Fees and margin are not interchangeable
A marketplace fee percentage is applied to the sale base defined in this form, while product, fulfillment and advertising costs are separate expenses. Profit margin divides profit by revenue rather than by product cost. A positive per-order profit does not include fixed business costs unless they have been explicitly allocated into the inputs.
