Platform Infrastructure
Architecture built for operational truth.
MagnusOP is engineered with non-negotiable architectural invariants designed to keep commerce registers fast, inventory traceable, and financial records indisputable.
Append-Only Inventory Ledger
Stock movements are historical truth. Stock quantity is strictly derived.
- Every sale, customer return, supplier receipt, and damaged item appends an immutable movement row.
- Derived stock balances eliminate mysterious inventory drift and shrinkage.
- Cryptographic provenance ensures auditability down to the cashier, location, and timestamp.
Offline-First POS Resilience
Registers keep processing sales when internet connectivity drops.
- Catalogues, barcodes, and local pricing are indexed directly within browser storage.
- Cashiers continue barcode scanning, splitting tenders, and printing receipts uninterrupted.
- Queued transactions synchronize idempotently the moment network connection restores.
PostgreSQL Row-Level Security
Bank-grade database tenant isolation enforced at the engine layer.
- Every tenant-scoped table enforces business_id foreign keys and RLS policies.
- Tenant identity is derived server-side from cryptographically signed session tokens.
- Cross-tenant data leakage is mathematically impossible at the database level.
Deterministic Integer Minor Units
Zero floating-point drift across double-entry financial statements.
- All monetary amounts are stored as integer minor units (kobo/cents).
- The server independently calculates all order subtotals, tax rates, and discounts.
- Every transaction creates balanced debits and credits in the central general ledger.
Allowlisted Automation & Merchant AI
Automated operational intelligence with human-in-the-loop safeguards.
- AI can run analytical read-only queries freely across sales and stock records.
- Mutating actions run only through merchant-configured, allowlisted automation rules.
- Any action touching monetary transactions strictly mandates one-tap human approval.
Public Projection DTO Boundary
Strict separation between internal ledger state and public web storefronts.
- Online storefronts read strictly from curated public projections.
- Wholesale supplier costs, margin ledgers, and cashier notes are never exposed.
- Public store checkouts synchronize instantly with in-store physical shelves.
