INES is designed for small and medium-sized businesses. Thanks to its variable characteristics, it can also be used in budgetary and contributory organizations. It is a complex economic system, which is one of the few that solves the management of economic agendas in both double-entry and simple accounting systems. It covers retail sales specifications, it is also aimed at wholesalers (due to the sophisticated ordering system and many possibilities in pricing policy), manufacturing companies (possibility of product calculations, infinite breakdown for raw materials), but also for accounting firms (export and import of data from processed companies), auditors and tax advisors, for whom and with their cooperation the complete system is developed and maintained. INES is written in the Czech programming language PC FAND by ALIS s.r.o. It is a DOS application that runs in a windows environment.
