Systems and methods are described for managing inventory stock for variable weighted and variable priced agricultural products. A system includes: a memory device storing a data structure that relates a plurality of available base unit values and a plurality of available base unit measurement types to each type of agricultural product type; an interface controller configured to provide an interactive interface for a vendor, the interactive interface including an agricultural product type field, a base unit values field, and a base unit measurement type field; and a processor in communication with the interface controller and the memory device. An example method involves: receiving, from a vendor device via the interactive interface, a selection of agricultural product type in the agricultural product type field, and a selection of a base unit value and a base unit measurement type; and storing a marketplace record to the memory device.
