Wave Picking

Wave picking organises the day's orders into scheduled batches (waves) that are released to the warehouse floor at specific times. Each wave typically corresponds to a carrier cut-off time, delivery route, or priority level. All orders in a wave are picked simultaneously, then consolidated, packed, and staged for dispatch together. This contrasts with continuous picking, where orders are released individually as they arrive.

Wave picking brings structure and predictability to warehouse operations. By aligning pick waves with carrier schedules, warehouses ensure that orders are ready when trucks arrive. It also enables labour planning — managers know how many pickers are needed for each wave based on order volume. For operations serving multiple delivery windows (morning, afternoon, express), wave picking ensures each batch is processed on time.

A WMS automatically assigns orders to waves based on rules: carrier cut-off times, delivery zones, order priority, and available labour. Short-wave cycles (every one to two hours) suit e-commerce operations with frequent carrier pickups. Longer waves (two to three per day) suit B2B distribution with fewer, larger shipments. The key metric is wave completion rate — the percentage of orders in each wave that are picked, packed, and staged before the cut-off time.
