What are the onboarding steps?

Four: connect Shopify, watch the import, connect your ad accounts, and a summary of exactly what came in. It is deliberately short, because the four cost engines are real work and belong in the app where you can take your time rather than in a wizard you are trying to get through.

The last screen is a receipt rather than a congratulation: how many orders were pulled and over what window, and one row per connected ad platform with its real spend total. A platform you did not connect shows no row at all, because a zero would read as a synced platform you spent nothing on.
