Help Nigerian Restaurants Source Local Ingredients Reliably

Chefs at Nigerian restaurants often want to buy from local farmers — tomatoes from Jos, mushrooms from Ibadan, fresh herbs from their state — but find it impossible to do so reliably. Deliveries come late or not at all. Quality varies dramatically between orders. Payment terms that work for restaurants (net 30) do not work for farmers (payment on delivery). The result is that many restaurants default to sourcing imported equivalents despite preferring local. Your challenge is to design a B2B local ingredient sourcing platform that connects mid-market Nigerian restaurants and hotels (spending ₦500,000 to ₦5 million monthly on food) with local farmers and aggregators. It must guarantee delivery within a specified window, provide quality specifications that farmers can reliably meet, offer payment terms that work for both sides, and be manageable by a head chef via WhatsApp. Submit a service design document (max 10 pages) including: the supplier network model, quality specification and grading approach, delivery guarantee mechanism, payment terms bridge, how restaurants interact with the service, and a plan to serve 100 restaurants in Lagos or Abuja within 12 months. Judging criteria: 35% reliability design and delivery guarantee, 30% quality management system, 20% payment terms innovation, 15% scale plan.
