Glossary

Amazon seller glossary.

100 core terms grouped by area. Use these definitions when reading our Academy posts or evaluating Amazon agencies that throw acronyms without context.

PPC

ACoSAdvertising Cost of Sales

ACoS is ad spend divided by attributed sales, expressed as a percentage. An ACoS of 30% means $0.30 of ad cost was incurred for every $1.00 of sales attributed to ads. Used to benchmark advertising efficiency against product margin.

Related: tacos, roas, ppc

AMCAmazon Marketing Cloud

Amazon's clean-room analytics environment where advertisers query event-level ad and conversion data with SQL. Mostly relevant at DSP scale. Access and available datasets keep expanding, so check current eligibility before planning reporting around it.

Related: dsp, new-to-brand

Auto CampaignAutomatic Targeting Campaign

A Sponsored Products campaign where Amazon picks the targets from the listing content instead of a keyword list. Matches are grouped into close match, loose match, substitutes, and complements. Its search term report is the standard discovery layer that feeds the manual campaigns.

Related: sponsored-products, match-type, negative-keyword

CPCCost Per Click

What the seller actually pays when a shopper clicks an ad. Amazon auctions are second-price-style, so the realized CPC is bounded by the bid and usually comes in below it. Rising CPC with flat conversion is the classic sign of a crowding niche.

Related: acos, ctr, match-type

CTRClick-Through Rate

Clicks divided by impressions. On Amazon, CTR shows how well the main image, title, price, and review count earn the click. A weak CTR caps ad efficiency and drags organic rank down with it, since both are built on shoppers choosing the listing.

Related: main-image, cpc, unit-session-percentage

DaypartingAd Scheduling by Time of Day

Scheduling campaigns or bid changes by time of day or day of week. Native controls are limited, so most dayparting runs through bid rules or scripts. It only pays when intraday conversion patterns are stable enough to beat the added complexity.

Related: cpc, ppc

Match TypeKeyword Match Type

Match types control how closely a shopper's search must match a bidded keyword. Broad match reaches related searches in any order and phrase match requires the phrase to appear. Exact match allows only the keyword and close variants, trading reach for control over relevance and CPC.

Related: negative-keyword, cpc, ppc

Negative KeywordNegative Keyword Targeting

A search term the seller excludes from ad targeting so ads stop showing for it. Negative exact blocks the term itself and negative phrase blocks any search containing it. The primary tool for cutting wasted spend surfaced by search term reports.

Related: match-type, acos, ppc

New-to-BrandNew-to-Brand Metrics

Ad metrics that split attributed orders by whether the shopper bought from the brand within the trailing year. Available for Sponsored Brands, Sponsored Display, and DSP. The closest Amazon gets to a customer-acquisition read for advertisers.

Related: sponsored-brands, sponsored-display, dsp

PPCPay-Per-Click advertising

PPC means advertisers pay only when a shopper clicks an ad. Amazon advertising (Sponsored Products, Brands, Display) is auction-based PPC. Bid management, negative keywords, search-term mining, and KPI-window discipline are the core levers of PPC efficiency.

Related: acos, tacos, sponsored-products

Product TargetingASIN & Category Targeting

Ad targeting aimed at ASINs or categories instead of search terms, so the ad shows on competitor detail pages and category placements. Used to defend own listings and to reach shoppers who are already comparing alternatives.

Related: sponsored-products, sponsored-display, asin

ROASReturn on Ad Spend

ROAS is sales divided by ad spend — the inverse of ACoS expressed as a multiple. A ROAS of 4.0 equals an ACoS of 25%. Use ROAS when comparing Amazon ads to other channels in growth conversations; use ACoS when thinking in margin terms.

Related: acos, tacos

TACoSTotal Advertising Cost of Sales

TACoS is total ad spend divided by total sales (ads + organic) for the same seller and period, expressed as a percentage. It provides total-account context, but a change does not by itself prove that advertising caused an organic-sales change.

Related: acos, roas, ppc

Top of SearchTop of Search Placement

The first row of sponsored results at the top of page one. Amazon reports its performance separately and lets sellers apply placement-level bid adjustments. It often shows the strongest click-through of any placement, at a correspondingly higher effective bid.

Related: cpc, ctr, sponsored-products

SEO

A10 AlgorithmAmazon A10 Search Algorithm

"A10" is an informal community label, not an official Amazon algorithm name or version. Amazon does not publish a stable ranking-weight formula under that name, so BFarm does not use the term as evidence that a specific seller action will change placement.

Related: cosmo, rufus, amazon-seo

Amazon PostsAmazon Posts (Brand Feed)

A free image feed for Brand Registered sellers that surfaces on detail pages and in a browsable feed. Availability has been limited to select marketplaces. Treat it as incremental discovery on top of search, with the Store as the destination.

Related: brand-store, brand-registry

Amazon SEOAmazon Search Engine Optimization

Amazon SEO is a common label for work on accurate catalog content, policy, Amazon-native query evidence, and listing discoverability. Amazon controls indexation and placement and does not publish a stable A10/COSMO weighting formula for BFarm to promise against.

Related: a10-algorithm, cosmo, rufus, a-plus-content

Amazon's ChoiceAmazon's Choice Badge

A badge Amazon attaches to one offer per search phrase. The selection criteria are not published. It correlates with strong availability, pricing, ratings, and fast delivery for that query, and it can move to a competing ASIN at any moment.

Related: organic-rank, featured-offer

Backend KeywordsGeneric Search Terms Field

The hidden keyword field in the listing editor, indexed for search but never shown to shoppers. Amazon enforces a strict length cap and ignores repetition of words already in visible copy, so it is best spent on synonyms, spellings, and use-case language the copy cannot carry.

Related: indexing, amazon-seo, product-title

Browse NodeAmazon Category Node

A node in Amazon's category tree that a product is assigned to. It determines category-page placement, the context for BSR, and in some cases which referral-fee schedule and gating rules apply. Misassigned nodes are corrected through support cases.

Related: bsr, gating, referral-fee

BSRBest Sellers Rank

The sales-based rank Amazon assigns within each category and subcategory, refreshed frequently. It reflects recent sales relative to competing ASINs in that node. It works as a trend and demand signal and stays unreliable as an absolute sales estimate.

Related: browse-node, organic-rank

COSMOAmazon COSMO algorithm

COSMO is described in Amazon Science research as a large-scale common-sense knowledge system for e-commerce. The research provides product-discovery context but does not expose a public ranking formula or prove that a particular listing edit will change placement.

Related: a10-algorithm, rufus, amazon-seo

Honeymoon PeriodNew-ASIN Ranking Window (unofficial)

An unofficial seller-community label for the idea that new ASINs get a favorable early ranking window. Amazon has never documented such a mechanic. Treat it as a working hypothesis that early sales history matters, and avoid scheduling a launch around an assumed deadline.

Related: organic-rank, a10-algorithm

IndexingKeyword Indexation

An ASIN is indexed for a keyword when it is eligible to appear in results for that search at all. Indexation is binary and precedes ranking: a listing cannot rank for a term it is not indexed for. Commonly verified by searching the ASIN together with the term.

Related: organic-rank, backend-keywords, amazon-seo

Organic RankOrganic Search Position

The position of an ASIN in unpaid results for a query. Driven primarily by sales and conversion history against that query plus listing relevance. Ad-attributed orders feed the same sales history, so launch PPC and organic rank behave as one system.

Related: indexing, a10-algorithm, search-query-performance

RufusAmazon Rufus AI shopping assistant

Rufus is Amazon's generative AI shopping assistant for product-discovery questions in Amazon experiences. Accurate, readable product information is a quality practice, not a guarantee that a listing will be selected, cited, indexed, or ranked by Rufus.

Related: cosmo, a10-algorithm

Search SuggestionsAmazon Autocomplete

The query completions Amazon offers as a shopper types. They reflect real search demand and its exact phrasing, which makes them a fast source of keyword variants. Suggestions differ by marketplace and shift with season.

Related: backend-keywords, organic-rank

SQPSearch Query Performance

The Brand Analytics report that shows, per search query, the funnel from impressions to clicks, cart adds, and purchases, both for the whole market and for the brand's own share of it. The primary first-party dataset for deciding which keywords deserve budget.

Related: organic-rank, ctr, amazon-seo

Listing

A+ ContentA+ Content (formerly Enhanced Brand Content / EBC)

A+ Content is a visual and narrative content area available to eligible sellers. Available modules and eligibility are controlled by Amazon. Clear, factual content can support a listing presentation but does not guarantee conversion or ranking.

Related: brand-registry, brand-story, asin

Amazon VineAmazon Vine Review Program

Amazon's invite-only review program: sellers enroll units, and Vine reviewers receive them free and leave reviews. The only policy-compliant way to seed reviews on a new ASIN. Enrollment fees and unit caps apply and change over time.

Related: brand-registry

Brand StoreAmazon Brand Store

A free multi-page brand destination on Amazon, built with a drag-and-drop editor and reachable from the byline link and Sponsored Brands ads. The only landing surface on Amazon with no competitor placements on it.

Related: brand-registry, sponsored-brands, brand-story

Brand StoryBrand Story carousel

Brand Story is the cross-listing horizontal carousel above A+ Content for Brand Registered sellers. Shows 4-6 ASINs from the same brand for cross-sell discovery. Useful when the brand has cohesive multi-product narrative; less impactful for single-product brands.

Related: a-plus-content, brand-registry

Bullet PointsKey Product Features

The short feature lines ("About this item") on the detail page. They are indexed for search and read by both shoppers and Rufus when answering product questions, and category style guides restrict their length and content. Write each one as a benefit backed by proof. Keyword strings waste the slot.

Related: product-title, rufus, a-plus-content

Customer Q&ACustomer Questions & Answers

The question-and-answer block on the detail page, answerable by past buyers and by the brand. Unanswered questions send hesitant buyers to competitor listings, so brands should answer fast and with specifics.

Related: bullet-points, product-video

Listing HijackingASIN Hijacking

When another seller attaches to your ASIN with a counterfeit or materially different item, or takes the featured offer with an unauthorized one. Countered with Brand Registry tooling, test buys, and IP complaints backed by evidence.

Related: featured-offer, brand-registry, ip-complaint

Main ImagePrimary Listing Image

The first image, shown in search results. For most categories Amazon requires a pure white background with the product filling most of the frame. It is the single strongest driver of search CTR, and no other creative asset on the listing affects results as much.

Related: ctr, product-title

MYEManage Your Experiments

Amazon's built-in A/B testing for titles, main images, bullet points, and A+ Content. Brand Registered ASINs with enough traffic can run controlled split tests instead of before-and-after guesses. Tests run for weeks, so plan the content calendar around them.

Related: main-image, product-title, a-plus-content

Premium A+Premium A+ Content

The enhanced tier of A+ Content with larger modules, video, and interactive elements. Amazon has offered it to Brand Registered sellers meeting publication criteria. Availability terms have changed over time, so verify the current requirements before planning around it.

Related: a-plus-content, brand-registry

Product TitleListing Title

The listing headline, indexed for search and shown in results. Amazon enforces category-specific style rules (length limits and bans on promotional wording) and violations can suppress the listing outright. The strongest single relevance field on the detail page.

Related: backend-keywords, suppressed-listing, bullet-points

Product VideoDetail Page Video

Video uploaded to the listing image block and the video section of the detail page. It shows the product in use and answers fit-and-size questions before the buyer commits, which cuts expectation-driven returns.

Related: main-image, sponsored-brands-video

Suppressed ListingSearch-Suppressed Listing

A listing Amazon has removed from search because it fails content requirements, such as a missing main image or an overlong title. Fixed by supplying the missing data. Surfaced in Manage Inventory and the listing quality dashboards.

Related: product-title, main-image, stranded-inventory

Unit Session PercentageUnits per Session (Business Reports)

The Business Reports conversion metric: units ordered divided by sessions. The closest first-party stand-in for listing conversion rate. Benchmark it per ASIN against its own history, since category baselines differ too much for cross-category comparison.

Related: ctr, organic-rank

Variation FamilyParent-Child Variations

A parent ASIN grouping child ASINs that differ by attributes like size or color. It consolidates reviews and traffic onto one detail page. Abusing variations to merge unrelated products violates policy and is a common trigger for listing enforcement.

Related: asin, listing-hijacking

Virtual BundleVirtual Product Bundles

A Brand Registry feature that sells two or more existing FBA ASINs as one bundle listing without repackaging inventory. The bundle gets its own detail page and price. Availability follows the scarcest component in the bundle.

Related: asin, brand-registry, fba

Operations

Amazon DSPAmazon Demand-Side Platform

Amazon DSP is Amazon's programmatic advertising platform for eligible advertisers. It is separate from the Sponsored Ads scope BFarm publishes for its Advertising Optimization service; current access, inventory, activation, and pricing details must be verified with Amazon Ads.

Related: sponsored-display, ppc

ASINAmazon Standard Identification Number

ASIN is Amazon's unique 10-character alphanumeric identifier for each catalog item. Every product variation has its own ASIN. Used in PPC targeting, listing references, and account-level catalog management.

Related: fnsku, fba

AWDAmazon Warehousing & Distribution

Amazon's upstream bulk storage network that replenishes FBA automatically. Bulk storage rates run below FBA rates, and upstream inventory does not consume FBA capacity limits. Terms and rates change, so verify the current program pages.

Related: fba, monthly-storage-fee, ipi

Brand AnalyticsAmazon Brand Analytics (ABA)

The report hub for Brand Registered sellers: search query data, demographics, market basket, and repeat purchase behavior. First-party data that replaces guesswork about what shoppers search and buy together. SQP is its deepest report.

Related: search-query-performance, brand-registry

Brand RegistryAmazon Brand Registry

Amazon Brand Registry is the program that gives trademark holders elevated tools: A+ Content, Brand Story, Sponsored Brands ads, Brand Analytics search-term reports, and IP enforcement against hijackers. Requires registered trademark in the marketplace country.

Related: a-plus-content, brand-story, sponsored-brands

EFNEuropean Fulfillment Network

EFN is an Amazon fulfillment option for cross-border European orders from inventory stored in an enabled country. Eligibility, fees, delivery promises, and tax obligations vary; sellers should verify current Amazon and professional tax guidance for their configuration.

Related: pan-eu-fba, fba

FBAFulfillment by Amazon

FBA is the Amazon logistics service where sellers ship inventory to Amazon fulfillment centers and Amazon picks, packs, and ships orders to buyers. Enables Prime eligibility, customer-service handling, and pan-marketplace coverage in exchange for storage and pick-pack fees.

Related: fnsku, asin, pan-eu-fba

FBA LiquidationsFBA Liquidations Program

A recovery option that sells excess or returned FBA inventory to liquidators for a fraction of the sale price instead of paying for disposal. It recovers some value from stock that would otherwise be written off entirely.

Related: removal-order, aged-inventory-surcharge

FBMFulfillment by Merchant

FBM means the seller fulfills orders directly instead of using FBA. Useful for oversized items, slow movers, or brands with existing 3PL infrastructure. Loses Prime eligibility unless enrolled in Seller Fulfilled Prime (SFP).

Related: fba

FNSKUFulfillment Network Stock Keeping Unit

FNSKU is the unique barcode Amazon assigns to each FBA inventory item, distinct from the manufacturer UPC. FBA-bound inventory must be labeled with FNSKU stickers (or use the Amazon Stickerless commingled program, rarely recommended).

Related: fba, asin

IPIInventory Performance Index

Amazon's score of how efficiently an account manages FBA inventory, driven by excess stock, sell-through, and stranded inventory. Low scores can bring storage-volume limits. The thresholds change, so track the dashboard instead of remembered numbers.

Related: stranded-inventory, fba, monthly-storage-fee

Pan-EU FBAPan-European Fulfillment by Amazon

Pan-EU FBA is the Amazon program that distributes inventory across multiple EU fulfillment centers (DE, FR, IT, ES, PL, CZ) for faster delivery and reduced cross-border fees. Requires VAT registration in each storage country. Alternative is European Fulfillment Network (EFN) — single-country storage with cross-border shipping.

Related: fba, efn

Removal OrderFBA Removal Order

An instruction for Amazon to return or dispose of FBA inventory instead of storing it. The standard exit for aged stock before a surcharge date arrives. Per-unit fees apply, and processing stretches to weeks in peak season, so removals need planning well ahead of the deadline.

Related: aged-inventory-surcharge, stranded-inventory, fba

Seller CentralAmazon Seller Central

The web console where third-party sellers run their Amazon business: catalog, inventory, orders, advertising, reports, and account health. Distinct from Vendor Central, which serves first-party suppliers selling wholesale to Amazon.

Related: fba, account-health-rating

SKUStock Keeping Unit

The seller-defined identifier for an offer. Unlike the ASIN, which is catalog-level and shared, SKUs are private to the account. Deliberate SKU naming that encodes supplier, cost batch, or launch date stays readable years later, where ad-hoc names lose their meaning.

Related: asin, fnsku

Stranded InventoryStranded FBA Inventory

FBA stock sitting in fulfillment centers with no active listing selling it. Listing errors, policy takedowns, and pricing problems are the usual causes. It accrues storage fees while earning nothing, and the Stranded Inventory report lists a fix reason per SKU.

Related: suppressed-listing, ipi, removal-order

Finance

Account-Level ReserveAccount-Level Reserve (Unavailable Balance)

Funds Amazon temporarily withholds from disbursement to cover potential refunds and claims, released as orders clear their delivery and return window. The usual explanation for "sales are up but the payout is flat" in growing or newly flagged accounts.

Related: settlement, order-defect-rate

Aged Inventory SurchargeAged Inventory Surcharge (formerly Long-Term Storage Fee)

The escalating extra storage fee on FBA units stored beyond age thresholds, assessed on inventory-age snapshots. Avoided by selling through or filing removal orders before units cross a threshold: after the snapshot, the fee is already owed.

Related: monthly-storage-fee, removal-order

COGSCost of Goods Sold

The direct cost of acquiring sellable units: manufacturing plus packaging, usually quoted before freight. No Amazon report includes it, so every profit view inside Seller Central overstates margin until COGS and inbound freight are layered in externally.

Related: contribution-margin, fba-fulfillment-fee

Contribution MarginPer-Unit Contribution Margin

Revenue per unit minus all variable costs: COGS, inbound freight, Amazon fees, and ad spend. Derive ACoS targets from it, because advertising is paid for out of contribution margin. A target set from revenue alone overstates what ads can afford.

Related: cogs, acos, referral-fee

FBA Fulfillment FeeFBA Per-Unit Fulfillment Fee

The per-unit fee for FBA orders, set by size tier and outbound weight. Rate cards are revised periodically, so margin models must reference the current published schedule. A product priced against last year's card loses margin without anyone noticing.

Related: referral-fee, fba, contribution-margin

Inbound Placement FeeFBA Inbound Placement Service Fee

A fee tied to how inbound FBA shipments are distributed across Amazon's network. Sending stock to one receive point costs more per unit than splitting shipments across regions. Introduced in 2024, with options and rates that keep evolving.

Related: fba, fba-fulfillment-fee

Low-Inventory-Level FeeFBA Low-Inventory-Level Fee

A per-unit surcharge on FBA orders when an ASIN's stock runs persistently below Amazon's target days of supply. It penalizes chronic understocking, so the fix is replenishment planning. Exemptions exist for new and low-volume products.

Related: fba-fulfillment-fee, ipi, awd

Monthly Storage FeeFBA Monthly Storage Fee

The per-cubic-foot fee for FBA inventory in fulfillment centers, higher during Q4. It is charged on cubic volume, so oversized slow movers come to dominate the line even at low unit counts. The storage fee reports break it down per ASIN.

Related: aged-inventory-surcharge, ipi, fba

Referral FeeAmazon Referral Fee

The commission Amazon charges on each sale, calculated as a category-dependent percentage of the total sales price. It applies to every order regardless of fulfillment method and is usually the largest fee line after fulfillment. Rates live in the published fee schedule.

Related: fba-fulfillment-fee, browse-node, contribution-margin

Refund Administration Fee

The fee Amazon keeps from the referral fee it returns to the seller when an order is refunded. Refunds are never fee-neutral, which matters when modeling net margin in return-heavy categories.

Related: referral-fee, settlement

SettlementSettlement Report & Disbursement

The recurring statement in which Amazon nets sales, fees, refunds, and reserves, then disburses the balance. For accounting, the settlement report is the ground truth: it reflects what was actually paid out and why. The sales dashboard only reflects orders.

Related: account-level-reserve, referral-fee

Compliance

Account Health RatingAccount Health Rating (AHR)

Amazon's composite score of an account's policy compliance, shown in the Account Health dashboard and driven by violations weighted by severity and recency. Falling too low risks deactivation. The dashboard is the canonical place to track standing.

Related: order-defect-rate, plan-of-action, ip-complaint

GatingCategory & Brand Gating

Approval requirements that control who may sell restricted categories, brands, or products. Ungating typically requires invoices or brand authorization. Requirements differ by marketplace and keep changing, so the current application flow is the only reliable reference.

Related: browse-node, brand-registry

IP ComplaintIntellectual Property Complaint

A trademark, copyright, or patent infringement report filed against a listing by a rights owner or raised by Amazon's own detection. It creates an Account Health violation that generally requires a retraction from the rights owner or a successful appeal to clear.

Related: account-health-rating, listing-hijacking, plan-of-action

Late Shipment RateLate Shipment Rate (LSR)

The share of seller-fulfilled orders confirmed late against the expected dispatch date. An FBM-side metric with a published target. Sustained breaches bring listing-level and then account-level enforcement, while FBA orders are exempt because Amazon controls the handoff.

Related: valid-tracking-rate, fbm, order-defect-rate

ODROrder Defect Rate

The share of orders over a trailing window with negative feedback, an A-to-z Guarantee claim, or a chargeback. Amazon's headline seller-performance metric: exceeding the published target threatens the account regardless of sales volume.

Related: account-health-rating, late-shipment-rate, account-level-reserve

POAPlan of Action

The structured appeal document Amazon expects after a suspension or violation. It lays out the root cause, then the corrective and preventive steps. Plans that get accepted are specific and evidenced. Generic templates are routinely rejected.

Related: account-health-rating, ip-complaint

Project ZeroAmazon Project Zero

A brand-protection program that combines automated counterfeit detection with self-service removal of infringing listings by the brand itself. Access requires Brand Registry and a clean track record, and the self-service removals are audited.

Related: transparency, ip-complaint, brand-registry

Responsible PersonEU Responsible Person (GPSR)

The EU-established contact that product-safety regulation requires for many goods sold into the EU, displayed on the listing. Amazon blocks non-compliant listings in EU marketplaces, so appointing one is a launch prerequisite there. Rules differ by product type.

Related: epr, marketplace

TransparencyAmazon Transparency Program

Amazon's serialization program: each enrolled unit carries a unique code that Amazon checks at the fulfillment center, and units without valid codes are blocked. Strong counterfeit protection with a real operational cost, since every sellable unit must be labeled.

Related: listing-hijacking, brand-registry, project-zero

Valid Tracking RateValid Tracking Rate (VTR)

The share of seller-fulfilled shipments carrying valid carrier tracking. Amazon requires it above a published threshold for most categories. A low VTR suppresses seller-fulfilled offers well before it escalates into an account-level problem.

Related: late-shipment-rate, fbm

Deals

Best DealBest Deal (7-Day Deal)

The longer-format deal placement, running up to a week with a deal badge. Higher fee and quantity commitment than a Lightning Deal in exchange for sustained visibility. Deal names and formats have shifted over the years, so check the current deals dashboard.

Related: lightning-deal, prime-exclusive-discount

Brand Tailored PromotionBrand Tailored Promotions

Targeted discounts for the brand's own shopper audiences, such as cart abandoners and repeat customers. Built on Brand Registry audience segments. One of the few remarketing levers native to Seller Central.

Related: promotion, brand-registry, new-to-brand

CouponAmazon Coupons

The clip-to-save discount badge on search results and detail pages. Sellers pay a redemption fee for each clipped-and-used coupon on top of the discount itself. The badge lifts click-through, and that visibility is often worth more than the discount mechanics.

Related: ctr, promotion

Lightning Deal

A time-boxed promotion on the Deals page with a countdown and a limited claimable quantity. Requires deal-eligible ASINs and a fee per run. Used for velocity spikes at launch and for clearing inventory before fee thresholds hit.

Related: seven-day-deal, aged-inventory-surcharge

Prime Exclusive Discount

A discount shown only to Prime members, with strike-through pricing in search results. It carries no per-redemption fee, and eligibility requires meeting price and rating conditions. A common lever during Prime Day when deal slots are full.

Related: coupon, seven-day-deal

PromotionSeller Central Promotions

Seller Central promotion types such as percentage-off and social media promo codes. They run at the offer level without deal-page placement. Stacking mistakes are the classic failure: overlapping promotions can multiply discounts beyond the intended one.

Related: coupon, brand-tailored-promotion

Subscribe & Save

Amazon's subscription program for replenishable products: the buyer commits to recurring deliveries for a discount that the seller funds. It grows lifetime value for consumables and dampens rank volatility with a predictable order base.

Related: coupon, unit-session-percentage

International

EPRExtended Producer Responsibility

EU environmental rules that make the seller responsible for packaging and product waste, with per-country registration numbers. Amazon requires proof of registration for affected countries and can block sales without it. France and Germany enforce most visibly.

Related: responsible-person, vat

Global SellingAmazon Global Selling

Amazon's umbrella program for selling across its international marketplaces from one business. It bundles cross-listing tools and currency payouts, while tax registration and localization stay per-marketplace duties that no program removes.

Related: marketplace, unified-account, vat

IOSSImport One-Stop Shop

The EU scheme that lets VAT on low-value imported consignments be collected at checkout instead of at customs. For marketplace orders Amazon typically handles it as the deemed supplier. Mostly relevant to FBM sellers who send orders into the EU from outside it.

Related: vat, fbm

MarketplaceAmazon Marketplace (Country Site)

A country-level Amazon site with its own catalog, currency, fees, and seller metrics. Listings do not transfer automatically and reviews stay local. Expansion means redoing listings and compliance work for each new site.

Related: unified-account, global-selling, vat

Remote FulfillmentRemote Fulfillment with FBA (NARF)

US FBA inventory serving Canada and Mexico orders without storing stock in those countries. Slower delivery promises and per-unit fees in exchange for zero extra inventory placement. A low-risk way to test demand across North America.

Related: fba, marketplace, unified-account

Unified AccountNorth America & Europe Unified Accounts

A single Seller Central account spanning the marketplaces of a region, with one login and one subscription but per-marketplace listings and fees. Regional unified accounts are linkable into one global selling view.

Related: marketplace, global-selling, remote-fulfillment

VATValue Added Tax

The consumption tax on EU and UK sales. Storing inventory in a country generally creates a local VAT registration duty, so Pan-EU FBA multiplies filings. Amazon collects VAT on some cross-border orders under marketplace rules, and professional tax advice is the norm here.

Related: pan-eu-fba, efn, ioss
