How a $10.00-per-box overcharge remained undetected for 3 years because it was buried in 90% of correctly billed data.
Total Bottom-Line Recovery

“Any cost recovered is directly equivalent to profit earned, no additional revenue required.”
The client, a mid-size e-commerce operation generating ~$1M/month in revenue, sold consumer goods across five channels: Amazon (39%), Walmart (20%), eBay (15%), Shopify (16%), and Distributors (10%). Products were packed in master boxes of 6 inner units each, at an average selling price of $50 per box. Total fulfillment volume was approximately 20,000 boxes per month across all channels.
Why Blended Aggregate Invoice Review Failed
The error only affected the Distributor channel (10% of volume). Because the other 90% of marketplace shipments were billed correctly, the $25,000 monthly overcharge was masked by the $1M in total monthly revenue. Without distributor channel segmentation, the leak was mathematically invisible. Standard accounting missed it. Forensic auditing caught it.
Financial reviews were conducted at an aggregate level, with no third-party warehouse billing integrity checks in place. Management believed shrinking margins were due to rising logistics and marketplace fees. No prior review had applied Order Management System (OMS) cross-referencing or channel-level cost analysis to warehouse invoices.
Only the Distributor channel included promotional brochures (10 per box), which triggered the unauthorized handling surcharge.
The “Invisible” Leak
Warehouse billed $1.00/brochure for 10 brochures on Distributor boxes, an unauthorized $10.00 surcharge per unit. This touched only 10% of volume, making it invisible in blended aggregate invoices.
Forensic Resolution
We isolated the 10% Distributor volume from the 90% Marketplace volume to identify the specific channel where the contract was being violated.

The “Invisible” Leak
Approximately 310 canceled or refunded orders per month were still being billed as 'fulfilled' by the 3PL. Standard reconciliation never checked order status.
Forensic Resolution
Cross-referenced Warehouse Invoices against the Client's OMS (Order Management System) to identify $122,760 in uncredited fees.

The “Invisible” Leak
Duplicate line items ($920/mo), incorrect box counts ($640/mo), and transposed figures ($480/mo) occurring systematically over 36 months.
Forensic Resolution
Conducted an Independent Recalculation of every line item at contracted rates, recovering an additional $73,440 missed by internal AP.

Review of invoice documents, service agreements, dispatch records, and OMS data cross-referenced by channel, shipment type, and fulfillment instruction.
Independent recalculation of monthly charges by channel at contracted rates. Direct confirmation of refund and cancellation statuses from the client's OMS.
We reperformed the warehouse's own reconciliation process, segmented by channel, to find exactly where their internal controls failed to distinguish distributor from marketplace shipments.
We utilized month-over-month variance analysis on per-box charge rates, segmented by channel, to isolate anomalies that were completely invisible in blended aggregate reviews.
We cross-referenced warehouse billing data against the client's internal Order Management System (OMS) to confirm the actual status of every box, identifying 310 canceled orders billed as fulfilled each month.

“Any cost recovered is directly equivalent to profit earned, no additional revenue required.”
Acgile improved this client's effective margin without them having to sell a single extra product or spend a dollar more on marketing. The $919,336 recovery was achieved through channel-level billing scrutiny alone.
Standard reconciliation matches invoice totals to vendor statements at an aggregate level. When overcharges affect only one sales channel (e.g., 10% of volume), they become invisible in blended totals. Channel-level segmentation is required to isolate discrepancies.
It is the practice of segmenting third-party warehouse invoices by individual sales channel (Amazon, Walmart, eBay, Shopify, Distributors) rather than reviewing blended totals. This reveals cost variances that only affect specific fulfillment paths.
Any cost recovered is directly equivalent to profit earned because it reduces COGS without requiring new sales, marketing spend, or operational effort. The $919,336 recovery improved the client's effective margin without a single change to pricing, product, or sales strategy.
If your third-party warehouse bills are reconciled in aggregate, you could be losing thousands every month without knowing it. Let Acgile's forensic audit team find out.
