Inventory & Stock Monitoring

Accuracy varies by platform. On sites that display exact quantities (e.g., 'Only 3 left in stock'), we capture the precise number. On sites that only show availability status (in-stock / out-of-stock), we detect and record those binary signals. Our AI also infers approximate stock velocity from add-to-cart patterns and listing behavior changes.

On our real-time monitoring plan, out-of-stock events are detected and alerts are delivered within 2 minutes. This is critical because competitor stockouts are time-sensitive opportunities — the sooner you know, the sooner you can adjust your pricing or ramp up ad spend to capture the displaced demand.

Yes. Many clients connect their own inventory management systems (e.g., NetSuite, Cin7, Linnworks) via our API to get a combined view of their stock versus competitor stock. This side-by-side comparison is particularly valuable for identifying when you have exclusive availability in a category.

We monitor all major marketplaces including Amazon (FBA and FBM), Walmart, eBay, Target, Best Buy, Wayfair, Shopee, Lazada, and any direct-to-consumer website. For Amazon specifically, we track Buy Box ownership, third-party seller inventory, and FBA versus merchant-fulfilled stock separately.

Our AI analyzes multiple signals to classify stockout events. A temporary stockout typically shows the listing remaining active with 'temporarily out of stock' messaging. A discontinuation shows the listing being removed, redirected, or marked as unavailable without a restock date. Historical restocking patterns also inform the classification with high accuracy.

Yes. Our demand prediction models analyze sales velocity signals, current stock level indicators, historical stockout patterns, and seasonal demand curves to forecast stockout risk. When a product is trending toward a stockout, you receive an early warning alert before the actual event, giving you time to act proactively.

The bullwhip effect is a supply chain phenomenon where small fluctuations in consumer demand get amplified as they travel upstream through the supply chain, causing increasingly volatile inventory levels at each stage. Real-time inventory monitoring helps dampen this effect by providing accurate, current demand signals rather than relying on delayed order data. This allows businesses to make purchasing decisions based on actual consumption patterns rather than distorted signals.

Safety stock is the extra inventory held as a buffer against unexpected demand spikes or supply delays. It is typically calculated using historical demand variability, supplier lead time variability, and your desired service level. Holding too much safety stock ties up capital and increases warehousing costs, while holding too little leads to stockouts and lost sales. Competitor inventory monitoring adds another dimension by letting you increase safety stock when competitors are depleting theirs.

FBA (Fulfilled by Amazon) inventory is stored in Amazon's warehouses and is generally more visible through stock indicators and Prime eligibility badges. FBM (Fulfilled by Merchant) inventory is stored by the seller and typically shows less granular stock information publicly. For competitive monitoring, FBA listings often display more precise stock level signals, while FBM listings may only show basic in-stock or out-of-stock status, requiring different monitoring approaches for each fulfillment type.

Sell-through rate measures the percentage of inventory sold within a specific time period relative to the amount received. A sell-through rate of 80% in 30 days means 80% of the stock received was sold within a month. This metric is critical because it indicates demand health and inventory efficiency. Low sell-through suggests overstock or weak demand, while very high sell-through may indicate you are under-ordering and losing potential sales.

Dead stock refers to inventory that has not sold within a defined period and is unlikely to sell at regular price, while overstock is excess inventory beyond what is needed to meet expected demand. Both directly hurt profitability by tying up capital, consuming warehouse space, and often requiring deep discounts for clearance. Monitoring competitor stock levels helps prevent overstock by revealing when market-wide supply exceeds demand in a category.

Stockout costs include lost sales revenue, customer acquisition costs wasted on visitors who could not buy, damage to search rankings from listing suppression, and long-term customer attrition if shoppers find alternatives. Holding costs include warehousing fees, capital opportunity cost, insurance, and depreciation risk. Studies consistently show that stockout costs are 2-5x higher than equivalent holding costs in ecommerce, making under-stocking more expensive than moderate over-stocking for most product categories.
