      Where to use Manifeste

      Wherever you sell.

      A product with no margin doesn't become profitable by switching platforms. The logic is the same everywhere: only the fees change. Pick your situation and Manifeste sets the rates.

      The method

      MARGINx4 or more

      GO from x4, RISKY between x2.5 and x4, NO-GO below, or as soon as nothing is left per sale.

      DELIVERYShip fast

      Over 10 business days: RISKY. On TikTok Shop in the EU, the limit drops to 4 business days, and 7 means NO-GO.

      FEESSet per channel

      Amazon, Etsy, eBay, your store or TikTok Shop: Manifeste applies the fees of wherever you sell. Only the fees change, the rule stays the same.

      Sources and details
      Delivery and origin: these two rules are TikTok Shop's in France, Germany, Spain, Italy and Ireland. Elsewhere and on other channels, Manifeste only lowers the verdict for deliveries over 10 business days. The strictest criterion wins: a good margin doesn't make up for delivery over 4 business days (RISKY), over 7 business days (NO-GO), or a parcel shipped from outside your store's country (NO-GO). TikTok Shop fee in the EU: 9% of the total incl. tax since 8 January 2026, 7% for some categories (TikTok Shop Academy). United Kingdom: 9%. United States: 6 to 8% depending on the category. The other rates are assumptions: replace them with yours. Indicative estimate, no promise of earnings. This isn't accounting advice: have your numbers checked by an accountant before committing money.
