List each budget line with its budget and actual spend; variance, percent spent and a per-line flag (OK / Watch / OVER) compute automatically. On Settings you set the grant dates and the FX rate, so the Dashboard can show both the grant currency and your local-currency equivalent.
The Dashboard is the early-warning system: burn rate vs period elapsed, a plain 'Ahead / On pace / Behind' pace verdict, and a projected final spend with the over/under against budget. You see a problem while there's still time to fix it — not in the final report.
