A computer-implemented method for balancing workload among one or more locations is disclosed. The method may comprise: receiving data associated with a workload forecast for a first location and a second location, the data comprising a number of orders expected to be received for the first and second locations for a predetermined period of time; determining a first set of ratios of workload forecast for the locations relative to a first sum of the workload forecast for the first and second locations, the first set of ratios comprising at least a first forecast ratio for the first location and a second forecast ratio for the second location; receiving electronic orders for the predetermined period of time, the electronic orders comprising one or more groups of items and being assigned to one of the locations; and reassigning a first subset of electronic orders for the first location to the second location.
