You need to consider this in your contract with the provider. If you are going to be responsible for interacting with the collection agency your time should be covered. This is another problem with % billing, it doesn't usually cover your time spent on assisting with collections. Your contract should spell out whether or not you will handle getting the needed information to the collection agency. For some of our clients we refer them to a collection agency and they are responsible for getting the information to them, for others we handle it.
