What is an OMS?
An Order Management System (OMS) is a software solution that simplifies and manages the order fulfillment process. It acts as a central hub, consolidating and organizing orders from various sales channels, including online stores, in-person transactions, and phone orders. By coordinating across all touchpoints, OMS systems enable businesses to deliver a seamless, omnichannel customer experience.
Traditional OMS challenges
In traditional retail setups, managing orders involves numerous integration points that connect different sales channels to back-office systems. These connections can be complex, requiring significant time, effort, and financial investment. As a result, inefficiencies and higher operational costs often arise.

The Omnium advantage: Cloud-Based OMS
Omnium transforms traditional order management with a modern, cloud-based OMS. Designed to integrate effortlessly with other cloud services and third-party applications, Omnium uses pre-built connectors or APIs to reduce setup time and effort. It connects essential business systems like inventory management, CRM, e-commerce platforms, and shipping providers, simplifying your operations.

Key benefits of Omnium OMS

-
Greater flexibility & scalability

Enhanced accessibility
Access Omnium from anywhere with an internet connection, supporting remote teams and multiple locations. -
Cost-effective
Omnium operates on a subscription or pay-as-you-go model, eliminating the need for significant upfront investments in hardware and infrastructure. -
Reduced in-house IT burden
Cloud providers manage maintenance, updates, and security, reducing the workload on your in-house IT teams.
