Everything for Amazon Sellers—in One Base.

The best-known list of top Amazon marketplace sellers is published by Marketplace Pulse, and it does not rank sellers by sales. It ranks them by how many seller reviews each storefront collected in the last 30 days. The page says so in its own words: “Seller rank is based on the number of reviews each seller received during the last 30 days, which counts feedback received from shoppers after a purchase” (data checked 2026-09-06). ...

To put your Amazon items up for Vine orders you open the Vine tool in Seller Central, enter the ASIN, click Begin enrollment, add the variations you want included, set a unit count between 1 and 30, and confirm. Amazon’s help page for that flow states that “Once the enrollment is submitted, you will not be able to add/remove a product variation from the enrollment or update the quantity of units enrolled” (Enroll a product in Amazon Vine, data checked 2026-09-06). The job is getting the preconditions right before that last click. ...

If you are about to buy an Amazon FBA business, what decides whether the deal is safe is verification, not valuation. Four things must be independently checkable before money moves: that the profit reconciles to Amazon’s own reports, that the inventory is sellable rather than stranded and ageing, that the selling account can lawfully change hands, and that the trademark behind Brand Registry belongs to the party selling it to you. This is the buyer’s checklist for those four gates, built around documents and public pages you can pull yourself. ...

A list of best selling KDP books tells you what already sold. It cannot tell you whether the category behind it is worth your next twelve months — and Amazon will not let you borrow the label anyway: its metadata guidelines forbid “Reference to sales rank (e.g., ‘bestselling’)” in a book’s title or keywords (KDP Help, Metadata Guidelines for Books, checked 2026-09-06). What you can do, free and without a tool subscription, is validate the category yourself, using the Best Sellers lists, the Best Sellers Rank on every detail page, the ratings count on each listing, and KDP’s own written rules for the three category slots and seven keyword slots you fill at title setup. This guide turns those into five pass/fail gates you run in order, stopping at the first failure. ...

There is no normal Amazon FBA startup capital number, and any page that hands you one is quoting an estimate somebody invented. Amazon’s own pricing page publishes fee rates and subscription prices — not a startup total (sell.amazon.com/pricing, data checked 2026-09-06). Startup capital is an output, not an input: the sum of five budget lines you can price for your own product from a first-party source before spending anything. This guide is the method, not the number. Five lines, the derivation for each, the source each number comes from, and a funding gate to run before money moves. It is the working companion to the position this site already takes in the Amazon wholesale business guide: ignore the circulating startup-capital totals and price the components instead. ...

A buyer submits seller feedback from Your Orders, or from the entry point amazon.com/hz/feedback that Amazon labels Leave Seller Feedback: find the order, rate the seller one to five stars, write a comment, submit. Two clocks govern it, both stated on Amazon’s help page: “It can take up to three days after the order is completed or canceled for the Leave seller feedback button to show in Your Orders,” and “You have 90 days from your order date to leave a rating and comments” (data checked 2026-09-05). ...

To ship products from Amazon AWD back to seller-controlled addresses, you file a Multi-Channel Distribution (MCD) order, not an FBA removal order. The path is Seller Central > Supply Chain > Send to Amazon > Move from AWD, then the distribution type Multi-Channel Distribution (Off-Amazon Destinations) (data checked 2026-09-05, per Amazon’s Multi-Channel Distribution using Amazon Warehousing and Distribution (AWD) help page). If the SKU has no active listing, MCD refuses it and the only remaining route is a support case for manual removal. ...

How to Export Amazon Listings to Excel: The All Listings Report Walkthrough To export your Amazon listing catalog to Excel, go to Reports → Inventory Reports in Seller Central, pick the All Listings report (or the Active Listings report if you only want live offers), click Request Report, wait 15 to 45 minutes, then download the file — Amazon delivers it as a tab-delimited .txt, not as a spreadsheet. Two things trip people up: picking a report from the wrong menu, and opening that .txt by double-clicking instead of running Excel’s import wizard, which silently mangles UPCs and ISBNs. This guide covers both, plus every column in the file. Data checked 2026-09-05 against Amazon’s Seller Central help pages. ...

Buyers who search for how to contact an Amazon seller directly get three doors: the seller name on a product detail page, the order row in Your Orders, and the Buyer/Seller Messages tab of Message Center. All three land in the same place — the Buyer-Seller Messaging Service — and once a message is in there, Amazon expects a reply from you within 24 hours of receipt (Seller Central: Communication program policy, data checked 2026-09-05). That is the whole subject of this guide, read from the side that has to answer. ...

The Amazon Merch on Demand size chart is not one size. Amazon organizes its templates by print dimension, and there are eleven of them — from 4500 x 5400 px for a standard t-shirt down to 850 x 75 px for a 12-pack of retractable pens. Every figure below comes from Amazon’s own Merch on Demand resource pages, read on 2026-09-05. One thing to settle before you open Photoshop: per-product exports used to be mandatory and are not any more. The dimensions still define what gets printed, but the upload no longer has to match them exactly — the detail most outdated guides miss, covered further down. ...

Selling Used Items on Amazon FBA: Category Rules and the Condition Trap Yes, you can sell used items on Amazon FBA — Amazon accepts used inventory into fulfillment centers in eligible categories, and charges no extra fee for it. Two things trip sellers up, and neither is obvious from the listing screen. First, some categories are closed to used condition outright, among them toys and games, intimate apparel, medical devices, and anything consumable, ingestible or topical. Second, once a SKU has units sitting in a fulfillment center, its condition is fixed for the life of that SKU — you cannot flip it from New to Used in place. The only route is a removal order and a fresh SKU. This guide covers eligibility, the gated-versus-banned distinction, and the FBA-specific mechanics. For what each grade actually means, see our guide to Amazon’s Used - Like New condition. All policy language below is quoted from Amazon’s own pages, checked 2026-09-04. ...

Amazon Seller Account User Roles and Permissions: Who Can Do What Seller Central has exactly one role with unconditional full access: the primary user, meaning the login that registered the account. Everyone else you add is an “employee” — a secondary user holding per-feature permissions someone granted them. An “administrator” is not a higher tier of access; it is an employee additionally given View and edit on the User Permissions page, which lets them manage other people’s permissions. And “owner” is not a Seller Central sign-in role at all: the account cannot be transferred, so business ownership and account access are two separate facts. Below: each role’s official definition, a permission matrix across inventory, orders, finance, advertising and customer service, and the checklist for the day an employee leaves. ...
