Systems and methods of managing perpetual inventory

A perpetual inventory (PI) control system, comprising:

• at least one inventory system communicatively coupled with multiple POS systems at a first shopping facility of multiple shopping facilities;
• a perpetual inventory (PI) engine control circuit communicatively coupled with the inventory system, and further configured to receive inventory information from the inventory system and sales data recorded by the multiple POS systems;
• wherein the PI engine control circuit is configured identify the occurrence of a plurality of different events each associated with a different product of thousands of different products at one of the multiple different shopping facilities, and each event corresponds to a potential inconsistency in a determined inventory count of the corresponding product;
• and for each of the events:
• identify, dependent on the event and a corresponding first product, a first set of inventory evaluation rules from multiple sets of inventory evaluation rules;
• apply the first set of inventory evaluation rules to determine a type of inventory count error relative to the determined inventory count of the first product at the first shopping facility;
• identify a second set of at least one inventory evaluation rules based on the type of inventory count error, and applying the second set of at least one inventory evaluation rules to determine an inventory adjustment action to be implemented based on the first product and the determined error type;
• and cause the inventory adjustment action to be implemented in substantially real-time to adjust the determined inventory count of the first product at the first shopping facility;
• and
• wherein the PI engine control circuit is further configured to push perpetual inventory adjustment information to multiple different inventory storage devices without a request from an external device.
