Peak-season parcel expense is not simply normal volume multiplied by the contracted base rate. Demand surcharges, additional handling, oversized packages, residential delivery, delivery-area charges, fuel and service changes can alter the effective cost per shipment.
Model the shipment profile
Use last year's weekly shipment file, not a monthly average. Segment packages by carrier, service, zone, weight, dimensions, residential status and surcharge type. Overlay the current carrier calendars and fee tables on the weeks in which the business expects volume to rise.
Finance should model cost per order and cost per package under base, expected and stress-volume assumptions. Logistics should identify which fees are driven by contract terms and which can be reduced operationally.
Focus on avoidable triggers
Packaging dimensions, label compliance, address quality, service selection and split shipments can create fees that a headline discount does not solve. Establish packaging thresholds, validate addresses before tender and monitor high-cost exceptions daily during the peak window.
Blackspire's Shipping & Delivery Solutions review examines invoice data and operational triggers together so leadership can see whether leakage belongs in the contract, warehouse or ordering process.
Reconcile after peak
Compare forecast to actual by surcharge type and carrier. Investigate material variance, pursue eligible billing adjustments and retain the findings for the next negotiation. Peak expense should become a measured operating category, not an annual surprise.
