Note: The returned products carry value in themselves, which play an important role in return rate profitability calculations, but are intentionally left out in this template.

Row 10 – Fulfillment Cost: Include transactional fees to strengthen your calculation.

Row 26 – CRM Cost: The template can be used to give you an idea of a single transaction. If you want to use it for recurring transactions row 26 is for the CRM costs (reactivation etc).
