Your question is very vague....

What are you looking for in "MLM" a way to track sales of each of the people?

ODOO is a ERP system, what it tracks is up to you, and how you configure it. Another you might look at is one I support ERPNext.

In the end you should come back with more info in your question, be more specific about what you want, and tell us what you think an MLM module should do for you.
