A Practical Guide to Using Formulas for Freight Invoice Audits and Anomaly Detection
The Hidden Drain: Inefficient Logistics Patterns
In global logistics, consistent overcharges often hide in plain sight, disguised as routine shipments. Manual invoice review misses recurring, costly patterns across routes, carriers, and service levels. The CNFANS Spreadsheet methodology
Core Analytical Formulas for Pattern Detection
1. Benchmark Rate vs. Actual Charge Variance
Flag invoices where actual cost exceeds agreed or benchmark rates.
=IF([@[Actual Cost]] [@[Benchmark Rate]], "Overcharge", "OK")Combine with conditional formatting to instantly highlight all overcharges in red.
2. Cost per Unit Inefficiency (e.g., Cost/KG, Cost/CBM)
Identify shipments with abnormally high unit costs, signaling inefficient consolidation or wrong weight brackets.
=[@[Total Charge]] / [@[Weight (KG)]]Use =AVERAGEIFS()
3. Detouring Pattern Analysis
Pinpoint illogical routing that increases cost and transit time.
=IF([@[Actual Route]] < [@[Optimal Route]], "Detour", "Direct")Pivot this data to see which lanes or carriers have the highest detour frequency.
4. Accessorial Charge Frequency
Quantify how often and why extra fees are applied.
=COUNTIFS(ChargeTable[Shipment ID], [@[Shipment ID]], ChargeTable[Charge Type], "Accessorial")Cross-reference with =UNIQUE()
