Everything for Amazon Sellers—in One Base.

A KDP royalty calculator is only as good as the pricing rules behind it, and on 7 July 2026 Amazon changed one of them: the 70% royalty band for Kindle eBooks on Amazon.com now runs $2.99 to $12.99, up from $2.99 to $9.99 (KDP Help, “eBook List Price Requirements”, data checked 2026-08-14). Of the six free calculators whose eBook rules could be read on 2026-08-14, five still show the old $9.99 ceiling — price a book at $12.99 in one of those and it tells you that you earn 35%, when Amazon now pays 70%. ...

An EORI number is a customs identification number, not a tax registration. You need one whenever your goods cross a customs border and a declaration is lodged in your name — which for Amazon sellers means importing stock into a UK or EU fulfilment centre. The rule that trips people up is that the UK and the EU now run two separate registers: HMRC issues GB numbers, and each EU member state’s customs authority issues EU numbers. If you import into both, you need one from each side. Both systems apply the same test: you register where your business is established, or — if it is not established there — with the customs authority for the place where you first carry out a customs activity. ...

The Amazon Service Provider Network (SPN) is Amazon’s own directory of third-party service providers — photographers, cataloging teams, ad agencies, VAT firms, prep centers — that sellers can browse and contact from inside Seller Central. Amazon says it vets the providers listed there. It also says, in the same FAQ, that it “does not endorse any service provider or its services” (data checked 2026-08-14). Both statements are true at once, and the gap between them is the whole point of this guide. Amazon publishes what a provider must submit to get listed. It does not publish a scoring rubric, a performance threshold, or a re-review schedule. So SPN is a useful filtered starting point and a poor substitute for your own due diligence. Here is exactly what is verified, what is not, and how to read a listing accordingly. ...

Yes — Amazon Rufus is now Alexa for Shopping. Amazon confirmed the rename in its own newsroom: an editor’s note now sits at the top of the original February 2024 Rufus announcement and reads, verbatim, “On May 13, 2026, Rufus was renamed Alexa for Shopping.” The Rufus name is retired as a customer-facing brand. The assistant itself was not shut down and replaced — Amazon describes Alexa for Shopping as Rufus’s product expertise merged with the personalization of Alexa+, and its own how-to page still dates the assistant’s launch to February 2024, which is Rufus’s launch date. ...

Short answer: as of 2026-08-14, the only statement Amazon has published in a page we could actually read is that Haul “is currently operating on an invite-only basis” and that interested sellers “may reach out to [email protected]” — posted by Amazon moderator accounts in Amazon’s own Seller Forums. There is no Haul sign-up page on sell.amazon.com (both /haul and /programs/haul return 404, checked 2026-08-14). Amazon does publish seller-facing Haul help articles inside Seller Central — a program policy, a countries list, listing and inventory instructions — but their bodies load only behind a signed-in seller session and could not be read for this guide. ...

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). ...
