What is Shopify Inventory Tracking?
Shopify inventory tracking is the practice of monitoring the stock levels of products on any Shopify store over time. By taking regular snapshots of a store's inventory, you can detect when products sell (stock decreases) and when they are restocked (stock increases).
ShopXray takes this further with variant-level accuracy. Rather than just tracking products, we monitor individual variants — every size, color, and option. On paid plans, our proprietary technology reveals exact unit counts, so you know that a competitor has 47 units of "Blue / Large" remaining — not just that it's "in stock."
How ShopXray Tracks Inventory
Basic Availability Detection
Available on all plans. ShopXray monitors whether each product variant is available or unavailable. This gives you a clear in-stock versus out-of-stock view across the entire catalog.
Advanced Quantity Detection
Available on paid plans. Our proprietary technology detects exact stock quantities for each variant, returning precise unit counts. This is the most accurate way to monitor competitor inventory without admin access.
Variant-Level Monitoring
Every variant is tracked independently. A product with 5 sizes and 3 colors has 15 variants — ShopXray tracks all 15. This granularity reveals which specific options are popular and which are sitting unsold.

Why Track Competitor Inventory?
Inventory data reveals what no other metric can — real demand. A product that frequently restocks is in genuine demand. A product that stays fully stocked for weeks may not be selling. Low stock on a specific variant tells you exactly which options are popular. This intelligence directly informs your product sourcing, pricing, and marketing decisions.
