A system-directed single line pick batching is described. In an example implementation, the system may receive data describing a set of orders including SKU identifiers associated with items in the orders, identify an eligible cart, and assign a location to a task queue of the cart based on the location being associated with a particular SKU identifier. In some instances, the location or SKU identifier may be determined based on an order with a certain quantity of different SKU identifiers. In some instances, the system may navigate the cart to the location and instruct the item to be picked from the location. In response to completion of the pick of the item, the system may navigate the cart to an end point.
