Payment fraud controls are vital for UK SMEs and growing businesses, especially during supplier onboarding, bank detail changes, and handling urgent payment requests. As fraudsters continually adapt their methods, finance teams must implement a payment fraud controls checklist that goes beyond policy documentation or basic staff training. The following guide outlines actionable, practical steps to strengthen your processes and reduce your exposure to financial loss and regulatory scrutiny.
Supplier Onboarding: Verifying Authenticity at the Outset
Weak onboarding procedures are a prime entry point for payment fraud. Implementing thorough verification protocols when adding new suppliers is essential for fraud prevention and regulatory compliance.
- Carry out identity and legitimacy checks using Companies House, VAT registration, and a direct phone call to a publicly listed number.
- Request original bank statements or a supplier letterhead showing bank details (never accept details solely via email attachments).
- Separate duties: ensure the person onboarding a new supplier is not the same individual who approves their first payment.
- Use an approved supplier list, reviewed quarterly, to prevent unauthorised additions.
- Document and retain all verification evidence for audit purposes.
For additional support with due diligence, consider engaging external specialists such as those at Company Junction, who can assist with company verification and background checks.
Technology Solutions for Supplier Onboarding
Consider using onboarding software that automates company checks, flags inconsistencies in supplier data, and securely stores onboarding evidence. Digital platforms can also integrate with government databases and manage approval workflows, improving both efficiency and control.
Bank Detail Changes: Multi-Factor Verification
Bank account change requests are a common vector for payment redirection fraud. A robust, multi-step process is essential for any effective payment fraud controls checklist:
- Always confirm bank changes by calling the supplier using a phone number from your original file, not the one provided in the change request.
- Require a signed change request on company letterhead, ideally with a second signatory for companies above a certain size.
- Check for recent changes in supplier contact details or personnel as these can indicate account compromise.
- Apply a mandatory waiting period (e.g., 48 hours) before processing bank changes to allow further validation if needed.
- Update your finance system audit log to record who made and approved each change.
Embedding Technology in Bank Change Controls
Modern finance systems can enforce dual authorisation, trigger alerts for high-risk changes, and maintain detailed logs of all modifications. Look for software that automates reminders for waiting periods and integrates with your supplier database to minimise manual error and fraud risk.
Integrating these steps with your finance software and ensuring system permissions align with your control framework is a key part of effective operational financial management.
Urgent Payment Requests: Preventing Social Engineering
Fraudsters exploit urgency and authority, often impersonating executives or suppliers to trigger rushed payments. Establishing non-negotiable procedures for urgent requests is critical for fraud prevention:
- No payment should be processed on the basis of email or text alone, regardless of apparent urgency or seniority.
- Require verbal confirmation with the requestor via a trusted phone number and secondary internal approval for all urgent payments.
- Set clear thresholds—such as any payment over £10,000—to trigger additional scrutiny and cross-checking.
- Train staff to recognise red flags: requests outside normal procedures, unusual language from known contacts, or last-minute bank changes.
- Document every urgent request and the steps taken to validate it for future reference and review.
Technology Solutions to Counter Social Engineering
Payment approval platforms can require two-factor authentication for high-value or urgent transactions and provide real-time alerts for suspicious patterns. AI-driven monitoring tools can analyse communication for phishing indicators or unusual payment requests, further strengthening your defences.
Reinforce a culture where finance team members feel empowered to challenge any request, even those that appear to come from the board or senior management.
Embedding Controls: Training, Technology, and Accountability
For a payment fraud controls checklist to be effective, controls must be embedded into everyday operations and supported by up-to-date technology, clear accountability, and a culture of vigilance. Key actions include:
- Regular staff training focused on real-world scenarios and the latest fraud tactics, including simulated phishing exercises.
- Implementing finance system user permissions to enforce segregation of duties and approval limits.
- Periodic spot-checks and internal audits of payment processes, with clear documentation trails.
- Ensuring a clear escalation process for suspicious activity, supported by a designated fraud response lead.
- Using a tax risk register framework to record, monitor, and review payment fraud risks as part of broader financial governance.
- Leveraging automation for routine checks and exception reporting, ensuring human oversight for all critical decisions.
Recommended Technology Integrations
Adopt secure payment platforms that support role-based access controls, workflow automation, and audit logging. Consider using supplier portals for document upload and verification, and workflow management software to streamline approvals and recordkeeping.
Technology can automate parts of the process but must be combined with human oversight and a robust compliance culture.
Regulatory and Legal Considerations
Failure to prevent payment fraud can expose your business to regulatory penalties and reputational damage. UK law requires directors to maintain adequate controls to protect company assets. For detailed, situation-specific advice, refer to our legal and compliance guidance resources.
For companies managing complex group structures or international suppliers, specialist corporate company secretarial services can help ensure your onboarding and payment processes are robust and fully compliant.
Conclusion
Payment fraud can be significantly reduced with the right controls at supplier onboarding, when handling bank detail changes, and in responding to urgent payment requests. By embedding this payment fraud controls checklist into your financial operations and regularly reviewing controls, your business can minimise losses, maintain regulatory compliance, and build lasting trust with suppliers and stakeholders.
