Description

Status rules can already trigger on Minimum and Maximum Inventory Stock, but the only available action is pausing or enabling ads. There is no way to throttle bids down as inventory tightens.

The request is an inventory-aware bid action that works like the Dayparting hourly bid adjustment, but triggered by stock cover instead of hour of day:

Calculate days of stock remaining using a configurable moving average of sales, for example 180 days

Set thresholds, for example when cover drops below 45 days, reduce bids by X percent

Support tiered steps, so bids step down further as cover shrinks

Restore bids automatically when stock is replenished

This should act on bids, not budgets. Cutting budget caps volume; cutting bids lowers acquisition cost while keeping the ads live.

Use case

A seller with a large catalog and significant logistics lead times constantly has SKUs approaching low cover. Today they work around it by building status rules that pause and resume ads at manually defined stock levels, per SKU, per campaign type. With thousands of SKUs and varying sales velocities, defining and maintaining those thresholds by hand is a continuous drain, and pausing throws away sales that could still be captured profitably.

If inventory is scarce, there is no need to keep paying full price per click. Bidding down still captures the traffic and still converts, just at a lower acquisition cost, which stretches the remaining stock further at better margin. Pausing does not achieve that, it just stops sales.
