If it is purchased by a vegetable farmer, the village where the vegetable farmer is located shall issue a certificate (proving that he grows vegetables) and carry a copy of the vegetable vendor's ID card. Issue a unified invoice to the national tax department. Agricultural products are tax-free and only the invoice cost is charged. If it is not the first invoice, no production fee will be charged.

This problem generally exists in all enterprises, especially catering enterprises. Vegetable procurement is very prominent, and some local taxes are not explored. Some local tax authorities do not recognize the cost of IOUs and pay fines, which causes great losses to enterprises.

For enterprise accounting, it can only be recorded according to the documents provided by the salesman.
