Amazon Reserved Inventory and FC Transfer, Explained

1. What Amazon Reserved Inventory Is

Reserved inventory is stock in a fulfillment center that Amazon has set aside instead of leaving it open for new orders. It's still your inventory and it still counts toward your totals. It sits outside the Available column.

Amazon's Reserved Inventory report page says reserved units might be tied to a customer order that's shipping or set aside for extra processing.

In Q4 your reserved count climbs because orders climb. A big reserved number in November usually means orders are coming in.

2. The Reserved Reasons Amazon Lists

Amazon's report page currently gives three reasons for reserved status:

• Customer order: units reserved to fill orders, including orders waiting on payment verification
• Staging: units Amazon holds temporarily for fulfillment speed, with no action needed from you
• FC processing: units set aside for extra processing, such as checking dimensions and weight, pending investigations or pending removal orders

Older guides list FC transfer as a reserved reason. The current page treats it differently, which matters for your sales.

3. Customer Order Reserves

When a buyer places an order, Amazon reserves the unit until it ships. Then Amazon deducts it from your inventory.

Amazon says payment verification can extend order processing by as long as 21 days. If the payment can't be verified and the order gets cancelled, the units return to Available. A customer-order reserve that sits for a couple of weeks is often a payment check.

4. Staging

Staging is Amazon holding units temporarily so it can fulfill orders faster. Amazon's page says no action is required from you.

Don't open cases over staged units. Watch the count. If staged units keep moving back to Available or out the door on orders, the system is doing its job.

5. FC Processing

FC processing is the one to watch. Units land here when Amazon verifies item dimensions and weight, runs an investigation or processes a removal order you created.

Amazon says it will notify you if any action is required. Check your Seller Central messages and Account Health page when FC processing counts grow, especially on a SKU with an open complaint. If you created a removal order, the units sitting there is expected. Amazon removal orders covers that flow.

6. What FC Transfer Really Means

FC transfer is Amazon moving your units from one fulfillment center to another. Amazon's page says that if your inventory is being shipped to another fulfillment center, it's still available for purchase.

You'll see transfers right after receiving. Amazon's shipment tracking page says received units may move to fulfillment centers closer to customers and become Prime eligible once they're stored at the final one. It puts that at 6 to 15 days after receipt and says units may stay reserved longer when transfers are delayed.

A listing with units in transfer can still take orders. Buyers may see a later delivery date until the units are stowed. If receiving looks slow, the stuck in receiving guide covers the timelines.

7. How Reserved Fits Your Totals

Amazon's page gives the math. For a SKU in a shipment sent to a fulfillment center, your total units equal On-Hand quantity plus Unsellable plus Reserved plus Inbound.

Reserved isn't counted in On-Hand or Unsellable. If you reconcile by adding only Available and Unsellable, you'll think units disappeared when they're sitting in Reserved. Add all four before you file anything.

"So if you haven't been doing it in the past, make sure to track your inventory, to your inventory turnover, right? Understand your numbers."

The Biggest Q1 Mistakes Amazon Sellers Make

8. When Every Unit Shows Reserved

If Available hits zero because all your units are reserved, Amazon's page warns your listing may stop showing in search for a while, since no units are free for new orders.

Amazon's advice: check the reserved breakdown, send more units if you want to keep search visibility, and don't close or delete the listing. It comes back on its own once units return to Available or FC transfer status.

In Q4 this happens on fast sellers. Plan replenishment before you hit zero. I walk through how I plan restocks in the Thursday class. Save your seat here.

9. Pull the Reserved Inventory Report

The Reserved Inventory report breaks your reserved units into customer order, staging and FC processing columns by SKU, FNSKU and ASIN. Request a .csv or .txt download from the Download tab.

You can also schedule it from the Schedule tab, and the frequency you choose sets the date range. A weekly schedule during Q4 lets you spot a SKU where FC processing keeps growing.

10. When to Open a Case

Most reserved inventory clears on its own. Consider a case when:

• FC processing units on one SKU keep growing and you haven't received any notice or created a removal
• Customer-order reserves sit past the 21-day payment verification window Amazon describes
• Units vanish from your totals after you add On-Hand, Unsellable, Reserved and Inbound together

Lost or damaged units in the warehouse have their own claim window: 60 days from the day they were reported lost or damaged. The reimbursement claim guide covers how to file.

11. Reserved Units and Cash Flow

"So what does your inventory turnover looks like? So when you spend $1 into the business, how long does it take you to turn it into like $1.60 or $1.40 to $1.60?"

Reserved units don't stop your turnover clock. Units in transfer can still sell, and customer-order units are already sold. FC processing units are the ones that freeze cash, so watch that column on your high-dollar SKUs. The FBA cash flow trap post covers the bigger picture.
