Make sure you have a standard disclosure on each page of your website that includes affiliate links, and that you have a full disclosure page somewhere where your potential clients can learn more. You don’t want to go through all the work of developing your packages only to find out they’re not compliant.

Given the opportunity cost of equity, a company can have positive net income but negative residual income.
