs. For example, some screens have two return buttons. If you pick the correct one, all is good. If you press the wrong one it returns to the prior screen without saving your changes.
The invoice generated is black and white with no way to set your logo (that I have found so far). if you need invoices, this is a start. Hopefully another release arrives soon.
