Abstract: A non-transitory processor-readable medium stores code representing instructions to be executed by a processor. The code stored in the medium includes code to cause the processor to receive a first signal indicating a quantity of an item listed on a website of a first marketplace from a set of marketplaces. The item is listed on a website of each marketplace from the set of marketplaces. The code stored in the medium includes code to cause the processor to change, based on the first signal, an inventory parameter associated with the item from a first value to a second value. The code stored in the medium includes code to cause the processor to send, to a device of each marketplace, a second signal indicating the updated inventory parameter such that the item remains listed on the web site of each marketplace until the second value is zero.
