After the implementation of treasury centralized payment, under the direct financial payment mode, the financial funds used by the grass-roots budgetary units are no longer allocated by the competent departments, and the wage payments are directly appropriated from the financial sector to the personal wage accounts. The purchase of goods or services is directly appropriated to the suppliers by the finance. Under the fiscal authorization payment method, although the payment instruction is issued by the budget unit, the finance does not allocate the monetary fund to the budget unit, but pfers the amount of money to the zero account or petty cash account of the budget unit.
