Treat MYOB with extreme caution. It's expensive software for what it does and it should be ashamed to offer upgrades to its core program to the Mac community when it doesn't have a Mac version of its Retail Manager (windoze only). If you want to run a retail buisness through MYOB forget it! Or if you want to TRY and run any business through MYOB without Retail Manager and combine item and service sales, forget it!! (Duh ... I sell service and parts ... MYOB = sod off). Strangely, its interface is setup in part to incorporate Retail Manager but the lazy so-and-sos are waiting for the right level of whinging before it's written. At the end of the day it's only a fancy database for gods' sake. And just before you get excited about crumbs from the MYOB table, the windoze version of Retail Manager is close to $1000 for what I would consider basic functionality.
