Shipping, packaging, transaction fees, storage and returns all come out after the sale. Very few brands have added them up against a single order.
Once contribution margin is on the table you can say what a customer is allowed to cost, and what the account does at three times the volume.


It runs entirely in your browser, and nothing about your account is uploaded.
