Lyrics

[Verse 1]
When the numbers start to whisper secrets in the night
Statistical anomalies hiding from plain sight
We need more than just a snapshot, need the history to show
Baseline patterns tell the story of the fraudulent flow

[Chorus]
Benford's Law with chi-square testing
First digits never lie
Vendor spend trends are investing
Fifty percent makes us cry
Expense ratios we're detecting
Industry norms as our guide
Revenue per transaction
Payroll creeping up the side

[Verse 2]
Leading digits follow nature, one appears the most
Benford's distribution catches when the books are ghost
Chi-square test will prove the pattern, fraudsters don't obey
Mathematical laws of nature give their crimes away

[Chorus]
Benford's Law with chi-square testing
First digits never lie
Vendor spend trends are investing
Fifty percent makes us cry
Expense ratios we're detecting
Industry norms as our guide
Revenue per transaction
Payroll creeping up the side

[Verse 3]
Vendors spending fifty percent more than last year's take
Without a purchase order, that's a red flag we can't fake
Expense categories climbing way above the industry line
Average transaction values showing a declining sign

[Bridge]
AR lapping signals dancing
Customer balance rotation
Payroll as percentage rising
Revenue manipulation
Data history is the foundation
Baselines show the deviation

[Chorus]
Benford's Law with chi-square testing
First digits never lie
Vendor spend trends are investing
Fifty percent makes us cry
Expense ratios we're detecting
Industry norms as our guide
Revenue per transaction
Payroll creeping up the side

[Outro]
Six anomalies detecting
Tier two controls protecting
History-based reflecting
Financial fraud rejecting
