Extensiv Integration FAQs: your 3PL's warehouse system, your own multichannel OMS

The InfiPlex Extensiv integration connects an Extensiv-powered warehouse or 3PL to the InfiPlex Inventory & Order Management System. InfiPlex aggregates orders from every sales channel you run, sends fulfillment-ready orders to your Extensiv-based 3PL, and pushes the resulting tracking back out to the originating marketplace — all while managing real-time inventory sync across channels that Extensiv alone doesn't handle.

Extensiv is the rebranded name for 3PL Central, which merged with the Skubana order-management platform and other tools in 2021 and unified under the Extensiv brand in 2022. It's widely used by third-party logistics providers to run warehouse management, and by some brands directly for order routing across their own fulfillment network.

Yes — this integration connects to a warehouse or 3PL that already runs on Extensiv, whether that's your own warehouse operation or a third-party logistics provider you've contracted with. If you don't have an Extensiv-based fulfillment relationship, InfiPlex's own order and shipping workflow already covers 100+ carriers directly.

Setup is quick and simple: after you sign up, our USA-based team provisions your OMS site within 1–2 business days and links the Extensiv account using its API credentials. There's nothing to install and no developer needed.

Most sellers are live in 1–3 business days. The connection itself completes quickly; the rest of the window goes to confirming which order types route to your Extensiv-based 3PL versus other fulfillment options.

InfiPlex does. Orders from every connected channel — Amazon, Walmart, Shopify, and 130+ more — pull into the InfiPlex OMS about every 15 minutes, giving you one aggregated queue rather than connecting each channel to Extensiv independently.

Once an order is ready to ship, InfiPlex sends it to your 3PL's Extensiv system, which then handles picking, packing, and shipping according to your existing agreement and workflow with that 3PL.

Automatically — once the 3PL completes the shipment in Extensiv, the tracking number flows back through InfiPlex to whichever channel the order originally came from.

Yes — stock levels at your 3PL feed into InfiPlex's master inventory pool, reconciled against every other channel and location in real time, so a shipment from the 3PL doesn't leave your other channels overselling stock that's already committed.

Yes — InfiPlex's routing rules can send specific SKUs or order types to your Extensiv-based 3PL while other inventory ships from your own warehouse or a different 3PL, all reconciled against one inventory pool.

No, and the distinction matters. This Extensiv integration is for brands whose own fulfillment (or their 3PL's warehouse) runs on Extensiv's WMS, connecting it to InfiPlex as a fulfillment destination. InfiPlex's separate 3PL Connector program is InfiPlex's own offering for 3PLs who want to run their client brands' entire multichannel operations — sales channels, inventory, and orders — through InfiPlex itself, with each client in its own Site Area.

If you're already running Extensiv as your WMS and simply need it to receive fulfillment-ready orders from a brand's multichannel operation, this Extensiv integration is the fit. If you want to offer your client brands a full multichannel OMS — channel connections, inventory sync, and order management — under your own service, the 3PL Connector program is built for that instead.

In some setups, yes — a 3PL could run Extensiv for its own warehouse operations while also offering the 3PL Connector program to clients who want InfiPlex managing their full channel mix. Our team can help figure out which structure fits your business during onboarding.

Not directly — Extensiv is primarily a warehouse management and 3PL billing/routing platform, while InfiPlex is a multichannel order and inventory management system. Many operations use both together: Extensiv for the physical warehouse execution, InfiPlex for the channel-facing order and inventory layer.

Because InfiPlex owns the channel connections rather than Extensiv, switching to a different WMS or 3PL later doesn't require re-connecting every marketplace — only the fulfillment routing destination changes.

InfiPlex's own order routing operates independently of Extensiv's inherited Skubana order-management layer; for most setups, InfiPlex handles the multichannel routing logic while Extensiv focuses on warehouse execution, avoiding overlapping order-routing rules between the two systems.

Yes — this integration works whether Extensiv is running at a third-party 3PL fulfilling on your behalf or at a warehouse you operate directly.

InfiPlex maintains one master inventory pool, and every sale on any channel — Amazon, Shopify, or anywhere else — updates available quantities everywhere in real time, including what's reflected as available at your Extensiv-run 3PL location.

Yes — per-location buffers let you hold back a safety quantity at any warehouse or 3PL, including one running Extensiv, set independently from your other locations.

Yes — the OMS tracks stock across multiple locations, whether that's your own warehouse, an Extensiv-run 3PL, or additional 3PL partners, and routes each order to the right source based on your rules.

Stock receipts processed in Extensiv sync back to InfiPlex's inventory pool, updating availability across every connected sales channel without manual reconciliation.

Yes — InfiPlex's connection is scoped to your specific inventory and orders within your 3PL relationship, regardless of how many other brands that 3PL also serves on their own Extensiv account.

Extensiv connects on every InfiPlex plan. Basic Starter is $49.99/month with up to 2,000 SKUs at $0.50 per order; Growth Starter is $499.99/month with 10,000 SKUs and 1,000 orders included ($0.10 per additional order); Growth Pro is $999.99/month with 100,000 SKUs and 10,000 orders included ($0.05 per additional order). Full details are on the Pricing page.

Yes — your 3PL's Extensiv-related costs are between you and your 3PL as usual; InfiPlex's plan and per-order pricing are separate and cover the multichannel OMS layer.

No — Extensiv is a standard included integration. You pay your InfiPlex plan and per-order fees only.

Growth packages carry a 3-month minimum commitment and Partner packages a 12-month term; Basic Starter is month-to-month. Schedule a demo and we'll walk through how InfiPlex and your Extensiv-based fulfillment fit together.
