Abstract: A real-time dynamic pricing system and method is provided, which includes a user interface, scraping and analytics components, and a batch processing server. Using the pricing system, a seller defines a product that is sold via the seller's webstore and another webstore that competes with it. The pricing system then configures a scraper based on the competing webstore's site layout. The scraper, executing in the cloud, determines whether the product is offered for sale through the competing webstore by scraping data from one of its webpages. If the scraper finds an exact product match, the scraper stores the data attributes in a data store accessible to the dynamic pricing system, and creates a price data point from the data attributes. Once the pricing system has compiled sufficient pricing data, the pricing system estimates an optimal price for the product by applying a user-specified pricing rule to the pricing data.
