Updated 10 February 2026 |

Order management system (OMS) integrations are vital for SaaS platforms managing multiple sales channels. As eCommerce continues to grow, OMS providers must ensure reliable connections with various marketplaces and shopping platforms to stay competitive. Moreover, these integrations help streamline processes, improving efficiency across platforms.

According to Statista, global eCommerce sales are projected to exceed $6.3 trillion in 2026. As a result, both order volumes and operational complexity are expected to increase significantly.

Impact of OMS on Operational Costs and Customer Satisfaction

Additionally, research by the National Retail Federation highlights that adopting an order management system can reduce operational costs by up to 15% and improve customer satisfaction by 16% . Thus, OMS integrations not only improve operational efficiency but also enhance customer experience.

Main Order Management Software Functions

An order management system (OMS) streamlines the process of fulfilling orders for online stores and CRMs. It supports businesses with order follow-up, data entry, stock management, inventory control, and shipping logistics. As a result, OMS simplifies complex operations and ensures smooth order fulfillment.

Order management software provides essential functions that help businesses run smoothly. Below are some of the key features that OMS offers to improve efficiency:

1. What is Multichannel Order Processing?

OMS allows businesses to aggregate orders from all sales channels into a single, unified dashboard. Therefore, businesses can manage all orders from different platforms in one place, improving operational efficiency.

2. How Does Scalable Order Processing Work?

As retailers grow, OMS systems offer scalable features that adapt to increasing demands. In this way, OMS can handle more orders and support large businesses as they expand their operations.

3. How Does Order Tagging and Search Help?

OMS software provides tools for quick search and categorization of orders across the entire database. This way, businesses can easily retrieve orders, improving accuracy and reducing time spent on order management.

4. Why Are Direct Integrations with Business Channels Important?

Direct integrations with business channels allow real-time updates to order statuses. Consequently, this enables businesses to streamline their processes across various platforms and ensures timely updates for customers.

5. What is Dropshipper Integration?

OMS can automate order fulfillment based on shipping method, channel, or facility. Thus, retailers can maximize efficiency and manage their order queues more effectively, improving overall processing speed.

The Most Important Order Management System Integrations

To unlock the full potential of your order management software, focusing on the right integrations is crucial. These integrations improve efficiency and provide added value to your customers.

Here are the 9 most important order management system integrations you should prioritize for 2025:

1. Why is ERP System Integration Important?

Integrating your OMS with ERP systems allows you to instantly update sales and stock information. As a result, you gain a clear view of your client's financials, which in turn improves decision-making and business management.

2. How Does Warehouse Management System Integration Help?

By connecting your OMS with warehouse management systems, you can manage inventory and stock levels in real-time. This, in turn, ensures clients never run out of products and improves fulfillment accuracy. Moreover, it minimizes the risk of errors in stock handling.

3. Why is Payment Gateway Integration Necessary?

Payment gateway integration is essential for managing card transactions and processing third-party payments. This ensures smooth, secure, and accurate financial transactions, which, ultimately, helps maintain customer trust and satisfaction.

4. What Role Does Tax Services Integration Play?

5. How Does POS System Integration Benefit Retailers?

POS integrations allow retailers to manage inventories and cash payments at physical stores. As a result, this feature also makes online customer data available across different platforms, creating a more cohesive experience for the customer.

6. How Can PIM System Integration Improve Product Management?

Integrating with a PIM system helps manage product data effectively. It allows for the integration of images, videos, and descriptions, which, in turn, improves the conversion rate and enhances the overall shopping experience.

7. Why Integrate Email Software with OMS?

Email software integration ensures consistent communication with large clients. By automating order updates and notifications, this integration enhances the customer experience and builds brand consistency, making the process more efficient.

8. What is the Benefit of Parcel Adaptor Integration?

This integration helps calculate shipping costs accurately and ensures that orders are sent to the right carrier. Consequently, it helps eCommerce vendors offer fair prices for customers, which is vital for customer retention and satisfaction.

9. How Does Shopping Platform Integration Improve Operations?

Connecting your OMS with shopping platforms allows seamless data flow between e-stores and the OMS. This, in turn, simplifies operations and enables clients to generate personalized reports, ultimately improving their ability to make data-driven decisions.

API-Integration

How to Connect Order Management Solution with Various Shopping Platforms?

To expand your market size and build a larger customer base through 2026, it's essential to integrate your order management system (OMS) with various eCommerce platforms. Such integrations are crucial because they enable your software to add, retrieve, delete, sync, and manage data for clients selling products online via e-stores.

To successfully connect your OMS with various shopping platforms, you must avoid the pitfalls of manual integration development. A reliable solution is to use a third-party service, such as API2Cart, which allows you to connect your software with over 60+ shopping platforms and marketplaces via a unified eCommerce API.

With API2Cart’s API methods, you can easily import orders from any sales channel, sync inventory management across platforms, create shipments, update order statuses, and generate personalized reports to track the situation on each sales channel.

Example Code for Retrieving Orders with OrderList Method

Here is an example of how to retrieve orders from an eCommerce platform using API2Cart's unified API and the order.list method. For more details, you can refer to the official OrderList method documentation.

Firstly, you can use the order.list method with the required parameters, such as the store ID, order status, and date range. This allows you to filter and retrieve only the orders that match your criteria. Moreover, the API response includes all relevant order details, such as order ID, total, customer name, and creation date.
