Your cash register is leaking without you knowing. These 5 leaks are the most common
💰 1. Poorly reconciled M-Pesa transactions
You receive M-Pesa payments, but you don't record them all. A typo, a missed SMS, a customer saying "I sent you the money" without you checking. Result: 7–15% of your M-Pesa revenue goes unrecorded, according to an analysis of 1,367 Kenyan businesses . A silent leak that accumulates month after month.
Concrete example: In a survey of 1,367 Kenyan traders, over 40% of those using manual methods had reconciliation errors averaging 7% of their monthly turnover .
The remedy: Digitise your reconciliation. A system that automatically matches M-Pesa payments to sales eliminates these errors . Don't let your staff record M-Pesa transactions by hand anymore.
🔄 2. Unauthorised voids and discounts
An employee voids a sale after the customer pays. The money disappears. Or they give a friend a discount and pocket the difference. These "voids" and "discounts" are among the hardest leaks to detect.
Concrete example: A KEPSA study found that Kenyan businesses lose nearly 13% of revenue to internal fraud: cash skimming, fake invoices, supplier collusion, and book falsification .
The remedy: Every void or discount must be manager-approved. A POS system with access controls prevents employees from modifying transactions without authorisation .
📦 3. Employee stock theft
35% of small retailers in Nairobi lose between KES 100,000 and 500,000 per year to internal stock theft . Employees steal products, create fake "returns", or simply don't ring them up at the till.
Concrete example: A Kasarani hardware store discovered its supervisor was approving "returns" that never happened. KES 67,000 per quarter was disappearing . An Eastleigh supermarket was losing KES 200,000 per month to unrecorded transactions, fake returns, and goods leaving without being logged .
The remedy: A POS system with real-time stock tracking and differentiated access levels. Over 70% of retail theft comes from inside . Once the system is in place, monthly losses can drop from KES 200,000 to under KES 15,000 .
🏦 4. Bank fees and hidden charges
Account maintenance fees, ATM withdrawal fees, transfer fees, overdraft fees, SMS alerts at KES 3–7 each. These small charges add up. For active accounts, SMS fees alone can exceed KES 200 per month . An SME making 50 transactions a month can lose thousands of shillings in fees.
Concrete example: Kenyan banks charge out-of-network ATM fees up to KES 250 per transaction, and loan processing fees of 1–3% of the loan amount .
The remedy: Review your bank statement regularly. Identify all recurring charges. Negotiate with your bank to reduce fees. And cancel services you don't use.
👥 5. Non-eTIMS compliant supplier payments
You pay suppliers, but their invoices aren't in eTIMS. In 2026, KRA validates every line of your return by cross-checking with your eTIMS invoices . Any expense not backed by a valid electronic invoice is automatically disallowed. You pay twice: once for the goods, once for the taxes.
Concrete example: KRA now imposes penalties for any non-compliant eTIMS expenses .
The remedy: Demand an eTIMS invoice for every business purchase, even from informal suppliers.
Tip: Internal controls are your first line of defence. External audits validate your accounts once a year. Internal controls protect your money every day .
Do it now: Take your bank statement from last month. Identify 3 charges you don't understand. For each, call your bank or supplier and ask for an explanation. 30 minutes today, thousands of shillings saved tomorrow.
