Error-Free Order Picking: Save Time & Money

Order Picking in E-Commerce: The Linchpin of Efficient Logistics

In fulfillment, order picking decides everything: speed, accuracy, customer satisfaction — and ultimately your margins. In E-Commerce especially, where customers expect smooth delivery within 24 hours, every move counts. Sloppy work here costs you twice — in returns, support workload, and lost customers.

In this article we'll show you:

  • What order picking actually means,
  • Which methods work in practice,
  • How to make your pick processes more efficient,
  • And which tools & systems help you save time and avoid errors.

Whether you pick yourself or use a fulfillment partner — with the right processes you get more out of every shipping order.

What exactly is order picking?

Order picking — also called "picking" — describes the process of taking items out of inventory and assembling them for a specific customer order. It's one of the central steps in fulfillment — and one of the most labor-intensive.

Here's what picking typically looks like:

  1. A customer order comes in (e.g. via an online shop).
  2. The warehouse management system automatically generates a pick list.
  3. The responsible team members head to the storage locations and "pick" the items.
  4. The goods are prepared for shipping (incl. packaging, labeling, optional inserts).

Why does this matter for you?

  • Time eater or accelerator: Picking can be your bottleneck or your accelerator in shipping.
  • Error source #1: Wrong items, double picks, or missing quantities often start here.
  • Cost factor: Efficient picking means lower cost per order.

The more precise this process is, the smoother your entire logistics chain runs — and the happier your customers will be.

Picking methods compared

In this section we'll show which picking methods are used in practice — and how they differ. Because not every solution fits every setup.

Which picking methods are out there — and how do they differ?

Manual, semi-automated, or fully automated: the right method depends on your shipping volume, product range, warehouse layout, and scaling strategy.

Here's an overview of the most important approaches:

💡 Pro tip:

For many growing DTC brands, a combination works best: manual entry (pick-by-scan) with gradual additions like zone logic or multi-order picking — depending on volume and product structure.

Common error sources — and how to avoid them

Even the best warehouse layout doesn't help if picking isn't well thought out. Here are the most common problems you'll run into in practice — and how to solve them concretely.

1. Wrong or missing items in the parcel

Cause:

  • Unclear pick lists
  • Missing plausibility checks
  • Distractions during picking

Solution:

  • Use digital pick lists with scan confirmation
  • Add a control station before packing
  • Train your team regularly & give feedback

2. Long walking paths and lost time

Cause:

  • Poorly planned warehouse structure
  • No zone logic
  • No order prioritization

Solution:

  • Store products by ABC analysis (fast movers = close to the pack station)
  • Optimize picking routes (e.g. U- or S-shape instead of zigzag)
  • Bundle order groups (batch picking)

3. Double picks or forgotten items

Cause:

  • Parallel orders without clear separation
  • Confusing storage locations
  • No real-time tracking

Solution:

  • Combine multi-order picking with a sorting system
  • Color- or number-code your pick carts
  • "Tick off" items by scan before they go into the box

4. Unmotivated or overwhelmed staff

Cause:

  • No clear KPIs
  • Unstructured onboarding
  • High time pressure, bad warehouse atmosphere

Solution:

  • Clear training concepts & performance targets
  • Intuitive tools (e.g. pick-by-scan instead of paper)
  • Ergonomic workplaces & a feedback culture that motivates

5. No real-time data visibility

Cause:

  • No system integration
  • Paper-based processes
  • No warehouse transparency

Solution:

  • Introduce a WMS (Warehouse Management System)
  • Connect to ERP & shop system
  • Dashboard for monitoring pick times, error rates & throughput

Best practices — How to optimize your order picking long-term

If you want to grow, you have to be able to scale. Order picking is one of the biggest levers for that. With the right measures, you can significantly increase throughput, accuracy, and efficiency — without driving up your error rate.

1. Introduce digital pick lists with scan functionality

Paper is yesterday. Digital pick lists on handheld devices or tablets give you:

  • Live sync with your WMS or shop system
  • Error prevention through scan checks
  • More transparency for the team

🔧 Tip: Use devices with ergonomic scanner mounts — it saves time and your wrists.

🔧 Tip: Use handheld devices that can also scan a QR code. Unlike barcodes, QR codes can carry significantly more information per scan, like the batch or expiration date of the scanned goods.

2. Organize storage by ABC analysis

Make sure fast movers are near the pack station and walking distances are reduced.

  • A products: high frequency → right up front
  • B products: medium frequency → mid-shelf level
  • C products: low frequency → further back or up/down

📊 Benefit: Fewer steps, shorter pick times, more throughput per picker.

3. Use zone picking in large warehouses

Divide your warehouse into logical zones. That way several pickers can work at the same time — without blocking each other.

➡️ Ideal for fulfillment with high SKU counts or high daily volume.

4. Use multi-order picking efficiently

Pick several orders at once, e.g. all orders containing a specific top seller. Then sort by order at the pack table.

🔁 Benefit: Higher efficiency for recurring items — ideal during peak times.

5. Get your team involved and document processes

Tech alone isn't enough — your team has to come along. Make sure you have:

  • Clear SOPs (Standard Operating Procedures)
  • Visual step-by-step guides
  • Regular feedback rounds & suggestion programs

💬 Real-world example: Pickers who are allowed to think along often deliver better optimization ideas than any external consultant.

6. Measure, improve, scale

What you don't measure, you can't improve. So track:

  • Pick times per order
  • Error rate per picker
  • Average distance per pick

🔍 Tools like a WMS or BI dashboards give you the necessary KPIs at a glance.

The role of technology & fulfillment partners

Modern order picking is more than manual pick & pack. If you want to be competitive today, you need digital systems, connected processes, and scalable logistics solutions. That's where technology — and possibly a fulfillment partner — comes in.

Digital warehouse management with a WMS

A Warehouse Management System (WMS) is the backbone of efficient picking. It controls:

  • Storage location management: items always in the optimal spot
  • Pick processes: automatic routes and zone logic
  • Live tracking: every item is traceable at any time
  • Error reduction through scanning and system checks

🎯 Result: Shorter pick times, fewer errors, more transparency — from goods receipt to shipping label.

API connection to shops, marketplaces & ERP

The better connected your fulfillment system is, the smoother every order flows:

  • Orders are imported automatically
  • Pick lists are generated in real time
  • Tracking data is sent back automatically
  • Inventory levels stay in sync

🔌 Real-world example: With an API connection to Shopify or Shopware, you can automate every pick process — no manual exports, no data loss.

Automation & robotics

Larger companies are increasingly using technologies like:

  • AutoStore (compact robotic storage cube)
  • Shuttle systems (mobile shelf pickers)
  • Mobile picking robots

These solutions are expensive to acquire — but pay off with consistently high volume, low error tolerance, and scalable growth.

Benefits of a fulfillment partner like Zenfulfillment®

If you don't want to (or can't) pick yourself, a specialized fulfillment provider can take over the entire process:

  • Automated picking
  • Scalable pick strategies depending on product and order volume
  • Seamless integration with your systems (shop, ERP, marketplaces)
  • White-label tracking & automated shipping communication

💡 Advantage: You don't have to worry about staffing, warehouse layout, or process optimization — you can focus entirely on your core business.

Bottom line: Order picking decides efficiency and customer satisfaction

Order picking is more than just an operational in-between step — it sets the pace for your entire fulfillment process. Mistakes here cost time, money, and trust. Well-structured, digitally supported pick processes, on the other hand, deliver:

  • Fast turnaround times
  • Minimal error rates
  • Happy customers who order again

Whether you store in-house or work with a fulfillment provider: with the right strategy and technology, picking becomes a competitive advantage.
