My Bestselling Fragrance Keeps Running Out — Should I Hold More Fragrance Oil Inventory than I Hold for Slower-Selling Candle Scents?

Why bestsellers run out

Picture a small range where one scent sells 120 candles a month and the slowest sells 10. If both are bought as two 100 g bottles at a time, the slow scent's 200 g lasts 38 days. The bestseller's 200 g lasts 3.1 days. If the habit is to reorder when the last bottle is empty, the bestseller is out of stock for the whole order-to-delivery time, every cycle. With an example 7-day wait, that is about 3.0 stock-outs a month and roughly 83 candles a month not made — about 69% of its potential sales.

There are four common causes, and a bestseller usually suffers from more than one: the order size is too small for its speed; the reorder trigger is too late (empty, instead of a level that covers the wait); the lead time is longer than assumed, especially before festivals; and demand spikes — a gifting order or a festive week — land on the scent people already buy most. A fifth cause is outside your control: the pack you rely on can itself go out of stock at the supplier. The fixes below address each in turn.

Stock by speed, scent by scent

The answer to the title question is visible in one table. Each scent's stock is built from the same three rules — reorder point, safety stock and an order pack matched to its speed — with the same example inputs: a 7-day lead time and a busiest week running at 1.5× the average rate. The only thing that changes is how fast each scent sells.

The bestseller holds about 724 g on average, the tail scent about 69 g — roughly 11 times as much oil. But look at the last column: every tier carries well under half a month of stock. That is the right shape. A bestseller should turn over at least as fast as any other scent; the extra grams are there to cover its much larger use during the wait for delivery, not to sit longer. If your bestseller has more months of cover than your slow scents, you have overcorrected; if it has far fewer grams in its safety buffer, you will keep running out.

Notice also how the order pack follows speed. The bestseller orders 1 kg, the second seller and the middle scent 500 g, and the tail a single 100 g. For Lemongrass and Lime, the 500 g and 1 kg are both ₹5.20 a gram, 11.9% below the 100 g. For Vetiver, the 1 kg is out of stock on the pull date, so the 500 g (₹5.80 a gram) is its production pack. For the tail, 100 g is already the lowest rate most oils offer, and a bigger pack would only add months of stock.

What a stock-out costs

Start with the value of one candle. At an illustrative selling price of ₹499 (a price used across this series, not a recommendation), a 200 g Lemongrass and Lime candle has materials of ₹270.12: ₹186.92 for wax, wick and jar, plus ₹83.20 of oil at the kilo rate. That leaves ₹228.88 of materials contribution per candle — before labour, packaging, payment fees and shipping, which you would deduct with your own figures. At 120 candles a month, the scent sells about 4 candles a day.

The comparison is not close. A single day out of stock costs more than holding a spare kilo for 9 months. Even if half your customers switch to another scent when the bestseller is missing, the loss per day is still ₹457.77. And the table leaves out costs that are harder to count: a stockist who stops reordering because you could not fill a repeat order, a gifting client who goes elsewhere, a marketplace listing that loses ranking while it shows "out of stock".

The scents in the example

The bestseller, a second seller whose biggest pack is out of stock, and a mid-range scent that shows why flat pricing changes the pack decision.

Protecting the bestseller

A reorder point only works if someone checks it. For a range of ten or twenty scents, a weekly stock count against a simple sheet — scent, reorder point, current grams — takes minutes and catches almost every problem before it becomes a stock-out.

One last check: make sure the bestseller really is running out because of demand. If it runs out because a batch failed and had to be re-poured, or because oil went into testing, the fix is in production, not purchasing. And if its sales are rising month on month, the reorder point you set today will be too low in eight weeks.
