This page is for a sourcing agent, a logistics new entrant, or anyone who needs to see exactly how an order goes from located stock to a correctly packed carton ready for dispatch. This lesson mainly teaches the product flow: it shows how a pick list turns a warehouse's own located stock into an exact, checked order, and how packing confirms that the right pieces are together before the carton is sealed.
Meridian Sourcing, acting as agent in Egypt for two European buyers, is paid a 5% commission and carries a real interest in every order it places actually arriving as ordered. Delta Garments runs Order A's own 15,000-piece export run for Northline Apparel alongside its standing domestic replenishment work, a hybrid pattern common across its own factory floor. Whichever order is being picked, the same risk exists: a warehouse can have every piece correctly received and correctly located, and still ship the wrong piece if picking or packing goes wrong at the very last stage before dispatch.

| Pick error | Collecting the wrong item, wrong quantity, or wrong size against a pick list. |
| Order accuracy | The share of an order's own pieces that are correctly picked and packed, matching the pick list exactly. |
| Carton label | The label attached to a packed carton stating its own contents and destination. |
| Pack check | A verification step comparing picked items against the pick list before a carton is sealed. |
Picking means collecting the exact style, size and quantity a pick list specifies, from the locations recorded during put-away. Packing means placing those picked items into cartons correctly, confirming the contents against the pick list one more time, and applying a carton label stating the contents and destination, before sealing the carton. These are two separate checks on the same order, not one combined step, because an item can be picked correctly and still packed into the wrong carton, or packed correctly into a carton that was never actually checked against the pick list at all.
| What can differ | The shapes you will meet | Why it matters |
|---|---|---|
| A single, large export order in one style | Order A's own 15,000 T-shirts are picked as one style across a size range, so a pick error usually means the wrong size, not the wrong item entirely. | Even with one style, a size mix-up on a large order can mean hundreds of pieces going to the wrong size ratio before anyone notices. |
| Several smaller orders picked in the same shift | Meridian Sourcing's own buyers may have several smaller reorders moving through the same warehouse on the same day, each needing its own separate pick list. | Mixing pieces from two different pick lists into one carton is a common failure mode exactly because both orders are physically nearby and superficially similar. |
| A hybrid factory running export and domestic work together | Delta Garments' own warehouse staff pick Order A's own export cartons and a domestic reorder for Cedar & Co. in the same shift, from different areas of the same warehouse. | Picking discipline cannot relax for either order type; a domestic reorder shipped to the wrong shop causes the same kind of disruption as an export carton shipped to the wrong buyer. |
| An agent auditing pick accuracy on behalf of a buyer | Meridian Sourcing periodically checks a sample of Delta Garments' own packed cartons against their own pick lists before the shipment leaves, since the agent's own commission depends on the buyer trusting future orders. | An agent's spot-check exists because the buyer is not physically present to check picking and packing itself, and trusts the agent's own verification instead. |
Before Order A's own 300 cartons leave Delta Garments' own export warehouse, Meridian Sourcing's own field representative selects a sample of 15 cartons, one from each of 15 different pallets, and checks each one against its own pick list: correct size ratio, correct quantity of 50 pieces, correct carton label matching the destination port. All 15 sampled cartons match their own pick lists exactly, giving Meridian Sourcing reasonable confidence in the full 300-carton shipment without physically opening every single carton.
A single pick error inside a 5% sample is not a small problem; it implies, if the sample is representative, that hundreds of pieces across the full 15,000-piece order could carry the same error. This is exactly why a spot-check exists: to catch a systemic pick error early, from a small sample, rather than discovering it only after the full shipment has already reached the buyer.
The methodA common mistake is moving straight from picking to packing without a final check against the pick list, on the assumption that picking alone was accurate. Picking and packing are separate steps precisely because each introduces its own chance of error: an item can be picked correctly and then packed into the wrong carton during a busy shift, or two similar orders' pieces can be mixed together while several pick lists are being worked at once. What this costs Meridian Sourcing's own buyers is real: a carton packed with the wrong size ratio, discovered only when it reaches the buyer's own warehouse overseas, cannot be corrected quickly, and the cost of reshipping the correct pieces falls on whichever party's contract assigns it, often after a dispute over whose error it was.
Picking means collecting the exact style, size and quantity a pick list asks for, from the spot where it was stored. Packing means putting those collected items into a carton, checking one more time that everything matches the pick list, then sealing the carton and labelling it with what is inside and where it is going. These are two different jobs, and doing the first one correctly does not guarantee the second one is also correct, since a mix-up can happen while moving items from the picking stage into a carton. A quick check against the pick list before sealing a carton catches most mistakes while they are still cheap and easy to fix, before the carton leaves the building and any error becomes the buyer's problem instead of the warehouse's own.
During a busy shift preparing Order A's own shipment, a packer collects picked items for one carton and seals it quickly to keep pace with the rest of the team, without a final check against the carton's own pick list. The carton is labelled correctly for its destination and moves on to the next stage.
Here is the packer's own note on the shift log:
Does keeping pace with the team target justify skipping the final check against the pick list? Decide before opening the answer.
No, keeping pace does not justify skipping the final check. Two facts missing from the packer's note decide this.
First, the final check against the pick list is the only step confirming that what was actually picked matches what the pick list actually specified, and skipping it removes the last chance to catch a pick error before the carton is sealed. Once sealed, the same error can only be caught by opening the carton again, which costs far more time than the check would have.
Second, "keeping pace with team target" measures speed, not accuracy, and a fast but inaccurate packing process creates work later, when a wrong carton is discovered at the buyer's own end, that costs vastly more time than the seconds a final check would have taken. A target measured only in cartons packed per hour rewards exactly the shortcut that causes this risk.
The corrected process should include the final check against the pick list as part of the packing step itself, not as an optional extra a busy shift can skip.
Using Order A's own fixed figures:
A single mixed-up carton costs USD 160 in goods value, but correcting it after the fact adds another USD 90 in air freight for a replacement, nearly doubling the cost of the original mistake, on top of the delay to the buyer's own shop delivery while the correct pieces are in transit.
Open the course workbook's "Picking and packing" sheet. It lists a pick list's own style, size, quantity and destination for each carton, then a column confirming the final check result before sealing, flagging any pick error automatically. Enter a different order's own pick list to see how the same check applies to any shipment.

1. A packer seals a carton immediately after picking, without a final check against the pick list, to keep pace with a team target measured in cartons per hour. What risk does this actually create?
2. Meridian Sourcing samples 15 of Order A's own 300 cartons and finds 1 with a pick error. What does this single error suggest about the full shipment?
