SoROOS (Sourceable Replenishment Out of Stock) is an availability metric that captures the worst kind of gap: occasions when the product could genuinely be replenished — it is sourceable — but the listing is not buyable for customers, because of a suppression, a flag, or a compliance hold rather than a true lack of stock.

What is SoROOS?

SoROOS (Sourceable Replenishment Out of Stock) is an availability metric that captures the worst kind of gap: occasions when the product could genuinely be replenished — it is sourceable — but the listing is not buyable for customers, because of a suppression, a flag, or a compliance hold rather than a true lack of stock.

The distinction is important because it identifies lost buyability rather than a stock shortage. The vendor has supply, the platform wants the product, and the customer cannot buy it. Every glance view that lands on the page in that condition is demand arriving at a closed door.

What causes a sourceable product to be unbuyable

The triggers are quality and operational flags rather than inventory: a temporary sales suspension following repeated customer complaints or a safety concern, a compliance hold pending documentation, a listing suppressed for content or policy reasons, or a buyability block applied while an issue is examined.

These events are worth tracking precisely because they are avoidable in a way that a genuine stockout is not. A supplier delay is a fact of the world; a missing certificate or an unresolved complaint pattern is a process failure — and the metric quantifies the revenue that failure costs, which is usually the argument that gets the underlying process fixed.

Reading it and closing the gap

The measurement: the share of glance views on a product where it was not available to purchase despite being replenishable. A rising figure with adequate stock on hand is a strong signal that something other than inventory is holding the listing back — and the diagnostic order is compliance documents, content issues, then quality flags.

The response pattern is consistent: identify the specific block, resolve it, and then rebuild what was lost during the outage, because a period of no sales costs ranking as well as revenue. Sellers who monitor the metric catch these windows in days; sellers who do not often discover them from a revenue drop whose cause takes another week to establish.

In practice

A vendor notices availability gaps on a well-stocked ASIN and traces them to a compliance hold: a document had expired and the listing was paused pending its renewal. The certificate is renewed, the listing returns, and the renewal date is put on a calendar with an owner — converting an outage into a process fix rather than a recurring incident.

How Harpy Media helps

Availability monitoring is part of our account work: buyability gaps separated from stock problems, the underlying flags resolved at source, and the recovery planned rather than left to chance.

SoROOS FAQ

What is SoROOS?

An availability metric measuring how often a product was not available to purchase despite being replenishable — capturing lost buyability caused by flags, holds, or suppressions rather than genuine stockouts.

What causes it?

Temporary sales suspensions after complaints, compliance holds pending documentation, listing suppressions, and buyability blocks applied during a review — all conditions in which stock exists but cannot be sold.

How is it different from an out-of-stock rate?

A stockout rate counts unavailability from lack of inventory. This metric isolates the unavailability that had nothing to do with supply — which makes it a better measure of process quality.
