FSI Fulfillment Integration: 3PL fulfillment, connected to every channel
FSI (Fulfillment Strategies International) provides 3PL services from its Atlanta warehouse, reaching 80% of the US within two days. The InfiPlex™ OMS aggregates every sales channel into one queue, sends fulfillment-ready orders to your FSI-managed warehouse, and keeps inventory synced everywhere else you sell.

How it works
How the InfiPlex FSI integration works
If your brand fulfills through an FSI-managed warehouse, InfiPlex becomes the layer that feeds it clean, aggregated demand: every sales channel you run pulls into one InfiPlex queue, fulfillment-ready orders flow to FSI, and shipment confirmations plus inventory levels flow back — all reconciled against a single inventory pool that also covers any channel or location FSI itself isn't involved with.
