Detty December in Nigeria has evolved beyond a holiday season into a major economic cycle. From Lagos to Abuja, the final weeks of the year unleash a surge in consumer spending across nightlife, hospitality, fashion, e-commerce, travel, and live events. Concert tickets sell out within minutes, restaurants operate late into the night, online merchants record peak order volumes, and fintech infrastructure processes transactions at extraordinary scale. Beneath this celebratory boom, however, a quieter challenge is gaining momentum: fraudulent reversals.
At its foundation, a chargeback is designed as a consumer protection tool. When a cardholder reports an unauthorised transaction or a failure to deliver goods or services, banks reverse the payment while an investigation is carried out. In theory, the mechanism preserves trust within the payments ecosystem. In practice, particularly during high-volume periods such as Detty December, the system is increasingly exploited. Fraudulent chargebacks—often referred to as friendly fraud, occur when customers dispute legitimate transactions after receiving the product or service.
Detty December creates an environment where this abuse can flourish. Transaction volumes rise sharply, stretching merchant operations, customer service teams, delivery networks and reconciliation processes. When pressure mounts, oversights become more common: missed confirmations, delayed fulfilment, incomplete records. Fraud typically takes hold where processes are weakest.
Urgency compounds the risk. The season is dominated by last-minute purchases, including same-day deliveries, rush bookings, pop-up events, and flash sales. Many informal or newly onboarded vendors relax verification standards to maximise conversion and speed. While this approach may boost short-term sales, it often exposes merchants to disputes weeks later.
Cross-border spending further complicates matters. Diaspora visitors arrive with foreign-issued cards, higher spending limits and unfamiliar authentication requirements. Merchants keen to avoid declined payments may waive additional checks, only to face disputes after customers have left the country and transaction scrutiny intensifies.
Merchants are already encountering familiar scenarios. Event organisers report cases where customers attend concerts, share footage online, then later file disputes claiming services were not rendered or alleging card-not-present fraud. Without robust attendance records—such as QR scans or timestamped entry logs—banks may rule in favour of the cardholder, leaving organisers to absorb both the lost revenue and chargeback fees.
In retail and e-commerce, same-day delivery presents its own risks. Social media vendors frequently process urgent orders for fashion items or electronics, relying on informal delivery confirmations. Where proof of delivery is limited to verbal assurance, merchants struggle to defend disputes alleging non-delivery.
Payment descriptor confusion is another recurring issue. During periods of intense spending, customers reviewing January bank statements may not recognise aggregator or processor names. Rather than contacting the merchant for clarification, some cardholders dispute the transaction outright, triggering reversals that merchants must contest.
For hospitality businesses, particularly those serving international guests, cross-border disputes can be especially costly. Charges for dining, nightlife or hotel add-ons may later be challenged once customers return overseas. These cases often involve longer resolution timelines and stricter evidence requirements, which many merchants are ill-prepared to meet.
The financial impact extends well beyond individual transactions. Elevated dispute ratios can result in rolling reserves, delayed settlements, increased processing fees or even account suspension. For small and medium-sized businesses, the resulting cash-flow strain can be severe. At a systemic level, widespread chargeback abuse pushes banks and fintechs to impose tighter controls, increasing friction for legitimate customers and compliant merchants alike.
More resilient businesses are responding by treating chargeback prevention as an essential part of festive planning. They prioritise transaction clarity through detailed receipts, instant payment confirmations via SMS or WhatsApp, and clearly identifiable merchant names. Delivery processes are reinforced with one-time passwords, timestamped photographs and basic digital logs linked to order references.
Event organisers are strengthening attendance verification through QR-based entry systems, wristbands tied to customer details and securely stored check-in records. Restaurants and nightlife venues are retaining booking confirmations and table allocations connected directly to payment references.
Clear communication has also emerged as a critical defense. Transparent refund and cancellation policies displayed at checkout reduce impulse disputes, while responsive customer support channels help resolve confusion before it escalates into a bank complaint. Merchants are also paying closer attention to behavioural patterns, flagging repeat disputers, unusually high-value rush orders, and inconsistent customer information.
Detty December remains a powerful driver of Nigeria’s consumer economy. It fuels employment, accelerates innovation and projects the country’s creative industries onto the global stage. Yet as transaction volumes continue to grow, operational discipline must keep pace. Fraudulent chargebacks represent a hidden tax on festive growth - incremental, often unnoticed, but deeply damaging over time.
For merchants, the lesson is straightforward. Celebration, and scale must be balanced with structure and accountability. Those who invest in stronger processes will not only weather Detty December more effectively, but will also retain more of the value it generates long after the festivities have ended.
