Recover the Linehaul Margin Hiding in Your Box Catalog.
We conduct retrospective, invoice-level forensic audits to isolate packaging-driven dimensional penalties. Identify exactly where your fulfillment operation is overpaying UPS and FedEx—and permanently eliminate the waste.
From Theoretical Math to Verified Carrier Savings.
Our methodology replaces assumptions with forensic data. We ingest 12 months of historical carrier rate cards, accessorial charges, and dimensional weight penalties to build a factual baseline. We don't guess; we calculate the exact financial impact of suboptimal packaging geometry down to the carton level.
Historical Carrier Reconciliation.
Invoice-level analysis of DIM weight penalties vs. actual weight charges to quantify baseline exposure and identify high-frequency penalty zones.
Box Rationalization (SKU-to-Carton Profiling).
Algorithmic mapping of true 3D spatial SKU dimensions against current box catalog to isolate void space and propose optimized geometry sets.
Operational Friction (Implementable Constraints).
Validation of theoretical models against warehouse floor realities, ensuring proposed carton sizes fit racking, corrugate limits, and packing station workflows.
Gain-Share Validation (Contractual Counterfactuals).
Rerunning historical shipments through the optimized geometry model applying current carrier contracts to project verified, realizable savings.
The Anatomy of a Forensic Margin Audit.
We do not simply calculate ‘smaller boxes.’ We reconstruct your shipment history against spatial physics, warehouse operational constraints, and carrier rate cards.
Historical Baseline Ingestion.
We ingest up to 250,000 past outbound carrier manifests and your SKU master data, mapping spatial package density directly against your contractual carrier rate cards, custom DIM divisors, and minimum net billable charges (or standard carrier schedules where custom contracts are unprovided).
Constrained Spatial Simulation.
We map your product dimensions against an engineered carton library. The algorithm calculates 6-degree rotational freedom for rigid goods, applies a strict 0.5mm structural clearance buffer, and accounts for deformable soft goods to find the true minimum viable cube.
Carrier Rate & Tier-Cliff Logic.
Volume reductions only matter if they cross a carrier billing cliff. We run the optimized dimensions back through your specific FedEx/UPS rate matrix, accounting for minimum zone floors, residential surcharges, and fuel indices.
Operational Friction Deduction.
We subtract the realities of the warehouse floor from the gross savings. We deduct the unit-cost delta of procuring new corrugated cardboard, the cost of protective void-fill, and a baseline packer-error rate to deliver a purely implementable net margin recovery figure.
