Waste of Money
Youre better off paying $40+ for a real invoicing program on the App Store. There are options to change the headings for the invoice fields but you cant change their data type, you cant mark the date when an invoice was paid, you have to double-click a field EVERY. TIME. to change the value (tabbing through almost never works). Using Numbers to create invoices works better than this program.
