Answer

You can end a sentence with "~합니다" unless you make a question. "~합니까" is 
asking. And now I can see where you felt strange about "~이에요"

Unlike "합니다/합니까?", you can use "~이에요" for a statement and a question. 
Only difference between is your tone. When it's a statement, your tone at the end
goes flat. If it's a question that ends with "~이에요?", you should go up with your
tone at the end.
