Order management system (OMS)
For B2B organizations with complex products, pricing and logistics, an OMS is essential to keep promises on availability, delivery dates and service.
What is an order management system?
An order management system (OMS) is specialized software that tracks and controls the entire lifecycle of a customer order – from capture across all sales channels, through validation, inventory checks and payment, to fulfillment, shipping and after-sales service. In B2B e-commerce, an OMS acts as a central brain that connects your web store, ERP, CRM, warehouse management and logistics partners. It consolidates order data, inventory availability and customer information in one place, so you can automate complex processes such as split shipments, backorders, multi-warehouse sourcing or approval workflows. The result is higher process efficiency, fewer errors, and a more reliable buying experience for your customers.
What does an order management system do?
An order management system centralizes and coordinates everything that happens between the moment an order is placed and the moment it is delivered and invoiced. It collects orders from all sales channels, checks customer data and credit limits, reserves inventory, selects the best fulfillment location, triggers picking, packing and shipping, updates order status, and feeds tracking information back to customers and internal teams.
Benefits of an order management system for B2B e-commerce
Unified view of all orders:
Consolidates orders from web shops, marketplaces, EDI, field sales and customer service into a single system. This makes it easier to monitor order intake, prioritize fulfillment and answer customer inquiries quickly.
Reliable delivery promises:
By combining real-time inventory visibility with business rules for sourcing and routing, an OMS allows you to provide realistic delivery dates and keep them – even when demand fluctuates or stock is distributed across many locations.
Higher process efficiency:
Automates routine tasks such as order validation, credit checks, split shipments and invoice generation. This reduces manual effort, lowers the risk of errors and frees up customer service and sales teams to focus on value-adding activities.
Better customer experience and self-service:
With an OMS behind your digital channels, customers can see accurate stock levels, track orders in real time, access their full order history and reorder with a few clicks. This transparency builds trust and reduces the number of support tickets.
Scalable omnichannel fulfillment:
Modern OMS solutions support distributed order management, allowing you to fulfill from multiple warehouses, plants or stores. You can implement scenarios such as ship-from-store, click-and-collect or drop shipment without disrupting your back-end systems.
Stronger data foundation for optimization:
Because an OMS collects detailed information on every order, it becomes a rich data source for analyzing lead times, fill rates, returns and customer behavior. These insights can be used to improve forecasting, planning and service levels.
Intershop Order Management is used by leading B2B companies to streamline complex ordering processes and deliver a consistent buying experience across all digital channels. By acting as a middleware layer between commerce platforms and fulfillment, it ensures transparency and reliable self-services for end customers.

Challenges and how an OMS solves them
Challenge 1: Fragmented order data across channels
Many B2B organizations take orders through web shops, email, phone, EDI and marketplaces. Without a central system, data lives in silos: order status is unclear, double entries are common and customers receive inconsistent information.
- Solution: Centralize order capture on an OMS
An OMS aggregates orders from all channels in one place. With Intershop Order Management, for example, incoming orders from your digital commerce front ends, ERP and sales representatives can be consolidated into a single view. This enables consistent processing, better prioritization and faster response times.
Challenge 2: Limited inventory visibility and overselling
If inventory data is maintained separately in ERP, warehouse and local systems, it is difficult to know what is actually available to promise. The result can be overselling, backorders and expensive emergency shipments.
- Solution: Real-time inventory and distributed order management
An OMS can maintain a consolidated, near real-time view of stock levels across warehouses, plants and stores. Rules-based order routing helps allocate stock from the optimal location. Intershop Order Management is designed to provide transparency across distributed inventory and to support complex sourcing scenarios.
Challenge 3: Complex B2B pricing and approval workflows
B2B orders often involve contract-specific pricing, budgets, internal approvals and partial deliveries. Handling these requirements manually slows down order processing and increases error risk.
- Solution: Configurable business rules and workflows
With an OMS, you can encode pricing, discount and approval logic into configurable rules. Orders can be automatically checked against contracts, routed for approval and split into multiple deliveries if needed, while still providing customers with a single, coherent view of their order.
Challenge 4: Legacy back-end systems limit agility
Many manufacturers and wholesalers rely on stable but inflexible ERP systems. Changing order flows directly in ERP is risky and slow, making it harder to support new digital business models or channels.
- Solution: Use an OMS as e-commerce middleware
Positioning an OMS between your commerce front ends and fulfillment systems allows you to innovate faster without replacing your core ERP. Intershop Order Management, for instance, acts as middleware that bridges commerce platforms and fulfillment, orchestrating orders while your existing systems remain in place.
Challenge 5: Lack of transparency for customers and internal teams
Sales, customer service and customers themselves often have different views of order status. Information is scattered across emails, ERP and spreadsheets, leading to time-consuming status checks and frustration.
- Solution: Single source of truth for order information
An OMS becomes the authoritative system for order and fulfillment information. Integrated with your portals and contact center tools, it provides a single place to view order history, invoices, returns and real-time status updates – for both employees and customers.
By addressing these common challenges, an enterprise-grade OMS such as Intershop Order Management helps B2B companies modernize their order processing and lay the foundation for scalable digital commerce.
Use cases for B2B order management systems
Manufacturing: Spare parts and after-sales service
A machinery manufacturer sells spare parts and services to dealers and operators worldwide. Orders come in via web shop, service technicians and EDI. With an OMS, the manufacturer centralizes all orders, checks stock across multiple plants and warehouses, and orchestrates fulfillment from the optimal location. Customers benefit from accurate availability information, reliable delivery dates and a complete order history in their self-service portal.
Wholesale distribution: Multi-channel inventory promise
A wholesale distributor supplies thousands of SKUs to retailers, online resellers and B2B end customers. By introducing a cloud-based OMS, the distributor gains real-time visibility into inventory and orders across channels. The system automatically reserves stock, prevents overselling and offers customers more flexible delivery options such as split shipments and drop shipping.
Industrial supplies: Complex orders and agreements
An industrial supplies company manages large contracts with customer-specific pricing, budgets and delivery schedules. An OMS helps apply contract conditions consistently, route orders for internal approval and coordinate partial deliveries over longer time periods. Integration with the B2B e-commerce portal ensures that buyers see the same conditions and status updates online as internal teams do in back-end systems.
In all these scenarios, an OMS is the backbone that connects the customer experience at the front end with the operational reality of inventory, logistics, and finance, making complex B2B commerce manageable on a large scale.
Technology and tools behind modern OMS solutions
Composable, API-first architecture
Modern B2B platforms increasingly follow composable commerce principles. In the Intershop Commerce Platform, for example, order management is implemented as a Packaged Business Capability that exposes its functions via APIs. This makes it easier to integrate with ERP, CRM, warehouse and payment systems and to evolve components independently.
Distributed order management and inventory services
Core OMS capabilities include distributed order management, centralized inventory services and rules-based order routing. These services evaluate sourcing options in real time and decide from which location to fulfill each line item based on stock, cost and service level goals.
Integration and middleware capabilities
A robust OMS typically offers connectors or integration hubs to link digital commerce front ends with back-end systems. Positioned as middleware, it decouples fast-changing customer experiences from more stable systems of record, enabling you to launch new channels and business models without disruptive ERP changes.
Analytics and AI-assisted optimization
Advanced OMS deployments combine transactional data with analytics and AI services – for example, to predict demand, suggest optimal fulfillment locations or flag orders that may need manual review. Over time, this helps refine business rules and improve service levels and margins.
Frequently asked questions about order management systems
What is the difference between an OMS and an ERP?
An ERP system focuses on company-wide resource planning and accounting, while an OMS is specialized in orchestrating the end-to-end order lifecycle across channels and fulfillment locations. In many B2B companies, the OMS sits between digital channels and ERP, handling omnichannel order flows and then passing summarized information to ERP.
Do small and mid-sized B2B companies need an OMS?
If you only sell through one channel and handle a limited number of orders, you may be able to manage with your e-commerce platform and ERP alone. As soon as order volume grows, channels multiply or fulfillment becomes more complex, a dedicated OMS quickly pays off through fewer errors, better customer experience and lower manual effort.
How does an OMS support omnichannel strategies?
An OMS provides a central view of orders and inventory across all channels and locations. This enables scenarios such as ship-from-store, click-and-collect, endless aisle and drop shipping, while still giving customers consistent information on availability and delivery times.
Can an OMS work with multiple e-commerce front ends?
Yes. A key benefit of a modern OMS is that it can aggregate orders from multiple web shops, customer portals, marketplaces and internal sales tools. This makes it easier to roll out new digital touchpoints without duplicating order logic in each front end.
How long does it take to implement an OMS?
Implementation timelines vary depending on the complexity of your IT landscape, processes and data quality. Many B2B organizations start with a phased approach: connecting core systems and channels first, then gradually adding advanced routing rules, new markets and more sophisticated use cases.
What should we consider when selecting an OMS vendor?
Important criteria include strong B2B capabilities, proven integrations with your existing systems, support for distributed order management, scalability, and a clear product roadmap. It is also critical to assess the vendor’s experience with projects in your industry and complexity class.
Can an OMS help reduce returns and disputes?
Yes. By improving order accuracy, providing clear confirmations and delivery information, and supporting better communication between customers and internal teams, an OMS can help reduce shipping errors, misunderstandings and the resulting returns or credit notes.
