Breaking down the cost of a picking error
The direct cost includes processing the claim, generating a return, checking the returned product, preparing the correct item and shipping it a second time. Added to this are less visible costs: customer support time, immobilized stock, a possible commercial discount, a product damaged during return, service penalties and lost productivity in the warehouse.
Why picking errors remain frequent
Sulco Lancer cites typical picking error rates of 1 to 3 % in warehouses. This level may seem low, but it becomes significant as volume increases. Out of 1,000 lines prepared, that represents 10 to 30 potential errors. Similar products, nearby locations, workload peaks, fatigue and the absence of system confirmation increase the risk.
Impact on the customer relationship
The customer does not see the internal process; they see a broken promise. A picking error can create a delay, a mandatory return, a wait for the right product or a cancellation. Even when the company corrects the issue quickly, trust declines. For some B2B customers, repeated errors can be enough to call the supplier into question.
Reducing errors at the source
Technical levers all aim to prevent the wrong pick before it leaves the warehouse: product and location scanning, quantity control, packing verification, voice or light-directed systems, weighing and priority rules. The best return is the one that never happens because the error was blocked at the moment of picking.
13 % of margin per picking error is a simple indicator to turn into annual cost: number of errors × average impacted margin. This view makes visible a cost often scattered across logistics, support and sales. Prevention through scanning and systematic control is therefore a direct lever for protecting margin.
