StockLogic
An operations platform that runs a real multi-channel commerce business — 2,500+ SKUs kept in sync across eBay, Walmart, and WooCommerce, with barcode workflows, AI demand forecasting, and AI bundle mapping in one command center.
Running one catalog across eBay, Walmart, and WooCommerce means every stock change, order, and listing has to stay consistent across three systems that each have their own API, auth model, and data quirks. At 2,500+ SKUs — many of them bundles assembled from other products — doing this by hand leads to overselling, dead listings, and stock counts that drift the moment anything moves. The genuinely hard parts aren't the CRUD screens. They're keeping OAuth tokens alive per marketplace, decrementing component stock when a bundle sells, reconciling a separate listing state for each SKU on each channel, catching sync failures before they cause an oversell, and surfacing which of thousands of items actually need attention right now.
StockLogic is a single command center for the whole operation. Marketplace sync: serverless API routes handle each marketplace's OAuth and push/pull inventory, orders, and listings for eBay, Walmart, and WooCommerce. A sync-audit view tracks link status, stale checks, and per-channel errors so nothing silently falls out of sync. Bundles + Visual Mapper: inventory supports both simple products and kits — selling a kit automatically decrements its component SKUs. A 'Visual Mapper' uses an AI vision model to look at a photo of a set and detect which SKUs it contains, turning a manual bill-of-materials into an automated one. Warehouse + catalog: a UPC master plus barcode/QR generation and printable labels drive warehouse work, and CSV/Excel import-export moves catalog data in and out in bulk. AI forecasting: an engine computes sales velocity per SKU from real order history and projects days-remaining, run-out dates, and suggested reorder dates, flagging 'restock now' items automatically. Sales intelligence: a sales & profit module tracks COGS, marketplace commission/processing fees, and net margin per order, alongside customer and shipping-state analytics. Built with React + TypeScript (Vite), Supabase for the Postgres database, auth, and cloud backup, serverless functions for the marketplace integrations, html5-qrcode for scanning, and an AI vision model for bundle detection.
A mature system in daily use on a real catalog of 2,500+ products — tracking live marketplace links (1,850+ Walmart, 2,240+ WooCommerce, plus eBay), thousands of automated audit checks, and real sales, profit, and customer data. It went well past an MVP into genuine daily-operations software.
