What This Report Covers
✅ The Inventory report returns current FBA inventory quantities for every SKU across all states: fulfillable, reserved, inbound, unsellable, researching, and future supply.
✅ Inbound quantities are split into working, shipped, and receiving stages so you can track exactly where each shipment is in the pipeline.
✅ Reserved inventory is broken down into customer orders, fulfillment center transfers, and FC processing so you can see what is holding your stock.
The Amazon FBA Inventory report returns current inventory quantities for every SKU across all states in Amazon's fulfillment network. It covers fulfillable, reserved, inbound, unsellable, researching, and future supply quantities in a single dataset.
Supported Fields
What Sellers Use This For
Available stock check. afn-fulfillable-quantity is the number that drives whether your listing is active and buyable. Pulling this into a sheet gives you a live fulfillable count per SKU without opening Seller Central.
Inbound pipeline visibility. afn-inbound-working-quantity, afn-inbound-shipped-quantity, and afn-inbound-receiving-quantity show exactly where in-transit stock sits. Add these to afn-fulfillable-quantity to project your total available inventory once shipments are checked in.
Reserved inventory breakdown. reserved_customerorders, reserved_fc-transfers, and reserved_fc-processing show what is holding your reserved stock. Units stuck in FC processing for extended periods can signal a receiving issue worth investigating.
Unsellable and researching quantities. afn-unsellable-quantity and afn-researching-quantity surface stock that Amazon has flagged. Tracking these over time shows whether unsellable quantities are growing and whether researching units are being resolved.

Frequently
Asked Questions
What is a Seller Central report?
Where does Gorilla ROI get this data?
We pull directly from Amazon's Selling Partner API. No third-party intermediaries. No manual csv exports. The data comes from Amazon's own reporting infrastructure, the same source Seller Central uses to generate your reports.
How current is the data once it's connected?
Data refreshes automatically on a regular schedule. The exact cadence varies by report type based on how frequently Amazon makes that data available through the API.
Do I need to download anything or export from Seller Central?
No. Once connected, your account data pulls automatically. There are no csv files to export, no manual steps, and no scheduled downloads to manage.
Can I pull multiple reports at the same time?
Yes. Each report maps to a separate dataset. You can pull as many as your account supports and work with them side by side.
What does the "API" column in the field table mean?
It identifies which Amazon SP-API endpoint provides that data. Different report types pull from different APIs: the Reports API, Orders API, FBA Inventory API, Product Pricing API, and others. This helps you understand the data source behind each field.
Are all fields listed on each page actually available in my account?
Field availability depends on your seller account type and the marketplaces you sell in. FBA-specific fields, for example, are not available to FBM-only accounts. The fields listed reflect what Amazon exposes through the API for that report.
What if I don't see a report I need?
Check the data-supported page for the full list of reports we pull. If the report you need is not there, contact our support team. We add reports based on seller demand.
