Systems and methods are provided for monitoring and enforcing price parity. In one implementation, a computer-implemented method monitors price parity. The method includes generating, by a server, a task related to pricing of an item. The server receives, in response to the task, a first price and a second price of the item. The first price corresponds to an offering price of the item by a third-party seller via a sales channel of a retailer and the second price corresponds to an offering price of the item by the third-party seller via a sales channel of the third-party seller. The server evaluates whether the second price violates a price parity rule, based on at least a comparison of the first price and the second price.
