The fulfillment process of retrieving (picking) items from warehouse storage and packaging (packing) them for shipment.
Pick and pack is the core operational process inside a fulfillment center: workers (or automated systems) receive an order, locate and retrieve (pick) each item from its storage location, and then assemble and package (pack) the items for shipment. This process sounds simple but is the primary driver of cost, accuracy, and speed in any fulfillment operation.
Picking strategies vary by operation: discrete picking (one order at a time), batch picking (multiple orders simultaneously), zone picking (workers assigned to specific warehouse sections), and wave picking (coordinated batch release based on carrier pickup times). The right strategy depends on order volume, SKU count, and facility layout.
Pick accuracy — the percentage of orders fulfilled without errors — is the single most important quality metric in fulfillment. Industry standard is 99.5% or higher. A 1% error rate means 1 in every 100 customers receives the wrong item, which directly generates returns, refunds, and negative reviews.
An order for a blue t-shirt (size M) and a black cap comes in at 2pm. A picker receives the order on their scanner, walks to bin A-14 to retrieve the shirt, then bin C-07 for the cap, hands both to a packer who places them in a mailer with a packing slip, and applies a USPS label for next-day delivery.
99.5% is the industry minimum standard; top 3PLs achieve 99.9%+. At 500 orders/day, a 99.5% accuracy rate means 2-3 errors per day — each requiring a reshipping cost and a frustrated customer.
3PLs typically charge a base pick fee per order ($0.50–$2.00) plus a per-item fee for additional items ($0.10–$0.50 each). Some include packing materials in the per-order fee; others charge separately for boxes, mailers, and packing materials.
