What Is an Order Management System? 5 Best OMS Software

An Order Management System (OMS) is an online system that allows the monitoring of customers’ orders, verifies the order, updates the stock level, and maintains inventory management data in sync with other sales channels. Typically, it has the features of order entry, pricing validation, inventory allocation, payment processing, shipping, delivery tracking, invoicing, and returns management.

Businesses can receive orders for products not in stock, apply the wrong customer pricing, ignore credit risks, double-book orders, and delay order fulfillment as employees search through spreadsheets and multiple applications, without a system. All the risks are aggravated if an enterprise has more than one entity in its business.

That’s why an enterprise OMS should connect CRM, sales, contracts, inventory, procurement, warehouses, logistics, finance, and customer service within one order-to-cash workflow. Instead of merely storing transactions, it validates whether each order meets stock, pricing, credit, approval, fulfilment, and financial requirements before the business confirms its commitment to the customer.

While conducting research, we found that 95% of our businesses surveyed experienced order management problems from TrueCommerce. The operational risks brought about by order and inventory being out of sync are evident in inventory discrepancies 47%, returns and reverse-logistics issues 46%, and order-volume fluctuations 39%.

Learn about what an order management system is, its lifecycle, and the importance of various features that it contains, as well as how it compares with 5 OMS software platforms for businesses in Singapore.

What Is an Order Management System (OMS)?

An Order Management System (OMS) is software that manages a customer order from receipt to order fulfilment, delivery, invoice, payment, return, and order closure. It creates one record containing the customer’s details and all the products and quantities, the prices, the discounts, the delivery details, the payment schedule, the status of the approval, and the status of fulfilment.

A complete OMS does more than register the transaction. It checks whether the order can be processed under the company’s commercial and operational policies, including inventory availability, customer credit, contract validity, pricing authority, warehouse allocation, payment status, and delivery commitments.

An online order management system uses the same controls as orders placed over the Internet, marketplace, customer portal, mobile app, point-of-sale systems, or electronic data interchange. It sends validated info to the inventory, fulfillment and shipping, accounting, and customer-notification workflows.

For example, a healthcare distributor may receive an order from a hospital with an agreed price list, credit terms, batch requirements, and scheduled delivery window. The OMS can validate those conditions, reserve eligible stock, and send the confirmed order to the correct warehouse.

Why Is an Order Management System Important?

Order management affects revenue, margins, working capital, fulfilment costs, and customer retention. Incorrect prices can reduce profitability, unavailable inventory can result in cancellations, and delayed approvals can prevent a company from meeting contractual delivery dates.

An OMS introduces control before a commercial promise becomes an operational obligation. It can identify incomplete information, excessive discounts, insufficient inventory, overdue invoices, expired agreements, or warehouse constraints before fulfilment begins.

The platform also gives management greater visibility into order cycle time, fill rates, backorders, cancellation reasons, discount exposure, delivery performance, return rates, and revenue waiting for approval or shipment.

Rather than managing every delayed transaction individually, decision makers can identify recurring bottlenecks by entity, warehouse, channel, customer group, product, or approval stage. These insights help the company address underlying process weaknesses.

For customers, the main benefit is greater consistency. Sales and service teams can provide more reliable stock information, pricing, delivery estimates, shipment status, and return updates without repeatedly contacting other departments.

A connected platform such as ScaleOcean Atlas can extend this visibility across CRM, sales, contracts, inventory, procurement, logistics, invoicing, and finance. ScaleMind works within those workflows to surface order exceptions, stock risks, customer exposure, and margin conditions requiring attention.

How Does an Order Management System (OMS) Work? 

The first step in an OMS is to order and verify necessary information to process orders. Depending on the business model, these checks can be made on the customer account, product, price, discount, currency, tax status, delivery address, credit limit, payment status, requested date, and supporting documents.

The system will then determine whether or not it can move forward without approval or if it must be approved. A regular order is executed as is and sent to an authorized employee when the items are unavailable, it is a blocked account, or the delivery is unusual or involves an excessive discount.

After validation, the OMS allocates inventory, selects a fulfilment location, sends instructions to the warehouse, records shipping progress, updates the customer, and transfers relevant information to invoicing and accounting.

Each activity remains connected to the original transaction. Sales, warehouse, finance, logistics, and customer-service teams can therefore review the same status rather than maintaining separate records.

The workflow may continue after delivery when the customer requests an exchange, refund, repair, warranty service, or credit note. A comprehensive system keeps these post-sales transactions linked to the original order.

This traceable workflow makes it easier to identify where a transaction stopped, which employee handled it, what information changed, and whether each action followed the company’s policies.

Types of Order Management Systems

Order management system examples range from simple applications for individual sellers to enterprise platforms coordinating several entities, branches, warehouses, currencies, and sales models.

Companies must also select an appropriate deployment structure. Cloud, on-premises, and hybrid systems provide different levels of accessibility, infrastructure ownership, integration flexibility, maintenance responsibility, and security control.

1. Individual and Enterprise Systems

An individual or small-business order management system commonly focuses on entering orders, updating stock, creating invoices, preparing packing documents, and recording shipments. It may be sufficient for a seller with one entity, one warehouse, limited pricing variations, and straightforward approval requirements.

These systems are usually easier to introduce because fewer employees, processes, and integrations are involved. However, companies can outgrow them when they add sales channels, customer-specific prices, fulfilment locations, legal entities, or more complex return policies.

An enterprise order management system supports wider operational dependencies, including multi-entity ownership, contract pricing, customer credit, inventory reservations, cross-warehouse allocation, partial fulfilment, approval matrices, and consolidated reporting.

It must also handle exceptions without removing accountability. Urgent requests, unavailable products, non-standard discounts, split shipments, customer holds, and cross-border orders should follow documented workflows with appropriate permissions and escalation paths.

2. Cloud-Based Options and On-Premises

A cloud-based OMS is hosted in an external cloud environment and accessed through an internet connection. It can reduce the infrastructure maintained internally while supporting employees across offices, stores, warehouses, and regional locations.

However, companies should still assess data hosting, cybersecurity, service availability, backups, access permissions, integration architecture, and disaster-recovery procedures. Cloud deployment does not remove the need for strong data governance.

An on-premises OMS is installed on infrastructure controlled by the organisation. This model may suit companies with specialized legacy systems, strict internal policies, or technical requirements that restrict external hosting.

The organization becomes responsible for infrastructure maintenance, upgrades, resilience, security monitoring, and technical resources. A hybrid arrangement offers another option by retaining selected systems or data internally while connecting them with cloud-based applications.

Challenges of an Order Management System

An OMS does not solve all the issues of orders. Lack of data, confusion over data ownership, clunky applications, and flawed processes can all turn into inefficiencies that end up as a new interface.

1. Integration Complexity

An OMS usually exchanges information with CRM, e-commerce, marketplace, inventory, warehouse, procurement, accounting, payment, shipping, customer portal, tax, and reporting applications. Every connection introduces decisions about data ownership, field mapping, update frequency, security, and error handling.

The company should find out from the customer, product, price, inventory, shipment, invoice, and payment records which application they were created from. Without rules, two systems can update the same information in different ways, or be able to duplicate transactions.

2. Inventory Visibility Flaws

OMS needs to maintain accurate inventories, and inventory must be accurate about the products in the system to decide on fulfilment. Some of the other false availability reasons are damage, late receipts, unauthorized adjustments and partial transfers, and unrecorded returns.

This risk is multiplied in the case of multiple sales channels. Product not in our online store, sold to a key account, or quarantined for inspection or reserved for other transactions.

It should differentiate on-hand, available, reserved, committed, in-transit, damaged, consignment, and backordered inventory. One total quantity displayed can provide a misleading picture to sales teams as to what it may be able to deliver.

3. Missing Features

It may be safe to assume that some platforms are offered with minimal order entry capabilities, but may not include the control that is needed to support complicated order management. Price may not be available, credit checks or other rules for allocation, return authorization, partial fulfilment, or approval process may not exist, and multi-entity reporting may not be available.

Companies should test prospective platforms against realistic scenarios, including backorders, customer-specific prices, split deliveries, substitutions, deposits, recurring orders, credit holds, expired contracts, and cross-warehouse fulfilment.

4. Lack of Configuration

Rigid software can force users to follow workflows that do not match the organization’s sales policies or responsibilities. Employees may bypass the system when its pricing, approval, or fulfilment rules make normal work unnecessarily difficult.

For example, one entity may require finance approval for every credit order, while another only escalates customers exceeding a defined exposure. Applying the same generic rule can either delay routine orders or weaken financial control.

5. High Implementation Costs

OMS investment can include software subscriptions, infrastructure, process mapping, configuration, integration, data cleansing, migration, testing, training, change management, and post-launch support. Subscription fees alone therefore provide an incomplete cost comparison.

Expenses may increase when requirements are unclear, data quality is poor, or departments introduce major changes late in the project. Unsupported legacy applications and undocumented approval practices can also extend the implementation.

The Core Order Management System Lifecycle

The OMS lifecycle describes the stages through which an order moves, from initial submission to fulfilment, settlement, and post-sales resolution.

When these stages operate separately, employees spend more time verifying status, correcting records, and resolving exceptions. A connected lifecycle maintains one traceable relationship between customer demand, fulfilment activities, and financial outcomes.

1. Order Capture

Order capture collects transactions from websites, marketplaces, stores, customer portals, EDI connections, sales representatives, call centers, or mobile applications. The OMS standardizes these orders even when their original formats differ.

Required fields may include the customer account, product, unit of measure, quantity, currency, price, discount, tax treatment, delivery address, requested date, payment terms, sales channel, and supporting documents.

2. Payment Processing

Payment processing confirms how the customer will settle the transaction. Online orders may involve cards, digital wallets, bank transfers, deposits, payment gateways, or other electronic payment services.

The OMS should distinguish authorized, pending, partially paid, failed, refunded, and disputed transactions. Each status may require a different fulfilment or customer-service response.

3. Intelligent Routing

Intelligent routing determines where and how an order should be fulfilled. The decision may consider available inventory, customer location, warehouse capacity, delivery commitments, transport costs, product restrictions, and account priority.

A retailer may send an online transaction to the nearest store, while a distributor may choose the warehouse holding the required batch. A manufacturer may trigger procurement or production when finished goods are unavailable.

Routing rules should balance customer service with profitability. The fastest warehouse may not be the most appropriate when it causes expensive split shipments or consumes inventory reserved for strategic customers.

Within ScaleOcean Atlas, ScaleMind can identify stock risks, unusual fulfilment costs, demand patterns, and orders approaching service deadlines. Human approval can remain mandatory when decisions affect margin, credit, compliance, or key accounts.

4. Fulfilment

Fulfilment includes that segment of any process where, upon order acceptance, its successful realization in the form of a tangible or intangible delivery takes place. As far as product organizations are concerned, it can cover stock keeping, order picking, verification and checking, packing and consolidation, order staging and handing off to the logistics provider.

OMS should generate correct commands to the warehouse or fulfillment centers. The correct quantity and the per-package quantity, packing condition and date, and any instructions from the client must match order confirmations.

5. Shipping and Tracking

Shipping refers to the moment when goods leave an organization’s control and are passed to the care of a carrier, route, vehicle, drop-off point, or delivery agent. The system registers tracking numbers, shipment date or time, shipping documents, and delivery instructions.

Customers and internal employees can receive suitable status updates, including dispatch confirmation, expected arrival, failed delivery attempts, proof of delivery, or exceptions requiring action.

Each shipment should remain linked to its corresponding sales order lines. The resulting data can also be used to compare transit time, carrier cost, damage rates, failed deliveries, and service-level achievement.

6. Post-Sales Follow-Up

Post-sales follow-up includes delivery confirmation, collections, returns, exchanges, refunds, warranty claims, complaints, and customer feedback. These activities influence both customer experience and the final financial value of an order.

A single OMS provides customer-service reps the ability to see what was ordered, approved, picked, shipped, delivered, invoiced, paid, returned, or credited without additional reports from multiple departments.

Who Needs an Order Management System?

 

A company needs an OMS when its order volume or complexity can no longer be handled reliably through spreadsheets, accounting applications, e-commerce dashboards, or informal communication.

The requirement becomes stronger when order errors affect stock availability, delivery performance, margins, cash flow, or customer confidence.

According to the data our team got from Esker, Siemens Healthineers increased its automated order-processing rate from 8% to 85%, while 93% of order fields were captured correctly. The implementation illustrates how structured automation can reduce manual entry and allow customer-service teams to focus on exceptions rather than routine data processing.

The following order management system examples show which organizations are most likely to benefit from centralized order orchestration.

1. Online Sellers

Online sellers receive transactions through digital storefronts where customers expect immediate confirmation and accurate product availability. Promotions, bundles, product variations, shipping methods, and payment options can quickly make basic order processing difficult to manage.

The platform becomes more valuable when sellers add marketplaces, social-commerce channels, or third-party fulfilment providers. Central visibility allows employees to manage every transaction without switching between multiple dashboards.

2. Omnichannel and Multi-Channel Retailers

Multi-channel retailers sell through stores, websites, marketplaces, call centers, or wholesale accounts. Omnichannel retailers also allow customers to move between channels during the same purchasing or return journey.

This model creates complex fulfilment requirements. A customer may purchase online, collect from a store, exchange the product at another branch, or request delivery from inventory held at a different location.

3. High-Volume E-Commerce Brands

High-volume e-commerce brands may receive large order increases during promotions, product launches, holidays, and flash sales. Manual checks that work during ordinary periods can create severe delays during demand peaks.

Companies should test platform scalability using realistic peak volumes. The system must process incoming orders, inventory updates, allocations, fulfilment requests, documents, notifications, and integration traffic without creating long queues.

4. Businesses with Multi-Location Inventory

Companies operating multiple warehouses, stores, branches, consignment locations, or third-party facilities need to know where inventory is located and whether it can be promised.

An OMS can allocate stock according to proximity, availability, cost, customer priority, batch requirements, or delivery targets. It may also initiate transfers when another location should replenish the selected fulfilment point.

5. B2B and Wholesale Distributors

B2B distributors manage customer-specific prices, negotiated discounts, bulk quantities, credit terms, delivery schedules, purchase-order references, and approval requirements. The same product may have different commercial conditions for each customer.

An enterprise OMS can apply those conditions during order creation and identify expired price agreements, discounts outside an employee’s authority, overdue accounts, minimum quantities, or unavailable inventory.

Wholesale fulfilment may involve partial deliveries, reserved inventory, backorders, drop shipments, recurring orders, and several delivery addresses. The OMS preserves visibility across these arrangements while maintaining one customer order history.

The ScaleOcean sales system can connect customer orders with CRM, contracts, inventory, approvals, procurement, fulfilment, invoicing, and finance for distributors managing complex order-to-cash workflows.

6. High-Return Retail Sectors

Fashion, footwear, electronics, furniture, beauty, and other return-sensitive sectors require more than a basic refund function. Returned products may need to be authorized, received, inspected, classified, restocked, repaired, quarantined, or written off.

An OMS keeps the commercial and physical sides of the return connected. The refund or replacement should match the original transaction, received item, product condition, payment method, and approved policy.

Key Features an Order Management System Must Have

It’s not the system with the longest list of features that will be the most effective, but rather the one that provides the controls, information, and flexibility required by the organization’s specific order model.

In order for an OMS to function effectively, the decision-maker must be able to see how each functional area links to others. For example, knowledge of stock levels would be useless if the sales price was not included, as well as customer credit authorization, warehouse location assignment, invoicing, and handling returns of an item.

1. Real-Time Inventory Syncing

Real-Time Inventory Synchronization (RSIS) updates stock levels to the exact instant the product is either sold, received, transferred, returned, broken, spoiled, assigned, or otherwise committed or claimed.

RSIS would ensure that one sales channel is not permitted to offer a product that a separate, less sophisticated channel cannot fulfill to the customer. SRSIS should supply available-to-promise inventory levels as opposed to exact physical inventory in order to mitigate the risk of promising an order to a customer prior to its receipt.

2. Omnichannel Support

Omnichannel support means that an order, customer, item, fulfillment, or return may cross between numerous related channels. A given customer should not be a new entity every time the channel within which he interacts with the company is different.

Each OMS should preserve channel attribution to maintain a single, comprehensive customer record and help businesses compare sales, margins, fulfilment costs, service expenses, and missed opportunities across channels when evaluating the best sales management software.

3. Returns Management

Returns management controls the reverse process from a customer’s request to financial and inventory resolution. It can cover eligibility checks, authorization, shipping labels, receipt, inspection, refund, exchange, repair, and restocking.

The system should record why each product was returned and what happened after receipt. Standard reason and disposition codes support consistent processing and useful analysis.

4. Sales Channels and Support

The OMS should accept orders from every channel used by the business, including websites, marketplaces, stores, mobile applications, customer portals, sales representatives, call centers, and EDI connections.

Channel support must continue after checkout. Cancelling, changing, holding, splitting, or refunding an order should update all relevant applications correctly.

Companies should test uncommon scenarios before selection. A connector that imports ordinary orders may not support bundles, subscriptions, deposits, partial refunds, or customer-specific price agreements.

5. Customer Database

A customer database stores the information required to process and support orders. This may include contacts, addresses, tax details, price lists, credit terms, contracts, preferences, delivery instructions, and transaction histories.

B2B customers may have several branches, buyers, delivery locations, cost centers, and authorized contacts. The system should represent these relationships without creating uncontrolled duplicate records.

6. Order Entry and Routing

Order entry should make it easy to create accurate transactions while enforcing mandatory controls. Product search, quotation conversion, templates, recurring orders, and bulk uploads can reduce administrative work.

Routing directs each transaction to the correct approval or fulfilment path. Conditions may depend on value, margin, entity, branch, customer group, payment terms, product risk, or delivery commitment.

7. Real-Time Order Tracking

Real-time order tracking provides actual status for each order in terms of progression from data entry through acceptance, picking, packing, shipping, delivery, invoicing, and final goods received status.

Exception tracking is as essential as actual tracking in order to identify blocking conditions for orders in progress such as hold orders, short-stock conditions, required payment, due service level agreement expiration dates for order fulfillment, and so on. Management must be aware of these circumstances.

8. Compliance and Risk Management

Compliance capabilities help ensure that orders follow internal policies and applicable business requirements. Controls may cover customer validation, product restrictions, data access, tax treatment, documentation, and approval authority.

The system should maintain an audit trail showing who created, changed, approved, released, cancelled, or credited an order. Sensitive changes may require additional authorization.

Businesses in Singapore should also evaluate role-based access, PDPA-aligned data governance, GST processes, InvoiceNow connectivity, document retention, and local financial reporting requirements.

9. Inventory Management

While the OMS often may not take the place of an independent Inventory Management System (IMS), it will need all necessary data for a customer’s available-to-promise and order fulfillment, including quantities by SKU and location, reserved and open purchase orders, transfers, batched or serialized products, expiry dates, and material classification if applicable.

Customers with sophisticated operations may have an integration between the OMS and an external WMS, where the OMS defines what orders and parts orders should be delivered from and to whom, and where the WMS tracks the real physical process.

10. Accounting Integration

Accounting integration connects orders with invoices, taxes, payments, credit notes, accounts receivable, revenue, cost of goods sold, and financial reporting.

This reduces duplicate entry and helps finance reconcile operational events with accounting records. Changes to quantities, prices, returns, or fulfilment should follow controlled financial rules.

Software Ecosystem Comparison: OMS vs. IMS vs. CRM vs. ERP

OMS, IMS, CRM, and ERP platforms frequently exchange information, but each has a different operational purpose. Choosing the wrong system category can leave important gaps or create unnecessary duplication.

An OMS manages customer orders, an IMS manages stock, a CRM manages customer relationships, and an ERP connects wider operational and financial resources.

Comparison Area	OMS	IMS	CRM	ERP
Primary purpose	Coordinates orders from capture through fulfilment, delivery, settlement, and returns.	Tracks stock quantities, locations, movements, conditions, and replenishment.	Manages leads, opportunities, communications, and customer relationships.	Connects finance, sales, procurement, inventory, HR, production, and other resources.
Central data object	Customer order and fulfilment status.	SKU, quantity, location, and inventory movement.	Lead, contact, account, opportunity, and interaction.	Operational and financial transactions across the organization.
Order lifecycle	Provides validation, routing, allocation, fulfilment, tracking, and returns.	Updates stock when orders reserve, consume, transfer, or return goods.	May create quotations but usually does not execute warehouse fulfilment.	May include order management as one function within a broader platform.
Inventory depth	Focuses on availability, reservation, allocation, and fulfilment decisions.	Provides deeper counting, replenishment, batch, serial, transfer, and stock controls.	Usually limited unless connected to inventory or ERP software.	May include inventory, warehousing, procurement, costing, and production planning.
Customer management	Stores customer data required for pricing, ordering, delivery, and service.	Uses customer data mainly to support stock transactions and fulfilment.	Provides deeper sales-pipeline, communication, campaign, and account information.	Maintains customer master data connected to financial and operational records.
Financial capability	Transfers order, invoice, payment, refund, and credit data to finance.	May support stock valuation, landed costs, and inventory accounting data.	Tracks potential sales value but usually depends on accounting integration.	Provides ledgers, receivables, payables, tax, consolidation, and reporting.
Best use	Managing complex, high-volume, B2B, or omnichannel orders.	Improving inventory accuracy, availability, and replenishment.	Developing customer relationships and managing sales pipelines.	Connecting company-wide operations with financial governance.
Main limitation when used alone	May require CRM, ERP, accounting, or WMS integrations.	Does not always manage pricing, credit, approvals, payment, and service.	Usually cannot execute complete inventory and fulfilment processes.	Generic order functions may require configuration for specialized orchestration.

A standalone OMS may suit a company that already has established CRM, finance, and warehouse systems. It can strengthen order orchestration without requiring the company to replace every existing application.

An ERP-based OMS may be more appropriate when the company wants customer orders, inventory, procurement, contracts, invoicing, and accounting to operate within the same ecosystem.

How to Choose the Right Order Management System for Your Business

Begin by documenting how orders currently enter, move through, and leave the company. Include normal transactions and exceptions such as unavailable stock, excessive discounts, credit blocks, partial fulfilment, urgent orders, substitutions, cancelled shipments, and returns.

The selection team should involve sales, customer service, finance, inventory, warehouse, procurement, logistics, IT, compliance, and management. A platform selected by one department may transfer administrative work or operational risk to another.

Next, define measurable business outcomes, such as higher order accuracy, faster approval, fewer cancellations, improved allocation, stronger margin control, shorter fulfilment time, and reduced manual entry.

Each objective should have a baseline. Without current information about cycle times, processing errors, backorders, approval delays, fulfilment costs, and return rates, the company cannot accurately evaluate results.

Ask vendors to demonstrate realistic transactions using the organization’s requirements. The demonstration should cover pricing, validation, approval, credit, allocation, fulfilment, invoicing, returns, audit history, and integration failures.

Finally, compare total ownership costs rather than subscription fees alone. Include implementation, integration, data migration, employee training, infrastructure, internal resources, support, upgrades, and additional applications.

The best order management system is the platform that supports the company’s operating model without introducing unnecessary complexity.

Medium and large enterprises can schedule a consultation with ScaleOcean to identify whether it should initially prioritize order entry, contract pricing, stock allocation, credit controls, fulfilment, invoicing, or a broader order-to-cash transformation.
