Achieving Sub-Second Omnichannel Inventory Synchronization

The Double-Booking & Out-of-Stock Problem

Retail chains operating both physical flagship outlets and high-traffic e-commerce storefronts frequently face the double-booking nightmare: a customer purchases the last pair of shoes online at 2:01 PM, while a physical shopper buys that same pair at the store register at 2:02 PM.

Legacy batch reconciliations that run every midnight cannot prevent this. The result: canceled customer orders, negative reviews, and wasted support hours.

The Event-Driven Inventory Ledger

Nabik Core ERP solves this through sub-second event-driven inventory routing: * Every barcode scan at a point-of-sale register broadcasts an inventory deduction event via WebSocket / Redis PubSub in under 200 milliseconds. * Connected e-commerce marketplaces and webstores receive immediate stock decrement signals, ensuring web visitors never see phantom inventory. * Offline resilience allows stores to continue transacting during internet drops, queuing encrypted transaction logs for automatic dual-ledger reconciliation upon reconnection.
