Cannot open in advance. A business license is a document that every operator needs to apply for to do business. Without this certificate, it is operating without a license, which is illegal. Extended information

A business license is a certificate issued by the industrial and commercial administration to industrial and commercial enterprises and self-employed individuals allowing them to engage in certain production and business activities. Its format is uniformly stipulated by the State Administration for Industry and Commerce.

The registration matters are: name, address, person in charge, amount of funds, economic composition, business scope, business method, number of employees, business period, etc. The business license is divided into original and duplicate, both of which have the same legal effect. The original copy shall be placed in a conspicuous place at the company's residence or business premises, and the business license shall not be forged, altered, rented, lent or transferred.

Industrial and commercial enterprises or self-employed individuals without a business license are not allowed to open business, and are not allowed to engrave official seals, sign contracts, register trademarks, or publish advertisements.
