Sell-in is what a brand sells to its retailers or distributors; sell-out is what those retailers then sell to consumers. Sell-in shows up in the brand’s own orders and invoices, while sell-out happens one step later, at the retailer’s till or website, and usually sits in the retailer’s data.

Sell-in is the brand’s revenue: orders written, goods shipped, invoices raised. Sell-out happens later and one step removed, when a consumer actually buys the product in a store or on a retailer’s site.
A strong sell-in season followed by a weak sell-through is the classic wholesale trap. The brand books the revenue, the retailer is left holding stock, and the correction arrives the following season as smaller orders, discount demands, or a lost account.
Sell-through links the two: it is the share of units a retailer received that it has sold to consumers within a given period. High sell-in with low sell-through means stock is piling up at the retailer; high sell-through on modest sell-in usually means the product was under-bought.
Most brands see sell-in perfectly and sell-out poorly, because the data belongs to the retailer. Some partners share weekly reports, some share nothing, and formats rarely match.
Brands that do get sell-out data can reorder into demand, spot which doors are actually selling rather than merely buying, and plan the next season on consumer behaviour instead of on their own invoices.
