1. Attachment List (Supplement Core Details)

In ecommerce cooperation, many details cannot be detailed in the main contract and need to be supplemented through attachments. Common attachments include:

Product List (including name, specifications, unit price, and quality standards);

Service Standard Manual (including KPI indicators and service processes);

Logistics Service Agreement (if involving third-party logistics);

Confidentiality Agreement (if detailed confidentiality obligations are required);

Qualification documents of both parties (copies of business license and permit, stamped with official seal).

Note: The attachment must be marked as "having the same legal effect as this contract" and confirmed by both parties' signatures and seals.

2. Sign the standard (to ensure the effectiveness of the contract)

Signature and Seal: Both parties' legal representatives/authorized representatives must sign and affix the company seal (or contract specific seal). Branch offices must affix the branch office seal and provide a letter of authorization from the head office;

Signing format: Paper contracts require each party to hold one copy (or three copies, with a third party retaining one copy), while electronic contracts must be signed through legally effective electronic signature platforms (such as e-signature treasure and Fada) to avoid using invalid forms such as "screenshot stamping" and "scanned signature";

Contract custody: It is recommended that both parties keep both paper and electronic versions of the contract, with the electronic version encrypted to avoid loss or tampering.
