PriceTrail is price monitoring software that tracks competitor and supplier prices across major retail platforms like Amazon, Walmart, and eBay. Product page URLs can be input into the system, which then automatically monitors prices around the clock. Custom price thresholds can be set, triggering instant email alerts when prices drop below specified targets. Interactive price history charts display trends, seasonal patterns, and pricing opportunities over time. The platform offers back-in-stock alerts for sold-out products, notifying users when items become available again. Regularly scheduled monitoring logs all price changes, capturing competitive pricing movements as they occur. Webhook and API integration allows PriceTrail to connect to other business systems, enabling automated workflows based on pricing data. The desktop-accessible platform provides continuous price surveillance and data-driven insights for informed pricing decisions.
