What qualifications do human resources companies need to pay social security for enterprises or individuals?

At present, companies in the general human resources service industry are legal. First of all, we need to confirm the company qualification. Only after the government's certification and permission can we have relevant operational qualifications. There are three necessary documents: business license, human resources service license and labor dispatch business license. These three certificates are required by social security agencies, and the relevant business qualifications of enterprises can be inquired through the national enterprise credit information publicity system.
