How Retailers Can Track Fast-Moving and Slow-Moving Products During Diwali

Customers are quite excited about Diwali shopping, and why not when it brings so many colours and good vibes? During Diwali, products that often sell more slowly usually sell faster. Some products may become in high demand, while some items retailers stocked in anticipation of festive demand may barely move. For businesses managing multiple product categories, keeping track of changes in shopping trends is crucial. Without regular checks, popular products can run out just as demand peaks, leaving other shelves crowded with unsold stock.

Let's consider a retailer who is selling decorative lights, gift boxes, diyas, and home decor items. While decorative lights may sell quickly around Diwali, not all gifting boxes may get sold. Some may even remain untouched. Ordering more of everything would tie up money unnecessarily, but ignoring stock movement could mean missing sales of popular products.

So, the solution here is to monitor how each product sells, compare it with the available quantity, and adjust purchasing decisions accordingly. Retailers can use sales records and inventory reports to understand what is moving, what is sitting on the shelf, and what action each product needs. This helps them replenish stock on time without overbuying.

Understand fast-moving, slow-moving, and non-moving stock.

Before checking inventory movement reports, retailers must understand the difference between fast-moving and slow-moving inventory and non-moving products.

• Fast-moving products in retail include items that sell frequently or in high quantities. During Diwali, these might include popular decorative lights, sweets, candles, or commonly purchased gift packs. Such products may require frequent replenishment, especially when suppliers need several days to deliver new stock.

• Slow-moving stock management consists of products that sell less frequently or take longer to clear than expected. A particular colour of decorative item, a premium gift hamper, or an expensive home accessory may fall into this category. Slow movement does not automatically mean a product is a poor choice. Its price, target customer, and normal sales cycle also matter. Slow-moving stock management is thus equally essential.

• Non-moving stock refers to items that have recorded little or no movement during a defined period. These could include outdated designs, products with limited appeal, or goods purchased in quantities that exceed demand. Some products are naturally seasonal, so a lack of sales outside their selling period does not necessarily mean excess stock.

Retailers should classify products using their own sales history and current conditions rather than relying on a single rule for every item.

Review these categories regularly during Diwali. A product that was slow-moving two weeks earlier may start selling quickly as the festival approaches. Equally, an item that sold well at the beginning of the season may no longer need an additional reorder level.

Use product-wise sales and inventory reports

Inventory reports with sales totals can tell you how much the business has sold. However, they may not reveal which products are responsible for that performance. Product-wise reports provide a more useful view by showing the quantities sold, stock remaining, and movement over a selected period.

Start by reviewing sales for individual products. Compare the number of units sold over the past few days or weeks with the stock currently available. A product with consistently strong sales and limited stock may need replenishment, while one with a large closing balance and few sales may need closer attention.

Next, compare different periods. Sales of festive goods often follow a pattern: demand may build gradually, peak close to Diwali, and drop after the festival. Comparing the current week with the previous week can help identify changes. Also, the same period from the previous year may provide additional context if the business has reliable records.

Calculate a simple inventory movement measure

Retailers do not always need complex calculations to understand product movement. A basic measure is to compare the quantity sold during a specific period with the average stock held over that period. This helps show whether a product is selling quickly relative to the inventory available.

One simple measure is the inventory turnover ratio:

Inventory turnover ratio = Cost of goods sold ÷ Average inventory value

Average inventory value is generally calculated by adding the opening and closing inventory values and dividing the result by two. For a more detailed analysis, businesses can use more frequent inventory values when stock levels change significantly during the period.

Suppose a retailer's cost of goods sold for a selected period is ₹1,20,000. The average inventory value during that period is ₹40,000.

Inventory turnover = ₹1,20,000 ÷ ₹40,000 = 3 times

This means the cost of goods sold during the period was three times the average inventory value. It does not mean every product sold three times; the calculation reflects the inventory as a whole or the particular category being analysed.

Retailers can also use a simpler unit-based measure to monitor individual products:

Units sold during the period ÷ Average units held during the period

For example, if a retailer sold 90 units of a decorative item while holding an average of 30 units, the unit-based movement measure would be 3 for that period. Use consistent periods when comparing products. A turnover figure for seven days should not be compared directly with one calculated for an entire month. Also, a high stock turnover ratio is not always better: stock may be selling quickly because the business is holding too little and repeatedly missing potential sales.

For Diwali planning, use the calculation as a signal alongside sales trends, current stock, supplier lead times, and expected demand. The aim is to understand whether inventory is moving at a reasonable pace, not to chase a high number without considering the business context.

Prioritise fast-moving products for replenishment

Fast-moving products deserve close attention during the festive rush because a stockout can mean losing a sale at a time when customers are ready to buy. However, ordering more stock simply because an item is popular can also create problems if demand is about to fall.

Start by checking the current stock balance, pending customer orders, and incoming purchase orders. Then estimate how many units are likely to sell before the next delivery arrives. If the available quantity is unlikely to cover that demand, contact the supplier early rather than waiting until the shelf is nearly empty.

Supplier lead time is important. A product that takes two days to arrive may be easier to replenish at short notice than one sourced from a distant supplier with a delivery time of ten days. Account for these differences when deciding which products need earlier attention. Prioritise replenishment using a few practical checks:

• Sales pace: How many units are selling each day or week?
• Stock available: How many saleable units remain?
• Incoming stock: Are confirmed deliveries already on the way?
• Supplier lead time: How long will a new order take to arrive?
• Remaining festive demand: How much time is left in the selling period?

For example, a retailer selling 15 units of a particular decorative light daily with only 30 units remaining may need to act quickly if the supplier requires five days to deliver. But if Diwali is only two days away and demand is expected to fall immediately afterwards, a large order may not be sensible.

The decision should balance the risk of running out against the risk of being left with excess stock. Replenishment is most effective when it responds to both the current sales pace and the time remaining to sell the goods.

Investigate slow-moving products

Slow-moving products should not automatically be marked down or removed from the catalogue. First, find out why sales are lower than expected. The reason will determine whether the retailer should adjust the price, change the display, transfer stock, or simply wait for the right buying period.

Begin by comparing the product's sales with the quantity held. Check whether the item has received enough customer attention, whether its price is competitive for its market, and whether customers are choosing similar products instead. Feedback from sales staff can help explain what the numbers alone cannot.

Stock condition also matters. Packaging may be damaged, a design may have become less appealing, or an item may no longer match current customer preferences. If the problem is presentation, improving the display may help. If the issue is weak demand at the current price, a carefully calculated offer could be worth considering.

Check whether the product is genuinely slow-moving or simply has a different selling cycle. Expensive décor pieces, premium gifts, and specialised products may sell less often but still contribute useful profit. Judging them only by the number of units sold can lead to unnecessary discounting.

Retailers should also consider how much cash is tied up in the stock and whether the product is likely to sell later. A non-seasonal item may be worth holding, while highly seasonal goods may need a decision before festive demand disappears.

Plan promotions and stock transfers carefully

Once retailers identify products that need attention, they can choose an appropriate response. Promotions and stock transfers can help improve inventory movement, but retailers should plan them rather than use them as automatic fixes. A targeted promotion may help clear slow-moving festive stock. For instance, a retailer could offer a bundle of candles and decorative accessories instead of discounting every product in the store. The offer should account for the cost of all included items and leave an acceptable margin.

Avoid reducing prices on fast-moving products without a clear reason. If customers are already buying them at full price, a discount could simply reduce the profit earned on sales that would have happened anyway. Stock transfers can be useful when a business operates multiple shops or warehouses. 

One location may have excess stock of a product while another is running low. Moving available goods between locations could meet demand without placing another supplier order.

Before transferring stock, check the quantities available at both locations, the cost and time required to move the goods, and whether the receiving location is likely to sell them. 

Record the transfer properly so that inventory balances remain accurate. Choose promotions or transfers based on the reason stock is moving slowly. A product may need better visibility, a different price, a change in location, or no immediate action at all. For these purposes, inventory management software can be very helpful.

Review product movement after Diwali

Product movement often changes sharply once Diwali ends. Demand for certain decorative items may fall, while products with regular year-round demand continue selling. Reviewing stock after the festival helps retailers decide what to retain, replenish, or clear. Start by comparing actual sales with the quantities purchased for the season. Identify products that sold faster than expected, items that met expectations, and those left in excess.

Review the cost and quantity of the remaining inventory. A large number of low-value items may present a different problem from a few expensive products that tie up substantial working capital. Check the condition of unsold goods and whether they can be stored safely for a future season. Use the findings to improve the next festive plan.

Keep a record of the products that performed well and the dates when their sales accelerated or slowed. This information can guide future forecasts, but you should adjust it for changes in prices, customer preferences, and market conditions.

The goal is not to eliminate every unsold item or keep every shelf full. It is to ensure stock management that matches demand while limiting the money tied up in products unlikely to sell. Regular product movement reviews help retailers make those decisions using evidence rather than guesswork.
