Unified Inventory

Unlock your potential with unified inventory

Separate and disconnected inventory pools are a revenue blocker.  By making all inventory available on all channels, while applying the necessary controls, merchants increases sales and reduce discounts and write-offs

Why unified inventory

Turn fragmented stock into sellable opportunity

Maximize product availability

Retailers lose sales when customers see products out of stock online. If you had the item they wanted in another location but couldn’t sell it, this is lost revenue, simple as that. Unified inventory aggregates every inventory location—warehouses, DCs. stores, suppliers and goods-in-transit—into a single sellable pool, increasing online availability by up to 30% without adding any physical inventory.

Prevent overselling and underselling

Disconnected inventory creates an inaccurate picture, leading to canceled orders or missed sales. A unified real-time engine synchronizes reservations across all channels, ensuring every promise made to the customer is backed by actual, available inventory.

Control distribution by channel

But not all inventory should necessarily be visible everywhere. Intelligent and flexible segmentation lets you allocate specific inventory pools to specific channels, for example to protect flagship site inventory from marketplace demand or to enable cross-border fulfillment with store stock only, or to reserve launch products for VIP customers.

When we announce that 500 pairs of Dunks are coming out, customers will queue up outside the shops, so we need a solution to serve them within a reasonable time frame. Product availability is key because customers want to buy it, whether in-store or online. Availability is a key factor for success, and we absolutely wanted a high-performance OMS to guarantee it.

How It Works

Four intelligent capabilities, one unified stock pool

Real-time inventory engine

OneStock aggregates inventory from all physical points – warehouses, distribution centers, stores and suppliers – and updates availability in real time across every sales channel. The engine processes millions of inventory updates daily, scales to handle very high volumes of concurrent requests, and maintains 99.99% availability during peak traffic periods.

Inventory views & distribution control

You can define custom inventory views tailored to your specific channels, markets or customer segments. Determine precisely which inventory is visible and usable based on configurable rules such as item inclusion or exclusion, eligible locations, and combinations of stock types, and enable advanced distribution strategies that maximize revenue and margin.

Future inventory integration

Include goods in-transit and on purchase orders as part of your sellable pool. OneStock incorporates future inventory into the unified stock layer, allowing pre-orders and early selling with accurate delivery promises based on expected receipt dates and fulfillment rules.

Inventory segmentation by channel

Allocate defined percentages of stock to each sales channel, ensuring balanced availability and controlled order orchestration. By enforcing these channel limits in real-time as online orders are processed, store inventory is protected from being consumed by online peak demand and you can manage channel-specific launches in the confidence that the inventory is available.

Safety stock & buffer management

Apply dynamic buffers to protect operations and prevent stockouts. OneStock uses buffer stock mechanisms to offset discrepancies between virtual system stock and real physical stock. The calculation subtracts disposition, reserved and buffer stock to determine sellable quantities, ensuring you never oversell.

Marketplace expansion

Grow your marketplace presence while maintaining full control over stock exposure. OneStock acts as a central inventory hub with marketplace-specific inventory views and the ability to isolate or share stock by marketplace and highly scalable real-time inventory updates prevent overselling.
