Project Overview

Overview: The platform provides a shared digital payments core that can support independently configured programmes for SACCOs, co-operatives, merchants, enterprises, and other institutions. A multi-tenant Wallet-as-a-Service model provides tenant-level branding, rules, roles, reporting, and data isolation while operating on a common platform core.

Access Channels: The solution delivers role-based services through a React Native mobile application, React.js / Next.js web portal, and USSD services for customers, merchants, agents, businesses, institutions, and administrators.

Financial Operations: The core platform combines double-entry wallet accounting, transaction processing, payment and settlement workflows, automated daily reconciliation, tiered eKYC, AML/CFT and fraud monitoring, audit logging, and configurable business rules.

A Multi-Tenant Core for Digital Financial Services

The platform brings wallet operations, payments, settlement, compliance, reconciliation, and institution-specific configuration together in one governed architecture, while allowing each tenant to operate with its own branding, rules, roles, fees, reporting, and member data.

The Challenge

  • Support multiple financial-service programmes on a shared platform without exposing data or operational configuration across tenants.
  • Provide consistent financial accounting through a double-entry ledger that supports customer, merchant, business, agent, institution/trust, and escrow wallet types.
  • Serve different user groups through appropriate channels, including mobile applications, web portals, and USSD for users without internet access.
  • Connect the platform with banks, national payment infrastructure, mobile money operators, billers, KYC/AML providers, notification services, and regulatory reporting systems.
  • Build security, eKYC, AML/CFT monitoring, reconciliation, auditability, and configurable business controls into the core operating model.

Our Solution

  • Core Wallet & Ledger Engine - a centralised wallet and transaction engine using double-entry accounting, atomic postings, idempotency controls, transaction-state tracking, reversals through compensating entries, and auditable financial records.
  • Multi-Tenant WaaS - tenant isolation with independent branding, member wallets, business rules, fee schedules, transaction limits, roles, administrators, reporting, and trust/escrow account positions.
  • Role-Based Channels - mobile, web, and USSD experiences tailored to customers, merchants, businesses, agents, institutions, and platform administrators, including wallet funding, transfers, QR payments, bill payments, airtime, cash-in/cash-out, and bulk disbursements.
  • Payments, Settlement & Reconciliation - integrations for national payment rails, banks, mobile money, billers, and other partners, supported by configurable settlement rules and automated daily matching across ledger, external rails, and trust/escrow records.
  • Security & Compliance - OAuth 2.0 / JWT, RBAC, MFA, encryption, tiered eKYC, sanctions and PEP screening, AML/CFT monitoring, fraud and risk controls, immutable audit logging, and regulatory reporting outputs.
  • Cloud & Operations - containerised deployment supporting cloud, on-premise, or hybrid models, with PostgreSQL, MongoDB, Redis, Kubernetes-ready architecture, monitoring, logging, backup, and disaster-recovery capabilities.
  • Regulatory Alignment - the architecture is mapped to Zambia's National Payment Systems Act, BoZ electronic-money directives, the Data Protection Act, FIC AML/CFT obligations, and ZRA Smart Invoice requirements, with final regulatory interpretation and licensing handled by the client/partner.
  • Reporting & Monitoring - operational, financial, settlement, user, merchant, agent, and regulatory reporting supported by platform dashboards, audit logs, exception tracking, and Prometheus/Grafana/ELK monitoring.
