Centralized freight + landed-cost rules. Admin enters these once; the ERP automatically uses them at receiving, in inventory costing, and in profitability reporting. This is not a shipment entry page.
Master rules · power the whole system
At Receiving, a user picks country · carrier · box type and enters flower cost. The system pulls the matching rule, computes freight ($/kg × box weight), tariff (cost × tariff %), fuel surcharge, and lands the true cost into Inventory — no manual math required anywhere else.
