Existing inventory refers to the quantity or value of inventory goods or materials actually available to an enterprise or warehouse. Existing inventory is the basis for enterprises to carry out production and sales activities, as well as a key link in warehouse material reserves and management.

For enterprises, existing inventory mainly includes raw materials, semi-finished products, finished products and other inventory goods, as well as auxiliary materials, tools, equipment and other materials. The quantity and value of these inventory goods and materials are the basis and guarantee for enterprises to carry out production and sales activities. If the existing inventory is insufficient, enterprises may face problems such as production interruptions or sales shortages; if the existing inventory is too high, it may result in inventory backlog and capital occupation, increasing the operating costs and risks of enterprises.

For warehouses, existing inventory mainly refers to the quantity and value of materials actually available in the warehouse. Warehouses need to reasonably arrange material reserves and management based on material demand and supply situations to ensure a balance between material supply and demand. If there is too much inventory in the warehouse, it may result in a waste of warehouse space and material backlog; if the existing inventory is insufficient, it may cause material supply interruptions or delays, affecting the normal production and sales activities.

Therefore, enterprises need to reasonably control the quantity and value of existing inventory, formulate reasonable inventory management strategies and plans based on production and sales needs and plans to avoid inventory backlog and waste, and improve operating efficiency and competitiveness.
