Do Amazon Ads stop when you run out of stock? FBA, FBM, KDP and Merch
Sponsored Products and Display ads stop on their own when a product is out of stock; Sponsored Brands keeps spending. For FBA, FBM, KDP, Merch and vendors.
Short answer: yes for Sponsored Products and Sponsored Display, no for Sponsored Brands. An Amazon ad only shows when its product is in stock and holds the featured offer (the Buy Box). When a product runs out, its Sponsored Products and Sponsored Display ads stop showing, so they cost nothing. A Sponsored Brands ad keeps running as long as other products in it can be bought, and that is where out-of-stock money is wasted.
The rule is the same for FBA, FBM, Merch on Demand, KDP and vendors: Amazon checks whether the offer can be bought, not who ships it. Checked against Amazon's own documentation in October 2026.

The answer in two tables
What each ad type does on its own:
| Ad type | Your product is out of stock | Another seller wins the featured offer |
|---|---|---|
| Sponsored Products | Stops showing, costs nothing | Stops showing, costs nothing |
| Sponsored Display | Stops showing, costs nothing | Stops showing, costs nothing |
| Sponsored Brands | Keeps running with the other products | Keeps running and keeps spending |
What "out of stock" means for you:
| You sell as | Your ads stop when | What to watch |
|---|---|---|
| FBA seller | Your FBA stock for the SKU reaches zero | Sponsored Brands, and an FBM SKU of the same product |
| FBM seller | The quantity on your offer reaches zero | Sponsored Brands, and a quantity that does not match your shelf |
| Merch on Demand | Almost never for stock: products are printed when ordered | A design that becomes unavailable, and Sponsored Brands |
| KDP author | Almost never: ebooks have no stock, print books are printed on demand | A print book Amazon shows as unavailable, and Sponsored Brands |
| Vendor | Amazon runs out of your product | Sponsored Brands, and losing the featured offer to a seller |
FBA sellers: ads pause when your FBA stock hits zero
Your Sponsored Products and Sponsored Display ads stop on their own when the SKU has no FBA stock left, and start again after you restock. You pay nothing while they are stopped.
- When they stop. As soon as the SKU can no longer be bought. They also stop when another seller wins the featured offer on the listing.
- When they restart. When stock is back. An Amazon community manager says the return can take up to four hours.
- A campaign with one product. Amazon pauses the whole campaign when its only product runs out. With several products, only the empty one stops; the others keep running.
- The same product sold FBA and FBM. A seller's Sponsored Products ad points to a SKU, not to the ASIN. An ad on your FBA SKU stops when that SKU is empty, even if your FBM SKU still has stock. Advertise both SKUs, so the one that can be bought keeps the product visible.
Sponsored Brands does not stop the same way: see where the money leaks.
FBM sellers: ads pause when your quantity hits zero
It works exactly like FBA. When the quantity on your merchant-fulfilled offer reaches zero, the offer cannot be bought, so it cannot be the featured offer, and your Sponsored Products and Sponsored Display ads stop showing it. They restart when the quantity goes back up.
- Amazon only knows the quantity you report. If Seller Central says zero while the boxes are on your shelf, your ads stop for nothing. If it says 50 while the shelf is empty, your ads keep running and sell what you cannot ship. Keep the quantity true and the ads follow it.
- Selling the same product FBA too? Advertise both SKUs, for the reason explained in the FBA section.
- Losing the featured offer to another seller also stops your Sponsored Products and Sponsored Display ads.
Merch on Demand: printed on demand, so stock is rarely the issue
Merch products are printed when a customer orders them, so they do not run out of stock the way FBA or FBM inventory does. Your ads therefore almost never stop for stock.
They follow the same rule as every other product, though: if a product can no longer be bought (a design removed or rejected, a listing that disappears for a while), its Sponsored Products ads stop showing until it can be bought again.
Amazon does not publish a rule written for Merch; the featured offer rule applies to every Sponsored Products ad. If you run Sponsored Brands for your designs, read where the money leaks.
KDP authors: ebooks never run out, print books rarely do
Kindle ebooks have no stock, so their ads never stop for stock. Paperbacks and hardcovers are printed on demand, so they are rarely out of stock. When Amazon does show a print book as unavailable, its ads stop showing, with no impressions and no spend, and start again when the book can be bought.
KDP authors can run Sponsored Products and Sponsored Brands. Sponsored Products handles stock on its own; for Sponsored Brands, see where the money leaks.
Vendors: ads pause when Amazon runs out of your product
As a vendor, Amazon holds the stock. When Amazon runs out of your product, or another seller's offer becomes the featured offer, your Sponsored Products ads stop. Amazon's rule for vendors: "listings advertised on Sponsored Products must be eligible for the Featured Offer."
- A vendor's ad points to the ASIN, not to a SKU.
- Sponsored Brands and DSP keep delivering when you lose the featured offer, so a stockout at Amazon can send paid traffic to another seller's offer.
Sponsored Brands: where out-of-stock money is wasted
Sponsored Brands does not stop when one of its products runs out. Two cases cost money.
- One product in the ad is out of stock. Amazon drops that product from the ad, but the ad keeps running while other products in it can be bought. An Amazon community manager puts it this way: "if at least one ASIN in your product list page is in stock, the ad will continue to show." Amazon's API documentation marks a landing page invalid only once it has fewer than three eligible products. In both readings the budget keeps spending on a weaker ad, and shoppers land on a page where part of what they clicked for cannot be bought.
- Another seller wins the featured offer. In Amazon's words: "If you are no longer the Featured Offer, Sponsored Brands and DSP campaigns will continue to deliver impressions. If this happens you might spend money on Amazon Ads campaigns that are driving traffic and conversion to a product detail page where another selling partner has the Featured Offer."
What to do:
- Before a product runs out, pause the Sponsored Brands ads that feature it, or swap it for a product in stock. Turn them back on after the restock.
- Watch the products where you often lose the featured offer. Amazon recommends winning it "ideally 90% or higher."
One exception: a Sponsored Brands ad built on a Brand Store creative uses its featured products for "halting bidding for the creative when the featured ASINs are out of stock or unavailable on the store page."
Why Amazon stops the ad: the featured offer rule
The featured offer is the offer on a product page with the Add to Cart or Buy Now button, often called the Buy Box. Amazon only shows an ad for a product that holds it, and an out-of-stock product cannot hold it.
From Amazon's guide for new advertisers: "Your products need to be in stock to be the featured offer and eligible for advertising." And from the Amazon Ads FAQ: "If your product isn't the Featured Offer or is out of stock, your ad will not display."
An ad that is not displayed gets no impressions and no clicks, so there is nothing to pay, whether the ad is billed per click or per thousand impressions.
How to see that an ad stopped for stock
In the Amazon Ads console: "Ads that are not eligible are flagged in the campaign manager," next to the ad.
In the Amazon Ads API (for agencies and tools), the reason comes back with the ad's status:
| API | Field | Stock-related values |
|---|---|---|
| Sponsored Products v3 | servingStatus | OUT_OF_STOCK, NO_INVENTORY, NOT_BUYABLE, NO_PURCHASABLE_OFFER |
| Sponsored Display | servingStatus | OUT_OF_STOCK, NOT_BUYABLE, NOT_IN_BUYBOX |
| Sponsored Brands v4 (campaign) | computed status | ASIN_NOT_BUYABLE, LANDING_PAGE_NOT_AVAILABLE |
| Amazon Ads API v1 | deliveryReasons | OUT_OF_STOCK, NO_INVENTORY, NOT_BUYABLE, NOT_IN_BUYBOX, NO_PURCHASABLE_OFFER |
Amazon defines OUT_OF_STOCK as "Ad offer is out of stock" and NO_INVENTORY as
"Ad offer is ineligible because inventory was removed." Sponsored Products no longer
returns NOT_IN_BUYBOX.
Frequently asked questions
Do I pay for Amazon ads while my product is out of stock?
No for Sponsored Products and Sponsored Display: the ad is not shown, so there are no impressions or clicks to pay for. Yes for Sponsored Brands, as long as the ad keeps running with its other products.
How long do Amazon ads take to restart after a restock?
Up to four hours after the product can be bought again, according to an Amazon community manager. Sponsored Products and Sponsored Display restart on their own; there is nothing to turn back on.
Should I pause my campaigns when I run out of stock?
Not your Sponsored Products or Sponsored Display campaigns: Amazon stops those ads for you and restarts them after the restock, and a manual pause is one more thing to remember to undo. Do pause the Sponsored Brands ads that feature the product.
Does losing the Buy Box stop my Amazon ads?
Yes for Sponsored Products and Sponsored Display. No for Sponsored Brands and DSP, which keep delivering and can send paid traffic to the seller who won the Buy Box. The Buy Box is what Amazon calls the featured offer.
Does a campaign stop when one of its products runs out?
In Sponsored Products, only the ad for that product stops; the campaign keeps running its other products. The whole campaign pauses only when that product was its only one.
If I sell the same product with FBA and FBM, which ad runs?
Each SKU has its own ad. An ad on an empty FBA SKU stops even if the FBM SKU has stock, so advertise both SKUs to keep the product visible.
Can a Merch on Demand product go out of stock?
Not in the usual sense: Merch products are printed when ordered. A design can still become unavailable, for example when it is removed, and its ads then stop like any other product's.
Do ads for a KDP paperback stop when Amazon shows it as unavailable?
Yes. The rule is the same for every product: no featured offer, no ad. Kindle ebooks are never out of stock.
