Inventory shrinkage is not merely a bookkeeping error. It is a direct leak of working capital that erodes profit margins and stalls growth.
For a small business, the difference between recorded stock and physical inventory represents cash that has vanished from the balance sheet.
Whether caused by employee theft, shoplifting, or administrative errors, shrinkage reduces the amount of cash available to reinvest in stock or expand operations.
Identifying the sources of loss
Shrinkage typically stems from four areas: internal theft, external theft, supplier fraud, and administrative mistakes.
Internal theft is often the most damaging because employees know where the blind spots are. A common example is a retail staff member under-ringing a sale to pocket the difference.
Administrative errors often look like theft. This happens when items are received from a supplier but not entered into the system, or when stock is damaged but not written off.
Supplier fraud occurs when a business pays for 100 units but only receives 90. Without a strict receiving process, this loss is often missed until a full audit.
Operational controls to secure stock
The most effective way to reduce theft is to remove the opportunity. Segregation of duties is the first line of defence.
The person who orders the stock should not be the same person who receives it or performs the inventory count.
When one person controls the entire chain, the risk of undetected theft increases significantly.
Implement a strict receiving protocol. Every delivery must be physically counted against the packing slip and the original purchase order before the driver leaves.
Store high-value items in locked cabinets or restricted areas. For a pharmacy in Lagos or a boutique in Nairobi, keeping expensive items behind a counter reduces the risk of shoplifting.
The role of documentation and technology
Relying on memory or manual notebooks leads to shrinkage. A basic Point of Sale (POS) system provides a digital trail for every item sold.
Regular cycle counts are more effective than one massive annual audit. Count a small section of inventory every week.
This allows owners to spot discrepancies quickly. If a specific product line shows consistent shrinkage, the owner can investigate that specific shift or process immediately.
CCTV should be positioned at entry and exit points and near the point of sale. The presence of cameras serves as a psychological deterrent for both staff and customers.
Poor record-keeping often leads to compliance issues during tax audits, as missing stock may be incorrectly flagged as undeclared sales.
SME owners should start by performing a full physical stock count this weekend to establish an accurate baseline for their records.
