Map business system companies to Avalara companies

Provide a company management interface that:

Retrieves and displays companies from the Avalara tenant
Retrieves companies from the user’s business system or ERP
Allows users to select a company from their system and map it to an existing Avalara company

Store these mappings in a persistent and secure data structure within the connector. This makes sure that mappings remain available across sessions and system updates.

This approach supports multientity environments and enables dynamic resolution of company-to-mandate relationships.
