AMCCIT provides a unified XML specification empowering POS vendors to fully integrate their POS programs with all of the functions of the Zen Global Portal retail management system. In some cases local vendor POS programs are more appropriate to the retail environment in a country. This may because of language or business practices in the country. Some systems are implemented in more than one country and it is easier and a better Return On Investment (ROI) for the customer to make use of either existing POS software or to use a local POS software vendor for support or other reasons. AMCCIT facilitates such needs.
