This is where a photographer loses money, not on the day rate. You shoot for a folder and two years later your picture is on a billboard in three countries. Without paper that is your word against the client, and that is the one you lose. So write it down before the shoot, not after.
The tool does not invent a price for the usage rights and no premium per medium or per country. Those rates differ per market, per kind of work and per client, and no single number is right for everyone. You set your own amount; the tool makes sure it is written down.
