Total time between placing a purchase order and receiving goods in inventory.
Why It Matters
Lead time determines how far ahead you need to plan inventory. Longer lead times require larger safety stocks and earlier reorder points. Understanding and reducing lead time improves cash flow, reduces stockout risk, and increases operational agility.
Practical Example
Scenario
A skincare brand maps complete lead time for their overseas-manufactured products.
Calculation
Production: 25 days. Ocean freight: 35 days. Port clearance: 5 days. Last-mile to warehouse: 3 days. Total lead time: 68 daysResult
68-day lead time means reordering nearly 10 weeks before needing product. Any demand spike within that window can't be addressed—highlighting need for higher safety stock.
Pro Tips
- 1Map lead time component by component to identify reduction opportunities
- 2Negotiate with suppliers—sometimes faster production is possible at modest premium
- 3Air freight option (even occasionally) provides emergency flexibility
- 4Track actual lead times vs quoted—suppliers often underestimate
Common Mistakes to Avoid
Using quoted lead time without verifying actual historical performance
Forgetting components: customs, port congestion, last-mile
Not having backup suppliers when lead time is critical
