What is merchandising? – Definition and explanation

Definition and Mathematical Models Used in Merchandising

Merchandising is a set of activities and strategies that ensure a product is available in the right place, at the right time, at the right price, and in the right quantity, with the goal of maximizing sales and profit. This concept covers everything from product shelf presentation to sales performance analytics and inventory management.


Useful Formulas and Models for Merchandising Analytics

Merchandising analytics often relies on economic and statistical formulas to optimize performance:

1. Sales-to-Shelf Index (SSI)

SSI = (Total product sales / Number of shelf meters occupied by the product) × 100

2. Volume Sensitivity Index (ISVOL)

ISVOL = Total sales (in units or kg) / Total shelf size (m)

3. Gross Margin Sensitivity Index (ISMB)

ISMB = Gross margin / Linear shelf space

These metrics help managers compare the efficiency of different product categories and optimize shelf placement.


What Is Merchandising?

Merchandising is an operational discipline that acts as a bridge between marketing strategy and in-store sales execution. It is a set of activities that ensure products:

✔ are visible and accessible to customers
✔ have correct and clearly displayed prices
✔ are properly rotated (to avoid obsolete or expired stock)
✔ are strategically positioned within the store

In other words, marketing brings the consumer to the shelf, but merchandising ensures that the customer actually puts the product into the basket.

Merchandising includes everything from assortment planning and planograms to inventory control and product presentation. With the right tactics, merchandising influences how consumers perceive a product and increases the likelihood that they will choose it.


Why Merchandising Is Important for Sales

Merchandising is not just arranging products on a shelf — it is the physical execution of the sales strategy. Effective merchandising:

✅ increases product sales
✅ improves brand perception
✅ reduces out-of-stock situations
✅ enables better control of inventory and promotional pricing
✅ increases profit per square meter of retail space


Five Core Elements of Merchandising

For merchandising to deliver results, it must focus on five key aspects:

  1. Planogram compliance – accurate product positioning

  2. Pricing and promotional communication – clear and correct price display

  3. Stock management – timely replenishment

  4. Secondary placements (POS / POP materials) – impulse purchase opportunities

  5. Visual presentation and shelf cleanliness – neat and attractive display


Merchandising by Sales Channel

Merchandising strategies vary depending on the sales channel:

1. Modern Trade (Key Accounts / Hypermarkets)

This channel relies on precise logistics, digital price tracking, and strong competition for shelf visibility.

2. Traditional Trade (TT)

In smaller stores, the human factor and relationships with store staff often determine where and how products are positioned.

3. Specialized Channels

Here, the focus is on aesthetics and branded customer experience, including promotional materials and product tastings.


Types of Merchandising

Merchandising includes several disciplines:

🔹 Product Merchandising – micro-level product display optimization
🔹 Retail Merchandising – optimization of the entire store
🔹 Visual Merchandising – visual stimulation to drive purchases
🔹 Digital / E-merchandising – online product presentation
🔹 Omnichannel Merchandising – integration of offline and online experiences


Merchandising in Serbia and Belgrade

In Serbia, merchandising is a key discipline in FMCG and retail. The specific characteristics of the market — such as different store formats and consumer habits — require strategies tailored to the local context, particularly in major urban centers like Belgrade.

Many agencies in Serbia provide nationwide merchandising services, covering Belgrade as well as other major cities.


Conclusion

Merchandising is a discipline that connects brand strategy with actual in-store sales performance. Without proper execution, even the best marketing campaign remains underutilized. If you want your products to be visible, available, and profitable, understanding and implementing effective merchandising practices is essential.
