AI-driven Order Management Systems (OMS), OneStock, has announced a strategic partnership with delivery management platform, Metapack, now a ShipStation Global brand.

The partnership will connect OneStock’s inventory orchestration with Metapack’s global carrier network, giving retailers a single stack from order placement through to carrier selection, label generation and branded returns.

Bringing together OneStock’s unified view of inventory, sourcing intelligence and customer promise, with Metapack’s carrier network, dynamic delivery options and AI-powered delivery analytics tools, the partnership enables retailers to make promises at checkout knowing that they can be met in execution.

“The Metapack and OneStock solutions ensure that operational reality finally matches the customer’s expectation. This is about ensuring that every promise made at the Buy button is a promise kept at the front door,” said Romulus Grigoras, CEO & Co-Founder, OneStock.

Customer promise is central to OneStock’s new brand proposition, which it launched earlier this year, and looks to support retailers in upholding shopping experience promises, from product discovery to order delivery and post-purchase.

“At any given moment – across any channel, touchpoint or interaction – these layers of promises shape, define and sustain the brand-shopper relationship,” Grigoras added. “Ultimately, promise integrity determines the difference between retention and lost revenue, and between lasting loyalty and lapsed customers.”

The combined solution with Metapack is expected to enable retailers to drive +10% increase in conversion rates at checkout through transparent, reliable delivery choices, optimised orders fulfilled via existing store networks to cut shipping costs and fewer WISMOs.

“Metapack gives enterprise retailers access to the world’s most extensive carrier network through a single integration,” says Mark Honeyben, SVP & Managing Director of Europe at ShipStation Global. “This partnership adds advanced technical capabilities that ensure every delivery promise is grounded in operational reality.”
