Roundtable Advantage Accounting System is the most powerful software for the money for a small to medium sized business. We are the only UNIX certified national dealer for Advantage. Older versions of Advantage such as Premier and Armor are also supported. Please, contact us to determine your accounting needs.

Armor Systems went out of business in 1999. The Armor Premier and Excalibur programs are no longer produced by any manufacturer but Roundtable Software purchased the source code for Advantage in 1999 and continues to produce the Advantage Accounting System that was started by Armor Systems. Excelsior will support you in any way we can to help you continue running the older programs.
