Systems and methods for use in permitting merchant to manage fraud prevention rules are disclosed. One exemplary method includes causing at least one settings interface to be displayed to a merchant via a sales platform. The method also includes receiving, by a computing device, via the at least one settings interface, a merchant-specific selection of a prescribed action relating to transactions, at the merchant and receiving, by the computing device, a merchant-specific selection of a fraud prevention rule associated with the prescribed action. The fraud prevention rule defines merchant-specific criteria relating to the transactions. In addition, the method includes appending, by the computing device, the fraud prevention rule to a data structure, in association with the merchant, whereby the prescribed action is effected when a transaction to the merchant violates the criteria defined by the fraud prevention rule.
