Automated FBA, AWD & WFS Transfer Tracking
When you ship inventory to Amazon or Walmart, your warehouse count should go down automatically. Carpe Inventory IQ detects your inbound shipments and creates transfers for you — no manual data entry, no spreadsheets, no reconciliation.
The problem
You ship 5 cartons to Amazon FBA on Monday. Your warehouse now has fewer units — but your inventory system still shows the old count. Until someone manually creates a transfer or adjusts the numbers, every channel is selling against inflated stock. That gap is where oversells happen.
Carpe Inventory IQ closes that gap automatically.
How it works
The entire process is automatic once your Amazon connection is active. Here is what happens behind the scenes.
Step 1
You ship to Amazon or Walmart
You create an inbound shipment in Amazon Seller Central or Walmart Seller Center — whether that is an FBA shipment, an AWD shipment, or a WFS shipment. You pack your cartons, print your labels, and hand them to the carrier. Business as usual.
Step 2
Carpe Inventory IQ detects the shipment
Every 2 hours, Carpe Inventory IQ checks Amazon’s and Walmart’s Inbound Shipment APIs for new or updated shipments. When it finds a shipment with a status of SHIPPED or later, it reads the line items — which SKUs, how many units — and matches them to your internal inventory using your SKU aliases.
Step 3
A transfer is created automatically
For each new shipment, Carpe Inventory IQ creates a completed transfer from your primary shipping location to your FBA or AWD location. Your warehouse inventory decrements immediately. The transfer appears on your Transfers page with an Auto badge so you can distinguish it from manual transfers.
Step 4
All channels update
After the transfer, Carpe Inventory IQ syncs the updated warehouse quantity to Shopify, Amazon FBM, and Walmart. Every channel reflects the fact that those units are now at Amazon, not in your warehouse. No manual reconciliation needed.
What Carpe Inventory IQ Tracks vs. What It Doesn’t
Your Warehouse → FBA
Auto-tracked. Transfer created, warehouse decremented.
Your Warehouse → AWD
Auto-tracked. Transfer created, warehouse decremented.
Your Warehouse → WFS
Auto-tracked. Transfer created, warehouse decremented.
AWD → FBA (Amazon-internal)
Not tracked as a transfer. Amazon handles this automatically. The movement is reflected in your FBA and AWD inventory balances, which sync every 2 hours.
Prerequisites
Automated transfer tracking works out of the box once three things are in place.
Active Amazon or Walmart connection
Connected via Channels → Add Amazon or Add Walmart. This gives Carpe Inventory IQ access to your seller account and inbound shipment data. For Walmart, WFS must be enabled on the connection.
FBA, AWD, and/or WFS location
At least one location with type “FBA”, “AWD”, or “WFS” on the Locations page. This is the destination for auto-created transfers.
Primary shipping location
Your main warehouse, set as the primary shipping location in Settings → Locations. This is the source that inventory transfers out of. If not set, Carpe Inventory IQ defaults to your oldest active warehouse.
Sync schedule
FBA, AWD & WFS shipment detection: Every 2 hours
The system checks Amazon’s and Walmart’s Inbound Shipment APIs for new or updated shipments from the last 30 days. Transfers are created for any shipment with status SHIPPED or later.
Amazon orders (FBM sales): Every 5 minutes
Sales order sync runs on a separate, faster schedule because oversell prevention depends on near-real-time order processing.
FBA, AWD & WFS inventory levels: Every 2 hours
Fulfillable quantities, inbound quantities, and reserved quantities at Amazon and Walmart WFS are updated alongside the shipment check.
