Sizes and Colors is an Administrative Software and Point of Sale made with high tech for retail stores of any size. Our project started in 1995 with the suppoty of the Entrepeneurship program of Tecnológico de Monterrey and with pilot testing in our own stores. After 5 years of redesign and depuration, we started selling our software in the whole country. Being a part of the retail industry has helped us to identify what are the real needs of shoe makers in Mexico becuase in the end we speak the same language: FOOTWEAR.
