At a glance

The pause-now alert. Live advertising spend, in money per day, burning on ASINs that have no sellable stock and therefore cannot convert a single click. Every pound spent here is pure waste: the shopper clicks the ad, lands on a detail page with no buy option, and leaves. This is one of the fastest, cleanest savings available on Amazon, and it is a cross-platform card because it joins your live ad spend to your live inventory state. When it reads above zero, the action is immediate.

Calculation

Calculated automatically from your Amazon Seller Central data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A UK pet-supplies brand on FBA. Snapshot taken 14 Mar 26, looking at the trailing 7 days.
Three things to notice:
  1. This is recoverable in minutes. The fix is to pause the campaigns on the three ASINs (or set their budgets to zero) until stock returns. There is no downside, the spend buys nothing while the stock is zero. The card raises on any spend above zero precisely because the action is so cheap.
  2. The dog food is the bleed and a double problem. £186 of the £301 is one out-of-stock hero product still running two campaigns. It is wasting ad spend and losing organic rank at the same time, because a sold-out listing falls in search. Replenish it urgently (ASINs Stocking Out <7 Days) and pause its ads now.
  3. Auto campaigns are the usual culprit. Sponsored Products auto-targeting keeps spending on a sold-out ASIN because it does not know the shelf is empty. A standing rule to pause ads when stock hits zero prevents this from recurring, watch Ad on OOS Detected for the live trigger.
With £301 burnt in 7 days the card is raised (>$0). The action: pause or zero-budget the affected campaigns immediately, prioritise replenishment of the sold-out hero, and put a rule in place so ads auto-pause on future stockouts.

Reconciling against Amazon Seller Central

Where to look in Seller Central: This card has no single native equivalent, because it is a cross-signal join. To verify it manually you check two places:
Advertising: Seller Central → Advertising → Campaign Manager, for live spend per campaign and the ASINs each campaign targets. Inventory: Seller Central → Inventory → Manage Inventory / FBA Inventory, for the sellable quantity of those ASINs.
Where a campaign is spending and its targeted ASIN shows zero sellable stock, that spend is the waste this card reports. Amazon does not surface this join for you, which is exactly why the card exists.

Known limitations / merchant FAQs

Why doesn’t Amazon just pause my ads when I run out of stock? It does not do this automatically by default. Campaigns keep running, and spend continues on a detail page with no buy option, until you intervene or have a rule that pauses on zero stock. That gap is what this card catches, and it is why a standing auto-pause rule is worth setting up. Is this spend completely wasted? Effectively yes. A click on an out-of-stock listing cannot become an order, so the spend buys nothing. There is a tiny edge case where a shopper bookmarks or returns later, but for planning purposes treat it as pure waste and pause the campaigns. How fast can I recover this? Immediately. Pausing or zero-budgeting the affected campaigns stops the bleed on the next sync, and there is no downside while stock is zero. This is one of the quickest savings on Amazon, which is why the card raises on any spend above zero. Auto campaigns keep doing this. How do I stop it recurring? Set up a rule that pauses advertising on an ASIN when its sellable stock hits zero, and watch Ad on OOS Detected for the live trigger. The permanent cure is keeping hero ASINs in stock, tracked by ASINs Stocking Out <7 Days. Why does this card only show a 7-day window? Because it is an action card, not a trend card. The point is the live and recent waste you can stop today. The 7-day window captures the current burn without diluting it with old, already-resolved stockouts.
