After obtaining the business license, the company needs to complete a series of administrative procedures and management measures to ensure that the company can operate legally and comply with relevant laws and regulations. Here are some things that companies must do:

1. After the establishment of the company, it is necessary to engrave the official seal, financial seal, legal person seal, contract seal, invoice seal and other seals. These seals are the basic tools for the company's office and business operations, and must be strictly controlled. In particular, the management and supervision of the official seal and financial seal should be strengthened to avoid economic losses and legal disputes caused by the loss or improper use of the seal.

2. Opening a basic bank account is a necessary option for companies. To open a bank account, you need to provide the company's business license, legal person ID card, legal person power of attorney and other documents. After opening an account, the company can use this account for daily fund collection, payment, settlement and other businesses. In addition, the company can also handle financial services such as loans and bill acceptance through this account.

3. Tax registration is required after the establishment of the company. Tax registration refers to registering the company's tax information with the national tax department and obtaining tax registration certificates such as taxpayer identification number. Tax registration is a prerequisite for a company to obtain normal tax qualification, and it is also the basis for opening business licenses and bank accounts.

4. Bookkeeping and tax declaration companies need to conduct bookkeeping and tax declaration in the operation process. Bookkeeping and tax declaration refers to the timely and accurate recording and reporting of the financial status and tax payment of enterprises in accordance with the provisions of the tax authorities. In order to avoid the daily operation of the enterprise being affected by the tedious bookkeeping and tax declaration work, it is recommended to entrust a professional financial and tax agent company for bookkeeping and tax declaration.

5. Sign tripartite agreements with tax bureaus, banks and enterprises In order to avoid disputes and responsibilities caused by improper operations, the company must sign tripartite agreements with tax authorities, banks and enterprises, and properly keep the contents of the agreements. The contents of the tripartite agreement usually include tax treatment, banking business treatment, enterprise operation management, etc., which must be strictly implemented.

In addition to the above points, the company also needs to consider human resource management, intellectual property protection, risk management and other aspects. The company should establish a sound management system and process to ensure the legal and compliant operation of the company.
