From the developer:
Invoice is a full-featured invoice application for SOHO or business users. It has been designed from scratch to use the power and beauty of the Mac OS, while making life as easy as possible for its users. Since Invoice was designed purely for OS X, it is not simply a port from another platform, unable to take full advantage of the OS X operating system. Invoice uses it all.
