It depends on the types of services you offer and who uses those services. As a start-up it's easy to think this is N/A for you but if any of your clients are publicly traded or use your products/services as part of their work for their clients who are publicly traded you may find that this impacts you as they will be asking for things like audit-trail capabilities, etc.
Senior management of publicly-reporting companies has to certify that the financial statements are correct now, due to Sarbanes-Oxley. This requires massive audit expenses (to be sure that the financial reports are right), and there is significant liability for those executives if the financial reports are wrong. So a public company can either spend a ton of money on audits or not be public. It's a lose-lose situation.
