SAP Business One allows you to manage multiple entities with various strategies including: cost accounting using cost centres and dimensions; branch enabled functionality enabling you to manage multiple entities within one SAP Business One database in one localization (country); using separate SAP Business One databases for each entity within the same or different localizations.
The SAP Business One intercompany integration solution allows you to manage intercompany transactions for multiple companies by automatically replicating corresponding transactions across multiple company databases or branches within one database.
