Final answer:
Kleen-Up Company increased the late payment charge to improve their cash flow and incentivize clients to pay on time due to a decrease in their receivables turnover ratio.
Step-by-step explanation:
Kleen-Up Company decided to increase the late payment charge imposed on clients because their receivables turnover ratio has decreased. The receivables turnover ratio is a financial metric that measures how quickly a company collects payments from its customers. A lower ratio indicates that it takes longer for the company to collect payments, suggesting potential issues with late payments or customers delaying payment. By increasing the late payment charge, Kleen-Up Company aims to incentivize clients to pay on time and improve their cash flow.
