Warehouses are a very important part of the supply chain today. In the past, warehouses were just places for storing goods, but in today’s scenario, warehouses are supposed to receive goods, maintain accurate stock records, fill orders quickly, and deliver them to the customer promptly.
As businesses process large number of orders, increased amounts of goods, and more complex distribution systems, the manual system of running warehouses can prove to be very challenging. Errors in the records, picking, packing and dispatching can prove to be a hindrance and add to the costs of the business.
A warehouse management system can help businesses get over this issue by helping them have better control over their warehouse operations.
The warehouse management system helps in managing various tasks such as inventory management, location management, receiving, picking, packing, replenishment and shipping in the warehouse.
What Is a Warehouse Management System?
Warehouse Management System or WMS as it is popularly known as, is a software system that helps in managing warehouse operations.
It assists companies to keep track of their inventory, as well as coordinating the movement of inventory from the time they arrive in the warehouse until they have been picked up, packed and shipped out.
A warehouse management system can assist in the following tasks:
- Receiving goods
- Inventory tracking
- Putaway
- Storage location management
- Stock replenishment
- Order picking
- Packing
- Dispatch
- Cycle counting
- Returns processing
- Reporting and analytics
The WMS allows warehouse workers to gain access to updated data about the inventory without relying excessively on paper and spreadsheet methods.
This could make the warehouse processes easier to manage.
How Does a Warehouse Management System Work?
A WMS manages the inventory as it is moved through the various stages in the warehouse process.
Normally, the process starts with goods arriving at the receiving point.
The software captures details of the goods and, depending on the kind of goods and the capacity among others, it might recommend suitable places where the items should be stored.
When customers place their orders, the WMS creates picking instructions and directs the staff members to the right places.
A normal warehouse process might be as follows:
- Goods arrive at the warehouse.
- Products are inspected after receiving.
- Inventory information is recorded.
- Storage locations are assigned.
- Products are shifted to their respective destinations.
- Customer orders are received.
- Picking instructions are generated.
- Selection and packing of products.
- Preparation for shipping takes place.
- Inventory management is done automatically.
Through the coordination of these activities, the warehouse management system becomes a useful tool that reduces manual activity and increases visibility within the warehouse.
Why Businesses Need a Warehouse Management System
Managing warehouse operations becomes increasingly difficult as a firm expands.
A business might begin its operations with a smaller set of products and simpler inventory needs. With time, the number of SKUs, orders, customers, suppliers, and storage areas could increase.
Some of the problems that could arise in the absence of an organized system include:
- Incorrect inventory records
- Difficulty locating stock
- Picking errors
- Overstocking
- Stock shortages
- Slow order fulfilment
- Poor warehouse space utilisation
- Limited operational visibility
The warehouse management system offers a centralized system for managing these activities.
It allows firms to have clear visibility of the inventory on hand, where it is kept, and its movement inside the warehouse.
This is important in making better-informed decisions and increasing control over logistics processes.
Key Benefits of a Warehouse Management System
- Improved Inventory Accuracy
In order to conduct warehouse operations effectively, it is important to have correct data on inventory.
If this is not the case, companies might think that there is enough stock available even though there isn’t.
The use of WMS will help keep better data on inventory as the movements of stock will be recorded automatically.
Once goods have been received, transported, picked, or delivered, inventory can automatically be accounted for.
A barcode reader or RFID can also be employed for decreasing the need for data entry manually.
Improving the accuracy of their inventory enables organizations to do better planning and make customer-oriented decisions.
- Faster Order Fulfilment
Consumers today demand fast handling and delivery of their orders.
A warehouse management system can assist in accelerating the fulfillment process by optimizing picking, packing, and shipping procedures.
There will be no need for the staff to look for the product since there is already a system that will give clear direction where the product can be found.
The system will be able to identify the best route for order picking.
This will lessen the amount of time the staff needs to move around in the warehouse.
This will increase productivity since orders will be processed faster.
- Reduced Picking and Packing Errors
Warehouses make costly mistakes.
Wrong product selection, wrong quantity, and wrong packaging of products may lead to return of goods and additional expenses on delivery.
A warehouse management system reduces such mistakes due to its standardised process flow and precise data about orders.
The scanning system can also ensure that the right product has been selected for the order.
It will be easier for the staff in the warehouse to perform these activities according to the process.
It will help to increase the accuracy of orders.
- Better Warehouse Space Utilisation
Storage space can be expensive for many firms.
Disorganisation within the warehouse can lead to wastage of space, cluttering, and unnecessary movements.
The use of warehouse management software can assist the firm in utilising storage space effectively.
The placement of items in the warehouse can be done according to the product attributes or storage availability.
Quick-moving goods, for instance, can be put nearer to packing or shipping zones.
Slow-moving stock may be kept in places that are infrequently used.
Effective allocation and storage will help increase efficiency by eliminating wasteful travel around the warehouse.
- Greater Operational Visibility
One of the greatest benefits of warehouse management systems is enhanced visibility.
The manager should be aware of what inventory exists in the warehouse, its location, current orders being fulfilled, and where bottlenecks are.
A warehouse management system provides current information about operations at the warehouse.
This enables managers to recognize issues faster and react to them.
More visibility will aid in communication among warehouse staff, buyers, sellers, transportation workers, and customer service staff.
Warehouse Management System and Inventory Management
The warehouse management system and inventory management system are similar; however, they differ slightly.
The main role of inventory management is to monitor the quantity of products, availability, and overall stock.
The warehouse management system takes care of the handling of stock within the warehouse.
It entails:
- Receiving
- Putaway
- Location management
- Picking
- Packing
- Replenishment
- Dispatch
For firms with complicated warehouse functions, WMS enables greater monitoring of the process of handling goods within the storage and fulfillment functions.
Warehouse Management System and Transport Management System
Transportation and warehousing functions go hand-in-hand.
The warehouse management system monitors goods when they are within the warehouse.
The transport management system, or TMS, monitors the movement of the goods from one place to another.
For instance, WMS will verify that the item has been picked, packed and is ready for pick up.
TMS, on the other hand, will organize for its delivery and even assign a carrier or a vehicle for that purpose and trace the process throughout.
WMS and TMS integration can enhance the coordination of the warehouse and transportation processes.
This can help avoid any problems with loading and lead to better efficiency in outbound logistics.
Warehouse Management System and Order Management System
Order Management System is responsible for customer orders from their generation through to their completion.
Warehousing management system controls all the warehouse processes necessary for order fulfillment.
After the confirmation of order, the order management system could provide instructions for order fulfillment to the warehousing management system.
Then, the warehouse management system could control the picking, packaging, and shipping.
The connection of order management and warehouse management systems ensures improved visibility across the entire process of fulfillment for the business.
It is particularly useful for retailers, e-commerce firms, and distributors with large order quantities.
Key Features of a Warehouse Management System
Not all warehouses need to have the same abilities.
An appropriate system should be chosen depending on the business.
Important features may include:
Receiving Management
