Clear Amazon seller definitions

Amazon Seller Intelligence Glossary

A practical reference for the identifiers, financial terms, inventory states, advertising metrics and evidence labels used in Amazon seller investigations. Each definition includes the boundary NAVINES IQ keeps visible before a seller acts.

Last reviewed September 26, 2026. Definitions describe the public NAVINES IQ interpretation and do not replace Amazon documentation, account-specific guidance or professional advice.

Amazon seller intelligence

The disciplined review of seller-authorized operational evidence across sales, orders, finance, listings, pricing, inventory, FBA and other supported Amazon sources.

NAVINES IQ context: NAVINES IQ keeps marketplace, period, currency, source, freshness and availability attached to the investigation.

Seller-authorized data

Amazon data returned for a seller account after that seller deliberately authorizes an application and the required roles are available.

NAVINES IQ context: Authorization does not guarantee that every endpoint, report, field, marketplace or historical period will be available.

Marketplace context

The specific Amazon marketplace attached to a returned result, such as the United States, United Kingdom, Germany or Japan.

NAVINES IQ context: NAVINES IQ does not silently combine marketplaces or currencies when the underlying values are not directly comparable.

ASIN

Amazon Standard Identification Number, the catalog identifier Amazon assigns to a product detail-page record.

NAVINES IQ context: An ASIN identifies catalog context; it is not a substitute for the seller-specific SKU or FNSKU.

SKU

A seller-defined stock keeping unit used to identify a specific listing or inventory record in the seller's operation.

NAVINES IQ context: Exact SKU matching helps prevent unrelated products with similar titles from being joined together.

FNSKU

Amazon's fulfillment-network identifier for a seller's FBA inventory unit.

NAVINES IQ context: FNSKU context can help trace inventory condition, movements and storage evidence without confusing another seller's units.

FBA

Fulfillment by Amazon, a service in which Amazon stores inventory and fulfills eligible customer orders for a seller.

NAVINES IQ context: FBA evidence can include fulfillable, reserved, inbound, researching, aged and unfulfillable inventory states when returned.

Apply the FBA inventory review checklist

Fulfillable inventory

FBA units Amazon reports as available to fulfill customer orders within the returned inventory scope.

NAVINES IQ context: Use this quantity, not a total that includes unavailable states, when making an explicitly hypothetical stock-coverage calculation.

Reserved inventory

FBA units held for customer orders, fulfillment-center transfers or fulfillment-center processing in Amazon's returned inventory breakdown.

NAVINES IQ context: Reserved units are not automatically available stock. Inspect the returned reason and timing before assuming the units can meet new demand.

See a hypothetical days-of-stock example

Inbound inventory

FBA units in an inbound stage such as working, shipped or receiving, rather than units already reported as fulfillable.

NAVINES IQ context: Keep each returned stage explicit. Planned or arriving units should not be counted as immediately available stock without supporting evidence.

Unfulfillable inventory

FBA units Amazon reports as unable to fulfill customer orders because of their condition or another returned unfulfillable status.

NAVINES IQ context: Review the returned category and exact product before deciding on a seller-controlled action. The total alone does not establish the cause or recoverable value.

Amazon listing intelligence

A review of a seller's own listing identifiers, returned statuses, issue codes, attributes and offer context for a specific Amazon marketplace.

NAVINES IQ context: A listing-status result does not measure keyword ranking or competitor sales. NAVINES IQ reviews supported evidence without editing the listing.

Review listing buyability and missing-data checks

Amazon net proceeds

The returned Amazon-side amount after Amazon-recorded fees, refunds, reimbursements and adjustments for the relevant financial scope.

NAVINES IQ context: Amazon net proceeds are not net profit because product cost, advertising, tax and external expenses may be missing.

Work through a sales-to-proceeds reconciliation

Settlement

An Amazon financial grouping that reconciles transactions for a payout period.

NAVINES IQ context: Settlement dates and totals can differ from order dates and transaction-event dates, so the source period must remain visible.

Aged inventory

FBA inventory grouped by how long units have been stored in Amazon fulfillment centers.

NAVINES IQ context: Age buckets can support storage-pressure investigation, but monetary exposure requires seller cost and applicable fee evidence.

Stranded inventory

FBA inventory Amazon reports as lacking the expected active, buyable listing relationship.

NAVINES IQ context: The inventory and the exact listing relationship should be verified before choosing a seller-controlled resolution.

Reimbursement

An amount Amazon records to compensate a seller for a qualifying inventory or transaction event.

NAVINES IQ context: A reimbursement should be reconciled with its original event and any later reversal before drawing a financial conclusion.

ACOS

Advertising cost of sales, expressed as a percentage: (advertising spend / attributed sales) × 100, using a compatible scope and period.

NAVINES IQ context: ACOS depends on the report, attribution window, currency and returned sales definition; it is not complete profitability.

Hypothetical example: $120 spend and $600 attributed sales gives 20% ACOS. If attributed sales are zero, ACOS is undefined, not 0%.

ROAS

Return on ad spend, calculated as attributed sales divided by advertising spend for a compatible scope and period.

NAVINES IQ context: ROAS measures attributed revenue efficiency, not product margin or complete business return.

Hypothetical example: $600 attributed sales / $120 spend gives 5× ROAS. If spend is zero, ROAS is undefined; missing inputs are not zero.

Attributed sales

Sales Amazon associates with advertising activity under a specified attribution window and reporting definition.

NAVINES IQ context: Attributed sales should not be silently added to total seller sales because the datasets answer different questions.

Data freshness

The time relationship between the underlying business event, the source update, the report period and the moment the result was retrieved.

NAVINES IQ context: Freshness is source-specific. A recent order and a completed historical report may be accurate while reflecting different update times.

What-If scenario

A hypothetical calculation built from explicit seller assumptions and compatible returned evidence.

NAVINES IQ context: A What-If result is not an Amazon forecast, guarantee or actual marketplace outcome.
