The Head quarter - standard used for the chain locations helps in getting store wise reports in terms of their purchase, sales, inventory and outstanding. The server at the store level communicates with the server at the head office through an EDI tool called NetTrade . The stores can carry out the billing even in offline mode. Once when the internet connection regains the data transfer from the outlet to the HO happens systematically through Net trade right from the period when internet connection was off. In HQ standard, master data is not managed centrally which means consolidation of inventory and accounts is not available in standard edition.
