How BILL Spend & Expense’s scores are calculated
The full audit trail, recomputed from the verdict data at build time through the same code that produced the leaderboard: verdict × quality × story weight per cell, cells sum to dimension scores, dimensions blend into the PA Score. Every number on the product page is reproducible from this page alone; for why the formula looks like this, see the methodology.
verdict factors: full ×1.0 · partial ×0.6 · disputed ×0.3 · none ×0.0 · n/a excluded from both sides · cell points = weight × quality × factor · cell max = weight × 10
PA Score24/100
Agent-ready 41.4 × 0.30 = 12.42
API quality 10.0 × 0.20 = 2.00
Openness 22.8 × 0.20 = 4.56
Built-in AI 16.7 × 0.15 = 2.50
Automation 15.8 × 0.15 = 2.37
(12.42 + 2.00 + 4.56 + 2.50 + 2.37) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 23.86 ÷ 1.00 = 23.9
Scores are stored to 1 decimal; the product page’s pills round to whole numbers for display. Each dimension below shows the stories, verdicts, and cited evidence behind its number.
