Oracle Order Management Cloud is an order capture and fulfillment Cloud solution that is tightly integrated with Oracle Global Order Promising Cloud. It is designed to improve order handling across the order-to-cash process. Pre-integration, centrally managed orchestration policies, global availability, and fulfillment monitoring can enable increased customer satisfaction and order profitability.

Key business benefits includes,

Centralized Order Monitoring
Centralized view of orders allows users to search for orders, view statuses, see a summary of exceptions of customer, product, or supplier, and drill into the data to view additional details.

Manage Order Exceptions
Proactively identify orders that may not meet promise dates and take corrective actions and avoid customer dissatisfaction. Prioritize back orders to maximize key fulfillment metrics.

Execute Against Predictable Order Orchestration Policies
Business users can define, implement and maintain their own fulfillment orchestration policies without the need to resort to technical programming tools decreasing systems cost and minimizing IT complexity.

Change Management
Centralized change order logic supports consistent handling of order changes and revisions across all orders reducing order errors and processing costs.
