Invoice is an important voucher in a transaction, which contains the basic information of the transaction, such as goods or services, transaction amount, buyers and sellers. If the invoice provided in the performance certificate cannot prove the authenticity and legality of the transaction, the value of the performance certificate will also be affected.
Invoices can also be used as the basis for enterprises to pay taxes. Enterprises need to pay taxes according to the invoice issuance and sales, and regularly submit invoices and tax returns to the tax authorities. Providing invoices can better prove the business compliance and healthy development of enterprises, and provide effective support for enterprises to apply for financing and evaluate credit.
