Traditional managed CPA bundles agency fees with media spend, making the true per-conversion cost hard to see. A cleaner structure passes media through at cost and charges a transparent per-verified-conversion fee, so you can separate what you pay the platform from what you pay the channels.
At Forward, campaigns are billed per verified conversion ($50 fee, media at cost), with the conversion verified against your definition via your own tracking before billing. Related: how AI agents pay.
