Sell-Through
Sell-through is the percentage of a product that has been sold by a retailer compared to the total quantity they received or stocked. It is calculated by dividing units sold by units received and expressing that as a percentage. A sell-through rate of 80 percent or above is generally considered strong in beauty retail; below 60 percent raises flags.
Why it matters
Sell-through is the most important number in your retail relationship - more important than your pitch deck, your press coverage, or how much the buyer personally loves the product. It is the number that determines whether you survive a range review. Buyers have targets, and those targets are tied directly to whether their category is performing. If your sell-through consistently underperforms the category average, you will be delisted regardless of your brand story.
The brands that stay on shelf long-term treat sell-through as a live metric, not a retrospective report. They know their numbers week by week, they understand what drives spikes and dips, and they actively support their retail partners with marketing activity that converts browsers into buyers. If your sell-through is lagging, the answer is rarely more SKUs - it is usually a combination of better in-store presence, more consumer awareness, and clearer on-shelf education about what the product does and why someone should pick it up.
Key points
Sell-through below 60 percent in a major retailer is a delisting risk regardless of brand performance elsewhere
Track sell-through weekly, not just at range review - by the time a review arrives, you have had months to course-correct
In-store staff training directly improves sell-through because a confident recommendation converts far better than packaging alone
Seasonal promotions and in-store events can rescue sell-through in a struggling door before it becomes a range review problem
Share sell-through data proactively with your buyer - do not wait to be asked
