Abstract: Among other things, product data is repeatedly communicated from an application on a device associated with a retail location to a server of a platform controlled independently of the application on the device. The product data identifies (a) current numbers of units of products available for retail customers at the retail location and (b) purchasing behavior of retail customers of the retail location with respect to combinations of the products. The retail location is repeatedly restocked with additional units of products to maintain the products in an in-stock state, the additional units have been received in deliveries made from one or more upstream product distribution entities based on predictions facilitated by the server of future demand for the products by retail customers of the retail location.
