I run a home business and would like to know what the best software there is for the mac that can create invoices, and keep a business contacts and all that stuff. there is this iphone app that does everything i need but i dont have an iphone. i forgot what it does. but you can keep seprate client information, and create invoices on the fly and the app also emails the client a digital invoice. i would like to know if this exists for mac? it has too right? i've looked for awhile and found nothing like this..
