A computer-implemented method for negotiating a price of a product for a user may comprise obtaining an identification of the user via a device associated with the user; obtaining social influence data of the user based on the identification of the user, wherein the social influence data of the user includes a net promoter score or a social ranking of the user; obtaining purchase parameter data of the user based on the identification of the user, wherein the purchase parameter data of the user includes a credit score, an income range, or a transaction history of the user; determining a user-specific price of the product based on the purchase parameter data and the social influence data using a trained machine learning model; and transmitting, to the user, a notification indicative of the user-specific price.
