Why Your Procurement Process Needs Fraud Prevention

Common Procurement Fraud Scenarios

For a detailed walkthrough of the approval chain itself, see our multi-level approval guide. This post focuses on why those controls matter from a fraud prevention perspective.

Procurement fraud is more common than most organizations realize. The Association of Certified Fraud Examiners (ACFE) reports that the median loss from procurement fraud schemes is // ===================================================================== // END OF NEW BLOG POSTS // ===================================================================== ];50,000 per incident, and that organizations lose an estimated 5% of annual revenue to occupational fraud. Common scenarios include:

• Ghost vendors — fictitious suppliers created by an employee who approves invoices to themselves
• Inflated pricing — an employee colludes with a supplier to inflate prices and splits the excess
• Unnecessary purchases — ordering materials the organization does not need for personal use or resale
• Duplicate payments — submitting the same invoice twice and pocketing the second payment

Every one of these scenarios requires a single person to have too much control over the purchasing process.

Separation of Duties — The Foundation

The fundamental defense against procurement fraud is separation of duties: the person who requests a purchase should not be the person who approves it, receives the goods, or authorizes payment. When these responsibilities are distributed across multiple roles, fraud requires collusion — which is significantly harder and riskier than solo schemes.

How Controlled Approval Chains Work

No Single Point of Failure

TacTech.ai's multi-level approval chain enforces separation by requiring three independent approvals: Purchase Manager, Project Manager, and Accountant. No single person can create a purchase request, approve it, and receive the goods. Each role sees the request independently, bringing their own perspective and checks.

Audit Trails for Every Transaction

Every request, approval, rejection, purchase order, and receiving voucher creates a timestamped, attributed record. These audit trails serve as both a deterrent (people behave differently when they know they are being watched) and a forensic tool (if fraud occurs, the trail shows exactly where controls failed).

Supplier Comparison Reports

Price inflation fraud becomes visible when you can compare what you pay a supplier against market rates or alternative suppliers. Supplier comparison reports surface pricing anomalies — if you are paying Supplier A 40% more than Supplier B for the same item, the question is whether there is a valid business reason or whether someone is profiting from the difference.

Connect procurement data with HR management to cross-reference purchasing authority with employee roles and responsibilities.

Building a Fraud-Resistant Procurement Culture

1. Enforce approval chains for every purchase — no exceptions, no workarounds, no "I'll get it approved later"
2. Rotate purchasing responsibilities — no single person owns a supplier relationship indefinitely
3. Review audit trails regularly — not just when something goes wrong, but as a routine monthly check
4. Benchmark pricing quarterly — compare what you pay against market rates
5. Communicate the policy — employees who know controls exist are less likely to attempt fraud

How do approval chains prevent procurement fraud? By distributing purchasing authority across multiple independent roles, no single person can create, approve, and receive a purchase. Fraud requires collusion between multiple people, which is significantly harder to execute and conceal.

What is separation of duties in procurement? Separation of duties is an internal control principle where the person who requests a purchase is different from the person who approves it, who is different from the person who receives the goods and authorizes payment.
