West Africa
Real network, wallet, and multi-store constraints — not a lab demo.
Problem
Retailers ran on notebooks, spreadsheets, and improvised tills — cash errors, blind stock, forgotten credits, and end-of-day totals rebuilt by hand.
Solution
POS, real-time inventory, Wave & Orange Money at the till, multi-store ops, and accountant-ready exports for local reconciliation.
Constraints
- Reliable counter ops on unstable networks.
- Strict multi-tenant isolation by merchant and store.
- Traceability for sales, credit, and mobile money.
- Exports owners and accountants can close the books with.

Architecture
React SPA for POS and dashboards; Spring Boot multi-tenant REST API; async jobs for reports, bulk imports, and accounting exports; store-scoped inventory and role-based staff access.
Decisions
- 01
Multi-tenant model
One platform, isolated ops, roles, and inventory per merchant.
- 02
Async jobs
Exports, imports, and reports off the checkout path so the till stays fast.
Trade-offs
Robustness over analytics in v1 — reliable checkout, tenant isolation, and reconciliable exports beat pitch-deck dashboards under network and wallet pressure.
