Property manager's right to keep late fees questioned

Question: I own a 20-unit rental property and have a property management company. One of my renters is having difficulty paying rent on time and I have just noticed that the property manager is keeping the late fees as opposed to passing the fees on to me. Her response is that this is standard practice, but I am sure that my previous manager forwarded the fees to me. What is the proper procedure in these cases?
