# The 5 Truths No One Tells You About OMS (and Why Retailers Are Paying the Price)
*By Charlotte Journo-Baur, Founder of WISHIBAM*
In a world where customer experience has become the new currency of retail, **Order Management Systems (OMS)** are now at the heart of all successful omnichannel strategies. Yet behind the enticing promises of traditional solutions lie realities that few providers dare to address head-on. I have guided dozens of retailers through their digital transformation, and I see the consequences of choosing the wrong OMS every day: a loss of agility, technological dependence, and ultimately, a deterioration in the customer experience. This article sheds light on these uncomfortable truths and offers an alternative vision—one that is independent and centered on the real needs of European retailers.
## I. Why the WHO Has Become the Strategic Hub of Omnichannel Retail in 2025
### A. The Surge in Customer Expectations: Immediacy, Seamlessness, Transparency
Consumers in 2025 will no longer tolerate friction. According to the 2024 Retail Pulse study, 78% of customers abandon their shopping carts when faced with incorrect inventory information or an imprecise delivery timeframe. The pandemic has permanently cemented new habits: 67% of consumers now use at least three different channels to complete a purchase (McKinsey, 2023).
This revolution in customer expectations is built on three fundamental pillars:
– **Immediacy**: 82% of customers expect instant confirmation of product availability
– **Seamlessness**: 74% want to be able to switch from one channel to another without interruption
– **Transparency**: 91% want to know the status of their order in real time
These requirements are radically changing the retail landscape. A customer who is torn between your store and a competitor’s will choose the one that offers the best visibility into product availability and delivery options. In this context, having a **robust and responsive OMS** is no longer a competitive advantage but a matter of survival.
### B. The WHO, or How to Coordinate Inventory, Orders, and Customer Commitments in Real Time
The **Order Management System** has become the invisible conductor of the omnichannel experience. Contrary to popular belief, an OMS goes far beyond a simple order management tool. It serves as the central nervous system that synchronizes all information and merchandise flows.
An effective OMS performs three critical functions:
1. **Inventory Consolidation**: It aggregates inventory across all channels (stores, warehouses, suppliers) in real time to provide a single, reliable view
2. **Intelligent Order Orchestration**: It determines the optimal shipping location based on multiple parameters (proximity, stock levels, logistics costs)
3. **Customer Promise Management**: It ensures consistency between what is promised and what is delivered
According to Forrester Research, retailers equipped with a next-generation OMS see an average 24% increase in their omnichannel revenue and an 18% reduction in logistics costs. But be careful: not all OMS systems are created equal, and differences in performance can have major consequences for your business.
## II. The Limitations of Traditional OMS Solutions in Addressing Sovereign and Operational Challenges
### A. Dependence on U.S. Tech Giants: A Risk to Data and Competitiveness
The OMS market is currently dominated by U.S. players who impose their standards, business models, and visions of retail. This dominance poses several fundamental challenges for European retailers.
First, **data sovereignty** is compromised. By entrusting the management of your inventory, orders, and customer information to these platforms, you lose control over strategic assets. According to a KPMG study (2024), 73% of European retailers now view their data as a critical competitive advantage, but paradoxically, 67% of them entrust it to service providers outside Europe.
Second, these standardized solutions **ignore the specific characteristics of the European market**:
– Diversity of national regulations (VAT, consumer law)
– Complexity of distribution networks (franchisees, affiliates, branches)
– Specific expectations of European consumers
A digital director at a French ready-to-wear retailer recently told me: “*We invested more than one million euros in an American OMS that imposed its processes on us instead of adapting to ours. The result: two years of additional development and a degraded customer experience.*”
### B. Integration Complexity, Lack of Flexibility: When Retailers Lose Control of Their Own Network
Implementing a traditional OMS is often like running an obstacle course. The numbers speak for themselves: according to the 2024 Retail Tech Barometer, 62% of OMS implementation projects exceed their initial timelines, and 58% exceed their allocated budgets.
This complexity can be attributed to several factors:
– **Monolithic architecture**: Many OMS systems were designed more than 10 years ago and struggle to adapt to modern technology ecosystems
– **Laborious integrations**: Connecting to existing systems (ERP, POS, WMS) requires costly custom development
– **Operational rigidity**: Processes are often inflexible and difficult to adapt to the specific needs of each retailer
The operational consequences are significant. A **poorly integrated OMS** can lead to:
* Undetected stockouts (average cost: 4% of annual revenue)
* Unfulfilled customer promises (impact on NPS: -12 points on average)
* An inability to rapidly deploy new omnichannel services
As the CIO of a home decor retailer explained to me: “*Our OMS has become a gilded cage. Every change requires the vendor’s involvement, with delays and costs that hinder our commercial agility.*”
## III. Wishibam, the independent OMS platform designed for European retailers
### A. A solution designed with and for merchants: real-world examples, feedback from the field, and measurable results
At WISHIBAM, we’ve taken a different approach from traditional methods by building our **sovereign ERP** based on the actual needs expressed by European retailers. This collaborative effort has resulted in a platform that precisely addresses the operational challenges of unified retail.
Let’s take the example of Galeries Lafayette, which has rolled out our solution across its entire network. The results speak for themselves:
– **+32%** increase in omnichannel sales in 6 months
– **-41%** reduction in out-of-stock incidents reported by customers
– Full deployment in just 12 weeks, compared to 9 to 18 months for competing solutions
Another notable example is a multi-franchise sports retailer that sought to unify its network without imposing a cumbersome system on its partners. Our modular approach allowed for the gradual integration of stores, yielding tangible results:
* A 27% increase in average basket size thanks to visibility into inventory across the entire network
* An 18% reduction in logistics costs through supply chain optimization
* Customer satisfaction up by 22 points (NPS)
These successes stem from our philosophy: **the OMS must adapt to the retailer, not the other way around**. Our platform therefore offers:
1. Modules that can be activated based on your needs and level of maturity
2. Native integration with major European systems
3. Go-live within weeks, not months or years
### B. Technological Sovereignty, Operational Agility: Wishibam Empowers Retailers and Regions
**Technological sovereignty** is not just a geopolitical issue—it’s a concrete business challenge. By choosing a European OMS like WISHIBAM, you retain complete control over your data and processes.
Our platform is hosted in Europe, in data centers that comply with GDPR requirements and the highest security standards. But beyond this technical aspect, our entire approach is designed to empower retailers:
– **Data Governance**: You retain ownership and decide how your data is used
– **Guaranteed Scalability**: Our API-first architecture makes it easy to add new features
– **Operational Independence**: Our customers can configure most settings themselves without external assistance
This philosophy translates into tangible benefits for local business communities. In Annecy, our platform has connected 87 independent retailers within a unified omnichannel ecosystem, creating a “local Amazon” that generated €3.2 million in additional revenue in 2023.
As the director of digital transformation at a home improvement retailer points out: “*With WISHIBAM, we finally have an OMS that understands our European challenges and allows us to innovate at our own pace, without having to rely on a roadmap decided in Seattle or San Francisco.*”
## Conclusion: Take Back Control of Your Omnichannel Destiny
At a time when omnichannel retailing is no longer an option but a vital necessity, your choice of OMS directly determines your ability to meet consumer expectations and differentiate yourself from the competition. Traditional solutions—often American and designed for other markets—impose their own limitations and create dangerous dependencies.
WISHIBAM offers a robust, agile solution tailored to the specific needs of European retailers. Our platform does more than just manage your orders—it puts you back in control of your omnichannel ecosystem and lets you innovate at your own pace.
In a world where every customer interaction counts, where every piece of data is critical, and where agility makes the difference between success and failure, can you really afford to entrust the core of your omnichannel strategy to a system that wasn’t designed with you in mind?
The answer lies in your hands, and we're ready to support you through this crucial transformation.
