The starting point
A retail company needed an enterprise POS and ERP to handle many simultaneous sales, with SUNAT tax integration and DNI/RUC lookup at checkout.
The decision
Clean Architecture and Domain-Driven Design, with .NET microservices communicating over gRPC and per-environment deployment on Kubernetes.
What we did
- Enterprise POS platform with payment gateways
- DNI/RUC lookup inside the checkout
- Admin panel for multiple stores
- Real-time reports
Results
- 21 developers coordinated in a single repository
- SUNAT tax integration inside the sales flow
