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 vs. Omnium

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.

Omnium transforms this with a modern, cloud-based OMS. Designed to integrate effortlessly with cloud services and third-party applications, Omnium uses pre-built connectors or APIs to reduce setup time and effort.

Traditional OMS

Many integration points, high complexity, significant investment

Omnium OMS

Pre-built connectors, cloud-native, reduced complexity
