1, reach a cooperation. After the zero-declaration enterprise has the service demand of agency bookkeeping, it is necessary to distinguish and choose the agency bookkeeping companies in the market, determine the cooperative institutions, and sign a formal agency bookkeeping service contract with them. Define the service content, charging standard, rights, responsibilities and obligations of both parties in the contract to avoid unnecessary disputes during the subsequent accounting treatment. The existence of agency bookkeeping service contract can protect the rights and interests of both parties.

2. Receive the voucher. After the two parties sign the contract, the agency bookkeeping company can start to provide bookkeeping and tax return services for the zero-declared enterprises. During this period, the entrusted enterprises need to provide relevant documents and materials according to the requirements of the agency bookkeeping company, and provide the bills and vouchers generated during the operation on time, so as to provide the necessary basis and bill basis for the agency bookkeeping accounting to handle the financial work of enterprises.

3. Account processing. After obtaining the enterprise bills, the accountants of the agency bookkeeping company should review and sort them out, prepare accounting vouchers, and then they can make accounts. After the accounting is completed, financial and tax statements will be prepared for the enterprise, and tax telegrams will be sent for the enterprise according to the data on the tax report. If the enterprise meets the requirements of zero declaration, it needs to declare, although it does not need to pay taxes.

4. Tax declaration. That is, to complete tax payment and declaration for enterprises. Nowadays, most bookkeeping companies report online, but if they need to go to the tax department for on-site handling, the accountants of the bookkeeping company will also go to the tax hall to do the agency for the enterprise. Then, after the declaration is completed, return the financial and tax information to the entrusted enterprise and make arrangements for the next stage of work.
