Dynamics 365 Sales is Microsoft’s cloud CRM for sales-oriented companies. With AI-powered insights, native Teams integration, and LinkedIn Sales Navigator, it transforms leads into opportunities and opportunities into revenue. Dun & Bradstreet, in turn, delivers validated business data on over 500 million companies worldwide, including compliance checks, risk assessment, and corporate structure.
The Dynamics 365 Sales Dun & Bradstreet Integration ensures that your accounts, contacts, and leads are automatically enriched with current D&B data. In real-time. Bidirectionally. Without manual maintenance. This keeps your CRM clean, compliant, and your sales teams working with reliable data.
Anyone working in B2B sales knows the problem: customer data ages quickly. CEOs change, companies merge, addresses are updated. The integration keeps your data current and opens up completely new possibilities.
Lead qualification in seconds. As soon as a new lead is entered in Dynamics, D&B immediately delivers industry, revenue, employee count, and risk score. Your sales team sees at a glance whether the effort is worthwhile. No more time wasted on dead leads.
Compliance automatically fulfilled. KYC, AML, ESG: Everything required by regulation is delivered by D&B directly into the CRM. You see Ultimate Beneficial Owner, sanctions status, and ESG scores in the account without having to research manually. Your compliance team can breathe easy.
New customer search with criteria. With D&B Criteria Search, you identify potential customers by industry, size, radius, or revenue and transfer them directly as leads into the CRM. Targeted campaigns instead of flying blind.
Risk monitoring for existing customers. D&B continuously monitors your accounts. Changes in creditworthiness, management, or legal structure are automatically pushed into the CRM. Your sales team reacts proactively before problems arise.
Avoid duplicates. The DUNS number is globally unique. When creating new accounts, the system automatically recognizes whether the company already exists. No more duplicate records.
Sales intelligence from the source. D&B delivers not just master data, but also corporate structure, franchises, subsidiaries, and ownership relationships. Your account management sees the complete picture and can pursue cross-selling in a targeted manner.
The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

APIs and real-time synchronization. Dynamics 365 Sales uses the Web API (OData v4), D&B provides data via the REST-based Direct+ API. MARINI orchestrates synchronization in real-time and bidirectionally. Change tracking on both sides ensures that only modified records are transferred.
Flexible mappings for all D&B Data Blocks. You define which D&B fields flow into which Dynamics fields: Master Data, Compliance, Financial Risk Assessment, or Company Financials. Custom fields in Dynamics are supported just like standard objects (Accounts, Contacts, Leads).
Monitoring and alerts without additional infrastructure. As soon as an account is linked with the DUNS, it is automatically added to D&B monitoring. Changes are pushed via webhook. You don’t need polling logic or batch jobs.
Security and compliance at eye level. MARINI hosts EU-only, the data center is ISO 27001 certified. OAuth 2.0 for Dynamics (Azure AD), API keys for D&B. All data flows are encrypted. Logs and audit trails are available at all times.
