Supplier database check: Validation of bank data in supplier management
November 19, 2025
Supplier database verification is an essential part of modern procurement, which involves validating and verifying the bank details of potential and existing suppliers. This systematic verification ensures secure payment processing and minimizes fraud risks in the supply chain. Find out below what supplier database verification means, which methods are used and how you can implement them successfully.
Key Facts
- Systematic validation of IBAN, BIC and account holder data to prevent fraud
- Reduces payment defaults and incorrect transfers by up to 95
- Legal compliance requirements under the AMLA and the EU Money Laundering Directive
- Automated testing procedures significantly shorten onboarding times
- Integration into existing ERP and procurement systems possible

Definition: Supplier database check
The supplier database check refers to the systematic validation and verification of bank details of new and existing suppliers as part of the procurement process.
Core elements of bank data validation
The check includes several critical components to ensure correct payment processing. The central validation points are
- IBAN format check and check digit validation
- BIC code verification and bank identification
- Account holder comparison with supplier master data
- Sanctions list screening and compliance checks
Supplier database data check vs. standard credit check
In contrast to supplier credit checks, bank data validation focuses exclusively on the technical and legal correctness of payment details. While credit checks assess the ability to pay, bank data validation ensures the secure transfer of funds.
Importance in modern Procurement
Bank data verification is an integral part of supplier onboarding and makes a significant contribution to minimizing risk. It supports compliance requirements and optimizes the efficiency of payment processes throughout the supply chain.
Methods and procedures for supplier database checks
Modern companies rely on structured validation procedures that combine technical tests with regulatory requirements.
Automated validation procedures
Technical verification mechanisms form the foundation of efficient bank data validation. These include algorithmic IBAN validation, BIC database reconciliation and real-time account checks via banking APIs. Supplier portals integrate these functions seamlessly into the registration process.
Compliance-oriented test steps
Regulatory validation is carried out through systematic screening against sanctions lists, PEP databases and watch lists. Risk Management defines specific screening criteria based on country risks and transaction volumes.
Documentation and tracking
Complete audit trails document all test steps and validation results. This documentation supports internal controls and external audits, while at the same time creating the basis for continuous process optimization.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Important KPIs and targets
Measurable key figures enable the continuous optimization of bank data verification processes and their effectiveness.
Validation quality and accuracy
The error detection rate measures the proportion of correctly identified incorrect bank data. Target values are over 99% for automated checks. False positive rates should remain below 2% to ensure operational efficiency. These metrics provide sustainable support for supplier evaluation.
Process efficiency key figures
The average validation time per supplier and the degree of automation of the inspection processes are key efficiency indicators. Modern systems achieve validation times of less than 24 hours with 95% automation.
Compliance and key risk figures
Sanction hit rates and compliance violations are measured monthly. The number of fraud cases prevented and losses saved quantify the ROI of bank data validation and justify investments in advanced validation systems.
Risk factors and controls for supplier database checks
Inadequate bank data validation can lead to significant financial losses and compliance violations.
Fraud risks and manipulation
Falsified or manipulated bank details pose the greatest risk. Cyber criminals use social engineering and phishing attacks to divert payments. Robust validation procedures and multi-factor authentication effectively minimize these supplier risks.
Regulatory compliance risks
Violations of money laundering laws and sanction regulations can lead to substantial fines. Continuous updating of sanctions lists and regular quality audits ensure compliant processes.
Operational default risks
System failures or incomplete data validation can cause payment delays. Redundant testing systems and backup procedures ensure the continuity of critical procurement processes and minimize operational disruptions.

Practical example
A medium-sized mechanical engineering company implements automated bank data validation for international suppliers. The system validates IBAN formats, checks BIC codes against current bank directories and compares account holder data with supplier master data. It also screens against EU sanctions lists and PEP databases. Within six months, the error rate for payments is reduced by 87%, while the onboarding time for new suppliers drops from five to two days.
- Automated IBAN validation with real-time feedback
- Integration into existing ERP systems
- Continuous monitoring of existing supplier data
Trends & developments around supplier database checks
Digitalization and stricter regulation are driving innovative developments in bank data validation.
AI-supported fraud detection
Artificial intelligence is revolutionizing the detection of suspicious bank data changes and fraud attempts. Machine learning algorithms analyze patterns in supplier data and identify anomalies in real time. These technologies significantly reduce false positive rates and improve the precision of risk analysis.
Open Banking Integration
PSD2-compliant APIs enable direct access to bank data for real-time validation. This integration accelerates verification processes and significantly increases data quality in supplier management.
Blockchain-based verification
Distributed ledger technologies create immutable audit trails for bank data validation. This development strengthens trust between business partners and simplifies regulatory verification for cross-border transactions.
Conclusion
Supplier database validation is an indispensable component of modern procurement strategies and ensures secure, efficient payment processing. Automated validation processes significantly reduce fraud risks and support regulatory compliance requirements. Companies that invest in robust verification systems benefit from reduced operational risks and optimized supplier relationships. Continuous development through AI and open banking integration will further increase the importance of these processes.
FAQ
What does a complete supplier database check involve?
A comprehensive check validates IBAN format and check digits, verifies BIC codes, compares account holders with supplier data and carries out sanctions list screening. Country risks are also assessed and compliance requirements checked.
How often should supplier database data be checked?
New suppliers are fully validated before the first payment is made. Existing suppliers should be re-validated when data changes and at least annually. High-risk suppliers require quarterly reviews to minimize risk.
What are the legal requirements for bank data checks?
The German Money Laundering Act (GwG) and EU sanctions regulations define minimum standards for supplier checks. Companies must fulfill appropriate due diligence obligations and report suspicious transactions. Documentation obligations extend over five years.
How can bank data checks be integrated into existing systems?
Modern validation solutions offer APIs for seamless ERP integration. Standard interfaces enable real-time checks during supplier registration. Batch processing supports the validation of large amounts of data during system migrations.
