Orders
Order management in Omnium — lifecycle, workflows, returns, click & collect, and API reference.
Orders are the core of Omnium. An order can originate from any sales channel — a webshop, POS, phone order, or B2B portal — and flow through configurable workflows that handle payment, inventory, fulfillment, and notifications automatically.
Each order follows a lifecycle defined by its order type, moving through statuses like New, InProgress, Ship, and Completed. At each status transition, workflow steps execute the business logic you've configured.
