Scans of a selected product on shelves of a retail store are obtained and the scans are transmitted over a network via a transceiver circuit. A perpetual inventory (PI) value is stored for a selected product in a database. A data structure includes a first category and first actions programmatically linked to the first category. The first actions include instructing an autonomous vehicle to find the selected product, instructing an employee to find the selected product, and adjusting the PI value of the selected product. When the selected product is out-of-stock and when the PI value is greater than a predetermined threshold, one or more of the first actions associated with the first category are performed.
