      Where to use Manifeste

      Not just TikTok Shop.

      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.

      DELIVERY4 business days

      Over 4 business days: RISKY. Over 7: NO-GO, the order is cancelled.

      ORIGINFrom your country

      On TikTok Shop in the EU, a parcel shipped from outside your store's country is NO-GO.

      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.
