Nothing. We have accountants that we like and have had them as advisors for 20+ years. They guide our internal bookkeeper and management . They are big on self help and a quarterly or semi annual meeting. They understand the nature of a law practice and the reporting requirements. They are flexible in never selling us more than we need from them and by forcing planning for the future whether growth or shrinking. They also refer clients to our firm. Its been a good relationship for many years.
