I need a single, cohesive sales-tracking dashboard recreated for three environments—Apple Numbers, Google Sheets, and Microsoft Excel. The core workbook must include a sales ledger, individual customer account pages that pull their data automatically, and a summary dashboard that visualises key metrics through charts, tables, and graphs. Scope of the dashboard • Metrics: total sales, sales by product, and sales by region, all updating in real time from the ledger. • Filters: quick drop-downs or slicers for date, product, and customer so I can isolate any segment instantly. • Visuals: clean, business-ready layouts that render consistently across the three platforms, using native charting tools (e.g., PivotCharts in Excel, Charts in Numbers, built-in charts in Google Sheets). • Automation: formulas or pivot logic that eliminates manual entry; adding a new row in the ledger should ripple through every view. • Extra sheets: an opening “Read Me” with a brief usage guide and an accounts receivable / payable snapshot derived from the same data. Deliverables 1. Apple Numbers file (.numbers) with fully working dashboard, ledger, and customer pages. 2. Microsoft Excel workbook (.xlsx) using only native functions and Power Pivot or PivotTables where appropriate. 3. Google Sheets link with identical structure and functionality, ready for cloud collaboration. 4. Short setup guide (PDF or embedded note) explaining how to refresh data, extend product lists, and customise colour themes. Acceptance criteria – All three versions return identical figures when fed the same sample data. – Filters respond instantly without breaking formulas. – Visuals remain legible when printed on A4/Letter. – No external add-ins or paid scripts required. If you have experience building cross-platform financial dashboards and can hand over polished, plug-and-play files, I’d love to see examples of similar work and get started right away.
