Ordering + Invoicing Platform

Multi-tenant ops platform with orders, cash shifts, delivery zones, payment methods, and invoice sequencing.

Note: Presented as an ops platform. No game-specific branding/assets should be used publicly.

The Challenge

Order management was scattered across spreadsheets and chat messages.

No consistent invoicing, no delivery zone logic, no audit trail.

Constraints

  • Multi-tenant from day one -- multiple businesses on a single deployment
  • Real-time updates needed for live order status
  • Invoice sequencing must be legally compliant (no gaps)

Technical Decisions

  • Prisma + PostgreSQL for type-safe multi-tenant data access with row-level scoping
  • Socket.IO for real-time tenant-scoped events without polling overhead
  • Strict state machine for orders -- clear transitions prevent invalid states

Highlights

  • Multi-tenant core with RBAC permissions model
  • Order timeline + real-time tenant-scoped events
  • Invoicing entity with sequencing and status handling
  • Delivery zone management with geographic boundaries
  • Cash shift open/close with reconciliation

Results

  • Built as a foundation for reducing manual order ops and reconciliation
  • Designed for reliability: clear state transitions and audit-friendly data
