Avoid picking errors during Black Friday and maximize profit

When we talk about Black Friday performance, there are some go-to metrics that nearly every e-commerce business tracks:

Conversion rate, ROAS (Return on Ad Spend), AOV (Average Order Value), return rate and of course, profit.

But one crucial metric is often overlooked: the error rate in order picking.

In other words, how many orders are shipped with mistakes: wrong items, missing items, or extras.

These errors are costly. They erode profit, strain operations, and damage customer trust. But the good news? They can be significantly reduced with a few focused initiatives without the need for a complex or costly WMS setup.

Picking errors spike during Black Week

It’s one of the busiest times of the year. Temporary staff are onboarded quickly. Hours are long, and pressure is high. Errors increase.

It’s not unusual for the error rate to climb during Black Week, exactly when margins are thinnest due to aggressive discounts and price competition.

Many businesses scale up their warehouse teams to keep up with demand. But without the right tools in place, more hands can also mean more mistakes.

What do picking errors actually cost?

Correcting an error: reshipping, compensating the customer, or absorbing lost revenue - comes at a real price. Add the time spent on administration and customer service, and the cost rises fast.

And then there’s the long-term cost: a poor customer experience that can impact retention and loyalty.

Example: How expensive is a 2% error rate on 10,000 orders?

Let’s break it down, based on a typical scenario we often see when advising businesses on best-practice fulfillment setups.

A 2% error rate may sound low. But with 10,000 orders during Black Weekend, that means 200 orders are shipped incorrectly.

Include the cost of return shipments, 15 minutes of admin and customer support per order, and the total can quickly hit €4,000–7,000.

That’s pure cost. Directly hitting the bottom line during your most competitive season.

KiMs reduced error rate from 4% to near-zero

KiMs uses our Digital Pick Paths with handheld terminals that display product images and quantities on screen.

This has reduced their picking errors from 4% to nearly 0% every single month.

That means fewer returns, more efficient workflows, and better customer experiences - delivering real impact on their business.

How to minimize picking errors in practice

You can achieve similar results with three key actions:

What you’ll need:

• Digital picking devices: scanners, tablets, or handheld terminals. (We’ve tested and recommend several in our guide to buying hardware.)
