Pharmaceutical Inventory OS
Multi-Tier Unit Engine
Pro-Rata Fraud Shield v2.8
Advanced pharmaceutical stock control powered by a dynamic Multi-Tier Unit Conversion Engine (Box → Strip → Tablet) with high-speed POS scanning, pro-rata refund calculations, and immutable traceability.

SYSTEM MODULES
Strict unit-conversion mathematical rules, continuous scanner autofocus, and unalterable ledger verification.
Auto-generates Code-128 and EAN-13 barcodes upon item creation. Tracks Reorder Threshold Alerts (Alert Amber) and quarantines expiring batches (Danger Crimson).
Hardware barcode scanner autofocus keeps cashiers typing-free. Dynamic dispensing dropdown recalculates remaining stock with hard validation against total stock.
Eliminates return fraud. Returns require original invoice lookup and recalculate pro-rata discount shares down to the base tablet unit: (refund = price * units - discount share).
Every movement generates an unalterable append-only ledger record logging pharmacist attribution, batch ID, workstation terminal, and post-transaction balance.
ARCHITECTURE DEEP DIVE
A dual-phase pharmaceutical engine solving fractional packaging conversion and fraudulent retail returns.

Eliminates stock count mismatches when pharmacies open master cartons to sell individual strips or loose tablets. The inventory ledger operates strictly on base units with real-time conversion wrappers.
Granular 3-Tier Packaging: Master Box → Blister Strip → Base Tablet
Dynamic dispensing dropdown automatically recalculates total available units
Hard validation shield prevents selling beyond verified base inventory
Auto-generated Code-128 and EAN-13 barcodes with batch assignment
Stops return shrinkage. Customers cannot claim full retail value on partial returns from discounted purchases. Returns require original invoice validation and recalculate pro-rata discount shares down to the tablet.
Pro-Rata Formula: refund = (unit_base_price * qty) - discount_share
Mandatory original invoice lookup gates all return authorization requests

PROJECT TIMELINE
A phased trajectory taking multi-tier pharmaceutical conversion from architectural specification to multi-store rollout.
Month 1–2
Design of base-unit decrement schemas, mathematical modeling for fractional packs, and database foreign keys.
Month 3
Hardware integration with 1D/2D laser scanners via WebHID, continuous field refocusing, and sub-0.2s lookup speeds.
Month 4
Real-time packaging format switcher (Box, Strip, Tablet) with immediate recalculation and negative-stock prevention.
Month 5
Implementation of pro-rata refund calculations, original invoice lookup requirements, and automatic unit restock hooks.
Month 6–7
Danger Crimson automated expiry quarantine locks and SHA-256 cryptographic sealing for all inventory movements.
Month 8
Rollout across 15 high-volume retail dispensaries, cashier load-testing at 200+ transactions/hour, and regulatory sign-off.
INSTANT POS SANDBOX
PHARMA TERMINAL v2.8 ACTIVE
Scan simulated medicines, test the 3-tier unit dropdown (Box/Strip/Tablet), and try a pro-rata return against seeded invoices.
