Drs. Findley and Rocker are partners in a family medicine practice. The practice appears to be busy and well run, but always seems to be short on cash at the end of the month. Billing rates are appropriate, and staff member salaries and draws of the partners are in line with the area. You are the practice administrator, and the partners have asked that you review the problem and make recommendations. What areas will you look at to improve the revenues of the practice?
