OneStock
EcosystemOmnichannel OMS used by European retailers for order routing, ship-from-store, and click-and-collect workflows. Provides an API for real-time inventory visibility and order orchestration across retail networks.
OneStock is an order management system focused on omnichannel fulfillment for mid-market and enterprise retailers, with strong adoption in the European retail market. The platform connects e-commerce orders to physical store inventory, enabling ship-from-store and click-and-collect workflows that use store stock to fulfill online orders.
The core capability is real-time inventory visibility across the full retail network. OneStock aggregates inventory from stores, warehouses, and suppliers into a single view, then applies configurable routing rules to determine the optimal fulfillment source for each order. The routing engine accounts for distance, stock levels, store capacity, and delivery SLA commitments.
OneStock integrates with existing ERP, WMS, and e-commerce platforms through a REST API. The API covers order import, fulfillment source assignment, order status updates, and returns management. Retailers typically implement OneStock as a layer between their e-commerce platform and their physical operations systems.
For agents, OneStock represents the connection between a UCP checkout and a physical retail fulfillment network. When a buyer completes an agent-initiated purchase at a retailer using OneStock, the OMS determines whether to fulfill from a warehouse, a nearby store, or arrange a pickup. Agents can query order status through the OneStock API to provide buyers with fulfillment source information and estimated delivery details. The ship-from-store capability is particularly relevant for agents handling time-sensitive purchases where local inventory can deliver faster than central distribution.
Why This Matters for UCP
OneStock connects UCP-initiated orders to physical retail inventory through omnichannel OMS logic, enabling ship-from-store and click-and-collect fulfillment for European retailers and exposing APIs agents can use for order routing and status.

Integration Example
// OneStock REST API for omnichannel order orchestration.
// Agents import orders and query fulfillment source assignments.
const ONESTOCK_API = process.env.ONESTOCK_API_URL;
const token = process.env.ONESTOCK_API_TOKEN;
// Check inventory availability across the retail network
const inventory = await fetch(ONESTOCK_API + '/v1/availability', {
method: 'POST',
headers: {
Authorization: 'Bearer ' + token,
'Content-Type': 'application/json',
},
body: JSON.stringify({
items: [{ sku: 'REF-001', quantity: 1 }],
delivery_address: { zip: '75001', country: 'FR' },
delivery_type: 'home_delivery',
}),
}).then(r => r.json());
console.log('Available sources:', inventory.sources?.length);
console.log('Fastest ETA:', inventory.sources?.[0]?.estimated_delivery_date);
// Import an order into OneStock for routing
const order = await fetch(ONESTOCK_API + '/v1/orders', {
method: 'POST',
headers: {
Authorization: 'Bearer ' + token,
'Content-Type': 'application/json',
},
body: JSON.stringify({
external_ref: 'UCP-001',
channel: 'online',
items: [{ sku: 'REF-001', quantity: 1, price: 39.99, currency: 'EUR' }],
delivery_type: 'home_delivery',
recipient: { name: 'Marie Dupont', zip: '75001', country: 'FR' },
}),
}).then(r => r.json());
console.log('OneStock order:', order.id, 'Routed to:', order.fulfillment_source_ref);Category
