Sell-through rates measure how many copies are sold by retailers after stocking them on shelves, typically expressed as a percentage. For instance, if 100 books were shipped out and those retailers sold 80 back, then that sell-through rate is 80 percent.
Sell-through is a term in the book and publishing industry used to describe the number of units of an individual book sold directly by retailers to customers instead of being returned to publishers for returns. This metric serves both publishers and retailers in measuring its success.
Additionally, sell-through measures customer demand for books by measuring customer purchases as soon as they become available; an increased sell-through rate indicates strong customer interest, while an insufficient stock level could mean no one buying them. A low sell-through rate might signal either a lack of interest from readers or scarce copies being held by retailers to meet this need.
Publishers use sell-through data to determine print runs for other book editions. The publisher will likely take a risk and print more copies than before if the book has an excellent sell-through rate. If there is a low sell-through, the publisher can print fewer copies or change how they market and promote the book.
Sell-through is critical in the book publishing industry and forms the key success indicator of a book. A poor book sale means that the publisher may not reap any money from the deal and will likely put their money into future books from the author or in that book genre. Sell-through is also critical for authors as it could affect their book deals in the future. A new book deal may be complicated for an author when their prior books have yet to sell well. Today’s marketplace is competitive, and publishers and authors must focus on sell-through to succeed.
