Everything for Amazon Sellers—in One Base.

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. ...

Amazon FBA ROI Calculator vs Fee Calculator: The Two Numbers Are Not the Same A fee calculator answers “what is left of this sale after Amazon takes its cut.” An ROI calculator answers a different question: “what does each dollar of my own money earn, and how long until I get it back.” ROI = net profit per unit ÷ total invested capital per unit — where invested capital is goods cost plus first-leg freight and duty plus prep and labeling, not the sale price and not the margin percentage. That denominator is the whole difference. Two products can print an identical 19.5% net margin and return 52% and 87% on capital, and only ROI tells you which to reorder when cash is the constraint. Below: the exact denominator, a two-SKU worked example you can recompute line by line, how to derive your own ROI floor, and how payback period sets reorder cadence. ...

Amazon FBA Germany, Japan and the Netherlands: The Gates Each One Makes You Clear First Germany and the Netherlands are two doors into the same building. Japan is a different building. One EU EORI number covers both European countries — “at any point in time, a person can be assigned only one valid EORI number” — but each still wants its own tax registration and its own packaging register, and the PPWR that has applied EU-wide since 12 August 2026 harmonised who counts as a producer without merging those registers. Japan asks for no EORI and no packaging register at all, and instead imposes the hardest blocker here: a person living abroad cannot lodge a Japanese import declaration without first appointing a Customs Procedure Agent resident in Japan. Germany owns the second blocker, and it is not tax — a producer with no German subsidiary cannot register batteries or electricals itself at all. Every rule below is quoted from a government, EU or Amazon page, checked 2026-09-04. ...

Amazon Business Reports: Find Your Conversion Bottleneck for Free Seller Central’s free Business Reports already tell you which step of your funnel is broken — you just have to read three columns in order. Sessions says whether shoppers reached the page. Buy Box Percentage says whether your offer was buyable when they got there. Unit Session Percentage says whether the page persuaded them. Whichever of the three moved is the step that broke; the other two are downstream noise. This guide walks the Sales Dashboard and the Detail Page Sales and Traffic report field by field, then ends with a table of the signals that mean the free reports are enough — and the signals that mean it is time to pay. ...

Shipping from China to Amazon FBA: The Four Decisions, in Order Shipping from China to Amazon FBA is not one process, it is four decisions that lock in a fixed order: which mode moves the goods, who is named importer of record, who is legally qualified to move and clear it, and what date each of those choices forces on your calendar. Most sellers make decision one on price alone, discover decisions two and three at the port, and find out about decision four when a restock window has already closed. This guide is the connecting layer only. It tells you which decision comes first, what each one forecloses, and where to go for the detail — every branch links to the page that works it through properly. ...

How to Print FBA Labels: FNSKU Item Labels and Box Labels, Step by Step Every FBA shipment needs two completely different labels, printed at two different points in the workflow. The FNSKU item label goes on each individual unit and must be printed between 1 x 2 inches and 2 x 3 inches, in black on white non-reflective stock, at 300 DPI or higher. The FBA box ID label goes on the outside of each carton and prints at 3 1/3 x 4 inches, or 4 x 6 inches if you select thermal printing paper. Item labels come from Manage Inventory or the Send to Amazon workflow; box labels are generated by the shipment workflow itself and are unique per box. Every specification below is quoted from a publicly readable Seller Central help page, linked at the point of use, checked 2026-09-03. ...
