AUTOMATION
Automated Price Monitoring
Multi-marketplace price tracker monitoring 10K+ SKUs across Amazon, Walmart, and Target. Automated alerts for price drops, stock changes, and new competitor listings.
The challenge.
A consumer electronics brand selling across Amazon, Walmart, and Target needed to enforce MAP (Minimum Advertised Price) policies and respond to competitor pricing within hours, not days. They had no visibility into real-time pricing across 10K SKUs and were losing margin to unauthorized sellers undercutting their pricing.
The approach.
Multi-Marketplace Scrapers
Built dedicated scrapers for Amazon (product pages + buy box data), Walmart (API + web fallback), and Target (Redsky API). Each scraper handles marketplace-specific anti-bot measures independently.
SKU Matching & Normalization
Developed a UPC/EAN-based matching system to link the same product across marketplaces despite different titles, images, and seller names. Handles product variations (color, size, bundles) as linked but distinct SKUs.
Price Intelligence Engine
Tracks current price, historical price (30/60/90 day), buy box winner, seller count, stock status, and review count for every SKU. Calculates competitive position score and MAP violation flags in real-time.
Webhook Alerts & Dashboard
Sends instant webhook notifications to Slack and email when MAP violations, significant price drops (>5%), or stock-outs are detected. Provides a real-time dashboard with filterable views by marketplace, category, and alert severity.
