Sell-through
The share of stock a channel partner has sold on to end customers, out of the stock it bought from the supplier in a period.
Sell-through is the share of stock that a channel partner, such as a distributor, dealer or retailer, has sold on to end customers during a period, out of the stock it bought from the supplier. It is usually shown as a percentage. A dealer that received 500 units in a quarter and sold 350 of them to customers has a sell-through of 70%.

How do you calculate sell-through?
Divide the units sold to end customers by the units available in the same period, then multiply by 100. Teams define “available” in one of two ways: units received during the period, or opening stock plus units received. Both work, but switching between them makes trends meaningless, so pick one and keep it. Dollar sell-through uses the same logic with values instead of units, which matters when a partner sells a mix of cheap and expensive products.
How is sell-through different from sell-in?
Sell-in is what the supplier ships to the partner. Sell-through is what the partner sells on. A supplier can grow sell-in for a quarter by pushing stock into the channel, but if sell-through does not follow, the partner is left holding inventory it cannot move. That stock tends to come back later as returns, price protection claims or heavy discounting. Comparing the two over several periods shows whether the channel is building real demand or filling warehouses.
Why do channel incentives use it?
An incentive paid on purchases rewards the order. One paid on sell-through rewards the sale to the end customer, which is the outcome most suppliers actually want. Rebates, spiffs and dealer points programs can all be tied to sell-through, or to the sell-out data behind it, so partners earn only when products leave their shelves. The cost is data: the supplier needs reliable reporting from partners, often point-of-sale or serial number records, and a way to check claims before paying them.
What should you watch?
Data quality comes first. Partner reports can be late, incomplete or formatted differently from one partner to the next, so agree the format, frequency and audit rights in the program terms. Timing is the second issue: sell-through lags shipments, so incentives based on it pay later, and partners need to know when they will be paid. Finally, read the number in context. A low rate can mean weak demand, but it can also reflect a new product, a seasonal build or a partner that stocks deep on purpose. Look at weeks of inventory on hand and the partner’s own history before changing its targets or tier.
