Sage announced that in 2012 the company are changing the names of many of the core accounting and ERP lines. These products will be identified with a numbering approach where higher numbers denote increasing levels of product capability or sophistication.
Sage Accpac ERP is now released with the new Sage branding and is now Sage 300 ERP 2012.
In addition the editions naming is changing. It would be confusing to have Sage 300 ERP 200 Edition 2012. So 100, 200 and 500 editions become Standard, Advanced and Premium Editions. Hence something like Sage 300 Advanced ERP 2012.
