Account, Entity, and the Rules You Cannot Break

This is the paperwork lesson, and it is also the one whose shortcuts suspend people. Do it during the freight-window dead time from "Suppliers, Samples, and the Freight Decision," not in a panic the week your inventory lands.

The seller account

Register through Amazon Seller Central. Expect identity verification including a video call for new accounts; failed verification is a real suspension trigger sellers report on the Seller Forums, so have your documents clean and your answers boring. Choose the Professional plan at $39.99 a month: you need it for advertising, Buy Box eligibility, and bulk tools, and the individual plan's per-item fees punish exactly the seller you are trying not to be.

The business shell

An LLC is the standard choice for sellers, for the liability separation and the clean tax line, with costs varying by state. Four accounts, opened in one sitting: the LLC, the EIN from the IRS, a business checking account, and a business card. Every dollar of this business flows through those, never your personal accounts. When you reconcile the cash-conversion loop later, you will thank yourself; mixed finances turn a healthy business into an unexplainable one. And if a layoff is what pushed you here and this is your first entity, the on-ramp frames the whole transition this paperwork sits inside.

Sales tax has a twist worth knowing: most US states now hold Amazon, the marketplace facilitator, responsible for collecting and remitting sales tax on your behalf. Economic nexus laws can still reach you as your sales grow, so note the topic for an accountant conversation in your first quarter, and do not let it block your launch.

Codes, brands, and Brand Registry

Every product needs a real barcode. Amazon validates them against the GS1 database, and UPCs that do not match GS1 records are treated as invalid, which is where cheap resold barcodes die, a recurring Seller Forums complaint. Buy prefixes or single GTINs from GS1 directly; it is a few hundred dollars and it is the difference between a listing that exists and an error message.

The brand path: register your brand name as a trademark with the USPTO, roughly $350 per class for a standard application, then enroll, for free, in Amazon Brand Registry. Enrollment unlocks A+ content, brand analytics, stronger hijacker protection, and the Vine review program you will use at launch. On a lean budget, file the trademark when the product proves itself, but run a USPTO search before you even sample: discovering your name is taken after printing labels is an avoidable wound.

The rules that end accounts

Amazon's enforcement is account-level and often sudden. The lines that matter most:

Never manipulate reviews. No incentivized reviews, no review swaps, no friends and family leaving reviews, no "free product for honest review" insert cards. Amazon sues review-brokering services and suspends the sellers who use them; the crackdowns are years running at this point. The legal lanes are Amazon's Vine program, which charges up to two hundred dollars per parent product and requires Brand Registry, and the plain request-a-review button on each order.

Never open a second account. Linked-account suspensions are common and slow to appeal.

Sell what you are allowed to sell. Gated categories, restricted products, and safety-regulated goods each carry their own approval walls. Ignorance here strands inventory.

Keep performance metrics clean. Valid tracking, fast handling, low defect rates. These are the dials on your account health page; check them weekly forever.

With the account ready and freight on the water, your job turns to the storefront itself, the page where all your research either sells or does not.
