The Checkout Referrals add-on allows a customer to select an affiliate at checkout (via a select menu or an input field) who will then receive commission on that purchase.

It’s especially useful for sites whose affiliates are NPO (Nonprofit organizations). A customer can select or enter the NPO at checkout, and that NPO will receive a commission on the sale. If an affiliate link is already being tracked (e.g. /?ref=123), the affiliate list or input field is not shown at checkout.
