# B2B - Account data model

Reference the tables and relationships that store business-to-business \(B2B\) customer accounts, contacts, account hierarchies, account relationships, and account teams.

## Overview of account data model

The B2B account data model captures the structures used when the customer is another business. It defines the account and contact entities that represent the customer organization and its individuals. It also defines the relationships, addresses, and team memberships that describe how the customer is served. The model extends platform foundations sys\_user, core\_company, cmn\_location, and CSM tables. Industry solutions build on it for B2B scenarios, such as insurance carriers modeling brokers, financial services modeling institutional clients, and healthcare payers modeling provider organizations.

In the B2B account data model diagram, the accounts and contacts \(with partner variants\) are mapped to a user. These are connected to account relationship, contact relationship, account team member, and account address. The responsibility and responsibility access configuration entities govern these access. Each entity refers to a shared reference and transaction data.
