FedEx Integration: your account rates, one multichannel queue

If you already have a FedEx account with its own rate history, you shouldn't have to abandon it to run a real multichannel operation. The InfiPlex™ OMS connects your existing FedEx account so orders from every sales channel flow into one queue, labels buy at your actual account rates, and tracking posts back automatically.

How it works

How the InfiPlex FedEx integration works

Connecting your FedEx account to InfiPlex means every order — regardless of which marketplace or storefront it came from — can buy a label at your actual contracted rate, not a generic published one. InfiPlex aggregates orders from every sales channel into one queue, sends orders needing labels to your authenticated FedEx account, and posts the resulting tracking number back to whichever channel the order came from, all while keeping inventory synced across everywhere you sell.

Flow diagram: FedEx sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to FedEx, and routes orders to Your Sales Channels, Your Warehouses, Other Carriers for fulfillment.

The InfiPlex FedEx sync rail: orders needing labels flow from the OMS to your authenticated FedEx account, FedEx returns account-specific rates and the label, and InfiPlex pushes tracking out to whichever sales channel the order came from — while inventory stays reconciled across every connected channel in one pool.
