Tension Software has announced Invoices 2.9 (http://www.pomola.com/products_invoices/invoices.html), an update native Cocoa application to create and manage invoices on Mac. The new version sports layout changes to increase ease of use, internal improvements and a document migrator inside the application itself (it’s not a separate app anymore).
Invoices requires Mac OS X 10.5 or higher. It’s Universal Binary so runs natively on both Power PC and Intel systems.
Invoices costs US$40; version 2.9 is a free update for registered users of version 2.x. A demo is available for download.
