Very Basic Invoicing App
For 1.99 its fine. Doesnt have any features other than to create some clients and create some invoices within those clients. You can then either print them out or save them to PDF and do what you want with them. I would like to see the ability to email invoices right from the app and also be able to move "paid" invoices to another folder.
