A brand walks MAGIC or Cosmoprof, signs a dozen accounts, and four months later finds its own product on Amazon at a price it never authorised, sold by a company it has never spoken to. That is the most common marketplace conversation we have in this city, and it is not really a marketplace problem — it is a distribution control problem that surfaces on a marketplace. The fix is boring and it works: brand registration, a written MAP position, a documented authorised-seller list, and a first-party listing good enough that nobody has a reason to buy the grey one.
Underneath that sits the strategic question. A marketplace is rented shelf space with its own search engine, its own ad auction and its own fulfilment network, and the shopper it delivers belongs to the platform, not to you. We do not tell Las Vegas brands to stay off Amazon — most are already there. We run it for what it is genuinely good at, which is discovery from people with no prior relationship to you, and then build the reorder path onto your Shopify store through pack sizes and bundles the marketplace does not carry, insert cards that offer product registration and warranty, and the Brand Registry tools Amazon actually permits for reaching your followers.
The channel mix here splits by what you sell. Combat sports and fitness gear, Arts District beauty and anything that demonstrates in fifteen seconds of video has a real case on TikTok Shop, where catalogue sync and creator sample seeding are marketplace mechanics rather than a separate affiliate programme. Hospitality and foodservice suppliers belong on Amazon Business, where a hotel or restaurant purchasing manager can clear a reorder without opening a new vendor file. Memorabilia, one-of-one collectibles and discontinued production gear are one of the few categories where eBay is still the right answer and we will say so. Walmart Marketplace is worth a second channel once Amazon is stable and the catalogue can be maintained twice.
