Not a template you fight with
| Feature | This system | A generic template |
|---|---|---|
| The formulas | Visible and editable. You can trace any number back to its source. | Often locked or protected so you can't see the working. |
| When it doesn't fit | Change it. The structure is yours once you download it. | Work around it, or start over. |
| Formats | Google Sheets and Excel, both included. No installation. | Usually one, often the one you don't use. |
| Who built it | An analyst who has had to defend a number to a CFO. | Frequently unclear. |
