Everything for Amazon Sellers—in One Base.

The fastest ASIN lookup needs no tool at all: the 10-character code sitting after /dp/ in any Amazon product URL is the ASIN. Everything below is about the cases where that shortcut fails — a page with no ASIN in the URL, a spreadsheet of 400 products, or a supplier list that gives you UPCs instead. All limits and tool statuses here were checked on 2026-08-13. Settle one thing first, because two very different jobs share the phrase “ASIN lookup.” This guide covers the forward direction: you have a product, a link or a barcode, and you want its ASIN. The reverse direction — hand a tool a competitor’s ASIN and get back the keywords that product ranks for — is a different tool category with different free tiers, covered in free reverse ASIN lookup tools. Nothing on this page returns a keyword list. ...

Dropshipping Agents Explained: Not a Sourcing Agent A dropshipping agent buys, packs and ships one unit at a time to your customer’s door, after the sale. A sourcing agent buys a production run before any sale and moves it into your warehouse or into FBA. Same country, same WeChat-shaped working relationship, completely different job — different money, different failure modes. Hire one expecting the other and the mismatch shows up as unshippable orders or unsellable stock. ...

Disclosure: This article contains affiliate links — we may earn a commission at no extra cost to you. This does not affect our rankings or conclusions. Hire an ecommerce accountant when what blocks you is a judgement call, not a data-entry problem. Software splits an Amazon settlement into sales, fees, refunds and tax and posts it to a ledger — that part is solved and cheap. What software cannot do is decide where you owe tax, whether inventory is valued in a way a lender will accept, or which entity should book the revenue. Below are the five gates at which sellers cross from one to the other, how ecommerce accounting firms actually bill, and how to screen one that has closed an Amazon month before. This is orientation, not tax advice — every position here turns on facts a licensed accountant or tax adviser has to see for themselves. ...

Amazon is now automatically translating the text inside your product images into the shopper’s preferred language across 14 stores. It announced this on the official News_Amazon Seller Forums account on 4 August 2026, it applies to sellers of non-media products by default, and there was no opt-in step. Your main image is not translated; secondary images that contain text are. You can override the result — but the only override Amazon documents is replacement, not a switch. Everything below is sourced from the official announcement, data checked 2026-08-13. ...

An Amazon author page is a free profile created through Amazon Author Central, and it groups every book published under one author name in a single place. You create it by registering with your KDP account credentials and claiming one already-published book by ISBN, ASIN, or author name — an author page “does not come standard with use of KDP,” in Amazon’s own wording, so nothing appears until you claim it (KDP Help, data checked 2026-08-13). ...

Walmart Seller Center vs Amazon Seller Central: Fees, Workflow, and What Transfers Walmart Seller Center is cheaper to keep open than Amazon Seller Central and harder to get into. Walmart’s pricing page states that Walmart Marketplace and WFS run with “zero setup, monthly, or hidden fees” (data checked 2026-08-12), while Amazon publishes a Professional plan at “$39.99 / month”. But Walmart’s registration requirements ask for a “Business Tax ID(s) or Business License Number (SSN not accepted)” and a “History of marketplace or eCommerce success” — there is no individual-seller on-ramp equivalent to Amazon’s $0.99-per-item plan. ...

Supply Chain by Amazon: What It Bundles, What Each Piece Costs, and Who It Fits Supply Chain by Amazon is not a product you sign up for. It is an umbrella label Amazon puts over roughly a dozen separately-priced logistics services — freight, bulk storage, replenishment, fulfillment, parcel — that share one inventory pool. And the label itself is changing: Amazon’s program page now states, verbatim, “Supply Chain by Amazon is evolving into Amazon Supply Chain Services (ASCS)” (data checked 2026-08-12, per Amazon’s official Supply Chain by Amazon program page). ...

How to Find Winning Products on Amazon: A Criteria-First Framework (2026) To find winning products on Amazon, write down your pass/fail bars before you open a research tool, then eliminate candidates against those bars in a fixed order. A winning product is not the one with the biggest numbers on a dashboard — it is the one that still clears every bar you set when the numbers are wrong by 40%. The order matters because each gate answers a question the next one assumes — skip ahead and you’re optimizing numbers a later gate can still zero out. ...

Amazon Subscribe & Save for Sellers: Enrollment, Funding Tiers, and When It Pays Off For buyers, Amazon Subscribe & Save is a recurring delivery on a schedule they pick, at a discount. That is the whole buyer story, and it is where most search results stop. This guide is the seller side of the same program. The short version: enrollment is not something you apply for and win. Eligible FBA offers from a Brand Registry brand are enrolled automatically at a 0% seller-funded discount, and your only real lever is whether to raise that to 5% or 10% out of your own margin. Amazon separately funds a 5% discount on subscriptions of five or more items. The program itself carries no extra selling fee. So the decision is not “should I join” — it is “should I fund a discount, and at what percentage.” Data checked 2026-08-12. ...

Amazon Marketing Cloud (AMC) is a clean room: you send it questions, it runs them against your Amazon Ads signals inside Amazon’s own environment, and it returns aggregated, anonymous answers. It is not a dashboard, not a customer list, and not a data export. Amazon describes it as “a secure, privacy-safe, and cloud-based clean room solution in which advertisers can easily perform analytics and build audiences across pseudonymized signals,” and states that it is “available at no cost to eligible advertisers via web-based UI and API” (Amazon Ads, data checked 2026-08-12). ...

Type anything into the Amazon search box and you get 10 suggestions. Not 11, not 50 — ten. There is no setting anywhere in Amazon that raises that number, and those ten are the same ten your competitors see. Amazon Suggestion Expander is a Chrome extension that takes the seed you typed and asks Amazon’s own suggestion service the same question from several angles at once. One seed comes back as 114–117 deduplicated search terms in a first-party probe run on 2026-08-11 — roughly 11.4× what the search box will show you — and every one of them is a phrase Amazon’s own autocomplete considers real. ...

Amazon is removing the seller eligibility step for the Featured Offer, phasing the change in globally through the end of 2026. The short answer to the question sellers are asking: the gate is going away, but performance is not. Amazon moved seller performance from a pass/fail filter that ran before ranking into the ranking itself — it says explicitly that it is “not changing how the Featured Offer is selected.” ...
