About This Course

AP invoice or billing fraud is among the most common and expensive types of occupational fraud worldwide. According to the Association of Certified Fraud Examiners (ACFE), organizations lose approximately 5% of their revenue to fraud annually, with billing schemes accounting for roughly 22% of these cases globally.

AP fraud schemes typically last a long time—often 18 months before detection—and over half of them cause losses exceeding $100,000.

This comprehensive course equips finance professionals with essential skills to detect, prevent, and combat accounts payable and vendor manipulation fraud. You'll master the critical aspects of AP fraud prevention through practical, real-world scenarios that blend theoretical knowledge with actionable strategies.

Through this focused training program, you'll learn to:

  • Identify common AP fraud schemes: Discover the various deceptive methods fraudsters use to exploit accounts payable systems, including fictitious invoices, shell vendors, and payment diversions.

  • Recognize red flags and warning signs: Learn to spot subtle indicators that may signal fraudulent invoice or vendor activity.

  • Implement effective preventive controls: Explore key strategies to establish robust safeguards that prevent AP fraud before it occurs.

  • Deploy detective controls: Gain insights into monitoring techniques that help identify suspicious activities early.

  • Leverage technology solutions: Understand how to use RPA (Robotic Process Automation) and AI (Artificial Intelligence) to enhance your fraud prevention capabilities.

The course provides downloadable AP fraud and vendor manipulation red-flag cards that serve as quick reference guides for identifying the most common fraud indicators.

Whether you're an AP or procurement specialist, accounting manager, controller, auditor, or finance professional, this course will sharpen your "fraud lens" and equip you with practical tools to protect your organization from costly AP fraud schemes and vendor manipulation.

star312 reviews

My courses focus on practical applications of AI in accounting and finance, alongside fraud prevention, e-invoicing and financial reporting ethics. – AI Finance: Build and customise reconciliation tools and fraud dashboards using plain-language prompts (“vibe coding”), without prior programming experience. Learn to validate results, protect sensitive data and create repeatable workflows. – Fraud prevention and internal controls: Recognise red flags in invoices, payments, payroll and other transactions, and apply preventive controls and structured investigation methods. – E-invoicing: Understand global requirements, electronic invoice formats and opportunities to automate accounts payable and receivable. – Financial reporting ethics: Work through accounting judgments, estimates and ethical dilemmas using practical cases and decision-making tools. My teaching draws on 30 years of experience in accounting, finance leadership, internal and external audit, and transformation, including roles at Big4 firms, DELL, SSE and TOMRA. I am a Fellow of ACCA (FCCA) and the founder of E-LITE Consulting and RSAgile.
