Many manufacturers benefit greatly from On-Demand Stock and Just-In-Time (JIT) Delivery Programs, such as those offered by PPCP. On-Demand Stock is a stocking or consignment program that allows customers to order key parts and be invoiced when the parts are used, rather than at the time they are shipped. Both time and cost are saved in addition to ensuring that parts are immediate available. Just-In-Time (JIT) Delivery is an inventory control program that adds efficiency and reduces waste by shipping parts at the time they are required for production. This can cut inventory costs and add profits, when accurate forecasting is in place.
