Run Smarter Amazon Advertising with Inventory Optimizer

AMZ Advertising helps you avoid wasting ad spend on products that are running low on stock. The feature monitors your inventory in real time and automatically pauses ads when a product is at risk then re-enables them once stock recovers. It works at the product (SKU) level, so when a product belongs to multiple campaigns, the action applies across all of them at once.

This keeps your ads relevant, protects your product ranking, and saves you from paying for clicks on items customers can’t buy. Currently available for ASC companies only.

Why should you use AMZ Advertising?

Running ads for low-stock products is a common and costly mistake. You end up paying for traffic that doesn’t convert, and once those products go out of stock, your ranking can take a hit that’s hard to recover from.

AMZ Advertising steps in before that happens. It automatically pauses ads when inventory becomes low and restores them once stock levels recover. You set the thresholds that make sense for your business, and the system takes care of the rest. And if you ever want to step in manually, you can always override any action.

How does Amazon Advertising work?

Configuring AMZ Advertising Settings

Before using the AMZ Advertising feature, the company must be connected to an Amazon Seller Central account and Amazon data must be synced into Inventory Optimizer. This allows the system to retrieve the required Amazon advertising and inventory data before ad status changes are configured or managed.

After the data sync is completed, a forecast must be run first. The forecast allows the system to calculate inventory-related data, including Days Until Stockout, so AMZ Advertising can determine which SKUs are at risk or critically low.

Once the forecast is completed, inventory thresholds can be configured directly in AMZ Advertising > Settings. Both of the following values are required:

• Max Days Until Stockout: When a SKU starts to be considered at risk
• Min Days Until Stockout: When a SKU is considered critically low

Choose your mode: 

• Auto Mode lets the system handle ad status changes for you. It monitors inventory and automatically pauses or re-enables ads based on the thresholds you set, with no manual action needed.

Changes appear in the platform first, then sync to Amazon on the next forecast run  or scheduled daily sync.

• Manual Mode gives you direct control. You choose when to pause or enable ads at the SKU level, affecting all campaigns associated with that SKU, or at the individual campaign level. 

Changes also sync to Amazon on the next forecast run or scheduled daily sync.

Default values are already filled in to get you started. You can adjust them to fit your business, then click Save Changes to save. The Min value cannot be greater than the Max value.

Inventory Forecasting and Days Until Stockout 

The system calculates a number called Days Until Stockout, an estimate of how many days your stock will last at your current sales rate. It pulls inventory data from FBA, FBM, inbound shipments, and FC transfers, then combines that with your sales velocity from the forecasting engine.

A few rules apply to this calculation:

• If your inventory is zero, Days Until Stockout is set to ∞
• If your sales velocity is zero, Days Until Stockout is also set to 0

This number is then compared against your configured thresholds to determine whether your ads should be paused or re-enabled.

Review and Manage Products

The Manage Products page gives you visibility and control over your SKUs and campaigns. For each SKU, you can see its inventory risk status, current active or paused state, the campaigns it belongs to, and key performance metrics.  

Each row also shows a Managed By System icon. This helps you understand whether the SKU or campaign is managed by Inventory Optimizer or managed directly through Amazon Seller Central.

• 🤖 Managed by Inventory Optimizer: Eligible for Auto Mode. 
• 👤 Managed via Amazon Seller Central: Managed outside the system, so Auto Mode does not apply.

Click the expand arrow on any SKU row to see all the campaigns it belongs to. From there, you can pause or enable individual campaigns without affecting others. This is useful when you want more control over a specific campaign without changing your overall setup.

In this view, you can sort and filter to quickly find what you’re looking for. Use the date range picker or quick filters such as Ineligible item(s) and Paused item(s) to narrow down the list. Click any column header to sort

History Log

To ensure transparency, every automatic or manual ad adjustment is recorded in the History Log.

Click History Logs in the top right of the table to open the log panel. You’ll see a full audit trail of all actions taken by any authorized account in your company, not just your own.

Each entry shows:

• Who made the change and when it happened
• The action type (e.g., Manual Pause, Revert Enable, ...) and a unique log ID
• Which SKUs were affected 
• A Download option to export details
• A Revert button, where available, to restore the affected SKU or campaign to its previous state

Use the Action Type and Date Range filters at the top of the panel to quickly find a specific event.

Action Center

At the top of the Manage Products page, the Action Center highlights SKUs that may need your attention, specifically for SKUs where Auto Mode is off. 

SKUs are grouped into four categories based on their current ad status and inventory level:

• Active – High Risk: Ads are still running, but stock is critically low. 
• Active – Moderate Risk: Ads are still running, but stock is getting low. 
• Paused – Moderate Risk: Ads are paused, but stock is no longer critically low. 
• Paused – Well Stocked: Ads are paused, and stock is now healthy again.

Each group shows how many SKUs are system-managed versus externally managed, along with quick Pause and Enable buttons so you can take action without leaving the page.

Email Notifications

When ad status changes occur, you’ll receive an automated email summarizing the impacted products, related campaigns.

Please note that ad changes, such as pausing or enabling SKUs and campaigns, are applied in the platform first, then synced to Amazon during the next forecast run or scheduled daily sync.

From the email, you can click through to AMZ Advertising to review the changes or manually override any action if needed.

When does the system take action?

The system monitors inventory status using Days Until Stockout, which estimates how many days of stock you have left based on recent sales activity. This value is compared against your configured thresholds to determine whether action is needed.

Each SKU falls into one of three states:

• Well Stocked: Stock is healthy. Ads can continue running normally. If ads were previously paused by the system, they can be automatically re-enabled.
• Moderate Risk: Stock is getting low and may need attention. Depending on your settings and mode, ads may be paused to reduce the risk of selling out too quickly.
• High Risk: Stock is critically low. Ads are paused to help reduce wasted ad spend and avoid promoting items that may soon be unavailable.

These checks run automatically after every forecast or at least once per day if no forecast is triggered that day.

Summary

AMZ Advertising keeps your ads aligned with your inventory automatically. Set your thresholds once, and the system can pause or re-enable ads as stock levels change.

Use Auto Mode when you want the system to manage ad status for you. Use Manual Mode or the History Log whenever you need direct control or want to review what happened and why.
