What is Sell-In / Sell-Out?

Sell-In and Sell-Out

Definition

Sell-in refers to the volume of product sold FROM the supplier TO the retailer (what is placed in their warehouse or DC). Sell-out refers to the volume sold FROM the retailer TO the end consumer (what is scanned at the till). The gap between sell-in and sell-out represents stock held in the retail supply chain.

Examples of Sell-In / Sell-Out in FMCG

  • Sell-in spike before Christmas as retailers build stock
  • Sell-out data from EPOS (electronic point of sale) showing actual consumer takeaway
  • Promotional sell-in higher than sell-out creating a stock overhang after promotion ends

Sell-In / Sell-Out in the FMCG Industry

Monitoring sell-in vs. sell-out is critical for demand planning and commercial management. A persistent gap between sell-in and sell-out (sell-in > sell-out) means stock is building in the retailer's supply chain, which eventually leads to returns, promotions to clear stock, or de-listing. FMCG businesses increasingly use EPOS/sell-out data to manage this.
