i agreed to work for a small company for a salary and 20% of the increase in profit that I added to the business. How do we account for this so that I don't have to earn the bonus twice. My concern is that the bonus at the end of the first year will be added into the costs of the second year . For example.Before I came business was making 100 pa net profit. At end of second year I have increase this to 200 pa net profit. My bonus is 20 (200-100 x 20%). If the business made 200 the third year, would the bonus for the second year have to be paid out of the third years profits, thus reducing my bonus?
