The gap between placing an order and units being sellable on Amazon is long, often months once you count production, ocean freight, customs, prep, and FBA check-in. Every step has slack, and slack stacks, so the shelf goes empty long after the mistake was made.
We track suppliers' production before dates slip, hold the right buffer on SKUs that cannot go out of stock, and when a delay is real, make the air-versus-ocean and split-shipment calls fast with freight and supplier relationships already in place.
