Did you know the global on-shelf availability solution market is projected to grow from $3.39 billion in 2025 to a staggering $8.14 billion by 2034, with a CAGR of 10.22%?
This growth underscores how vital on-shelf availability (OSA) is for retailers and FMCG brands alike. In a competitive industry where every inch of shelf space can make or break a sale, ensuring products are always available is not just important but essential.
The on-shelf availability formula is critical for balancing demand and supply efficiently. Let’s delve into what OSA means, explore actionable strategies to optimize it, and uncover the technologies shaping its future.
Understanding On-Shelf Availability (OSA)
On-shelf availability (OSA) is a key retail metric that measures the percentage of time a product is available for purchase by customers on the shelf when they want to buy it. High OSA ensures better sales, customer satisfaction, and efficient inventory management.
What is OSA in Retail?
The formula is simple yet powerful:
OSA (%) = (Number of items available on shelf / Total expected number of items on shelf) x 100
If a retailer expects 100 units of a product to be on the shelf but only 90 are available, the OSA would be:
OSA = (90/ 100) x 100 = 90%
This equation underscores the need for balancing stock levels with customer demand. An effective OSA strategy doesn’t just prevent stockouts; it ensures a seamless shopping experience, builds customer loyalty, and maximizes sales potential.
OSA refers to the availability of products on the shelf that are ready for purchase when customers expect them. While tied to inventory management, it also considers visibility and accessibility, ensuring customers don’t leave stores empty-handed. It is a cornerstone of operational efficiency, bridging the gap between demand and supply.
OSA is more than just inventory management—it ensures products are visible, accessible, and available when customers need them. However, availability can be misleading if not measured correctly. This is where the distinction between OSA and the in-stock rate becomes crucial.
OSA vs. In-Stock: Understanding the Difference
While on-shelf availability (OSA) and in-stock rate are often used interchangeably, they measure different aspects of product availability.
- In-Stock Rate: This metric tracks whether a product is physically present in the store, including storage areas like the backroom. A high in-stock rate means the product is somewhere in the store but does not guarantee it’s available for purchase.
- On-Shelf Availability (OSA): OSA measures whether the product is actually on the shelf when a customer wants to buy it. Even if a product is in stock, delays in replenishment, misplaced inventory, or stockouts at the shelf level can lower OSA.
Why OSA Matters More for Sales
A product sitting in the backroom doesn’t generate revenue until it reaches the shelf. Low OSA leads to lost sales, dissatisfied customers, and potential brand switching. To ensure high OSA, retailers must focus on shelf-level replenishment, stock accuracy, and demand forecasting.
Ensuring products are in stock is only half the battle—what truly drives sales is having them on the shelf, ready for purchase. When OSA is low, the consequences go beyond just lost revenue; they directly impact customer trust and long-term loyalty.
Why is OSA Crucial for Sales Growth and Customer Satisfaction?
Studies indicate that customers are highly likely to switch brands or retailers when faced with stockouts, leading to significant revenue loss and reduced loyalty. For example, a report by IHL Group highlights that retailers lose over $1 trillion annually due to stockouts and overstocks, emphasizing the importance of OSA.
This highlights how crucial OSA is—not just for immediate sales but for fostering loyalty. Implementing the on-shelf availability formula can help retailers proactively prevent stockouts and keep their shelves ready for the next wave of shoppers.
The Impact of OSA on Brand Image and Market Share
For FMCG brands, low OSA directly impacts their reputation. Any customer would get frustrated if they walked into a store multiple times only to find their preferred product missing. Poor OSA creates a similar impression, pushing customers toward competitors. Conversely, retailers prioritizing OSA solidify their position as reliable choices, securing market share and customer trust.
