Electronic contract and paper contract have the same legal effect, but in order to meet the relevant legal requirements, it is very complicated, so the third-party electronic signing platform is generally chosen.

The specific signing process is roughly as follows:

1. Choose a reliable third-party electronic signing platform and register for certification (to prove that you are you in the network environment). You can make your electronic signature and company official seal through the platform.

2. Upload the document to be signed, fill in the customer's name and mobile phone number and send it (the signing order of both parties can be customized).

3. The customer receives the short message containing the signature link on the mobile phone short message, and clicks the link to authenticate according to the page prompt to generate the handwritten electronic signature and signature.

The signing of both parties means that the whole contract is signed.
