What Is an Order Management System?
An order management system (OMS) is software that helps businesses manage customer orders from order capture through inventory allocation, fulfillment, shipping, and returns. It connects order information with the inventory, warehouse, purchasing, and customer data needed to move orders through the business.
For example, when a customer places an order, the system can help teams check availability, reserve stock, coordinate fulfillment, and monitor progress. Sharing this information across departments reduces manual handoffs and helps employees answer questions about availability and order status.
An OMS can operate as a standalone application connected to other systems or as part of an enterprise resource planning (ERP) solution. ERP order management connects these activities with broader business processes, including purchasing and accounting.
How Does an Order Management System Work?
An order management system coordinates the information and tasks needed to move an order from purchase to completion. A typical order management process includes:
- Capture the order. Record customer details, products, quantities, pricing, and delivery requirements from sales teams or connected sales channels.
- Check availability and allocate inventory. Determine whether stock is available and reserve it for fulfillment. If items are unavailable, coordinate replenishment, backorders, or another sourcing option.
- Coordinate fulfillment and shipping. Pass order details to the appropriate warehouse or fulfillment team and update the order as items are picked, packed, and shipped.
- Connect billing and customer updates. Share fulfillment information with accounting and make order status available to employees and, where configured, customers.
- Manage returns and review performance. Record returns, exchanges, or credits and use reporting to identify delays and recurring issues.
The exact workflow depends on the business, its fulfillment methods, and the systems or integrations in place.
Benefits of an Order Management System
An order management system creates value by helping sales, warehouse, purchasing, and customer service teams work from consistent information. When these activities are connected, businesses can reduce repetitive tasks, identify fulfillment problems earlier, and respond more effectively to customers.
With the right order management system, businesses have the tools they need to address such customer concerns immediately, but they will also be able to proactively prevent these concerns from occurring in the first place. Here’s how.
Improved Efficiencies with Automated Sales Processes
An Order management systems can reduce repetitive work by carrying order information through connected sales and fulfillment processes. Depending on its configuration, it can apply pricing rules, update order statuses, and share transaction details without requiring employees to enter the same information in multiple places.
This helps reduce manual errors and gives employees more time to manage exceptions, such as incomplete orders, pricing discrepancies, or unavailable items.
Inventory Visibility and Control
Connecting order management with inventory management helps teams see what is available, where it is located, and what has already been allocated to other orders. This information supports more informed fulfillment decisions and helps sales teams communicate realistic availability to customers.
When purchasing and replenishment processes are also connected, teams can use demand and stock information to identify shortages and determine when additional inventory is needed. Accurate records and timely transaction updates remain essential.
Such robust inventory control and visibility prevents inventory headaches and reduces operational costs.
Expanded and Advanced Reporting and Analytics
Order management reporting helps teams monitor open orders, backorders, fulfillment times, and other measures of performance. Comparing results across products, locations, or sales channels can reveal where delays and exceptions occur.
For example, a recurring backlog at one warehouse may prompt a review of stock availability, staffing, or fulfillment procedures. Reporting gives teams a starting point for investigating the cause and deciding what to change.
Customer Experience and Fulfillment
Access to consistent order and inventory information helps employees answer customer questions about availability, shipment progress, and returns. It also makes it easier for sales, warehouse, and customer service teams to coordinate when an order changes or a problem arises.
More reliable processing and clearer communication can help businesses meet customer expectations and build trust over time.
Implementing Order Management Software in Your Business
Businesses can choose a standalone order management system or order management capabilities within an ERP solution. The right approach depends on the processes you need to connect, your existing systems, and how orders move through your business.
Before evaluating options, map your workflow from order entry through fulfillment and returns. Identify where employees repeat work, lose visibility, or rely on manual updates, then assess how each solution would address those gaps.
Acumatica’s order management software connects sales orders with purchasing, inventory, pricing, and fulfillment within Acumatica Cloud ERP. This gives teams a shared view of order activity and the information needed to coordinate processing across departments.
“Acumatica makes it a hell of a lot easier to sell in a product, knowing that we’ve got full control of where it comes from and where it goes. It’s an amazing tool for the team and gives us a whole new level of clarity and focus when consulting with the customer, which is key as our customers’ time and attention is constrained as it is, managing their own busy operations.”
Order Management in Practice: Cave Direct
Cave Direct, a UK importer and distributor of specialty and craft beer, illustrates the value of connecting order management with inventory and financial information. Before implementing Acumatica, the company relied on a legacy system and spreadsheets, making it difficult for sales employees to see stock availability across its warehouses.
With Acumatica Distribution Edition, Cave Direct gained real-time inventory visibility and connected its operations with ordering and customer management applications. Its experience shows how shared information can support both fulfillment decisions and customer conversations.
Cave Direct needed a digital platform with multi-currency capabilities, a real-time inventory management system, eCommerce functionalities, and the ability to integrate with their critical third-party applications. After evaluating several ERP contenders, including Oracle NetSuite, Acumatica was the clear winner.
“We chose Acumatica for its flexibility and online order management capabilities,” says Louise Smale, Co-founder and Managing Director of Cave Direct.
With assistance from Acumatica partner Arcus Universe, Cave Direct implemented Acumatica’s complete Distribution Management Edition, which includes our Order Management module. In addition to helping Cave Direct keep operations going during COVID-19 lockdowns, navigate complicated Brexit tax requirements, and automate and streamline operational workflows, Acumatica has also given the company full inventory visibility.
“Having that stock control is incredible. That’s put us at the forefront, especially in the craft beer industry. Now we can track it all; everything we do is in Acumatica. Whatever information we want, we can have it at the click of a button, and that’s the key to our success. We know what’s in each warehouse and when goods are sold.”
