Unified Payment Gateway for Guinea

A digital wallet and checkout platform simplifying payments across all local payment sources.

Problem Statement

Digital payments in Guinea are fragmented. Consumers constantly switch between mobile money apps (Orange Money, MTN MoMo), bank apps, and cash-based workarounds. Merchants, meanwhile, are forced to support multiple providers, manage manual reconciliation, and still miss sales from unsupported sources.

This leads to:

  • Low digital commerce adoption due to checkout friction.
  • Technical and compliance burdens for each integration.
  • Poor customer and merchant experience.
  • Delayed product development for fintech and commerce platforms.

Objective

Create a startup-driven, PayPal-style payment platform tailored for Guinea that allows:

  • Users to pay online using just their phone number or email—regardless of whether the money comes from a bank account, mobile wallet, or internal balance.
  • Merchants to accept all major local payment methods through one clean integration.
  • Developers to plug into a unified system instead of rebuilding wallet, KYC, and payment logic from scratch.

Key Benefits

For Citizens

  • Pay easily with one account across all supported platforms and services.
  • Secure and familiar checkout on websites, mobile apps, or in-store.
  • Link multiple funding sources (wallets, banks, prepaid balances).
  • Fewer steps, less confusion—better digital experience overall.

For Merchants & Businesses

  • One dashboard to accept payments from all local financial channels.
  • Faster checkout leads to higher conversion rates.
  • Simplified settlement: payouts directly to wallet or bank of choice.
  • Less time spent on reconciling fragmented payment sources.

For Developers & Product Teams

  • One API to integrate Orange Money, MTN MoMo, banks, and more.
  • Prebuilt SDKs, documentation, and test environments.
  • Simplifies launch of ecommerce platforms, SaaS tools, and POS apps.
  • Faster development cycles, less overhead, and future-proof infrastructure.

Core Features

For Customers

  • Single Payment Identity: One phone or email to initiate all payments.
  • Wallet + Source Linking: Add funds or pay from mobile money, bank accounts, or saved cards.
  • Secure Checkout: OTP, PIN, and device-based trust for safety.
  • Unified Payment History: See all purchases and fund flows in one place.

For Merchants

  • One Integration: Unified API or plug-in for all payment types.
  • Real-Time Insights: Monitor sales, refunds, and transaction status.
  • Flexible Withdrawals: Cash out to bank or wallet on demand.
  • Ecommerce & POS Ready: Built to support both web stores and physical checkout.

Technical Overview

  • Architecture: Centralized payment orchestration with provider abstraction layer
  • Approach: Single API endpoint that routes to appropriate payment providers
  • Key Integrations: Orange Money, MTN MoMo, local banks, card networks

Implementation Approach

  1. Phase 1 - Research & Design: Analyze APIs and compliance docs from Orange, MTN, and local banks. Map out user flows, merchant flows, and risk requirements (KYC, AML).

  2. Phase 2 - MVP Build: Implement wallet engine, identity service, and sandboxed test payments. Provide a basic merchant dashboard and first-party checkout plugin.

  3. Phase 3 - Live Pilot: Partner with one telco and one bank to activate real payments. Onboard 10–20 early merchants in retail and ecommerce.

  4. Phase 4 - Open Launch: Scale integrations with more financial providers. Release developer portal, public documentation, and marketing campaigns.

Challenges & Mitigations

ChallengeMitigation
Unstable APIs or outagesAdd retry logic, caching, and graceful fallback layers
Regulatory complexity (KYC, AML)Integrate with third-party verification services, maintain audit trails
Liquidity and cash-out timingUse pooled accounts, float partnerships, and payout scheduling
Fraud & abuse (SIM swap, fake users)Implement layered authentication, velocity checks, device fingerprinting

Success Metrics

  • Total transaction volume processed through the gateway
  • Number of active merchants using the platform
  • Payment success rate across different providers
  • Average checkout completion time

Future Opportunities

  • In-store QR code–based payments for shops and markets.
  • Peer-to-peer (P2P) transfers and payment links.
  • Merchant lending and credit scoring based on payment history.
  • Remittance integration (from Europe/U.S. to Guinea) through the same wallet.
  • Open APIs for other startups building fintech apps on top of this ecosystem.
