3PL Software

The software your 3PL runs decides how accurately your orders ship

3PL Software & Fulfillment Technology 📦

3PL software is the warehouse, inventory, and order-management technology a fulfillment provider runs to receive, store, pick, pack, and ship your products — and to show you what is happening with your inventory and orders in real time. When you outsource fulfillment, you are not just renting warehouse space and labor; you are inheriting whatever systems that 3PL runs on. Jay Group runs on enterprise-grade 3PL software: Manhattan Associates WMS on the warehouse floor, a proprietary ecommerce order management system and client portal for visibility, and advanced inventory controls underneath both — operated inside facilities Jay Group owns and runs, and backed by an in-house development team rather than a vendor ticket queue.

Why Your 3PL’s Software Matters

The software your 3PL runs decides how accurately your orders ship, how fast you see a stockout coming, and how cleanly your store, marketplaces, and ERP stay in sync. Weak systems show up as oversells, inventory that drifts from what your storefront shows, orders that miss cutoffs, and month-end numbers nobody trusts. Strong systems do the opposite: they hold inventory accurate to the unit, enforce the pick-pack-ship rules that protect accuracy, and push order and stock status back to your other tools without manual exports. For a growing brand, that difference is the line between fulfillment that scales quietly in the background and fulfillment that becomes a daily fire drill.

The 3PL Software Behind Jay Group Fulfillment

Jay Group's technology is built in three connected layers, each with its own page in this section.

Manhattan WMS for warehouse execution

The warehouse runs on Manhattan Associates WMS, an enterprise warehouse management system used by some of the largest supply chains in the world and a long-standing Leader in Gartner's Magic Quadrant for WMS. It directs receiving, putaway, picking, packing, and shipping across our facilities and is what lets Jay Group hold a 99.9% order accuracy rate at high volume.

Ecommerce order management system and client portal

On top of the WMS sits Jay Group's proprietary ecommerce OMS and client portal — the layer that gives brands real-time order and inventory visibility, order status, and reporting in one place instead of emailing for updates.

Inventory control and reporting

Underneath both is advanced inventory control: lot and batch tracking, serialization, expiration-date and FIFO/FEFO handling, cycle counting, and the reporting that keeps your recorded inventory matching what is physically on the shelf.

50+ Native Integrations and an In-House Development Team

Jay Group connects to your storefront, marketplaces, ERP, and shipping tools through 50+ native integrations, so orders flow in and tracking and inventory flow back without spreadsheets in the middle. When something outside that library needs to connect — a custom ERP, a retailer’s EDI routing guide, a marketplace requirement — an in-house development team builds and maintains the connection directly. You are not waiting on a third-party software vendor to prioritize your ticket. That combination of enterprise software plus a team that can extend it is unusual at a family-owned 3PL, and it is a large part of why brands with complicated routing, EDI, or channel requirements stay.

Manhattan WMS (Enterprise Execution)

Jay Group operates on Manhattan Associates WMS, an enterprise warehouse management platform used by global supply chains. It supports high-volume operations and dependable execution.

Software Backed by an Owned, Family-Run Operation

Technology only holds up when the operation behind it is stable. Jay Group owns and operates all four of its fulfillment centers — Lancaster, PA (headquarters), Mountville, PA, Reno, NV, and Houston, TX — rather than routing your inventory through an asset-light network of third-party sites it does not control. Every facility runs the same Manhattan WMS platform, so execution follows one standard wherever your product sits, and with inventory positioned across the East, West, and Central U.S., brands reach more than 90% of the country within two days on ground shipping. Those warehouses run seven days a week — a capability of the operation, not the software — so orders keep moving over weekends instead of waiting for Monday, which cuts real days off delivery. The operation is also run with sustainability in mind, powered by renewable energy and energy-efficient facility systems. It is a third-generation, family-owned company founded in 1965 and named to the Inc. 5000 list of fastest-growing private companies, and every client gets a dedicated account manager, so a real person who knows your business stays accountable for how the technology performs.

Compliance Built Into the Software

For regulated products, the software is also a compliance tool. Jay Group operates FDA-registered, cGMP-aligned, ISO 27001-certified, DEA-registered, and PCI-certified facilities, and the WMS and inventory controls enforce the lot tracking, expiration management, and chain-of-custody records those standards require. Compliance is handled in the system of record, not in a side spreadsheet.

Industries We Serve with 3PL Software

The same technology supports supplements and nutraceuticals, health and beauty, personal care, food and beverage, medical devices, and other categories where accuracy, lot control, and channel complexity matter most — across DTC, B2B, retail, and marketplace fulfillment.
