Seller math guides

Plan creator deals with margin first

Creator commerce can compound when the unit economics are clear. A product that survives commission, fees, fulfillment, returns, samples, and paid traffic can be scaled with more confidence than a product that only looks good at gross margin level.

Practical workflow

  1. Set a target contribution margin before recruiting creators.
  2. Use conservative sample conversion assumptions.
  3. Separate creator commission from ad spend so you can see which lever is hurting profit.
  4. Review official Seller Center statements after real orders come in.
  5. Update your calculator defaults when platform rules or category fees change.
