A useful trade plan ends with a decision, not a prediction. Build a scenario sheet before approving the next purchase order.
Practical frameworks are editorial recommendations. All worked examples are hypothetical, not client results. Confirm transaction-specific legal, tax and safety requirements with a qualified professional.
Plan for variability
Compare a normal delivery schedule with a delayed-shipment scenario. Identify which orders need alternative suppliers, transport routes or extra stock.
- Record demand, usable stock, supplier capacity, delivery date and the decision owner. Stress-test a delayed shipment and unavailable supplier; OECD resilience research supports managing dependencies rather than assuming domestic supply eliminates risk.
Compare landed costs
Include freight, insurance, duties and handling when comparing suppliers. A lower unit price may not mean a lower delivered cost.
- Use one currency and delivery scope. Separate confirmed charges from assumptions, and record the quote expiry. Compare purchase price, freight, duties, handling and inventory cost without counting an included charge twice.
Worked example
Hypothetical decision: an alternative supplier has a higher unit price but a shorter qualified lead time. Compare its complete delivered cost with the cost of a production stop. A cheaper quote is not automatically the lower-risk decision.
Review decisions regularly
Review supplier performance, transport capacity and official trade notices before each purchasing cycle. This guide is a planning framework, not a market forecast.
- Set a trigger before disruption: activate a qualified alternative when projected stock cannot cover recovery time. Record who approves extra cost, who checks specifications and who informs the customer; review assumptions after each delivery.
