Reading the Dropship Max CPA output
It combines selling price, supplier product cost, shipping cost and payment and app fees into one decision result using the formula explained on the page.

- Dropship Max CPA assumes that the model includes only the four visible inputs and does not infer hidden platform charges.
If one of these Dropship Max CPA assumptions is false, keep the result as a diagnostic rather than production or decision data, and choose an implementation that explicitly supports the missing rule.
