Sure.
Our fee ranges anywhere from a fraction of a percent to a couple percentage points. Companies selling $100k diamond jewelry (of which we have several) vs companies selling $100 bikes have different levels of risk.
Most importantly, we typically charge 1/10 the revenue we generate for our clients: https://bolt.com/case-studies. Everyone who's signed up is 10X ROI positive. For a small single digit percent they're making double digit percent more money.
On top of the Bolt Fee, we match processing, and that's about it.
