Define what is inside the estimate

A freight quote, a landed-cost estimate, and a return-handling scenario can include different cost boundaries. State the destination, period, currency, and treatment of shared costs before comparing totals. Keep fixed allocations separate from costs that genuinely change with one more shipment or order. An attractive unit cost can conceal a larger total commitment.

Avoid counting one loss twice

Use contribution rather than full revenue when a model asks for lost contribution. Do not add a refund to a returns model that already represents the same inventory loss, and do not add fees already included in a carrier quote. Test an uncertain assumption while keeping the others fixed. The difference between scenarios is a planning sensitivity, not a promise of achievable savings or an accounting determination.
