Creator flat fee versus CPA: a reader-input sheet

Compare flat creator fees to CPA payouts with illustrative inputs; disclosure duties cited from FTC endorsement FAQ.
Flat fee, CPA, and hybrid deals need the same payer definition before you compare them. FTC staff guidance still applies to disclosure when codes or paid posts are involved (Endorsement Guides FAQ). Downstream efficiency can be expressed with AppsFlyer-style ROAS once revenue and cost are joined (Activity metrics).
