1. Credit period decision Credit period decision is to analyze the impact of changing the current credit period on revenue and cost. So as to seek a more favorable credit period scheme. Now, take Company A as an example. Suppose that Company A intends to change the credit term for customer X. According to X's credit evaluation, its credit score is 50 points, and Company A has three credit terms to choose from. See Table -3 for the specific decision-making process. As can be seen from Table -3, choosing scheme 1 will increase the monthly profit of enterprise A by 1907 yuan, choosing scheme 2 will reduce the profit by 284 yuan, and choosing scheme 3 will reduce the profit by 6643 yuan. Therefore, the scheme 1 is the ideal choice for company A at present, that is, shortening the credit period to 30 days.

Cash discount policy Cash discount policy should be related to the decision-making during the credit period. Because the discount period can only be shorter than the credit period, that is, customers can only enjoy the discount if they pay in advance within the established credit period, otherwise providing commercial credit to customers will bear additional risks and the decision-making within the credit period will lose its meaning. Formulating cash preferential policies is to ask customers to pay in advance at a specific time and at most how much discount they can give. Still taking Company A as an example, assuming that the cash discount policy finally formulated by Company A is (a/ 10, b/20, N/30) (a and B are natural numbers), then according to the fact that the financing cost is less than or equal to the return on investment, there is the following relationship: (A/100)/(kloc-0/.
