UPS · InfiPlex OMS Integration

UPS Integration: your negotiated rates, one multichannel queue

If you've negotiated volume-based rates directly with UPS, you shouldn't have to give them up to run a real multichannel operation. The InfiPlex™ OMS connects your existing UPS account so orders from every sales channel flow into one queue, labels buy at your actual contracted rates, and tracking posts back automatically.

How it works

How the InfiPlex UPS integration works

Connecting your UPS account to InfiPlex means every order — regardless of which marketplace or storefront it came from — can buy a label at your actual negotiated rate, not a generic published one. InfiPlex aggregates orders from every sales channel into one queue, sends orders needing labels to your authenticated UPS 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: UPS sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to UPS, and routes orders to Your Sales Channels, Your Warehouses, Other Carriers for fulfillment.

The InfiPlex UPS sync rail: orders needing labels flow from the OMS to your authenticated UPS account, UPS returns negotiated 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.

UPS Worldship

The InfiPlex OMS also includes an integration with UPS Worldship. This will allow you to download a UPS Worldship XML file to load into your UPS Worldship software. This will allow you to use UPS Worldship to manage all of your shipping. You can then create an export file of all new orders with tracking numbers for upload back into the OMS. The tracking numbers are then sent to the appropriate marketplace or eCommerce platform.
