Recommended workflow

  1. Start with the fee calculator to understand marketplace and fulfillment costs.
  2. Use the sample ROI calculator before sending a new batch of products to creators.
  3. Put sample cost, creator commission, fees, and product cost into the break-even calculator.
  4. Use the ROAS calculator before boosting creator content with paid traffic.
  5. Use the bundle margin calculator when testing bundles, multi-packs, or higher average order value offers.
Planning rule: product cost + fees + fulfillment + creator commission + sample allocation + ad spend should still leave your target contribution margin.
