Order Management System

An order management system (OMS) is the software that receives orders from every sales channel, keeps inventory in sync across all of them, and tracks each order from checkout to delivery in one place. For an ecommerce brand selling across a storefront, marketplaces, and wholesale, the OMS is the layer that decides whether those channels behave like one operation or several disconnected ones. Jay Group runs a proprietary ecommerce order management system and client portal on top of Manhattan WMS, so brands get real-time order and inventory visibility, clean channel sync, and the reporting needed to forecast demand — without stitching updates together by hand.

Why an Order Management System Matters

Selling on more than one channel creates a coordination problem the moment it starts working. Orders arrive from different places, inventory has to be reserved against the right pool, and every platform expects to be told what shipped and what is still in stock. Handled manually, this is where oversells, delayed shipments, and mismatched tracking come from — and the pain grows with every channel and every order. An order management system solves it by being the single place orders land and the single source of truth for status and availability. The payoff is a brand that can add channels and volume without adding a proportional amount of manual reconciliation.

What Sets Jay Group's Order Management System Apart

An OMS is only as good as the fulfillment underneath it. Jay Group's order management system is not a standalone app — it sits directly on the warehouse system that actually ships your orders, which is what keeps its data honest.

Real-time order and inventory visibility

Brands see order status and live inventory in one client portal, updated from the warehouse floor rather than reconstructed after the fact. No emailing for an update, and no gap between what the portal says and what actually shipped.

One inventory truth across every channel

Through 50+ native integrations, Jay Group's OMS keeps available-to-sell inventory synced across your storefront, marketplaces, ERP, and retail EDI — so the same unit is never promised twice on two platforms. Orders route into one operation regardless of where the sale happened, and an in-house development team builds custom connections when a channel falls outside the standard set.

Reporting that supports forecasting

The system turns order and inventory history into signal: sell-through by SKU and channel, order velocity, and stock movement that let you and Jay Group's team plan replenishment and staffing ahead of demand instead of reacting to a stockout.

Fulfillment that ships at 99.9% accuracy

Every order the OMS captures feeds into the Manhattan WMS operation that picks, packs, and ships it at a 99.9% order accuracy rate — inside FDA-registered, cGMP-aligned, ISO 27001-certified, DEA-registered, and PCI-certified facilities. Visibility only matters if the fulfillment behind it is right, and here it is.

An OMS Backed by an Owned, Family-Run Operation

Software is only half the story; the operation running it is the other half. Jay Group owns and operates all four of its fulfillment centers — Lancaster, PA (headquarters), Mountville, PA, Reno, NV, and Houston, TX — rather than routing orders through an asset-light network of third-party sites it does not control. With inventory positioned across the East, West, and Central U.S., brands reach more than 90% of the country within two days, and because the warehouses run seven days a week, orders keep flowing over weekends instead of waiting for Monday — real days off delivery. The facilities are operated with sustainability in mind, powered by renewable energy and energy-efficient systems. Jay Group is a third-generation, family-owned company founded in 1965 and named to the Inc. 5000, and every client gets a dedicated account manager, so the technology comes with a real person accountable for how it performs.

Built for Multi-Channel Ecommerce Brands

The OMS supports the categories Jay Group specializes in — supplements, health and beauty, personal care, food and beverage, and medical products — across the channels those brands actually sell on. Whether an order comes from a Shopify store, a marketplace, or a wholesale purchase order, it enters the same system, draws from the same inventory, and ships under the same accuracy and compliance standards.
