How to Issue Refunds on Amazon: Seller Central Process for FBA and FBM

Most sellers think refunds are straightforward - buyer returns item, you click a button. That’s roughly true for FBA, where Amazon handles everything automatically. But if you’re self-fulfilling even part of your catalog, the refund process changed significantly in early 2026. The short version: for most US FBM sellers, the refund now fires before you ever see the returned product. Your recourse is paperwork after the fact.

FBA Refunds: What Amazon Handles for You

If you use Fulfillment by Amazon, refunds are almost entirely out of your hands. Amazon auto-approves return requests within their return window, provides the buyer a prepaid label, receives the item at their warehouse, and issues the refund - all without any seller action. You’ll see the final status in your FBA returns reports: sellable, unsellable, or reimbursed. That’s it.

The only time FBA refunds require your attention is when Amazon reimburses you for a lost or damaged item. Since March 2025, those reimbursements are based on manufacturing or sourcing cost - not the retail price. Run the numbers on that: if Amazon loses your $45 product that costs you $12 to source, expect roughly $12 back plus a referral fee credit. On higher-margin products, the gap between what you expect and what Amazon pays can eat a meaningful chunk of your profit. Check your reimbursement reports monthly - this is one of the places where passive sellers quietly lose money.

FBM Refunds: The 4-Day Window That Matters

Self-fulfilled orders are where refund management actually matters. As of January 26, 2026, you have 4 calendar days after receiving a return to inspect the item and issue a refund. Miss that window and Amazon auto-refunds the full amount - and your eligibility for SAFE-T claims drops to only lost-in-transit or delivery error cases.

But here’s the catch that makes the 4-day window mostly academic for US sellers.

As of February 8, 2026, prepaid return labels are mandatory for US FBM orders. Amazon generates the label through Buy Shipping. When the buyer ships the item back and the carrier scans it, one of two things happens:

1. Refund at First Scan (RFS) - for orders using Amazon’s prepaid labels (which you now must for US orders), the refund triggers automatically at the first carrier scan. No inspection window. The money is already returned before the package reaches you.

2. For returns without prepaid labels - international orders or certain exempted categories - you get the 4-day inspection window after the item arrives.

The practical implication: most US FBM sellers never get a chance to inspect. Your only path to recover money on a bad return is SAFE-T claims after the fact.

When you still have control

You can configure how aggressively Amazon auto-approves returns in Seller Central under Manage Orders. The default is auto-authorize within Amazon policy with a prepaid label. You can expand that to all returns or extend the return window. For return requests that fall outside policy, you have 24 hours to respond manually. No response means automatic authorization.

The 24-hour window is where you can still exercise judgment - but only on the authorization, not the refund amount. Once you authorize and the buyer ships with a prepaid label, RFS takes over.

How to Issue a Refund in Seller Central

When you need to issue a refund manually - either proactively or after receiving a return:

1. Go to Orders > Manage Orders and find the order by Order ID or buyer name.
2. Click Refund Order from the Action column or from within the order detail page.
3. Choose full refund or partial refund.
4. Select a refund reason from the dropdown.
5. Optionally add a memo to the buyer or to yourself.
6. Click Submit Refund.

One detail worth knowing: Amazon has a Guided Refund Workflow (GRW) for inspecting returned items. GRW walks you through grading the item’s condition, applying restocking fees where appropriate, and uploading evidence like photos of damage. If you later need to file a SAFE-T claim, having this documentation already in the system is the difference between a claim that gets approved and one that doesn’t. Use it every time you touch a return - even if you’re issuing a full refund.

Partial Refunds and Restocking Fees

Not every return deserves a full refund. If a buyer returns a product with damage they caused, missing parts, or signs of use beyond what’s reasonable, you can issue a partial refund.

Restocking fees are your main tool. For FBM orders where you manually authorize the return, you can apply a fee based on the item’s condition:

Condition	Typical Restocking Fee
Item opened but undamaged	Up to 20%
Item damaged by buyer	Up to 50%
Item not returned within 45 days	Up to 100%

Here’s the part most sellers get wrong: they apply the restocking fee and then wonder why they’re dealing with an A-to-Z claim two days later. Communicate the fee to the buyer before you issue the partial refund. A quick message explaining the deduction - with a photo if the item came back damaged - prevents most disputes. Amazon’s policy allows the deduction. Surprising buyers with it is what creates problems.

For FBA returns, Amazon handles all of this. You don’t set restocking fees on FBA orders.

Returnless Refunds: When Shipping Back Costs More Than the Item

Below about $15-$20 in product cost, the math on accepting returns usually doesn’t work. Say your product costs $8 to source. Return shipping runs $4-$8. Maybe 30% of returns come back in sellable condition. You’re spending $6 to recover $2.40 of value on average. The returnless refund saves you $3.60 per return on that product.

You can set returnless refund thresholds in Seller Central - automatically issue returnless refunds on any item under a price you choose. This makes sense when:

• The item costs less than return shipping
• The product can’t be resold (consumables, hygiene products, personalized items)
• You want to avoid negative feedback on a low-value dispute

For sellers with average order values under $20, this is usually the more cost-effective path. The counterargument is that liberal returnless refunds invite abuse - some buyers learn they can “return” items and keep them. That’s a real risk, but it’s a risk you can monitor through your return rate by ASIN. If a specific product’s return rate spikes above 10-15% after enabling returnless refunds, tighten the threshold on that ASIN.

When a Refund Goes Wrong

Two scenarios land you here: Amazon auto-refunded a customer and the amount was wrong, or a buyer returned something that wasn’t your product - wrong item, empty box, used when it should be new.

For seller-fulfilled orders, file a SAFE-T claim (Seller Assurance for E-Commerce Transactions). As of February 16, 2026, you have 30 days from the refund date - down from 60 days, so the window is tighter than it used to be. You’ll need photos of the item received, tracking confirmation, and ideally documentation from the Guided Refund Workflow. SAFE-T reimbursements aren’t guaranteed and are often capped at 50% for damage cases.

One important limitation: if you missed the 4-day refund window and Amazon auto-refunded, your SAFE-T eligibility is limited to lost-in-transit and delivery errors only. Condition disputes - “the buyer returned a different item” or “the item was heavily used” - generally require you to have processed the refund yourself within the window. This is why the 4-day window matters even though most refunds now fire automatically via RFS.

If a buyer files an A-to-Z Guarantee claim instead of using the standard return process, respond within the deadline with your documentation. The burden of proof shifts depending on whether you provided tracking and delivery confirmation.

FAQ

How long do I have to issue a refund on Amazon?

For FBM orders without prepaid labels, 4 calendar days after receiving the return (as of January 26, 2026). For orders with Amazon’s prepaid labels, the refund triggers automatically via Refund at First Scan - you don’t issue it manually. FBA refunds are handled entirely by Amazon.

Can I refuse to issue a refund on Amazon?

For FBA orders, no - Amazon handles all returns within policy automatically. For FBM orders, you can deny return requests that fall outside Amazon’s return policy (after the 30-day window, for example), but denying valid return requests risks A-to-Z claims and account health impacts. Pick your battles. A $12 dispute isn’t worth an account health ding.

What happens if a buyer returns an empty box or the wrong item?

File a SAFE-T claim with photographic evidence immediately. Document the package weight at delivery (if available), the contents, and the condition. If you used the Guided Refund Workflow during inspection, that evidence is already on file.

Do I get my Amazon referral fee back when I issue a refund?

Most of it. Amazon keeps a refund administration fee - the lesser of $5.00 or 20% of the original referral fee. On a $25 item in a category with a 15% referral fee ($3.75), they keep $0.75. It’s a fixed formula, not category-dependent. If you’re on the Individual selling plan, the $0.99 per-item fee isn’t returned either.

What is the difference between a refund and a concession?

A refund reverses the original transaction - money goes back to the buyer. A concession is a partial credit you offer proactively (without a return) to resolve a complaint, like a buyer receiving a slightly damaged item they’re willing to keep at a discount. Concessions don’t trigger a return but still appear in your financial reports.
