© 2011 Southside Computers MagicPos is a development of Southside Computers. It has been designed from the ground up to enforce a system of control over any retail food business.  It is the system more than the computers that a store owner buys. MagicSUB is the Subway specific version of MagicPOS.  It has all the features of MagicPOS as well as complying with Subway’s paperwork and reporting requirements. Southside Computers will undertake the writing of custom software for clients.  We use a variety of languages and databases to achieve the results our customers require.
