Everything for Amazon Sellers—in One Base.

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.

Amazon FBA Virtual Assistant: What a VA Costs by Task Type, and How to Vet One The public rate evidence for an Amazon FBA virtual assistant splits into three bands that do not measure the same thing. Hiring-platform tables show asking rates of roughly $3.50 to $5.40 per hour for an “Amazon Store Manager” (OnlineJobs.ph salary guide, last updated 2026-08-26). One published VA agency starts at $7.70 per hour, quoting “$77/wk for a 10-hour weekly contract with an entry level virtual assistant” (20four7VA, checked 2026-09-03). Upwork’s own hiring page tells buyers to budget $15/$35/$50+ per hour by level — while the freelancer cards displayed on that same page listed $3, $6, $7 and $8 per hour. An asking price, an agency’s own rate card, and a budgeting suggestion are three different objects. This guide keeps them apart, prices the work by task type, and gives the red lines that disqualify a candidate before money moves. ...

Amazon FBA Bookkeeping: The DIY Monthly Close From Amazon’s Own Reports You can do Amazon FBA bookkeeping with nothing but a spreadsheet, and the file you need is the Date Range Transaction report (CSV) in Seller Central’s Reports Repository — not the payout statement. Pull one calendar month, split its columns into revenue, contra-revenue, tax liability, and three separate fee buckets, then post one journal entry with the deposit total as the balancing line. That is the method. Below: every column and where it lands, how COGS attaches, and how reimbursements and their reversals get posted without double-counting. All report names, columns, and paths are quoted from Amazon’s public Seller Central help pages, checked 2026-09-03. ...

Amazon FBA Alternatives (2026): One Decision Table for FBM, 3PL, Dropshipping and MCF There are four real Amazon FBA alternatives, not forty: fulfil the orders yourself (FBM), rent someone else’s warehouse (3PL), never hold the stock at all (dropshipping, usually alongside a DTC store), or keep your stock in Amazon’s warehouse but sell it somewhere else (MCF). Which one fits is decided by three things — whether you need the Prime badge, whether your units are odd-shaped or slow-moving, and whether your cash can sit in inventory for weeks before the first sale. This page is the switchboard: one decision table, one paragraph per path, and a link to the full comparison for whichever row is yours. It deliberately does not re-argue any of those comparisons. Amazon-side facts here were checked on 2026-09-03; figures carried over from our deeper guides keep their own check dates. ...

The Amazon PPC Audit: A 90-Minute Pass That Finds Wasted Spend An Amazon PPC audit is a fixed pass over an account that is already running: pull four downloadable reports — targeting, search term, placement and budget — sort each one by cost, and judge every expensive row against a threshold you set before you open the file. Ninety minutes is enough because an audit is a diagnosis, not a rebuild. What you produce is a short list of bids to cut, targets to pause, negatives to add and budgets to raise, plus a dated log of every change. ...

Amazon Seller Policy Updates: The Official Channels and a 20-Minute Monthly Routine Amazon publishes seller and FBA policy changes in a handful of specific places, not one feed. The authoritative record of policy-text changes is the Changes to program policies help page; the fastest notice of an upcoming change is the News and Announcements category of Seller Forums; money changes land on the fee schedule; and anything aimed at your account specifically only appears behind a Seller Central login. Everything below was opened and read on the date given, data checked 2026-09-02. ...
