Inventory Theft Schemes

Why Inventory Theft Schemes Matter
Inventory theft schemes are a core topic within the ACFE's Fraud Examination section, specifically under Asset Misappropriation: Inventory and Other Assets. The ACFE Report to the Nations consistently identifies non-cash misappropriation as a significant fraud category, and inventory is the most commonly stolen non-cash asset. For a Certified Fraud Examiner, understanding how inventory walks out the door, how employees conceal the shortage, and how examiners detect these schemes is essential. Exam questions on this topic test both conceptual understanding (what distinguishes one scheme from another) and practical judgment (which red flag or control applies to a given scenario).

What Is an Inventory Theft Scheme?
An inventory theft scheme is a form of asset misappropriation in which an employee (or an employee in collusion with an outsider) steals inventory or other non-cash physical assets belonging to the organization. The ACFE Fraud Tree classifies these under Non-Cash Misappropriations, which include both misuse (unauthorized use of assets without permanent removal) and larceny (the actual taking of assets). Inventory theft schemes fall into the larceny branch and are generally broken down into the following types:

1. Larceny Schemes – The simplest form. An employee takes inventory from the premises without attempting to conceal the theft in the books and records. Examples include a warehouse worker carrying goods out, a retail clerk taking merchandise, or an employee walking off with supplies. These are often opportunistic and depend on lax physical security.

2. Asset Requisitions and Transfers – The employee uses internal documents (requisition forms, transfer orders, work orders) to move inventory from one location to another or to a project, then steals it. For example, an employee requisitions more materials than a job requires and takes the excess, or fabricates a project entirely to justify the requisition.

3. Purchasing and Receiving Schemes – Fraud occurs at the point the inventory enters the company. A receiving clerk may falsify receiving reports to show fewer goods were received than actually arrived, then steal the difference. Alternatively, the employee may mark the shipment as short or damaged, or the company may pay for goods that were diverted directly to the employee. This category overlaps with billing schemes, so the exam often tests whether you can distinguish the two: if the company pays for goods it does not receive, that is a billing scheme; if the goods are received and then stolen, that is a non-cash scheme.

4. False Shipments and Fraudulent Sales – The employee creates false sales documents or shipping documents so that inventory is shipped to the employee or an accomplice. Because a sale is recorded, the removal of inventory appears legitimate. The resulting receivable is never collected and is often written off as bad debt, or the sale is recorded to a fictitious customer. Variations include fake sales (where no sale really occurs and the inventory is simply taken) and sales to accomplices at deeply discounted prices or with no intent to pay.

5. Other Schemes – These include scrap and waste manipulation (declaring good inventory as scrap and then taking it), collusion with vendors or delivery drivers, and theft of returned merchandise.

How Inventory Theft Schemes Work: Concealment
The fraud itself is usually straightforward; the difficulty for the perpetrator lies in concealment. Inventory theft leaves a gap between the perpetual inventory records (book inventory) and physical inventory counts. This gap is called inventory shrinkage. Perpetrators conceal shrinkage using several methods, which are heavily tested:

• Altered Inventory Records – Changing perpetual inventory counts to match the lower physical count, or adjusting receiving records to show fewer units received.
• Fictitious Sales and Accounts Receivable – Recording a sale so the inventory removal appears legitimate; the uncollectible receivable is later written off.
• Write-Offs to Scrap, Obsolescence, or Damage – Characterizing stolen goods as lost, obsolete, or destroyed.
• Physical Padding – Manipulating the physical count itself, such as stacking empty boxes, filling containers with worthless material, or moving the same inventory to be counted twice at different locations.
• Falsified Shipping Documents – Showing goods were shipped to legitimate customers when they were diverted.
• Forced Reconciliation – Simply plugging the inventory account to force book and physical counts to agree.

Concealment is often unnecessary in small, sporadic thefts, but it becomes essential as the scheme grows or when the organization performs regular counts. The ACFE emphasizes that the inability to conceal shrinkage is frequently how these schemes come to light.

Red Flags of Inventory Theft
• Unexplained or rising inventory shrinkage
• Significant increases in scrap, waste, or obsolescence write-offs
• Increases in bad debt write-offs, especially tied to specific salespersons or customers
• Discrepancies between receiving reports, purchase orders, and invoices
• Inventory adjustments made by employees who have access to physical inventory
• Shipments to unfamiliar addresses, P.O. boxes, or employee addresses
• Employees who refuse to take vacation or who insist on performing the inventory count alone
• Missing or altered requisition and transfer documents
• Sales recorded with no corresponding payment and no collection follow-up

Detection Methods
• Statistical sampling of inventory for physical verification
• Perpetual inventory reconciliation to physical counts, with investigation of all variances
• Analytical review, such as comparing shrinkage, scrap, and cost of goods sold ratios across periods, locations, or industry norms
• Trend analysis of inventory adjustments and write-offs by employee
• Document matching of purchase orders, receiving reports, invoices, and shipping documents (three-way or four-way match)
• Computer-assisted audit techniques to identify duplicate shipments, shipments to employee addresses, and unusual adjustment patterns
• Surveillance and physical security review of loading docks, exits, and storage areas

Prevention and Internal Controls
• Segregation of duties – Separate requisitioning, purchasing, receiving, custody, shipping, and recordkeeping. The person who has physical custody should never be able to adjust inventory records.
• Independent physical counts performed by individuals who do not have custodial responsibility, with surprise counts where feasible.
• Prenumbered and controlled documents for requisitions, receiving reports, and shipping documents.
• Receiving controls – Blind receiving (receiving clerk does not see the ordered quantity) to ensure independent counts.
• Physical safeguards – Locked storage, access logs, cameras, and restricted entry to high-value inventory.
• Approval requirements for all inventory adjustments, write-offs, and scrap disposals, reviewed by someone independent of the warehouse.
• Monitoring of bad debt write-offs and credit memos to detect fictitious sales.

How to Answer Exam Questions on Inventory Theft Schemes
CFE exam questions in this area tend to follow predictable patterns. You will typically be asked to (1) identify the type of scheme described in a scenario, (2) identify the concealment method being used, (3) select the most appropriate red flag or detection technique, or (4) choose the best internal control to prevent a specific scheme. Approach each question by asking yourself: At what point in the inventory cycle did the asset leave the company's control, and what document or record was manipulated? The answer to that question nearly always points to the correct scheme classification.

Exam Tips: Answering Questions on Inventory Theft Schemes

1. Know the Fraud Tree placement. Inventory theft is a Non-Cash Misappropriation under Asset Misappropriation. It is not a fraudulent disbursement and not a cash scheme. If a scenario involves cash leaving the company, you are likely in a different branch.

2. Distinguish misuse from larceny. Misuse is unauthorized borrowing or use (an employee using company equipment for a side business); larceny is permanent taking. The exam frequently tests this distinction.

3. Separate billing schemes from receiving schemes. If the company pays for goods it never receives, think billing scheme (fraudulent disbursement). If goods arrive and are then stolen or recorded as short, think purchasing and receiving inventory scheme.

4. Recognize false sales by the receivable. When a scenario mentions a sale with no payment received, a write-off to bad debt, or a shipment to an unusual address, the scheme is likely a fraudulent sale or false shipment.

5. Requisition language is a clue. Words such as transfer order, work order, project materials, or requisition point to an asset requisition and transfer scheme.

6. Shrinkage is the key concealment concept. Any question about hiding the difference between book inventory and physical inventory is about concealing shrinkage. Know all the methods: altered records, fictitious sales, write-offs, physical padding, and forced reconciliation.

7. For control questions, choose segregation of duties first. When asked for the most effective control, the answer is frequently separating custody of inventory from recordkeeping and from the ability to make adjustments. Independent physical counts are the next most common correct answer.

8. For detection questions, think analytical. Comparing shrinkage, scrap, and write-off trends over time or across locations is a classic correct answer. Statistical sampling of physical inventory is another.

9. Watch for the word "best" or "most likely." Several answer choices may be partially correct. Eliminate those that address a different scheme type or that are reactive when the question asks for prevention.

10. Remember the human element. Red flags such as refusing vacation, insisting on performing counts alone, or having sole access to both inventory and records are frequently the correct answer in behavioral red-flag questions.

By mastering the scheme categories, the concealment methods, the specific red flags, and the matching controls, you will be well prepared to handle any inventory theft question on the CFE exam.
