I need a single Excel or Google Sheets file that brings every routine office task under one roof. The workbook must let me record daily attendance, convert that data automatically into salary figures, assign and track staff tasks, follow stock levels in real time, monitor outstanding credits, and log each purchase. I also rely on Tally, so the sheet should exchange data with it smoothly—either through a direct import/export format or a lightweight script that keeps key ledgers in sync. Functionally, I expect: • Daily attendance logs that flow into monthly salary calculations without extra manual steps. • Task allocation tables where I can drop new jobs in and instantly see current workloads. • Stock and purchase sections tied together so incoming items raise stock and outgoing items reduce it, all visible on a simple dashboard. • An outstanding-credit tracker that updates automatically when payments land. • A tested link to Tally (CSV mapping or Google Apps Script/Power Query) so figures match on both sides. Please build with clear labels, locked formulas where necessary, and enough sample data to demonstrate everything works.
