B2B Export Marketplace - Africa

The Challenge

African producers make goods that buyers abroad want, but trust, paperwork and payments keep most of them out of export markets.

• Buyers can't verify suppliers. An importer in Europe, the Gulf or among the diaspora has no easy way to check that a producer is real, licensed and able to deliver.
• Origin is hard to prove. Under the African Continental Free Trade Area (AfCFTA), goods only qualify for lower or zero tariffs if they meet rules of origin, which means proving where and how much value was added.
• Payments carry risk on both sides. Buyers fear paying for goods that never arrive; producers fear shipping goods that are never paid for.
• Too many currencies. Trade across dozens of countries means naira, cedis, shillings and rand on one side, and dollars, euros or pounds on the other.
• Raw goods earn less. Producers who export unprocessed goods miss the premium that value-added products command.

The startup wanted one platform where verified African producers meet serious global buyers, with origin certified and payments protected.

Architecture

The platform is built around one rule: a producer is verified and certified before any buyer's money moves.

1. Supplier verification

   Producers register their company and products, then pass verification checks on documents and licences before they can list. Live in the MVP.

   

2. Value Addition Certification (VAC)

   A product chain verification workflow records how raw materials are transformed. Products that meet the 40%+ transformation threshold are certified, supporting AfCFTA rules-of-origin claims and premium pricing. Live in the MVP.

   

3. Verified listings

   Buyers, from diaspora shoppers to global importers, browse only verified producers and certified products.

4. Escrow-secured orders

   The buyer funds the order through Flutterwave, Paystack or Stripe, depending on where they pay from. Funds are held in escrow while the goods are produced and shipped (escrow is in development).

   

5. Supply-chain tracking

   Each shipment's progress and documents are tracked on the platform (in development).

6. Release and payout

   When the buyer confirms delivery as agreed, escrow is released and the producer is paid in their local currency.

Under the hood, the platform runs on Node.js services and a Next.js web app. MongoDB holds flexible records such as supplier profiles, product catalogues and certification documents, while PostgreSQL holds the transactional side: orders, escrow and payments. Product photos and trade documents are stored on AWS S3 and served through a CDN. A multi-region deployment keeps the platform fast for buyers in Europe, the Middle East and Asia as well as sellers in Africa, and lets data stay in-region where rules require it.

Trade-offs We Made

What we deliberately are not doing: launching as an open listing site and adding verification later. Once buyers meet one fake supplier, a marketplace rarely wins their trust back.

Where This Pattern Applies

The same verify, certify and escrow design fits any cross-border B2B marketplace where buyers can't meet sellers in person:

• Agricultural and processed-food exports, from cocoa and cashew to shea and coffee.
• Textiles, leather and crafts sold to importers and retailers abroad.
• Diaspora commerce, where buyers in Europe, the Gulf or North America order from home markets.
• Regional trade blocs beyond Africa, such as ASEAN or the Gulf, wherever origin rules decide the tariff.
