Wayfair CastleGate · InfiPlex OMS Integration
CastleGate Integration: forward-position inventory, keep full visibility
CastleGate is Wayfair's fulfillment network — you position inventory forward, Wayfair ships it, and delivery speed sells more furniture. The catch is that stock in someone else's building still has to reconcile with everything else you sell. The InfiPlex™ OMS models CastleGate as a location: orders route to it by rule, and its inventory lives in your master pool.

How it works
How the InfiPlex CastleGate integration works
Forward-positioning inventory is a bet: you gain delivery speed on Wayfair, but the stock leaves your building and — without integration — your line of sight. InfiPlex closes that gap by treating CastleGate as a fulfillment location inside your OMS: orders route to it by rule, shipment confirmations and stock levels flow back, and CastleGate quantities reconcile against your warehouses, 3PLs, and every other sales channel in one pool.
What’s included
Everything the CastleGate integration handles for you
-
CastleGate as a Location
Forward-positioned stock is modeled inside your OMS alongside your warehouses and 3PLs — one master pool, fully reconciled.
-
Rules-Based Order Routing
Qualifying orders route to CastleGate automatically by SKU, stock, or channel; everything else follows your normal fulfillment paths.
-
Confirmations Flow Back
Shipment confirmations and stock levels pull back through InfiPlex, so channels get tracking and your records stay complete.
-
Mix With Dropship
Fast movers in CastleGate for delivery speed, long tail dropshipped from your dock — the standard strategy, run without splitting inventory truth.
-
Omnichannel Ready
Where your program terms support it, orders from other connected channels can route to CastleGate the way they route to any 3PL.
-
FBA + WFS + CastleGate
Each network is just a location here — run Amazon FBA, Walmart WFS, and CastleGate simultaneously on one reconciled pool.
