Available to Promise: Making Omnichannel Inventory Reliable
Learn how to calculate reliable omnichannel ATP by combining unified inventory, reservations, future supply, capacity, and allocation rules.

An Order Management System (OMS) is a centralized system that manages the entire order lifecycle, from cart to final delivery, by integrating all sales channels and available inventory locations. It is a strategic tool for orchestrating omnichannel operations, optimizing logistics costs, and improving the customer experience. Generix Group offers a powerful and customizable OMS solution designed to address these key challenges.
An Order Management System is a technology solution designed to centralize the receipt, processing, tracking, and fulfillment of orders, regardless of the sales channel used (web, store, mobile, call center). It enables the consolidation of data related to inventory, product availability, logistics resources, and customer preferences in order to optimize delivery promises.
Unlike an ERP, which manages all company resources, or a WMS, which is dedicated to warehouse logistics execution, an OMS acts as a conductor between systems. It collects information from various business applications and uses it to orchestrate orders based on business rules, product availability, customer SLAs, and logistics priorities.
An OMS provides complete traceability for every order, from creation to final delivery. It tracks statuses in real time (being prepared, shipped, delivered, returned) and facilitates customer service through visibility into all interactions.
The OMS synchronizes orders from all channels (e-commerce websites, stores, marketplaces, etc.) and automatically assigns them to the most relevant inventory location. This orchestration makes it possible to offer customers the best delivery promise by taking lead times, costs, and preferences into account.
By integrating reverse logistics flows, the OMS simplifies product returns management, replenishment, and restocking. It also enables returned products to be reallocated according to business priorities (resale, store-to-store transfers, etc.).
An OMS provides complete traceability for every order, from creation to final delivery. It tracks statuses in real time (being prepared, shipped, delivered, returned) and facilitates customer service through visibility into all interactions.
Thanks to consolidated inventory visibility and intelligent orchestration, an OMS enables reliable delivery times, flexible fulfillment options, and accurate order tracking. This directly contributes to customer satisfaction and loyalty.
The OMS automatically selects the most efficient fulfillment location based on business rules. This helps reduce transportation costs, prevent stockouts, and optimize the use of logistics resources.
With a unified inventory approach, the OMS consolidates information from warehouses, stores, and suppliers. This real-time visibility helps anticipate stock shortages and adjust operations according to business needs.
By combining inventory, capacity, and location data, the OMS selects the fastest logistics path. It therefore improves delivery performance, even during periods of high activity or network congestion.

What is omnichannel fulfillment? Learn about this essential retail strategy, its benefits, and how it unifies inventory management and order processing across all sales channels.
Retailers operating multiple customer touchpoints (stores, websites, marketplaces) use an OMS to unify order management, pool inventory, and deliver frictionless customer journeys.
An OMS becomes essential when a company operates multiple logistics sites. It centralizes visibility, automates order allocation, and enables detailed management of shipping and distribution priorities.
Brands adopting direct-to-consumer (D2C) sales models or operating across multiple countries need an OMS to align commercial strategy with large-scale logistics operations.
An OMS is designed to integrate with existing systems. It exchanges data in real time with ERP systems (administrative management), WMS platforms (logistics operations), CRM solutions (customer management), and e-commerce platforms (orders, shopping carts, product availability).
Thanks to APIs, the OMS integrates easily into modern IT architectures. It provides customizable dashboards to monitor KPIs such as service levels, average lead times, order volumes by channel, and the causes of delays or stockouts.
The OMS solution offered by Generix enables real-time aggregation of inventory across your warehouses, stores, suppliers, and partners. It includes powerful orchestration engines to configure allocation, prioritization, and sourcing rules according to your business requirements.
Adopted by leading retail and distribution companies, the Generix OMS has helped reduce logistics costs by up to 25% and improve service levels by 15% to 30%, depending on the context. Its ability to adapt to complex environments ensures rapid deployment and controlled scalability.
Customer Promise as the Driving Force
“The primary purpose of an OMS is to optimize order management so that customers can be delivered what they want, when and where they want it, while keeping costs under control for the retailer.” Generix
This box highlights that an OMS is more than just software: it is a strategic lever for delivering on customer promises and driving performance.
Focus: Unified Inventory ≠ Simple Visibility Unified inventory is not limited to simply “seeing” where products are located: it enables the assignment of the right fulfillment location, prioritization of flows, and the use of various inventory sources (stores, warehouses, suppliers, etc.), as explained by Generix.

Good to Know: APIs and IT System Integration
A modern OMS is deployed within an open ecosystem: modular, 100% API-driven, and connected to ERP, WMS, CRM, and e-commerce platforms. This approach ensures agility and rapid integration.Generix
Yes. An OMS integrates returns management (inventory reallocation, inspection, restocking, or transfers) and enables reverse logistics to be incorporated into the overall order-delivery-return cycle. This helps reduce return costs and maintain high service levels.
