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

How it works

How the InfiPlex Extensiv integration works

If your 3PL runs its warehouse on Extensiv, InfiPlex becomes the layer that feeds it clean, aggregated orders: every sales channel you run pulls into one InfiPlex queue, fulfillment-ready orders flow to your 3PL's Extensiv system, and shipment confirmations plus inventory levels flow back — all reconciled against a single inventory pool that also covers any channel or warehouse Extensiv itself isn't involved with.

What’s included

Everything the Extensiv integration handles for you

• Works With Your Existing 3PL

  No disruption to an Extensiv-based fulfillment relationship you already have.

• Multichannel Order Aggregation

  InfiPlex pulls orders from every sales channel into one queue before routing to your 3PL.

• Real-Time Inventory Sync

  One master pool reconciling stock at your Extensiv-run 3PL against every other location and channel.

• Distinct From InfiPlex's 3PL Connector

  This is for brands using an external Extensiv-based 3PL, not InfiPlex's own 3PL onboarding program.

• Tracking Routed Back Automatically

  Shipment confirmations from your 3PL flow back through InfiPlex to the originating channel.

• Flexible Multi-Location Routing

  Mix an Extensiv-based 3PL with your own warehouse or additional fulfillment partners.
