The prime objective of most warehouses is to facilitate the movement of goods through the supply chain to the end consumer. It is often necessary to hold inventory, when
- The demand for the product is continual
- The supply lead time is greater than the demand lead time
Inventory is therefore often beneficial to smooth variations between supply and demand.
There are two types of storage actions performed,
Planned Storage: Planned storage is the storage required as planned to meet the regular customer demand. The inventory received in the warehouse requires storage for a certain period of time where the duration of storage may vary.
Extended Storage: Extended storage involves storage of inventory in excess of normal warehouse operation. Some of the reasons for extended storage requirements are seasonal demand, erratic demand, discounts, speculative purchases, product conditioning, etc.
- In order to meet the erratic or seasonality in demand an additional storage of goods in terms of safety stocks could be required.
- Some products such as food items may be stored for conditioning purposes.
- Sometimes a firm may buy bulk quantities to avail the discounts that are available or to purchase when the price is low. This is speculative purchases as the goods are bought at a higher quantity due to lower price or due to expectation of higher price in the future.
- Sometimes due to promotional campaigns such as sales promotion, additional stock may be required to be kept to meet the expected higher demand for the product.
Smooth Movement of Goods
Movement of goods involves inbound activity i.e., unloading of goods brought to warehouse, transfer to storage by transferring the goods from the inbound area to the storage area, order selection involves selection of good in the storage as per order to be shipped and transferring it to shipment area and outbound activity involving checking and loading the gods for shipment.
Managing Information
It helps in keeping a track of information regarding goods that have arrived at the warehouse, stored and shipped out of the warehouse. All the required information relating to the warehouse is stored. All the data is captured by the information system in the warehouse is then passed on to the higher management in order to take better decisions.
Protection of Goods
Warehouse provides protection to goods from loss or damage due to heat, rain, dust, wind etc. It requires special arrangements for different types of products as per their respective nature. Warehouses help in cutting down losses due to spoilage and wastage during storage.
Bearing the Risk
Warehouses aids in taking over the risks incidental to storage of goods. When the goods are received in a warehouse then it is the responsibility of, these goods passes on to the warehouse-keeper. The risk of loss or damage to goods in storage is thus borne by the warehouse keeper. The warehouse is bound to return the goods in good condition and is responsible for any loss, theft or damage etc. Therefore, they take all precautions to prevent any kind of mishap.
Warehouse Financing
For goods deposited in any warehouse, the depositor gets a receipt, which acts as a proof about the deposit of goods. The warehouses can also issue a document in favour of the owner of the goods, which is called warehouse-keeper’s warrant. This warrant is a document of title and can be transferred by simple endorsement and delivery. The businessmen can also obtain loans from banks and other financial institutions by keeping this warrant as security. In some cases, warehouses also give advances of money to the depositors for a short period keeping their goods as security.
Processing
There are certain commodities which are not consumed in the form they are produced. It requires some processing to make them consumable. Sometimes warehouses also undertake these activities on behalf of the owners.
Grading and Branding
Warehouses also perform the functions of grading and branding of goods on behalf of the manufacturer, wholesaler or the importer of goods. It also provides facilities for mixing, blending and packaging of goods for the convenience of handling and sale.
