This study focuses on the problem of small service business debt collection from delinquent customer accounts and the ways in which quality control methods can be applied to analyzing the occurrence of past due payments. Small businesses like Helthkare Products, LLC are particularly vulnerable to the risk of lower finances because of a limited source of revenue. Their customer bases tend to be smaller and therefore cannot afford to have too much outstanding debt from its customers because it puts them in a position of having a reduced working capital. The use of quality control can help small businesses understand their customers as well as their own internal business processes to make them more efficient so as to avoid and reduce delinquent payments.
