Everything for Amazon Sellers—in One Base.

The Amazon aged inventory surcharge is a monthly charge on FBA units that have sat in the fulfillment network longer than 180 days, billed per cubic foot on top of your regular monthly storage fee. Amazon’s rate card, effective January 16, 2026, runs from $0.50 per cubic foot at 181–210 days to $7.90 per cubic foot or $0.35 per unit, whichever is greater, at 456 days and over (Amazon staff account Angie_Amazon, Seller Forums, data checked 2026-07-31). ...

The Amazon best seller badge — the orange flag on a product detail page — has exactly two publicly stated conditions. Amazon’s seller site puts it in one sentence: “The best seller badge appears on detail pages for products that meet an ordering threshold and rank #1 in a category with at least 100 products” (sell.amazon.com, checked 2026-07-31). So it takes being number one in a category that holds at least 100 products, plus an internal ordering threshold Amazon has never quantified. Amazon publishes no application, no fee and no setting — the badge is an output of sales rank, which is an output of sales volume. ...

Amazon Dropshipping Tools 2026: Which Automation Software Actually Lists and Syncs on Amazon Most software sold as an Amazon dropshipping tool cannot list a product on Amazon or move an Amazon order at all — it is built for Shopify. Of the platforms Amazon sellers ask about most, only four name Amazon as a sales channel on their own pages: AutoDS, which sells separate, more expensive Amazon plans from $64.90/mo month-to-month; Spocket, where Amazon dropshipping unlocks at the Professional tier, $59.99/mo; Doba, which lists Amazon among twelve store integrations from $28.66/mo billed quarterly; and Inventory Source, which lists Amazon first on its integrations page but starts at $199/mo. DSers, Zendrop, Sell The Trend and Minea name no Amazon marketplace integration. All prices and integration lists below were read on each vendor’s own pages on 2026-07-31. ...

Amazon GPSR compliance turns on one sentence of EU law: a covered product “shall not be placed on the market unless there is an economic operator established in the Union who is responsible for the tasks set out in Article 4(3) of Regulation (EU) 2019/1020” (Regulation (EU) 2023/988, Article 16(1), checked 2026-07-31). Article 52 of the same Regulation fixes the date: “It shall apply from 13 December 2024.” ...

Best Amazon Split Testing Tools (2026): A/B Testing Tools Compared With Amazon split testing tools, eligibility decides your options before price does. Amazon’s own Manage Your Experiments splits live detail-page traffic and reports real conversion, but it requires a Professional selling account plus Brand Representative status for a brand enrolled in Brand Registry, and an ASIN with “enough traffic in recent weeks,” per Amazon’s Manage Your Experiments page (data checked 2026-07-31). Fail any part of that gate and no third-party tool restores it: what you buy instead is panel polling, where PickFu, Helpfull, and Intellivy show your variants to recruited respondents and report stated preference from about $1 per response (vendor pricing pages, checked 2026-07-31). ...

Amazon AWD Guide: How It Works, What It Costs, and Who It Fits Amazon AWD (Amazon Warehousing and Distribution) is Amazon’s low-cost bulk storage service that holds your inventory upstream and automatically replenishes it into FBA — and into non-Amazon channels — as demand draws it down. Amazon describes it as a bulk storage solution that distributes inventory to the Amazon store and to non-Amazon sales channels, priced per cubic foot per month with separate per-box processing and per-cubic-foot transportation charges (data checked 2026-07-30, per Amazon’s official Amazon Warehousing and Distribution program page). ...

Amazon FBA reimbursement is the money Amazon owes you when it loses or damages your inventory, mishandles a return, or mis-processes an inbound shipment. Two things decide what you actually get in 2026: the valuation rule — inventory lost or damaged before a customer orders it is reimbursed at your product manufacturing (sourcing) cost, not the retail price — and the filing window, which for most case types is 60 calendar days. Miss the window and the money is gone; leave your sourcing cost unset and Amazon values the unit for you with its own estimate. ...

The Amazon IPI score — the Inventory Performance Index — is a 0-to-1,000 number that grades how efficiently you run FBA inventory. Amazon defines it as “a score that measures your Amazon inventory performance over time,” and says the score, which ranges from 0 to 1,000, is largely based on your ability to keep sold and on-hand (fulfillable or sellable) inventory in balance (sell.amazon.com, checked 2026-07-30). Amazon names four component metrics — excess inventory, sell-through, stranded inventory, and in-stock rate — in a long-standing Seller Forums post (checked 2026-07-30); its public pages define only the first three. The score feeds your monthly FBA capacity limit — the cubic footage you may keep in Amazon’s network. ...

Any Amazon Q4 checklist that starts in September starts too late. Three Q4 2026 deadlines are already running as of July 30, and only one is about inventory: deal submissions for both Q4 event blocks opened July 8, 2026; deals submitted for Prime Big Deal Days by August 5 cost $50 less each; and the first inbound cutoff, AWD for Big Deal Days, falls September 2. The nearest gate is six days out, and it is paperwork, not freight — which is why most sellers miss it. ...

Amazon Seller Flex: How It Works, Who Qualifies, and How It Differs From FBA and FBM Amazon Seller Flex is an invite-only fulfillment program in which you keep your inventory in your own warehouse and run the picking and packing yourself, while Amazon’s logistics network handles delivery and the listings stay Prime-eligible. Amazon’s India seller forum describes it as a program that “allows sellers to fulfill orders directly from their own warehouses while still making those products Prime-eligible for Amazon customers.” Third-party fulfillment guides also report a Fulfilled by Amazon tag on Seller Flex listings; Amazon’s own India forum description stops at Prime eligibility. It is documented on Amazon’s India seller channels, it is not something you can sign up for from a menu, and it is not the same thing as Amazon Flex. ...

Amazon 1P means you sell your products to Amazon at wholesale and Amazon resells them; Amazon 3P means you sell through Amazon directly to the shopper and Amazon takes a commission. 1P is run from Vendor Central, 3P from Seller Central. The practical difference comes down to one question: after the handoff, who sets the retail price, owns the stock, and answers the customer? In 1P the answer is Amazon on all three. In 3P it is you. ...

Amazon DSP is Amazon’s demand-side platform — a programmatic ad buying tool that places display, video, audio, and Streaming TV ads at chosen audiences both on Amazon and across third-party sites and apps. It is a separate product from Sponsored Products and Sponsored Brands, and for most sellers the decisive difference is the entry barrier: Sponsored Ads have no minimum spend, while Amazon’s own pages put a $50,000 minimum on managed-service Amazon DSP and, for Streaming TV specifically, a $10,000 recommended campaign minimum on self-service DSP packages. ...
