Fees change by channel
Each marketplace has different fee rules. A product that works on one channel may be weak on another after fees.
- Referral fees
- Fulfillment fees
- Payment fees
- Listing or subscription costs
Ads can compound fee pressure
Marketplace ads are often necessary, but they should be evaluated against contribution profit after marketplace fees.
- Compare ad spend to post-fee revenue
- Review TACOS and contribution profit
- Watch low-margin promoted SKUs
Use channel-level profit reporting
Channel-level reporting helps teams decide where to push inventory, where to protect price, and where a product should not be promoted.
- Compare Shopify and marketplaces
- Separate organic and paid marketplace sales
- Review fee changes monthly
