Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Hero](/nerve-centre/overview#card-classes-explained) • **Category:** [Revenue at Risk](/nerve-centre/connectors#connectors-by-type) ## 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-channel card because it joins your live ad spend to your live inventory state. When it reads above zero, the action is immediate. | | | | ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | The advertising spend (Sponsored Products, and where applicable Sponsored Brands / Display) running on ASINs whose sellable stock is at or near zero. Money spent on clicks that cannot become orders. | | **Why it happens** | Campaigns keep running after an ASIN sells out. Amazon does not automatically pause ads when stock hits zero, so unless you have a rule or you intervene, spend continues on a dead listing. | | **Cross-channel nature** | This card joins two live signals, ad spend and inventory, to surface waste neither side shows alone. The advertising console shows spend; the inventory view shows stock; only the join reveals the leak. | | **Why it is a hero card** | It is direct, recoverable cash, usually fixable in minutes by pausing or down-budgeting the affected campaigns. The payback is immediate and unambiguous. | | **Relationship to stockouts** | Driven by the same ASINs flagged in [ASINs Stocking Out \<7 Days](/nerve-centre/kpi-cards/amazon-seller/asins-stocking-out-7-days) and detected in real time by [Ad on OOS Detected](/nerve-centre/kpi-cards/amazon-seller/ad-on-oos-detected). | | **Chart** | KPI value (spend per day at risk). | | **Unit** | Currency. | | **Time window** | `7D`. | | **Alert trigger** | `>$0`. Any spend on an out-of-stock ASIN raises the card. | | **Roles** | owner, marketing, finance | ## 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. | ASIN | Product | Stock state | Live campaign | 7D ad spend (wasted) | | ---------------------------------------------- | ------------------------- | ----------------------- | ---------------- | -------------------- | | B0XXXX1 | Grain-free dog food, 12kg | Out of stock 4 days | SP auto + manual | £186 | | B0XXXX2 | Cat scratching post | Out of stock 2 days | SP manual | £74 | | B0XXXX3 | Dog dental chews | Near zero, intermittent | SP auto | £41 | | **Ad Spend on Out-of-Stock ASINs (this card)** | | | | **£301** | ```text theme={null} 7D wasted spend = £301 Daily burn rate ≈ £43/day on clicks that cannot convert Largest leak = B0XXXX1 dog food (£186, out of stock 4 days with two live campaigns) Annualised if unaddressed ≈ £15.7k/year at this run-rate ``` 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](/nerve-centre/kpi-cards/amazon-seller/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](/nerve-centre/kpi-cards/amazon-seller/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. ## Sibling cards merchants should reference together This card is a join of ads and inventory. Read it with both sides: | Card | Why pair it with Ad Spend on Out-of-Stock ASINs | | ---------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- | | [Ad on OOS Detected](/nerve-centre/kpi-cards/amazon-seller/ad-on-oos-detected) | The real-time detection event behind this card, the moment an ad starts running on zero stock. | | [ASINs Stocking Out \<7 Days](/nerve-centre/kpi-cards/amazon-seller/asins-stocking-out-7-days) | The inventory side. Fixing the stockout is the permanent fix; pausing ads is the immediate one. | | [Revenue at Risk (live)](/nerve-centre/kpi-cards/amazon-seller/revenue-at-risk-live) | The roll-up of all live revenue-at-risk signals, of which this is one. | | [Organic vs Ad Sales Share](/nerve-centre/kpi-cards/amazon-seller/organic-vs-ad-sales-share) | Context on how dependent the account is on ad spend, which makes wasted ad spend more or less material. | | [Replenishment Recommendations](/nerve-centre/kpi-cards/amazon-seller/replenishment-recommendations) | The permanent cure: get the sold-out ASINs back in stock so the ads can convert again. | ## 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. **Timing and reporting-lag table:** | Topic | Detail | | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Ad-spend lag** | Amazon advertising spend reporting has its own lag; very recent spend may not be fully reflected for a short period. Today's figure can understate. | | **Inventory freshness** | Sellable quantity is read each sync; an ASIN that just sold out may take a short while to register as zero. | | **The join window** | The waste only exists while spend and zero stock overlap. Once you pause the ads or restock, the card falls back toward zero on the next sync. | | **FBM offers** | A seller-fulfilled offer with stock in your own warehouse may keep an ASIN buyable even if FBA is zero; the card accounts for total sellable state, not just FBA. | **Why our number may legitimately differ from a manual check:** | Reason | Direction | Why | | ---------------------------- | --------------- | --------------------------------------------------------------------------------------------------------------------------------- | | **Reporting lag on spend** | Ours can trail | Amazon's advertising spend data lags; a manual Campaign Manager check minutes later may show slightly more spend. | | **Inventory timing** | Edge cases | An ASIN flickering in and out of stock can be counted as out-of-stock for part of the window only. | | **Campaign-to-ASIN mapping** | Broad campaigns | Auto and broad-match campaigns target many ASINs; attributing the exact spend share to a single out-of-stock ASIN is an estimate. | **Cross-connector reconciliation:** | Card | Expected relationship | What causes legitimate divergence | | --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | Wasted ad spend on other channels | **Same failure mode, different platform.** Paid traffic to out-of-stock products wastes budget on any channel; the Amazon-specific version is this card. | A unified inventory feed prevents this everywhere; without one, each channel can run ads on stock another channel has already sold through. | ## 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](/nerve-centre/kpi-cards/amazon-seller/ad-on-oos-detected) for the live trigger. The permanent cure is keeping hero ASINs in stock, tracked by [ASINs Stocking Out \<7 Days](/nerve-centre/kpi-cards/amazon-seller/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. *** ### Tracked live in Vortex IQ Nerve Centre *Ad Spend on Out-of-Stock ASINs* is one of hundreds of KPI pulses Vortex IQ tracks across Amazon Seller Central and 70+ other ecommerce connectors.
