A manufacturing company has entered into a new contract with a major supplier of raw materials used in the manufacturing process
Slav-nsk [51]

Answer:

It allows the plant to function more efficiently, as it increases the inventory turnover ratio.

Explanation:

Vendor Managed Inventory (VMI) is a kind of business model in which the buyer of a certain products gives information to a vendor of that same product and the vendor acquires total responsibility for holding on to the agreed inventory of that same material, majorly at the buyer's consumption location as we can see from this question.

Vendor managed inventory contract permits manufacturer to have a close instant entry to inventory. This immediate connection permits the customer to pull inventory as when due and only make payment for what is consumed. This will in turn reduce inventory investment and cause a higher inventory turns.

The VMI is known to provide vendors more control in order to rightly forecast demand, Boost Customer-Vendor Relationships, decrease Inventory Costs, Reduced Inventory Overstocks and Stock Shortage with an improvement in Sales.
