It seems like you're thinking about this in terms of perceived value fairness instead of objective if/then outcomes. If your friend hadn't brought the client to you, you would get exactly $0 from them. Ever. 80% of a profitable amount is a hell of a lot more than 80% of nothing. If you've never actually landed a client yourself, it's a lot more difficult than you're likely thinking it is. I highly doubt this is merely an introduction based on nothing - more likely your friend has been working his network for a long time, vetting potential people who need work done, ruling out the ones that can't or won't pay a decent rate, setting up a business and all the contracts you need beforehand to make it easy to get started, etc. You're also probably not accounting for the fact that being a subcontractor has a lot of benefits. You're not that one that needs to chase POs, AP payments, renewals, etc. on a regular basis. To your last question, it tends to be a spectrum in practice. A casual introduction that leads to a deal with no actual involvement from the salesperson will have a lower rate (possibly one-time) than one where the person is setting up the whole deal and subbing it to you. In your case, your friend already quoted the company a rate and they're ok with it, so this isn't a casual intro - he basically did the hard part for you.
