A picker can select the wrong product, size, colour or quantity even when the order itself is correct. If the error is found before dispatch, the operation has an opportunity to fix it without involving the customer. The important part is to correct both the physical order and the inventory trail rather than quietly swapping items at the packing bench.
Stop the affected order at the point of discovery
Keep the parcel or tote from progressing while the discrepancy is checked. Continuing packing around a known mismatch increases the chance that the incorrect item reaches dispatch or becomes mixed with another order.
Compare the picked item with the order record
Use the operation's normal product identifiers and order information to confirm what should have been picked. Similar packaging can make a visual description unreliable, especially where variants differ only by size or specification.
Identify whether the error affects stock records
Determine how the warehouse system recorded the original pick. The physical correction and the system correction should follow the retailer's established process so inventory does not remain reduced against the wrong product.
Return the incorrect item through the normal route
Do not simply place a mis-picked product on the nearest shelf. Return it to the appropriate location or exception process so its availability and physical position remain traceable.
Pick the correct item against the same order
Once the discrepancy is resolved, complete the authorised replacement pick without creating a duplicate customer order. The original order history should continue to represent the fulfilment activity.
Recheck the parcel before release
Confirm that the corrected contents now match the order before allowing packing or dispatch to continue. This is particularly useful when the mis-pick involved several similar items or quantities.
Record recurring mis-pick patterns
If the same products or locations generate repeated errors, retain enough operational information to investigate the pattern. Product similarity, location layout, labelling or picking instructions may deserve review.
Use findings to improve the picking process
Look for practical changes supported by the evidence rather than assuming every error is individual carelessness. Better location separation, clearer identifiers or workflow adjustments can sometimes reduce repeat mistakes without adding unnecessary checks to every order.
