weclapp is a cloud ERP for small and medium-sized businesses that unifies inventory management, CRM, order management, and accounting. Dun & Bradstreet (D&B) delivers validated business data, compliance information, and risk assessments for over 400 million companies worldwide.
The weclapp Dun & Bradstreet integration enriches your customer data in real-time with D&B information: Validated addresses, credit data, UBO checks, and ESG scores flow automatically into your ERP. This enables you to make informed credit decisions, meet compliance requirements, and keep your customer base up to date.
The connection between weclapp and Dun & Bradstreet automates data quality and risk management across all business areas.
Validate and enrich customer data. New customers in weclapp are matched against D&B data: Address, legal form, management, and DUNS number are automatically supplemented. You save manual research and reduce errors.
Credit check before order release. Before an order is released in weclapp, MARINI retrieves the current credit rating from D&B. Orders with negative scores are flagged for manual review. Your receivables risk decreases.
Compliance data for KYC and AML. Ultimate Beneficial Owner (UBO) and sanctions screening are automatically pulled from D&B and stored in weclapp as custom attributes. Your compliance department has all data in one place.
Monitoring for existing customers. Once a customer in weclapp is linked with a DUNS, MARINI activates D&B monitoring. You’re automatically notified of changes such as insolvency, rebranding, or address changes. Proactive risk management becomes routine.
Qualify suppliers with D&B data. Your suppliers in weclapp are also enriched with financial risk assessments and ESG scores. You identify supplier risks early and meet sustainability requirements.
New customer search via criteria search. With D&B criteria search, you identify potential new customers by industry, size, and region. Matches are transferred directly as leads into weclapp. Your sales team starts with clean, validated data.
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.

For: marketing, sales, customer success, operations
End manual data maintenance. Before: You google company names, compare addresses in business registers, and laboriously enter everything into weclapp. After: MARINI retrieves data from D&B, and the customer is fully set up in seconds. You gain time for consulting instead of administration.
Current overview of customer creditworthiness. Before: You don’t know if a customer is solvent and release orders at risk. After: The credit score appears directly next to the order in weclapp. For critical cases, you see a signal and can react before it’s too late.
Proactive receivables management. Before: You learn about insolvencies from newspapers or when invoices bounce. After: D&B monitoring automatically informs you of negative developments. You approach customers early, arrange prepayment, or reduce credit lines.
New customer acquisition with validated data. Before: Leads from campaigns are incomplete, and you waste time on companies that no longer exist. After: Criteria search delivers qualified company lists that flow directly into your CRM. Your first contact is based on facts, not speculation.
For: IT, development, system architects, admins
No installation, no custom development. MARINI connects weclapp and D&B via the REST APIs of both systems. You install nothing in weclapp, write no code, and need no middleware to maintain. The integration runs in the MARINI cloud, EU hosting included.
All D&B data blocks available. From master data to compliance to financial risk assessment: You decide which data blocks to retrieve. Mapping to weclapp fields (standard or custom attributes) is configured via drag-and-drop. Changes go live in minutes.
Bidirectional and event-driven. Webhooks in weclapp trigger MARINI when a new customer is created. MARINI retrieves D&B data, maps it, and writes it back. You control whether data flows immediately or in batches. Rate limits and retry logic are built in.
Monitoring and automatic alerts. Once a customer is linked with DUNS, MARINI activates D&B monitoring. Changes are pushed, not polled. In the MARINI dashboard, you see which customers received updates and can define workflows for critical events (e.g., credit deterioration).
Business-critical data deserves maximum reliability. At MARINI, security isn’t an add-on—it’s our lived standard. Our security architecture at a glance:
This keeps your central data infrastructure stable, protected, and scalable at all times. Together, we’ll find the right integration and tailor it precisely to your requirements.
All D&B data blocks are available via MARINI: Master Data (Basic and Extended), Sales & Marketing Intelligence, Compliance (Basic and Extended), Financial Risk Assessment (Traffic Light to Comprehensive), and Company Financials. You decide which data blocks to retrieve for which customers. An overview is available on the MARINI Data Marketplace.
Yes. When a new customer is created in weclapp, a webhook can trigger MARINI. MARINI retrieves D&B data in real-time, maps it, and writes it back. Alternatively, you can configure batch runs, for example nightly for all new customers. Both modes run stably and respect rate limits.
Once a customer in weclapp is linked with the DUNS, you can activate D&B monitoring. Updates in the D&B Data Cloud are automatically pushed. MARINI writes the changed data back to weclapp and can notify you via alert, for example for negative credit changes or address changes.
Yes. In weclapp, suppliers are treated the same as customers. MARINI retrieves D&B data for both object types. For suppliers, financial risk assessments and ESG scores are particularly relevant for evaluating supply risks and sustainability requirements.
With D&B criteria search, you can identify potential new customers by criteria such as industry, size, address, and radius. MARINI delivers matches as a list that you can import directly as leads or customers into weclapp. This way you start with clean, validated data instead of incomplete tables from unknown sources.
D&B compliance data blocks include Ultimate Beneficial Owner (UBO), sanctions screening, PEP lists, and ESG scores. You can store this data as custom attributes in weclapp or display it in a separate compliance dashboard. For audits and regulatory requirements, you have all evidence centralized in your ERP.


With MARINI, we use a reliable interface between our existing ERP system and HubSpot. The data exchange works seamlessly and delivers tangible added value in our day-to-day operations. We are particularly impressed by the platform’s clear structure as well as the direct and straightforward communication with the support team.
