Why your warehouse is secretly burning through money

19.05.2026

5 cost drivers and how to eliminate them through warehouse optimisation.

Summary:Many warehouses are losing money every day – often without anyone noticing. The causes include inventory errors, high picking error rates, unnecessary walking distances, isolated Excel spreadsheets and analogue processes. Through targeted warehouse optimisation using modern warehouse management software such as COGLAS WEB WMS, processes can be made more transparent, errors reduced and significant costs saved. Companies benefit from improved delivery capability, faster processes and better scalability.

Why your warehouse is secretly burning money

This scenario is a reality in many companies: an employee stands in front of a storage bay, but the urgently needed pallet has vanished. The system shows that the item is in stock, yet physically it is nowhere to be found. The search begins. Meanwhile, the lorry is waiting at the loading bay, customers are waiting for their delivery, and valuable working time is being wasted.

What at first glance appears to be an isolated incident is often a symptom of fundamental inefficiencies in warehouse logistics. This is precisely where professional warehouse optimisation comes in.

Rising customer expectations, growing cost pressures and increasing complexity in the supply chain make efficient warehouse processes more important today than ever before. Those who fail to continuously optimise their processes lose their competitive edge – often gradually and unnoticed for a long time.

Below, we highlight the five biggest cost drivers in the warehouse and how companies can eliminate them through targeted warehouse optimisation.

1. Inventory errors and phantom stock lead to high follow-up costs

One of the most common causes of inefficiency in the warehouse is inaccurate stock levels. When the system shows stock that is not physically present, this results in what is known as ‘phantom stock’.

The consequences are serious:

• Staff spend valuable time searching for items
• Delivery deadlines cannot be met
• Reorders are triggered incorrectly
• Customers lose confidence in the company’s ability to deliver

Particularly critical: companies tie up capital in stock that has either been incorrectly recorded or stored in the wrong location.

Modern warehouse optimisation therefore relies on real-time transparency. Mobile data capture, barcode scanning and digital warehouse processes ensure that stock levels remain accurate and traceable at all times.

2. Picking error rates cost companies thousands of euros every year

Many companies underestimate the actual costs of picking errors. Even small errors can quickly add up to significant losses.

A real-world example:

• 1,000 picks per day
• Error rate of just 2%
• Average cost per error of 40 euros

This results in a loss of up to 200,000 euros per year – solely due to picking errors.

The actual costs arise not only from returns or subsequent deliveries, but also from:

• additional processing costs
• double shipping costs
• increased customer service costs
• damage to reputation and customer churn

Professional warehouse optimisation reduces these risks through digital picking processes, scanner guidance and automatic plausibility checks.

This significantly reduces the error rate and sustainably improves process quality.

3. Unnecessary walking distances reduce productivity in the warehouse

In many warehouses, staff walk several kilometres every day – often without adding any real value.

The reasons for this include:

• chaotic warehouse layouts
• lack of route optimisation
• poor item placement
• noABC analysis

It becomes particularly problematic when fast-moving items are stored in unfavourable locations, whilst rarely used items block valuable space.

The result:

• longer picking times
• lower productivity
• rising labour costs
• unnecessary strain on staff

Intelligent warehouse optimisation analyses movement data and dynamically optimises storage strategies. Modern WMS systems support this with:

• route optimisation
• multi-order picking
• chaotic warehousing
• intelligent storage location management

This allows walking distances to be significantly reduced and existing resources to be utilised more efficiently.

4. Excel and manual processes hinder growth and transparency

Many companies still manage their stock partly using Excel spreadsheets or paper-based processes. What may seem pragmatic in the short term becomes a significant risk in the long run.

Typical problems include:

• Lack of real-time capability:By the time the spreadsheet is updated, the physical stock has already changed.
• Isolated silo solutions:There are no automated interfaces to the online shop or the ERP system, meaning manual data maintenance is required.
• Massive loss of time:Staff have to maintain data two or three times over. This is a prime source of errors.
• No scalability:Without automatic order suggestions, your planning remains reactive and prone to errors.

The situation becomes particularly critical with growing order volumes or multiple sales channels. Without automated interfaces between ERP, the webshop and the warehouse, data silos and additional manual effort arise.

Modern warehouse optimisation therefore relies on centralised digital processes and automated data flows.

This creates complete transparency throughout the entire intralogistics process.

5. Paper-based processes hinder efficient warehouse logistics

Printed picking lists, handwritten notes and lost delivery notes are still part of everyday life in many warehouses.

However, analogue processes cause numerous problems:

• Information is lost
• Processes are delayed
• Documentation is inaccurate
• Traceability is lacking
• Decisions take longer

Especially in times of increasing demands for speed and transparency, paper-based systems become a barrier to growth.

Digital processes offer significant advantages here:

• real-time mobile data capture
• digital documentation
• transparent process chains
• faster response times

In this way, companies lay the foundations for scalable and future-proof warehouse logistics.

Warehouse optimisation with the COGLAS WEB WMS

Sustainable warehouse optimisation does not stop at individual measures. What is crucial is a system that centrally controls all warehouse processes and makes them transparent.

This is exactly where the COGLAS WEB WMS comes in.

The Warehouse Management System supports companies in:

• Managing stock in real time
• Reducing picking error rates
• Optimising walking routes
• Implementing paperless processes
• Integrating interfaces with ERP and shop systems
• to set up scalable warehouse processes

Particularly important:Many companies shy away from complex IT projects. The COGLAS WEB WMS has been specifically designed to enable rapid implementation without years of large-scale projects.

As a result, companies often see measurable efficiency gains within a short space of time.

Conclusion: Warehouse optimisation is a direct driver of your competitiveness

Every unnecessary walk, every stock discrepancy and every picking error costs money. Many of these losses remain hidden in day-to-day operations – yet they have a direct impact on productivity, delivery capability and margins.

Warehouse optimisation is therefore not an optional improvement project, but a decisive competitive factor.

The key question is no longer whether processes should be optimised, but how much longer companies can afford to accept inefficient workflows.
