Why B2B Digitization Failed in Nigeria's Informal Markets: The misread behind a $40b market.

Between 2019 and 2022, a wave of venture-backed platforms entered Nigeria's informal retail market with a shared conviction: that digitizing supply chain interactions and centralizing demand would unlock one of Africa's largest underserved economies. The opportunity was real. Nigeria's food and consumer goods retail market exceeds $40 billion, with over 90% of transactions occurring through informal channels.

What failed was not the market. It was the model.

Platforms misread the structure of informal commerce. They assumed fragmentation signaled inefficiency and that retailer aggregation would translate into control. In reality, fragmentation was a deliberate strategy. Retailers multi-source to manage price volatility, stock uncertainty, and credit access simultaneously.

As a result, platforms did not capture demand. They participated in it. Retailers onboarded, but did not consolidate spend. Adoption increased, but loyalty did not.

To compete, platforms defaulted to price. In a market where gross margins already sit between 3% and 6%, this led to sustained margin compression, rising operational costs, and dependence on subsidies. Over $164 million in capital was deployed into infrastructure designed to capture non-exclusive demand in a system where control does not sit at the transaction layer.

This paper argues that informal B2B commerce is not constrained by lack of coordination, but structured around continuous risk management. Any model that assumes customer ownership, demand exclusivity, or margin expansion through aggregation alone will fail. The path forward lies not in digitizing transactions, but in embedding within the system's core functions: inventory certainty, credit access, and logistics reliability.
