A method for processing disputes in a multi-tenant architecture system includes receiving, at a first service provider, a dispute request from a second service provider that manages entity identities of a plurality of customers. The dispute request indicates a disputed transaction between a customer of the plurality of customers and another entity. The method includes accessing an identity manager to determine a customer representation, the identity manager previously onboarded the plurality of customers as a plurality of customer representations. The identity manager is hosted by the first service provider that manages customer representations corresponding to entity identities of the customers. The dispute request is propagated with the customer representation to a dispute management engine that determines an outcome for the dispute, the determination based on characteristics of the disputed transaction and on characteristics of the customer. The method also includes propagating the determination to the second service provider.
