Everything for Amazon Sellers—in One Base.

The Amazon FBA Revenue Calculator (the public version lives at sellercentral.amazon.com/revcalpublic) prices four cost lines and only four: Amazon’s own page describing the tool states it “takes into account common fees like referral fees, fulfillment costs, monthly storage costs, and variable closing fees” (data checked 2026-08-10). Everything else that decides whether a product actually makes money — long-term storage, removal orders, return processing, inbound placement, advertising, freight and duty into the warehouse — either has to be typed into the miscellaneous cost field by hand or does not appear at all. So the calculator is a fee estimator, not a profitability verdict. Read it as the first line of a margin model, then run the gate checklist below before you commit cash to inventory. ...

An inventory tracking system for Amazon FBA is three things, not one: a ledger that holds every unit in exactly one state, two computed thresholds — a reorder point and a safety stock level derived from your own sales and lead-time history — and a set of sync gates that refuse to let a stale or unreconciled number trigger a purchase order. Most sellers build only the first part, read the dashboard, and call it a system. The dashboard is an input. The system is what decides when that input is trustworthy enough to spend money on. ...

To cancel an Amazon seller software subscription without losing money, act before the renewal date, not after the charge — every vendor terms page we checked on 2026-08-10 ties the deadline to the renewal date, and most refund windows run from the purchase or charge date rather than from the day you notice. That single fact explains the majority of billing complaints in our review corpus. The four traps below — auto-renewal, trial-to-paid conversion, upfront annual billing, and short refund windows — are all published in the vendors’ own terms. They cost money because sellers do not read them until the charge lands. ...

Dimensional weight (DIM weight) is length × width × height in inches divided by a carrier’s divisor, and you are billed on whichever is greater: dimensional weight or actual weight. As of 2026-08-10, the divisor is 139 for UPS package shipments, 139 for all FedEx services, and 139 for USPS rectangular parcels over one cubic foot. That single number sets a hard line: any box lighter than 12.43 lb per cubic foot is billed on the air inside it, not on the product. This guide gives the exact rules per carrier with sources, the density math that tells you which side of the line a SKU sits on, and where the same arithmetic reappears inside Amazon’s own fee schedule. ...

For an established Amazon seller, DTC ecommerce is not cheaper than Amazon — it is a different bill. Amazon charges a referral fee that includes demand; a direct-to-consumer store removes that fee and hands you the cost of creating demand yourself. On a $29.99 single-unit product with typical fees, moving one order off Amazon frees up roughly $3.33 of margin, which is your entire budget for acquiring that customer. DTC wins when repeat purchases, order value, or an audience you already own push that number well past $3.33. It loses when every order has to be bought with a fresh ad click. ...

Amazon Automation: Legit Software vs. the “Done-For-You” Store Model “Amazon automation” is one phrase covering two unrelated things. The first is ordinary seller software — repricers, restock forecasting, bid management, reimbursement auditing — that you buy on a monthly subscription and operate yourself inside your own account. The second is a business opportunity: a company charges you a large upfront fee to open and run an Amazon storefront on your behalf and promises “passive income” from it. The U.S. Federal Trade Commission has brought civil enforcement actions against multiple operators of the second kind, several of which have ended in permanent industry bans. The two categories look similar in an ad and behave nothing alike in a contract. This guide separates them, lists the FTC record with primary sources, and gives you a checklist you can run before any money moves. ...

Amazon Handmade: Eligibility, Fees, and the Artisan Application (2026) Amazon Handmade is an application-gated storefront inside Amazon for makers who craft their own products. To sell there you need an approved Professional selling account, products that fit one of Amazon’s five handmade classifications, and an approved artisan application. The headline economics: Amazon charges a 15% referral fee or $0.30, whichever is greater, and the $39.99 monthly Professional plan fee is waived after a one-time first-month payment for approved Handmade sellers. All figures on this page were checked against Amazon’s official pages on 2026-08-09. ...

Amazon Price Match Policy and Fair Pricing Policy: Buyer Rules vs. Seller Rules Two different questions hide behind the phrase “Amazon price match policy,” and they have opposite answers. If you are a shopper: Amazon does not price match. Its Price Matching help page states, “We strive to maintain low and competitive prices on everything we carry. We constantly evaluate Amazon’s prices to offer customers low, competitive prices every day. As a result, we don’t offer price matching” (data checked 2026-08-09). If you are a seller: the rule that governs your prices is the Amazon Marketplace Fair Pricing Policy, and breaching it can cost you the Featured Offer, your shipping privileges, or your selling account. ...

You can watch Amazon trends without paying for a research tool, but only from four public sources, and each one answers a different question. Amazon Best Sellers tells you what is selling now in a category. Movers & Shakers tells you what changed in the last 24 hours. Brand Analytics tells you what shoppers typed — if you are in Brand Registry. Google Trends tells you whether interest exists off Amazon. None of them publishes unit sales, and each lags reality in its own way. This guide covers what each source actually states about itself (checked 2026-08-09), where it misleads, and how to cross-read all four in about half an hour a week. ...

MOQ stands for minimum order quantity: the smallest number of units a supplier will produce or sell in a single order. Alibaba.com’s own seller blog defines it as “the lowest number of units a wholesale supplier allows buyers to purchase at one time” (checked 2026-08-09). For an Amazon seller, the MOQ is not a manufacturing detail — it is the number that decides how much cash you lock into one unproven ASIN, for how many months. A reasonable MOQ is one you can sell through inside a cover window you chose in advance, at a sales rate you can defend with data. This guide covers how to calculate that ceiling first, and only then how to move the supplier’s number toward it. ...

Amazon Ads certification is a set of free, self-paced credentials earned inside Amazon Ads Academy. You pick a track, work through its short courses, then pass one online assessment with a two-hour time limit. Amazon Ads Academy states plainly: “It is free to create an account” (data checked 2026-08-08). There is no proctoring fee, no exam center, and no application. The credentials do expire — each PDF certificate carries an expiration date, and recertifying means redoing the modules and the assessment. This guide covers the tracks that are actually live today, what the assessment format really looks like, a prep plan that fits around client work, and an honest read on who gains from the badge. ...

Short answer: Amazon Buy for Me is an AI feature inside the Amazon Shopping app that places an order for a shopper on a merchant’s own website, without the shopper leaving Amazon. It sits on top of a wider program called Shop Direct. As of 2026-08-08, Amazon’s merchant FAQ states the program is available to U.S. customers, that merchants pay nothing and Amazon takes no referral fee on Buy for Me purchases, that the merchant remains the seller of record, and that a merchant can be removed by emailing [email protected]. If you sell only on Amazon, this changes nothing about your listings today. If you also run a direct-to-consumer site, your public product data and your checkout are now a machine-readable surface Amazon may already be reading. ...
