By streamlining workflows, reducing errors, and optimizing fulfillment, OMS plays a pivotal role in enhancing ERP systems. This article explores the core functions, benefits, challenges, and future trends of OMS-ERP integration, with real-world examples to illustrate its impact.
What Are OMS and ERP, & Why Integrate Them?
An Order Management System (OMS) is a specialized platform designed to manage the entire order lifecycle—from order placement to fulfillment. It handles critical tasks like inventory allocation, order processing, and customer communication.
On the other hand, an Enterprise Resource Planning (ERP) system is a comprehensive solution that integrates various business functions, such as finance, human resources, inventory, and supply chain, into a unified platform.
Integrating OMS into an ERP system bridges the gap between order management and broader business operations. According to ERP League, an Aberdeen Group study highlights that businesses adopting ERP systems experience a 22% boost in operational efficiency and a 22% decrease in inventory costs.
This aligns with the general trend of enhanced efficiency through such integrations, as OMS streamlines order workflows and ERP ensures cohesive data management across business functions. For instance, a retailer using an OMS within an ERP can instantly update inventory levels across all sales channels, ensuring accurate stock information and reducing overselling risks.
Core Functions of OMS in an ERP System
Order Processing and Automation
The primary function of an OMS within an ERP is to automate and streamline order processing. It captures orders from multiple channels—eCommerce platforms, retail stores, or B2B portals—and consolidates them into a single system. Once an order is captured, the OMS validates it through fraud checks and payment verifications to ensure authenticity. Automated workflows then take over, handling approvals, generating invoices, and triggering fulfillment processes without manual intervention.
For example, Shopify, a leading eCommerce platform, integrates OMS functionalities into its ERP partnerships to automate order workflows. The system enables ecommerce businesses to handle multichannel orders—such as in-store transactions, online sales, and marketplace purchases—through one centralized platform.
Inventory Management
OMS enhances inventory management within an ERP by providing real-time stock updates across all warehouses and sales channels. This synchronization prevents stockouts and overselling, which are common pain points for businesses.
Additionally, OMS leverages historical data for demand forecasting, helping businesses optimize stock levels. It also supports dynamic stock allocation, prioritizing orders based on factors like customer location or delivery timelines.
Take the example of Zara, a global fashion retailer. Zara’s OMS, integrated into its ERP, allows the company to update inventory in real time across its 2,000+ stores worldwide. According to Apptunix, Zara leverages AI-driven demand forecasting to anticipate trends, streamline inventory, and stay ahead of competitors.
By examining real-time sales data, social media activity, and customer behavior, the AI identifies what products are in demand and in what quantities—ensuring stores are stocked with precisely what customers are looking for.
Multi-Channel Order Handling
In an omnichannel retail environment, customers expect a seamless experience across websites, marketplaces like Amazon, and physical stores. OMS enables this by consolidating orders from all channels into a single system. It also supports complex order scenarios, such as splitting orders across multiple warehouses or bundling items for a single shipment.
Furthermore, OMS keeps customers informed with real-time updates on order status, enhancing transparency. Walmart provides a real-world example of effective multi-channel order handling. By integrating an OMS into its ERP, Walmart manages orders from its website, app, and physical stores seamlessly.
Payment and Billing Integration
OMS integrates payment gateways into the ERP, supporting multiple payment methods like credit cards, digital wallets, and bank transfers. It automates billing and invoicing based on order details, ensuring accuracy and speed. Additionally, OMS facilitates financial reconciliation by syncing order data with the ERP’s accounting module, providing a clear view of revenue streams.
For instance, a small business using NetSuite’s ERP with an integrated OMS can process payments from Stripe, PayPal, and direct bank transfers. The system automatically generates invoices and reconciles payments, reducing manual accounting errors.
OMS’ Role in Supply Chain Optimization
Order Routing and Fulfillment
OMS optimizes supply chain operations by dynamically assigning orders to the best fulfillment centers based on proximity, inventory availability, and cost. It also selects the most cost-effective shipping options by comparing carriers and delivery timelines. Real-time tracking ensures customers and businesses stay informed about shipment statuses.
A 2024 article by ShipBob highlights the impact of an Order Management System (OMS) on fulfillment efficiency. According to the article, businesses using ShipBob’s OMS and warehouse management system (WMS) integration saw a significant reduction in shipping costs and improvement in delivery speeds by automatically routing orders to the nearest fulfillment center.
Returns and Reverse Logistics
Returns are a significant challenge in eCommerce, with return rates doubling since 2019 from 8.1% to 16.9%, as per NRF report. OMS streamlines returns by automating workflows for refunds and exchanges. It also manages restocking and adjusts inventory levels efficiently, minimizing disruptions. Additionally, OMS tracks return reasons, providing insights for process improvements and boosting customer satisfaction.
According to a 2023 article by The Guardian, ASOS reported that just 6% of its shoppers, identified as frequent returners, contributed to a £100 million reduction in profits due to their high return rates. This highlights the significant impact of returns on ASOS’s operations and underscores their efforts to manage returns more effectively through systems like an OMS within their ERP.
Benefits of OMS-ERP Integration
The integration of OMS into ERP systems offers several benefits:
Operational Efficiency: By automating workflows and reducing manual errors, OMS-ERP integration improves order accuracy. A study by Aberdeen Group found that businesses with integrated systems achieve 22% higher on-time delivery rates compared to those without such integration.
Customer Satisfaction: Faster order processing, accurate tracking, and fewer errors enhance the customer experience. Companies like Zappos have leveraged integration systems to ensure timely deliveries and transparent communication.
Data-Driven Insights: OMS provides analytics for demand forecasting and inventory planning, enabling businesses to make informed decisions. For example, Nike uses OMS data within its ERP to predict demand for new sneaker releases, optimizing production and inventory allocation.
Challenges and Considerations
Despite its benefits, OMS-ERP integration comes with challenges. First, integration complexity can lead to data silos if not implemented correctly, requiring robust APIs and middleware. Second, scalability and customization are critical—businesses must ensure the OMS can adapt to growth and unique workflows.
Finally, compliance and security are paramount, especially with regulations like GDPR and CCPA. OMS-ERP systems must protect customer data and meet regulatory requirements.
A European retailer, Palmers Textil AG, successfully integrated the FIEGE OMS with its SAP ERP by migrating its e-commerce platform from SAP Hybris to Magento 2. Despite initial challenges with data migration and system connectivity using FTP and XML, the integration streamlined order processing and improved customer experience, resulting in greater operational efficiency and a scalable IT infrastructure.
