PricingHUB publishes a dynamic pricing solution in saas mode which helps retailers to optimise their price and margin. We calculate daily price recommendations necessary to achieve a business objective and within the constraints. We use an experimental methodology (AB Testing) to compute price elasticity and use it to calculate our price adjustment recommendations. We work with players such as the Fnac Darty group (European web and store deployment) or allopneus.com. Our systems optimise hundreds of thousands of SKUs and calculate more than 100,000 price recommendations per day.
