₦1.5m ‘Overpayment’ Scare Raises Fresh Concerns Over Retail Fraud Tactics

A Nigerian businessman’s account of a suspicious transaction at his clothing shop has triggered renewed attention to a growing pattern of payment-related scams targeting small retailers, particularly those who rely on instant bank transfers.

The trader, who shared his experience on social media, described how what began as a routine ₦15,000 purchase escalated into a ₦1.5 million transfer—an anomaly he says nearly exposed him to a potential money laundering scheme.

While the claim has not been independently verified, the sequence he described aligns with known fraud tactics that exploit trust, urgency and confusion in digital payments.

A Transaction That Didn’t Add Up

According to the businessman, the customer selected items and requested his account details to make payment. During the process, her behaviour appeared unusual: repeated phone calls, stepping outside the shop, and apparent attempts to confirm whether funds had been sent.

Moments later, he received an alert—₦1.5 million instead of ₦15,000.

“When I checked, it was ₦1.5 million. I immediately knew something was wrong,” he said in his post.

The woman reportedly attributed the discrepancy to a network error and suggested an alternative arrangement: she would purchase more goods and then retrieve the remaining balance.

When pressed on how she intended to collect the excess funds, she allegedly provided a different bank account—raising further suspicion.

A Known Scam Pattern

Financial crime experts say the tactic described resembles a common scheme designed to “clean” illicit funds by routing them through unsuspecting third parties.

In such cases, a fraudster transfers a large sum—often from a compromised or stolen account—to a legitimate business. They then attempt to convince the recipient to refund the excess to a different account, effectively obscuring the money trail.

By insisting on refunding the money only to the original sending account, the businessman disrupted what could have been a laundering attempt.

“I told her I would only send the money back to the same account that transferred it,” he said.

He eventually received matching account details and refunded the full ₦1.5 million, after which he asked the customer to leave without completing any purchase.

What Is Confirmed—and What Isn’t

There is no official confirmation from law enforcement regarding this specific incident, and the identities of those involved remain unknown. It is also unclear whether the funds originated from a legitimate or compromised source.

However, the scenario reflects broader concerns raised by banks and regulators about increasingly sophisticated fraud schemes in Nigeria’s fast-growing digital payments ecosystem.

The Bigger Context: Digital Payments and Rising Risk

Nigeria has seen rapid adoption of cashless transactions in recent years, driven by mobile banking, fintech platforms and policy shifts encouraging electronic payments. For small business owners, instant transfers have become the norm.

But this convenience has come with new vulnerabilities.

The Central Bank of Nigeria (CBN) and commercial banks have repeatedly warned customers and merchants to verify unusual transactions, particularly overpayments and requests to redirect refunds. Fraudsters often rely on speed—pressuring victims to act before they can fully assess a situation.

Retailers, many of whom operate without formal financial safeguards, are especially exposed. A single misstep—such as refunding money to the wrong account—can result in financial loss or even police scrutiny if the funds are later traced to criminal activity.

Why This Matters for Ordinary Nigerians

For everyday traders, the implications are immediate. Accepting transfers is now standard practice in markets and shops across the country, but many lack the training to identify red flags.

The businessman’s decision to pause, question the transaction, and insist on a traceable refund route likely prevented a more serious outcome.

His concluding warning reflects a growing awareness among small business owners:

“No matter what you want to buy, send the exact amount—no more, no less.”

What Comes Next

Incidents like this rarely progress to formal investigation unless a complaint is filed, but they contribute to a larger pattern that financial institutions are struggling to contain.

Experts advise traders to adopt basic safeguards: confirm transaction details, avoid third-party refund requests, and report suspicious activity promptly to banks or security agencies.

As Nigeria deepens its shift toward a cashless economy, the burden of vigilance increasingly falls on individuals. For many small businesses, the difference between a successful sale and a costly mistake may come down to a moment of caution.
