When your business has multiple branches, you will need to share business data like payments and receipts, stock details from branches/warehouses, and so on. This data sharing can be between different branches, or between the head office and branches/warehouses. You can use data synchronization to share and update data between two or more locations, including head office and branches/warehouses. At both locations, you must have the same release of Tally Prime. However, you need not maintain continuous internet connectivity to do synchronization.
