u can use word -должен- like owes something *for ex mp. you owe me money -ты должен мне денег . something like that or *have to or must *
Надо means necessity, need. It stands for things you need to do whatsoever. For instance, we all need food (otherwise we die). The closest word in English here is 'need' (as a verb).
Должен puports an obligation. Moral or external (so, должен is hereby a synonim to both 'must' and 'have to').
