Definition
Lead time is the full door-to-door delay: supplier production, transit, customs, 3PL receiving and put-away — until units are available to sell. Using only ocean transit days understates risk and makes reorder points too low.
Worked example
Factory 10 days + ocean 28 + customs 4 + 3PL receive/put-away 3 = 45 days door-to-door. If you only counted 28, you reorder too late.
Why it matters for replenishment
Lead time multiplies daily demand in the reorder point. Understated lead time is a top cause of stockouts on imported goods.
How OmniRestock uses this
OmniRestock uses supplier lead times when it builds stockout and order-by dates and when it sizes replenishment suggestions.
