Just-in-Time Inventory (JIT)

Just-in-time (JIT) inventory is a stock management approach where materials and goods are ordered and received only when they are needed for production or sale, reducing storage costs, waste and cash tied up in inventory.

What is just-in-time inventory?

JIT was pioneered by Toyota as part of the Toyota Production System. Instead of holding large stockpiles "just in case", a business keeps minimal inventory and relies on frequent, reliable deliveries timed to demand.

Benefits

  • Less cash tied up in stock, improving [working capital](/glossary/working-capital)
  • Lower storage, insurance and handling costs
  • Less obsolete, expired or damaged stock
  • Faster detection of quality problems
  • Higher [inventory turnover](/glossary/inventory-turnover)

Risks

  • Supply disruption: a delayed delivery can halt production, as many businesses found during global supply chain shocks.
  • Demand spikes can lead to stockouts.
  • Requires accurate forecasting and strong supplier relationships.
  • Smaller, frequent orders may cost more per unit.

What it takes

  • Reliable, nearby suppliers
  • Accurate sales and production forecasting
  • Real-time inventory tracking
  • Clear reorder points and lead times

Example

A café orders fresh pastries daily based on the previous week's sales by weekday, rather than buying a week's supply on Monday. Waste falls and less cash sits in stock.
