Omnichannel Inventory & POS Operating System for Retail Resellers

Replaced fragmented spreadsheets and manual WhatsApp ordering with a full-stack, real-time inventory and POS system featuring automated tag-intake and tiered staff commission tracking.

The Challenge

High-velocity sneaker and apparel resellers frequently struggle with operational drag when juggling in-store foot traffic, Shopify e-commerce, and manual sales across Instagram DMs and WhatsApp.

Managing high-ticket inventory through fragmented spreadsheets led to three recurring operational failures:

Inventory Lag & Double-Selling: Pairs sold in-store remained active online, triggering accidental backorders and customer cancellations.

Slow Product Intake: Staff manually typed out SKU codes, sizing details, and price benchmarks for dozens of incoming pairs daily.

Manual Commission Auditing: Calculating individual staff commissions across split-channel sales consumed hours of tedious spreadsheet reconciliation each pay cycle.

The Solution & Architecture

I engineered a unified, mobile-first web application designed around the physical rhythm of store operations. Built to act as both an in-store POS and a centralized backend hub, the system synchronizes stock instantly across all physical and digital channels while automating daily bookkeeping.

Core Features & System Modules

AI-Assisted "Snap & List" Intake:

Staff can capture a photo of a sneaker's box or size tag directly from a smartphone. Optical recognition identifies the style code, model, and size, automatically pulls historical pricing benchmarks, and generates a ready-to-print barcode label in seconds.

Pair-Level Inventory Tracking:

Every physical item is tracked as an individual serialized unit—storing specific cost basis, consignment agreements, condition photos, and shelf aging (days in stock).

Instant Multi-Channel Sync:

The moment an item is rung up in-store or reserved via customer direct message, it is instantly marked out-of-stock across all integrated digital channels to prevent overselling.

Customer Hold & Deposit Engine:

Dedicated hold management with automated countdowns, deposit tracking, and single-click checkout conversions once the balance is settled.

Automated Commission Calculations:

Built-in tiered sales attribution brackets ($3k, $6k, $12k+ tiers) that calculate real-time staff earnings, base salaries, and net profit margins without manual accounting.

Dual Interface (Light / Dark Mode):

Fully responsive interface optimized for desktop back-office administration and fast mobile floor usage, complete with end-of-day register cash balancing.
