In the "Implementation Opinions on Promoting the Work Related to Electronic Labor Contracts (Draft for Comment)" issued by the Beijing Municipal Bureau of Human Resources and Social Security, it is clear that electronic labor contracts should be managed through the electronic labor contract signing information system, and employers can use the signing system provided by the third-party signing service agency (hereinafter referred to as the "third-party signing system") or adopt the mode of self-built and self-use signing system.

(Reassuring endorsement: Most small and medium-sized enterprises do not need to build their own systems, but can directly cooperate with third-party institutions. Small and medium-sized enterprises can save development and software maintenance costs by cooperating with third-party organizations, and third parties can also provide standardized solutions.
