ABBIE.ca makes a good point. What you do with your certification is very important and will impact your business and your reputation.
From a pure business perspective, having the certifications may also allow you to participate in different programs. For example, to participate in the Microsoft Certified Partner program, one requirement is to have staff that are Microsoft Certified Professionals. This is worthwhile for stuff like free licenses, marketing opportunities, referrals, beta/alpha software...etc.
