As noted by the Small Business Administration, more than half of Americans own or are employed by a small business. As a small business owner, you play a critical role in creating new jobs, driving innovation and improving the outlook of American companies on the global market; and, as you know, accomplishing these aims demands significant time and effort, especially when it comes to meeting compliance requirements for small business.
