Used Book Stock Ledger2026 аналитика приложений для 6 октября

Used Book Stock Ledger is an offline management tool designed for secondhand bookstores, used book stalls, book fair sellers, and personal book resale. Record each book's title, author, publisher, ISBN, condition, purchase price, list price, quantity in stock, and shelf location. When a book is sold, you can quickly deduct inventory and review profit and out-of-stock status. No account registration is required. The app does not connect online or upload data. All inventory, price, stocktaking, and sales records are stored locally on your device, making it suitable for booksellers who want a one-time purchase tool instead of spreadsheets, paper ledgers, or generic bookkeeping apps. Key features: - Book inventory files: save title, author, ISBN, publisher, condition, location, quantity, and notes. - Purchase and sale pricing: record purchase price, list price, and sold price, then calculate item and batch profit. - Sales stock deduction: log sold quantity, date, and channel while inventory is reduced automatically. - Stocktaking and shortage lists: filter by shelf, category, or condition to organize low-stock and sold-out books. - Local export: export inventory tables, sales records, and stocktaking results offline for backup or printing.
