Pick and Pack: Process, Methods & Benefits

Pick and pack is the warehouse process of retrieving the items listed on a customer order from their storage locations (picking) and preparing them for dispatch in suitable packaging (packing). It is the core operational step inside order fulfilment, sitting between order receipt and handover to the carrier.

The term is also used to describe a service offered by third-party logistics providers, where the provider stores a client’s inventory and picks, packs, and ships orders on its behalf.

Why Pick and Pack Matters in Supply Chain

Pick and pack is where most fulfilment cost and most fulfilment error originate.

Labour cost: Picking is typically the single most labour-intensive activity in a warehouse, and travel time between locations accounts for a large share of a picker’s working hours.
Order accuracy: Wrong item, wrong quantity, and missing item errors almost all occur at the pick or pack stage. Each one creates a return, a replacement shipment, and a refund or credit.
Dispatch cut-off: Picking and packing throughput determines how many orders can clear the dock before the carrier pickup, which in turn sets the delivery promise.
Damage and shipping cost: Packing decides whether goods survive transit, and the pack size and weight directly determine the courier charge, since carriers bill on volumetric or actual weight.
Scalability: The picking method that works at low volume becomes the bottleneck as order volume grows.

Process of Picking and Packing

Picking

The order is released to the warehouse and a pick list or pick task is generated, usually by a warehouse management system (WMS).
The pick list sequences locations to minimise travel distance rather than listing items in order entry sequence.
The picker travels to each location and picks the required quantity, scanning the item or location barcode to confirm the pick.
Picked items are placed in a tote, carton, or trolley and moved to the packing station.

Packing

Items are verified against the order, normally by scanning each unit at the pack bench.
A suitable box, mailer, or carton is selected based on dimensions and fragility.
Void fill or protective material is added where needed.
The parcel is sealed, weighed, and dimensioned.
The shipping label, invoice, and any required documents are generated and attached.
The parcel is sorted to the correct carrier lane for dispatch.

Common picking methods

Discrete (piece) picking: One picker completes one order end to end before starting the next. Simple and accurate, but involves the most travel per order. Suits low volumes and large multi-line orders.
Batch picking: One picker collects the same item for several orders in a single trip, then the quantities are split by order at a sorting or packing stage. Efficient where many orders contain the same SKUs.
Zone picking: The warehouse is divided into zones, each with an assigned picker. Orders move between zones or are consolidated afterwards. Suits large facilities with wide SKU ranges.
Wave picking: Orders are grouped into timed releases aligned to carrier pickup schedules or dispatch cut-offs. Used to synchronise warehouse output with transport.
Cluster picking: The picker carries several order containers at once and picks into each as they travel. Reduces travel for small single-line and two-line orders.

Many warehouses combine methods, for example zone-batch picking, with the method selected by order profile rather than applied uniformly.

Key Components of Picking and Packing

Pick list or pick task: The instruction set telling the picker what to collect and in what sequence.
Pick face and slotting: Where items are positioned. Fast-moving SKUs placed close to the packing area cut travel time significantly.
Barcode scanning or RF devices: Confirm the correct item and location at pick and at pack, which is the main defence against picking errors
Packing station: Equipped with box sizes, void fill, scales, and a label printer.
Packaging selection: Right-sizing cartons reduces both material cost and volumetric shipping charges.
Quality check: Verification of picked items against the order before sealing.

Pick and Pack Example in Supply Chain

A home products brand fulfils around 800 orders a day from a warehouse in Bhiwandi. Most orders contain one or two items.

Originally each picker handled one order at a time, walking the full aisle run for a single item. Throughput was limited and travel time dominated the day. The warehouse moved to cluster picking for single and two-line orders, with pickers carrying a trolley of eight order totes and a sequenced pick path, and kept discrete picking only for large multi-line orders.

The brand also reslotted its top 50 SKUs into the aisles nearest the packing stations, since those SKUs accounted for a large majority of daily picks. Picks per hour rose, and more orders cleared the evening courier cut-off without additional staff.

FAQs

Q1. What is the difference between picking and packing?
Picking is collecting the ordered items from storage. Packing is verifying, protecting, labelling, and sealing them for dispatch. They are sequential steps, usually carried out by different staff at different stations.

Q2. Which picking method is best?
There is no single best method. It depends on order profile. Single-item orders in high volume favour batch or cluster picking. Large multi-line B2B orders usually favour discrete or zone picking. Most warehouses use a mix.

Q3. How can pick and pack accuracy be improved?
Barcode scanning at both pick and pack, clear location labelling, accurate slotting, a verification step before sealing, and measuring accuracy by picker so that errors can be traced and addressed.

Q4. What is pick and pack as a service?
An arrangement where a third-party logistics provider holds a client’s inventory and performs picking, packing, and dispatch for each order, charged typically per order plus per additional line item and storage.
