Authors and publishers struggle to access accurate sales data for published books

Authors, publishers, and researchers lack transparent access to real-time or historical sales figures for published books, forcing them to rely on incomplete industry reports, publisher estimates, or guesswork. This information gap makes it impossible to assess a book's market performance, inform marketing decisions, or understand audience reach. Current solutions like Nielsen BookScan have limited coverage and are expensive or inaccessible to independent authors and smaller publishers.
