Learn how the right WMS can create greater efficiency within the supply chain through greater visibility and integrated technology.

What Is a Warehouse Management System?

A Warehouse Management System (WMS) is a software solution (ideally cloud-based) that optimizes internal processes within a warehouse. A WMS tracks inventory from the moment it arrives at the warehouse to the moment it leaves on a last mile delivery vehicle. 

Warehouses use a WMS to ensure that the movement of goods through the warehouse is as efficient as possible to avoid inventory shrinkage and dedicate labor hours to the functions that matter most for on-time fulfillment: picking, packing, and shipping.

What is Warehouse Management?

Warehouse management is the process by which online sellers optimize warehouse performance to improve profit margin. Ideally, this is conducted via a single, cloud-based warehouse management system (WMS) integrated with merchants’ eCommerce stores and various marketplaces. 

The WMS should automate as many warehousing and fulfilment processes as possible via direct shopping cart integrations, marketplace integrations (ie Walmart Marketplace and Amazon), and electronic data interchange (EDI) connectors. As selling becomes increasingly complicated due to multichannel fulfillment, the WMS provides visibility into day-to-day operations and logistics and delivery statuses

A WMS that seamlessly integrates with a merchant’s ecommerce shopping cart and marketplace listings eliminates the need for multiple spreadsheets and manual order uploads. It also cuts down on customer service requests by sending customers regular updates on their fulfillment status and real-time delivery tracking.

A fully integrated WMS will help automate four major processes:

  • Order Management: New orders are automatically routed to the warehouse for fulfillment so there’s no lag time in fulfillment and no manual upload process.
  • Inventory Management: See inventory levels across all fulfilment centers and reallocate inventory based on demand through a single platform. This real-time visibility prevents stockouts, frustrating customer experiences, and missed sales opportunities.
  • Delivery Tracking: Tracking numbers will sync automatically with sales orders and send shipping confirmations to customers. Partnering with a trusted last mile carrier ensures that tracking information is up to date and reliable.
  • Reporting: Having all of this information integrated through a single platform allows for advanced reporting around demand forecasting and inventory balancing to enable proactive supply chain planning.

This level of integration allows sellers to forecast future demand and anticipate supply chain activities to take the guesswork out of inventory re-ordering and inventory distribution. Eventually, quickly-growing merchants may even be able to sell products without ever having physical possession of merchandise.  

Ultimately, eCommerce merchants that rely on a powerful WMS as part of their digital warehousing strategy make more efficient use of their time and money, allowing them to focus more resources on product development, marketing, and customer service.

Where a WMS Fits in the Supply Chain

A powerful WMS not only streamlines operations within the warehouse, but also feeds efficiency upstream within the overall supply chain. The right WMS will offer inventory insights and demand forecasting tools that help merchants determine:

  • Profitability at the SKU level to determine which SKUs they should prioritizing for reorder and which may be extraneous to their SKU profile.SKU velocity to determine the ideal reorder quantities that balance bulk supplier discounts with healthy inventory turns.Customer distribution and average Time in Transit (TNT). If a merchant discovers that the majority of their customers are concentrated on the East Coast, but they have been importing into a West Coast port, they may want to consider re-routing shipments to a secondary port closer to their end customers.

Optimizing eCommerce Operations with a Warehouse Management System 

eCommerce sales channels have evolved rapidly to help merchants scale their sales operations. Because ecommerce sales are all managed digitally, they handle growth seamlessly and inexpensively. However, many merchants face the challenge of scaling their fulfillment operations at the same pace to meet growing demand from their sales channels. This is where a powerful WMS can stand in the gap and help to digitize warehousing and fulfillment. 

Children’s furniture and toy retailer, ECR4Kids, found that when they relied on technology for their ecommerce fulfillment, they had the confidence to scale up quickly with spikes in demand.

Integrating all sales channels through a single WMS platform also makes inventory, sales, and shipping data much more actionable. For instance, the WMS lets merchants determine real-time stock availability, forecast inventory accuracy, and set reorder points in advance to mitigate shortages. It also enables highly accurate inventory cycle counts to reduce inventory shrinkage or obsolescence.

What’s more, this data can also be used to improve delivery speed and control bottom line costs. A smart WMS will utilize machine learning to recognize patterns in sales and shipping data to help ecommerce merchants understand where their best customers are located and their average price per shipment. With this data, merchants can choose warehouse placement that gets their inventory closer to their end customers, enabling 1 to 2-day ground shipping no matter where their customers are located. The benefits of a smarter distributed warehouse network are 2-fold:

  1. Meet Customer Expectations for Delivery Speed: Data shows that consumer expectations for fast shipping are continually increasing. Distributing inventory closer to end customers enables the fast shipping that ecommerce shoppers have come to expect.
  1. Control Fulfillment and Delivery Costs: Merchants who are fulfilling orders from a single warehouse are likely sending long-zone shipments to reach many of their customers. These long-zone shipments increase Time in Transit (TNT) and drive up costs. Distributed warehousing ensures that most shipments will be delivered in 1 to 2 days via ground, keeping costs down while meeting ecommerce shipping expectations.

Types of Warehouse Management Systems

Any merchant who has partnered with a small or regional 3PL knows that not all WMS are created equal. Often, regional 3PL’s will employ a Standalone WMS. These systems are typically housed on the warehouse’s server and only track functions within the warehouse. They support receiving and put-away tracking as well as pick, pack, and ship and inventory cycle counts. They often rely on manual processes but serve their purpose for small businesses operating from a single warehouse.

When businesses are ready to expand their warehouse distribution footprint to offer nationwide 1 to 2-day ground shipping, they may first opt to add more regional 3PL’s to their network. However, if each of these regional 3PL’s is operating on its own Standalone WMS, merchants will be stuck in the middle, switching between WMS platforms to monitor inventory levels and fulfillment statuses at each 3PL.

Businesses looking to gain more visibility into their fulfillment in order to scale quickly would be better served by an Integrated ERP System or an Cloud-based Warehouse Management System. An Integrated ERP will enable merchants to integrate their accounting, supply chain planning, and CRM functions into their WMS. While a Cloud-based WMS that connects all fulfillment centers across their network to give a high-level view of inventory levels and order and fulfillment statuses.
