5 Secrets to Preventing Stockouts with an OMS
By Charlotte Journo-Baur, founder of WISHIBAM
Have you ever felt that gut-wrenching frustration when a customer leaves your store empty-handed because the product they wanted wasn’t available? This situation, dreaded by all retailers, isn’t inevitable. In 2023, stockouts still cost retailers nearly $1 trillion annually worldwide, according to the IHL Group. Behind these staggering figures lie disappointed customers, lost sales, and damage to brand reputation.
How can you reduce stockouts with an OMS? That’s the question I asked myself a few years ago before developing a solution that is now transforming daily operations for numerous retailers.
In this article, I’ll share practical strategies that have proven effective in the field and show you how a well-implemented Order Management System can become your greatest ally in putting an end to stockouts.
Understanding the Consequences of Stockouts in Retail
The Impact of Stockouts on Customer Experience and Sales
Every stockout is a double loss: we lose the immediate sale and potentially the customer for good.
This comment, which a retail chain director recently shared with me, highlights the true cost of stockouts. According to a McKinsey study, 30% of consumers switch to competitors after encountering a stockout. Even more concerning is that 70% of them change their long-term purchasing behavior after several negative experiences.
The financial stakes are high. Retailers lose an average of 4.1% of their annual sales due to stockouts. For a store with €10 million in revenue, that amounts to €410,000 in lost revenue each year—not to mention the ripple effect on customer loyalty.
The problem becomes more acute during promotional periods. 63% of consumers are particularly dissatisfied when a promoted product is out of stock (Retail Dive). This sense of a “broken promise” can seriously damage trust in your brand.
Common Causes of Stockouts
But why do these stockouts keep happening? I’ve identified three main causes:
- Inaccurate demand forecasting: Without powerful analytical tools, predicting future needs becomes a matter of guesswork. As a supply chain director once said, “Before we had an integrated system, our forecasts were more like guesses than analyses.”
- Lack of inventory visibility: Manual inventory counts, “phantom” stock, and products that appear unavailable create dangerous blind spots—a breeding ground for stockouts.
- Desynchronization between sales channels: Today, omnichannel retailing adds to the complexity. Without a central system, it’s easy to sell the same item twice—both online and in-store—leading to errors and customer dissatisfaction.
What if I told you there’s a solution that addresses all three pain points at once?
The Crucial Role of an OMS (Order Management System) in Inventory Management
How an OMS Optimizes Inventory Visibility and Management
An Order Management System (OMS) isn’t just another logistics software solution. It’s the brain that coordinates your product and order flows. With an OMS, you get a real-time view of your inventory—whether it’s in the main warehouse, in transit, or on the sales floor.
The OMS acts as the conductor, coordinating all your sales channels. When a customer makes a purchase on your website, the information is updated across all platforms instantly. No more selling the same product twice!
What sets a modern OMS apart is its predictive power. By leveraging artificial intelligence and machine learning, these platforms refine forecasts by analyzing historical sales data and taking into account seasonality, trends, and even weather conditions.
Example: A ready-to-wear brand using our OMS reduced stockouts by 37% during sales, thanks to predictive alerts that triggered restocking or transfers at just the right time.
Can an OMS adapt to all types of retail?
Absolutely. From small independents to national chains, a modern OMS scales to your needs. The main difference is the complexity of the implementation and feature set.
Case Studies: Companies That Transformed Their Inventory Management with an OMS
Here are two stories that illustrate the power of the OMS:
- Maison Élégance, a high-end home décor retailer, reduced stockouts by 42%, increased conversion rates by 18%, and decreased dormant inventory by 23% after implementing an OMS. The key? A unified view of inventory and strategic internal transfers.
- SportLife (sports goods): By keeping 20% of their collection “on hold” and allocating it based on early sales trends, they saw a 56% decrease in new product stockouts and a 14% increase in revenue during product launches. The OMS paid for itself in just 7 months.
A recent Aberdeen Group study shows that high-performing OMS users experience:
- +22% customer service rate
- −17% in storage costs
- +19% inventory turnover
The bottom line? The numbers don’t lie—but the choice of OMS and how you implement it make all the difference.
Wishibam: Your Partner for Comprehensive Omnichannel Digitalization
Why Choose Wishibam for Your Omnichannel Strategy
When I founded Wishibam, my vision was simple: to build a solution that addresses real-world retail challenges. Our OMS was created by retailers, for retailers, with a deep understanding of the realities on the ground.
Our strengths:
- Flexibility: We tailor our OMS to your processes—not the other way around.
- True omnichannel: It’s more than just connecting e-commerce to physical stores. Every customer touchpoint becomes a potential sales opportunity. Sales staff can view inventory across all channels; customers can order online and pick up in-store (or vice versa).
- Unified platform: No more isolated “partial solutions.” Our platform eliminates information silos.
- European data sovereignty: 100% European, GDPR-compliant—you remain in control of your data.
Testimonials and Concrete Results: Numbers That Speak for Themselves
- Galeries Lafayette: After implementing our solution, the company saw a 53% reduction in stockouts, a 27% increase in cross-store sales, and sales associates saved 2.5 hours each day.
- Spring: By transforming stores into logistics hubs (“Ship From Store”), they reduced perceived stockouts by 47%, shortened delivery times by 1.2 days, and increased the utilization of “dormant” inventory.
“Before Wishibam, I was losing 15 sales a week due to stockouts. Now, even if a product isn’t in my store, I can get it from another store or the warehouse. My salespeople are superheroes in our customers’ eyes!”
These are not isolated cases. On average, our clients report:
- 50% fewer stockouts
- +15–20% average basket size
- ROI achieved in less than 12 months
But beyond the numbers, it’s about improving the customer experience. When salespeople say “yes” instead of “sorry, we’re out of stock,” it completely changes how your brand is perceived.
Conclusion: Turn Your Stockouts into Opportunities
Stockouts are no longer inevitable in the digital age. With a powerful OMS like Wishibam’s, they can even become opportunities to demonstrate your agility and commitment to customer service.
I have seen too many retailers view inventory management as merely a logistical matter, when in fact it is a strategic one that directly impacts customer experience and profitability.
The question is no longer “Do you need an OMS?” but “When and how will you implement it to stay ahead of your competitors?” In a market with shrinking margins where every sale counts—can you afford to lose customers due to avoidable stockouts?
Don’t wait until the next stockout to take action. Contact us today and discover how our OMS can turn every customer’s interest into a successful sale.
FAQ: Everything You Need to Know About Reducing Stockouts with an OMS
What is an OMS, and how does it differ from a traditional ERP?
An OMS (Order Management System) is a solution designed to manage orders and inventory across all sales channels. Unlike an ERP system, which covers all business processes, the OMS specifically coordinates sales and logistics operations, providing unified, real-time visibility into inventory and orders.
How long does it take to implement an OMS and see the first results?
Implementing Wishibam’s OMS typically takes 2–4 months, depending on the complexity of your ecosystem. Initial results are visible as early as the first month, with a noticeable reduction in stockouts. ROI is generally achieved within 6–12 months.
Is an OMS suitable for small businesses or only large retailers?
Modern OMS solutions like Wishibam’s can be scaled to fit any size organization. We offer modular versions for smaller organizations that include essential features and can be expanded as needed. Your investment aligns with your specific needs.
How can an OMS help manage seasonal peaks and promotions?
The OMS uses AI to analyze historical sales data and predict spikes in demand. It automatically adjusts restocking thresholds, suggests pre-orders, and facilitates transfers between stores during peak periods. For promotions, it sets aside inventory for high-demand products.
Does Wishibam’s OMS integrate with my existing systems?
Absolutely. Our OMS is designed for easy integration with your ERP, CRM, e-commerce, POS, WMS, and more. We provide standard connectors for major solutions and develop custom integrations when needed.
What key metrics should I track to measure the OMS’s impact on stockouts?
Key performance indicators (KPIs): service rate (requests fulfilled immediately), stockout rate, inventory turnover, and average replenishment time. Our dashboard enables real-time monitoring and rapid identification of areas for improvement.
