Red Flag: Sales/revenue is reported, but cash deposits are lower than expected.
Check:
Bank statements vs. reported revenue
Are all sales actually deposited?
Cash-heavy businesses are especially vulnerable
Red Flag: Expenses seem too high or grow suddenly without a matching business reason.
Check:
Look for large or recurring payments to unknown vendors
Personal items marked as “business expenses” (e.g., groceries, travel)
Split transactions (e.g., two $499 charges instead of one $998 to stay under approval limits)
Red Flag: Payments to vendors or people who don’t exist.
Check:
Run a list of all vendors and employees
Cross-check names, addresses, tax IDs
Look for duplicate or similar names
Red Flag: Random spikes in spending, or consistent round numbers (e.g., $1,000, $5,000 repeatedly).
Check:
Compare monthly or quarterly statements
Graph expenses over time—spikes can reveal manipulation
Sudden increases in things like “office supplies” or “consulting fees” may be a cover
Red Flag: Missing documentation for expenses or reimbursements.
Check:
Ask for receipts to match line items
No receipt? No reimbursement.
Scan for “Miscellaneous” or vague categories—this is often where shady stuff hides
Red Flag: Gross margin drops with no reason (suggests either theft or cost inflation).
Formula:
text
CopyEdit
Gross Margin = (Revenue - Cost of Goods Sold) / Revenue
Check:
Has the cost of goods spiked?
Is inventory disappearing (without sales)?
Inventory shrinkage = classic theft signal
Red Flag: One person writes checks, manages receipts, handles payroll, AND does the books.
Check:
Segregation of duties is key. Even small orgs should divide financial roles.
Always have someone else review or audit quarterly.
Excel/Google Sheets → Track trends, highlight large or duplicate payments
Bank Reconciliation → Compare books vs. real cash flow
Audit Logs (for software) → See who’s entering or editing records
If something feels off—dig deeper. A paper trail always exists, especially with digital banking.
