Double-entry accounting vouchers can clearly display the loan direction and amount corresponding to each business, which is conducive to accurate accounting and understanding of the flow of funds.

In double-entry accounting vouchers, each economic business will have corresponding debit and credit records. The total debit and credit amounts must be equal, which is in line with the debit and credit balance principle in accounting.

The disadvantage of single-entry accounting vouchers is that they cannot visually display the credit-debit relationship and are not suitable for complex economic businesses.
