1, the gross margin of direct sales is greater than the gross margin of distribution, because direct sales can reduce the middleman to earn the difference in price, which reduces the cost of increasing profits.
2. The expense ratio of direct selling is smaller than that of distribution because direct selling does not need to pay the middleman's fees, thus reducing the selling expenses.
3. The net interest rate of direct selling is greater than the net interest rate of distribution because direct selling reduces costs and improves profits and also reduces selling expenses.
