Comarch ERP Altum works fine in flat, one-subsidiary companies as well as in those with dispersed structure.
However, what definitely distinguishes Comarch ERP Altum from among other systems available on the market is the possibility of running many companies with one software. The multi-company approach is based on two assumptions: centralized management of all the companies operating under a holding company and the management of each of them separately.
Comarch ERP Altum platform is intended for international market, where, as in Poland, it is being implemented in enterprises of complex and multi-company structure. An example of such company is, among others, a well-known French company Chrétien. This enterprise manages several own, independent companies within one system - Comarch ERP Altum.
