Payment fees come off the top
Payment processors take a percentage plus a fixed fee on each order.
Your price needs to cover these fees, not just product cost.

Monthly Shopify plan fees should be spread across your expected monthly orders.
This creates a true per-order profit view.
Include marketing CAC
If you spend on ads, allocate CAC per order.
Ignoring CAC can make healthy revenue look profitable when it is not.
