What is an Order Management System (OMS)?

When you have a brand new business, only a few orders come in each day and you can easily fulfill them yourself at a low cost. However, as customer demands rise and sales multiply, your order management requirements will change. You may no longer be able to package and ship products yourself, neither quickly nor cheaply. Maybe you’ll need to fulfill orders through a warehouse, or through multiple warehouses to route orders to their destination.

This is where an order management system can help you meet your changing order management requirements and scale the operational processes you need. Integrating an OMS can help retailers address complexities including inventory management, inventory visibility, inventory routing, or facilitating an omnichannel experience.

By managing orders from all of your sales channels across customer, financial, inventory and supply chain touchpoints, an order management system can drive customer satisfaction, brand loyalty and repeat purchases. How effectively you manage your customers’ orders will directly impact the success of your business.

What is an Order Management System (OMS)? 

Shopify defines an Order Management System (OMS) as:

“Any tool or platform that tracks sales, orders, inventory, and fulfillment as well as enables the people, processes, and partnerships necessary for products to find their way to the customers who bought them.”

Simply put, an order management system manages orders from all sales channels. Centralizing data in one system is critical to giving you a single view of demand, inventory and supply, so you can exceed customer expectations for buying, fulfilling and returning anywhere, anytime.

As the buyer landscape and expectations change, order management has adopted a multi-dimensional approach that touches many business operational facets. These facets include customers, sales channels, product information and location, inventory levels, returns and refunds, order printing and packaging, as well as order picking, processing and shipping.

Serving as a complete supply chain to your business operations, your order management system should be able to: 

  • Update inventory counts across systems and sales channels
  • Forecast stock levels to ensure you don’t run out of products
  • Accept orders regardless of payment currency or chanel origin
  • Track all orders for both customers and customer service teams
  • Communicate order details to warehouses or 3PLs for fulfillment
  • Provide back-office functionality like accounts receivable, accounts payable, and the ability to generate invoices and accept payments

Order Management System benefits

Choosing to use an OMS can benefit retailers by providing a comprehensive view of inventory, suppliers, and manufacturing facilities to your warehouse and physical retail stores. A centralized order management system ensures fast, accurate and seamless experiences across your entire business and supply chain. It helps you stay organized, avoid costly mistakes, and respond faster to customer demands and marketplace changes.

Benefits you can expect from investing in a good order management system include:

  • Eliminate chances of over-ordering
  • Avoid unwanted inventory recounts
  • Stop spending time or money selling slow moving products
  • Improve efficiency and productivity with devices like barcode scanners
  • More automated processes and less error-prone manual processes
  • Increase customer loyalty by always having products that are in-demand
  • Provide data to customers including order status, or manage returns and exchanges

How an order management system can support an omnichannel experience


An order management system can benefit companies who operate both physical and online storefronts to provide a single view of demand, inventory and supply. For example, if a customer places an order online and picks up in store, the retailer will require an OMS with multichannel inventory visibility and order fulfillment to track this order.

According to JRNI’s Annual Modern Consumer Research Report, nearly 74% of consumers research products online and purchase them in store. Even when consumers purchase online, 55% of consumers would schedule appointments with in-store staff if given the opportunity. Additionally, 57% of consumers research products in store and purchase online.

This research demonstrates that many ecommerce businesses today may require different operational requirements as customer demands change. An OMS can help merchants with omnichannel strategies by providing information on orders and inventory across all channels in real time.

Order Management System features to consider

Order management systems share many key features that support the sales process. This includes increasing time efficiency and reducing errors to help companies run smoothly. Here are 8 features you should look for when choosing your order management system (OMS):

1. Multi-channel order management

Your OMS should ideally bring all your channels into a centralized system. This ensures you can create sales orders whether customers order online or in store. This also keeps track of wholesale requests, and all of your orders from all commerce channels.

2. Product management

Inventory management is the foundation for your business. An OMS should help you see all your product information in a single place. You should be able to organize products by categories, and enter cost data and purchase prices.

3. Customer management  

Customers are essential to driving business to your store. This is why it’s important to keep track of their interactions and payment status. An OMS should keep important information like a history of customer interactions, sales orders and shipments.

4. Inventory management

It’s important that your OMS tracks stock numbers for every product. This ensures you know how much inventory you can sell. Your system should consider every purchase or sale, whether it is physically in your inventory or a back order.

5. Returns processing

Your OMS should have returns processing capabilities with a procedure in place for reentering merchandise into your inventory after returns, reimbursing your customers, and ensuring a stress-free returns processing environment for merchants.

6. Easy integration with tools

An OMS should give you the flexibility to integrate tools you need to expedite and ensure an accurate order fulfillment process. For example, multi-channel support can help you sync with ecommerce or business applications like Amazon, financial apps, and fulfillment providers.

7. Multiple payment gateways supported

Merchants will benefit from providing buyers with the ability to pay regardless of channel origin or currency. Therefore it’s important to look for an OMS that supports multiple payment options and which can integrate with fraud check services for security.

8. Distance-based routing

An OMS should route orders intelligently based on distance. For example, if a company uses multiple fulfillment centres to ship orders, the closest fulfillment centre to the customer’s location will ship the order. This ensures the fastest and most efficient delivery.

Choosing an OMS Shopify Plus partner
