The most expensive scam on this list doesn't involve a fake supplier at all. It starts after you've found a real one. Seven schemes, the warning sign for each, and why slowing down beats every one of them.
New York requires a Certificate of Authority before you can issue Form ST-120, and you must register 20 days before your first taxable sale. The full process, the blanket certificate rule, and the out-of-state exception.
Fewer new sellers joined Amazon in 2025 than any year on record, while million-dollar sellers nearly doubled. Amazon didn't get worse. It got professional. Here's the roadmap for entering it with a plan.
Suppliers use these labels loosely, and the label decides two things: what you pay, and whether your paperwork holds up when someone asks where your products came from. The three types, sorted out properly.
Amazon never doubted your product. It wants to know where it came from, and it only accepts the answer in one format. What to do in the first 48 hours, and the paperwork that ends the complaint.
Ads say $500. Forums say $25,000. The real answer is about $5,000, and the reason isn't the first order. It's the cost almost every new seller forgets to budget.
Sometimes a real invoice from an authorized distributor still gets rejected. That's because the brand has a say in who sells its products. Here's the four-step path that works.
The product is 100% genuine, the invoice is real, and the account still goes down. How gray market enforcement actually unfolds in 2026, step by step, and the four signals that expose gray supply before you wire a dollar.
Your ungating application came back asking for a "letter of authorization from the brand." What the LOA actually is, the five terms Amazon checks, and the distributor-letter mistake behind most rejections.
Florida issues your resale certificate automatically when you register, but Form DR-13 expires every December 31. How to get it, print it, renew it, and use it correctly with suppliers.
Scan Unlimited's Chrome extension leads to a dead store page and the paid plan is now $70. Five alternatives compared on the price of the plan you'd actually use, not the headline tier.
California doesn't require a specific resale certificate form, but it does require an active seller's permit. How to get one from CDTFA, complete CDTFA-230, and why out-of-state certificates don't work here.
