The 5 Concrete Benefits of an Omnichannel OMS: Revolutionize Your Retail!
By Charlotte Journo-Baur, Founder of WISHIBAM
In a world where the boundaries between physical and digital commerce increasingly blur, the question is no longer if you should adopt an omnichannel strategy, but how to implement it effectively. What are the concrete benefits of an omnichannel OMS? I hear this question daily during my conversations with retail directors seeking solutions to transform their business model.
After guiding hundreds of retailers through their digital transformation, I can assure you that the omnichannel Order Management System (OMS) represents the backbone of high-performing retail today. It’s not just a technological tool, but a strategic lever that redefines the shopping experience and optimizes your entire value chain.
In this article, I’ll share the five tangible benefits an omnichannel OMS brings to your business, illustrated with concrete examples and data. You’ll discover how this solution can not only meet the expectations of 2025’s consumers but also generate substantial savings while boosting your revenue.
Understanding Omnichannel OMS: The Brain of Your Retail Ecosystem
The omnichannel OMS functions as the central nervous system of your retail organization. It’s a platform that centralizes and orchestrates all orders, regardless of the purchasing channel used by the customer: e-commerce, marketplace, mobile app, or physical store.
In practice, imagine a customer who spots a product on your website, reserves it via the mobile app, then decides to pick it up in-store. Without an omnichannel OMS, each interaction would be managed by separate systems, creating information silos and multiplying error risks. With an OMS, the entire journey becomes seamless and transparent, both for the customer and your teams.
Key Data:
- 73% of consumers now use multiple channels during their purchasing journey (McKinsey).
- There has been a 40% increase in purchase journeys involving at least three different channels since the pandemic.
An omnichannel OMS is therefore no longer a luxury but a necessity to address this new retail reality.
The Current Retail Context: Adapt or Disappear
The retail sector is currently experiencing an unprecedented transformation. Consumer expectations are evolving at breakneck speed, driven by technological innovations and new players who are redefining customer experience standards.
Did you know?
- 67% of European consumers now expect a completely seamless shopping experience between physical and digital channels (Deloitte, 2025).
- 82% of millennials and Generation Z see omnichannel seamlessness as a deciding factor for choosing a retailer.
I recently spoke with the digital director of a major fashion chain who told me: “Previously, we thought in terms of separate channels. Today, our customers no longer make this distinction – they simply want to buy our products in the way that suits them best at any given moment.”
This reflection perfectly summarizes the challenge retailers face.
- Retailers who have adopted a truly omnichannel approach record an average 15% increase in revenue.
- These businesses also see a 30% improvement in customer retention rates (Forrester Research).
Optimizing Customer Experience: The Fulfilled Promise of Omnichannel
The most visible impact of an omnichannel OMS manifests in the customer experience. By centralizing inventory and order information, you provide your customers with real-time visibility on product availability, regardless of the channel they use.
- Customers can instantly check nearby store availability, reserve online, or request home delivery depending on stock location.
- 43% of consumers cite convenience and 41% cite speed as critical satisfaction factors (IBM).
Real-Life Impact: A home decor retailer with 45 stores in France experienced a 28% increase in conversion rate post-OMS deployment, thanks to the ability for customers to check real-time product availability per store—drastically reducing frustration about out-of-stock items.
- Omnichannel OMS enables services like ship-from-store, click & collect, or in-store returns for online purchases.
- 76% of French consumers expect to be able to return an online purchase in-store (FEVAD, 2023).
Operational Efficiency and Cost Reduction: The Financial Argument
Beyond improving customer experience, the omnichannel OMS generates substantial economic benefits. Centralizing inventory and order data enables logistical optimization that translates into concrete savings.
Inventory Optimization
- A unified inventory view helps reduce dormant stock and optimizes inventory levels.
- Retailers using an omnichannel OMS have reduced their storage costs by 15–20% on average (Accenture).
Example: A bookstore chain reduced its stock by 22% and simultaneously increased service rate by 17% using our OMS, by turning each store into a mini logistics hub for online orders—cutting the need for centralized warehousing and accelerating deliveries.
Logistics and Order Fulfillment Optimization
- Preparing orders closer to the customer (ship-from-store) reduces transportation costs by 25% on average (Capgemini).
A logistics director of a sports retailer disclosed: “Before implementing our OMS, we sometimes shipped a product from our central warehouse when it was available in a store just steps away from the customer. These inefficiencies cost us thousands of euros each month.”

FAQ: Everything You Need to Know About Omnichannel OMS
What’s the difference between a traditional OMS and an omnichannel OMS?
A traditional OMS manages orders from a single channel (typically e-commerce), while an omnichannel OMS centralizes and orchestrates orders from all channels (web, mobile, store, marketplace). This unified vision allows for coherent management of the customer experience and global optimization of operations.
How long does it take to implement an omnichannel OMS?
Implementation time typically varies between 8 and 16 weeks, depending on your IT system’s complexity and number of sales points. At Wishibam, our accelerated methodology enables deployments in 12 weeks on average.
What’s the typical return on investment for an omnichannel OMS?
Our clients generally see a positive ROI within 6–12 months post-implementation, driven by increased revenue (15–25%), reduced logistics costs (15–20%), inventory optimization (10–15%), and improved conversion rates (20–30%).
