I love the OWL at Purdue, and it's a great resource.
If the triple S of business's bothers you, you can rewrite: the X of the busines. Or you can say something like "the organization's X" instead.
Please note (both of you) that proper English sentences require proper capitalization and punctuation. There's not much point in getting worried about ss' or ss's if you're not going to pay attention to those points as well.
