OMS — order management, explained term by term

The full order-management vocabulary: stock allocation, ATP, fill-rate, order routing, split shipment, distributed order management — with examples.

What this cluster covers

An OMS (Order Management System) is the brain that decides, for every order, what gets allocated, which warehouse fulfils it and in what sequence — across all channels (e-commerce, marketplace, B2B, retail). The terms below describe allocation, orchestration and fulfilment logic.

Each definition includes a concrete example and links to the Azuvio OMS module.

Stock allocation — Reserving available stock for confirmed orders by priority rules to prevent over-promising.
ATP – Available to Promise — The stock quantity that can be safely promised to a new order, accounting for on-hand stock, allocations and future inbound.
Fill rate — The percentage of customer demand fulfilled fully from stock at first delivery, without backorder — a key service-level metric.
Order orchestration — Automatically coordinating each order's lifecycle from capture to delivery, across channels and warehouses.
Order routing — The automatic decision on which warehouse or location fulfils each order, for optimal cost and delivery time.
Split shipment — Splitting one order into several separate shipments, from different warehouses or at different times.
Omnichannel fulfilment — Fulfilling orders from unified stock across all sales channels, with a consistent experience wherever the customer buys.
Distributed Order Management (DOM) — Managing orders across a distributed network of stock sources (warehouses, stores, suppliers) with centralised fulfilment decisions.
Returns / Reverse logistics — Managing the reverse goods flow — from customer back to warehouse — including inspection, restocking and refund.
Order cycle time — The total time from order placement to delivery to the customer — a direct measure of operational speed.
Perfect order rate — The percentage of orders delivered with no errors — on time, in full, undamaged and with correct documentation.
SLA-based order prioritisation — Automatically ordering orders by promised deadlines and customer importance to meet delivery commitments.
