Order Management System: the Essence

An order management system (OMS) streamlines the entire order processing cycle, from initial order intake to execution control and return management. Such solutions usually support different order fulfillment scenarios, including backorders, drop shipments, buy-online-pickup-in-store, and more.

A custom order management system helps efficiently handle complex and unique order processing flows and can provide AI-based fulfillment optimization. ScienceSoft’s success stories showcase the value of tailored ordering functionality for various industries, from ecommerce to drug manufacturing.

  • Necessary integrations: selling channels, payment gateways, an accounting system, warehouse management software, transport management software, etc.
  • Implementation time: 7–12+ months for a custom OMS.
  • Development costs: $200,000–$400,000, depending on the solution complexity. Please use our free cost calculator to estimate the budget for your case.

Order Management System: Key Features

Based on ScienceSoft’s experience with OMS projects, we have summarized fundamental features of a robust order management system.

Order processing

  • Automated multichannel order capturing (orders from online and offline sales channels are aggregated within a single interface).
  • Setup of order processing rules (e.g., automated order approval for shipment if the required number of items is in stock and the order is fully paid).
  • Template-based creation of sales orders (e.g., following a customer’s ordering call).
  • Bulk order processing (confirmation, cancellation, etc.).
  • Support of pre-orders and backorders.

Important Integrations for Order Management Software

ScienceSoft recommends integrating your OMS with the following systems to establish a cohesive ordering automation environment and speed up order processing and fulfillment:

Important integrations for OMS - ScienceSoft

  • Sales channels (a company's ecommerce website, social networks, third-party marketplaces, PoS, etc.) – to automatically aggregate omnichannel customer orders; to share up-to-date information on order status and location with customers.
  • Payment gateways (e.g., PayPal, Stripe, Amazon Pay, or a custom payment gateway) – to instantly process online customer payments.
  • CRM – to enable centralized recordkeeping of customer information and accurately plan marketing and promo activities taking into account segment-specific demand and customer behavior.
  • Accounting software / ERP – to record customer payment and invoice data in the general ledger, streamline debt collection, ensure timely and accurate revenue recognition and reporting.
  • Inventory and warehouse management software – to have real-time visibility into inventory levels; to easily expedite order picking, packing, and shipping and track the order execution progress.
  • Transportation management software – to accurately plan transport, timely pickup orders at a specified location and deliver them to customer; for facilitated tracking of order shipment progress (for companies relying on in-house order shipping).
  • Systems of shipping carriers (DHL, FedEx, UPS, etc.) – to compare shipping rates and track shipments (for companies that outsource order shipping).
  • A business intelligence tool – to facilitate the analytics and reporting of sales, customers, and order fulfillment insights.

Custom Order Management System vs. Pre-Built OMS

ScienceSoft’s consultants stress that custom development is not a "one-size-fits-all" option, but in some cases, tailor-made OMS may bring a way higher payback than a ready-made tool. Below, we provide a high-level comparison of the two to help you clearly see their strengths and limitations.

Off-the-shelf order management tool

If you deal with a moderate volume of orders and can go with non-unique UX and UI, consider platform-based development. From our experience, using low-code platforms like Microsoft Power Apps can cut the investments to build an OMS by up to 75%.

How to Develop Order Management Software

Order management software development is a way for companies to obtain a tailored solution that seamlessly automates their unique order aggregation, tracking, and fulfillment workflows. Below, ScienceSoft outlines key steps we take to build a reliable order management system:


Order management system design

Inventory system design

We collaborate closely with your stakeholders to elicit functional and non-functional requirements for an order management system and design a clear software concept. In particular, our experts provide an optimal OMS feature set, create role-specific UX and UI prototypes, design a scalable architecture for your ordering solution, and plan its integrations with the required software and hardware.




OMS implementation planning

Project planning

Our project managers define the deliverables, scope, and tailored KPIs of OMS development and estimate the resources (team, timelines, budget) required to complete the project. We also prepare a strategy and plan to mitigate any arising risks.




Development and testing

Development and QA

We write a server-side code of your OMS (including APIs), create user interfaces for the required roles (sales managers, order processing specialists, etc.), and set up secure and scalable storage for customer and order data. If you want to leverage AI-supported order processing, at this stage, our data scientists design and train ML models for demand planning and fulfillment optimization.

Our QA experts perform all necessary testing procedures in parallel with coding to fix any potential issues before production and prevent costly after-launch OMS changes.




Integration and data migration

Integration and data migration

We integrate your order management software with the required systems and conduct integration testing to enable a smooth and secure connection between the solutions. At this stage, we also migrate sales order data from your currently used OMS or spreadsheets.




Deployment and employee training

Deployment and pilot run

We configure OMS infrastructure, establish backup and recovery procedures, implement robust network security mechanisms, and set the ready solution live. Our experts deliver all necessary OMS documentation, including user tutorials and admin guides, to facilitate maintenance and streamline adoption.

Our consultants can also conduct employee training in a remote, in-person, or hybrid format to help your specialists involved in order processing quickly learn how to use the new software.
