优化OE货款回款，提升企业资金效率

Revise: The current OE funds have not yet experienced overdue payments, but the long repayment period and high acceptance repayment ratio have resulted in a large amount of accounts receivable, leading to low efficiency in the company's capital utilization. The market department can try to communicate with customers to shorten the repayment period, and the finance department should strive for the maximum cash repayment ratio, reduce accounts receivable turnover days, and work hard to achieve the operating capital turnover target.
