For accurately pricing quotes for new, small, and medium business customers, integration with third-party systems is necessary in scenarios where meter technical data is required from the Distributed System Operator (DSO) to confirm supply capability (B), and where credit ratings are used as a pricing input (D). Integrating with the DSO's systems ensures accurate supply feasibility assessments, while integrating with credit rating agencies provides the necessary financial risk insights to inform pricing decisions effectively. Reference = Salesforce Energy and Utilities Cloud documentation on pricing and quoting emphasizes the need for accurate data, which may require integration with external systems for meter data and credit assessments. Information on integrating Salesforce with external systems for enhanced quoting accuracy can be found in Salesforce's integration and API documentation: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/
