What should be written down before a referral is made?

At minimum, the parties should agree who the client is, who made the introduction, whether the benefit is a referral payment or client discount, whether the referrer remains involved, and whether the model is referral, reseller or white-label.

This does not need to be overcomplicated for a small introduction, but it should be clear enough that everyone knows what happens if the client proceeds. Commercial terms should always be agreed clearly before a client is approached, so the relationship stays clean and the expectations stay realistic. That keeps the message practical and makes it easier for a prospect to see where SupplyOnly.com fits.
