“if someone comes in and they charge $10,000 for one call call and then we get a charge back and it might be like messy with Marketplace and so on and money needs to go different places and so on we might end up with like a pretty big Bill ourselves um but I think people can come in they have a certain limit let's say you know $300 per month”

Cap individual transaction size on your marketplace to bound chargeback risk

On a marketplace you carry the chargeback risk when transactions go bad — even though the supplier kept the money long ago. Set explicit per-mentor / per-listing price caps that match your reserve cushion. MentorCruise started supply-side caps around $300/month and progressively lifted them as the business matured. Don't accept $10K-per-call listings until you can absorb the chargeback without losing a month of profit.
