In omnichannel retail, there's a gap between what a retailer knows is possible and what the shopper actually sees at checkout. An order management system (OMS) might know an item is sitting in a store 20 minutes away, but the shopper still sees a generic "delivered in 3–7 business days."
That gap is expensive. It's where conversion leaks, where shipping cost climbs because the wrong carrier gets booked for the wrong origin, and where the post-purchase experience fragments the moment an order splits across locations. Retailers have spent years making fulfillment intelligent, yet the customer-facing delivery promise hasn’t kept up, and that’s where the sale is won or lost.
OneStock and Ingrid have partnered to close that gap, connecting OneStock's order orchestration to Ingrid's delivery intelligence so the promise at checkout finally reflects what the network can actually do.
Connect every layer from inventory to doorstep
The two platforms address different halves of the same problem. OneStock owns the fulfillment truth — which location, what's feasible, when it can ship. Ingrid turns that truth into the shopper experience and the carrier booking that executes it.
OneStock orchestrates fulfillment
The OMS evaluates stock, proximity, cost, and service rules across stores, warehouses, and 3PLs in real time, and commits every order to the optimal fulfillment location.
Ingrid orchestrates delivery
Ingrid takes that fulfillment decision and turns it into a delivery promise at checkout the shopper can trust — showing predicted delivery dates and the delivery options that fit the specific cart and location.
Execution matches the origin
The right carrier is booked for the actual origin of the shipment, so cost-to-serve stays in line even when orders are fulfilled from the store network — and each leg of a split shipment gets its own carrier, tracking, and communication while the shopper sees one coordinated delivery.
What it means for retailers
Connecting the OMS decision to the checkout promise moves retailers away from static carrier tables and fragmented tracking toward a fulfillment stack that earns its keep commercially. In practice, retailers can:
- Offer delivery promises based on what's actually feasible, not generic estimates
- Make ship-from-store and click & collect commercially viable at scale, not just operationally possible
- Match carrier and service to the selected fulfillment node automatically
- Improve conversion with delivery options shoppers can trust — Ingrid Checkout benchmarks show accurate, optimized delivery promises lifting conversion by 5–20%
- Reduce cost-to-serve, as OneStock's routing and Ingrid's carrier orchestration together cut split shipments and avoidable miles
- Deliver one consistent post-purchase experience across every shipment, with access to 350+ carriers through a single Ingrid integration
What the leaders say
"Retailers have spent years making fulfillment intelligent, routing every order to the right place," says Susanna Grill Erntell, CEO of Ingrid. "But the delivery promise the shopper sees at checkout hasn't kept up, and that's where the sale is won or lost. Together, Ingrid and OneStock close that gap — turning every fulfillment decision into a delivery promise that converts and builds trust with shoppers."
"This collaboration with Ingrid represents our shared commitment to pragmatic, business-solving technology," says Romulus Grigoras, CEO & Co-Founder of OneStock. "As specialists in our respective fields, we have built an interoperable stack that unifies our advanced AI-driven order management with Ingrid's delivery intelligence.”
“It turns the delivery promise into a true commercial lever and allows us to give retailers the agility to turn real-time inventory data into a powerful strategic advantage. It ensures that the promise made at the 'Buy' button is a promise kept at the front door."

FAQ
What does the OneStock and Ingrid partnership do?
It connects OneStock's Distributed Order Management System with Ingrid's delivery intelligence platform, so the delivery promise a shopper sees at checkout reflects real-time inventory and the actual fulfillment location. OneStock decides where each order ships from; Ingrid turns that into an accurate checkout promise, books the right carrier for that origin, and provides unified tracking and returns.
How does connecting an OMS to the checkout improve delivery promises?
A standalone checkout shows generic estimates from static carrier tables. When the OMS feeds the checkout, the promise is grounded in where stock actually is and which location will fulfill the order — so shoppers see delivery dates and options that are genuinely feasible rather than a guess.
Does this make ship-from-store more profitable?
Yes. Ship-from-store often stays a small share of orders because the delivery economics aren't connected to the fulfillment decision. By booking the right carrier for the store origin and presenting delivery options priced accordingly, the partnership makes store fulfillment commercially viable, not just operationally possible.
What impact can retailers expect on conversion?
Ingrid Checkout benchmarks show that accurate, optimized delivery promises can lift conversion by 5–20%. The exact result depends on the retailer's baseline checkout, catalog, and markets.
Which platforms and modules does a retailer need?
A retailer needs to be running OneStock for order management and Ingrid Checkout for the delivery promise at checkout, with Ingrid's Transport and Tracking recommended to complete carrier booking and the post-purchase experience. Ingrid provides access to 350+ carriers through a single integration.
