Extend Microsoft Dynamics 365 Customer Insights for account-oriented B2B engagement. This add-on supplies B2B Accounts capability under an annual subscription term, allowing organizations to work with account contexts in Customer Insights rather than limiting planning to individual contacts. It fits deployments where business accounts are a meaningful part of the customer relationship. Customer Insights B2B scenarios commonly require an account relationship alongside the people associated with that organization. This add-on addresses that account-oriented requirement within the Customer Insights environment. Apply it where marketing or customer-engagement teams need account-level context for B2B audiences, relationships, and engagement activities. It is software licensing rather than an appliance, cable, or peripheral. Part number 42AA3628F72B-1Y identifies the one-year B2B Accounts add-on, separating it from Customer Insights subscriptions aimed at other functional scopes or terms. Its defining characteristics are the Customer Insights association, B2B Accounts designation, and annual duration. Ensure that the Customer Insights tenant and licensing configuration support the required B2B Accounts scope before assignment.
