● Case File: Open · Occupational Fraud
45 years of forensic bookkeeping experience, condensed into 36 real methods employees use to quietly drain a business — and the exact red flags that expose every one of them.
Numbers don’t lie. People do. — Charlie Montgomery


Why This Book
This isn’t theory from a textbook. Every case file comes from Charlie Montgomery’s own consulting work — the exact patterns she found while cleaning up years of tangled books for small business owners who trusted the wrong person.
8 case files on bogus vendors, duplicate checks, and look-alike company names.
12 case files on ghost employees, changed payroll buckets, and colluded raises.
9 case files on personal charges, missing deposits, and vanishing petty cash.
Each of the 36 entries explains exactly how the scheme works, step by step.
Pull the matching report and check your own transactions against the pattern.
Learn the specific red flag that gives each scheme away, even when it’s hidden.
Apply the simple control changes that make the scheme impossible to repeat.



The Investigator
A full-charge bookkeeper and business advisor with more than 45 years of experience. Her consulting business was built almost entirely on referrals from CPAs who couldn’t file tax returns for certain clients because their bookkeeping systems were too inaccurate to trust.

On The Record
Four real bookkeepers. Real prison sentences. Millions taken first.

Forged 118 checks over 3+ years as a non-profit bookkeeper. Sentenced to 33 months.

Fraudulently drained her employer's accounts over 5 years while filing false tax returns.

Diverted vendor checks for 2 years, then vanished for 8 before being caught.
36 case files. One weak control is all it takes — know what to look for before it costs you.
