FAQ
Common questions
What is break-even ROAS?
It is the ROAS level where the order stops losing money after all included costs.
What is max CPA?
Max CPA is the most you can afford to pay for one order before the order becomes unprofitable.
Why not use revenue alone?
Because ROAS can look healthy while profit is weak if fees and fulfillment are heavy.
Should I use platform-specific fee assumptions?
Yes. Use the fee stack that matches the channel you are buying traffic for.
What should I do after this?
Use Product Pricing to rework the offer or compare against Shopify Profit or Resell Profit for channel choices.
