The ability to have all my accounts in one place, from payroll through tax reporting & filings with both state and federal gov't agencies. Also being able to keep track of each employee's health care plans. I dislike how difficult it can be at times to navigate between different areas within the system. If you are looking for an easy-to-use accounting software then this isn't what your searching for! It takes some time getting used to but once familiarized we really like its ease of use. Our team has been very happy since switching over to using bigfish!!
