Can a branch sign a contract with the winning company?

Legal analysis: it is impossible for a branch to sign a contract with the head office, which does not conform to the bidding law. When a branch company wins the bid, it can only sign a contract with the tendering unit. If it is changed to the head office, it means that the subject of the contract has changed, which is the transfer of the winning project to a certain extent, which is not allowed by law. Although branches are not independent legal persons, they are generally licensed, and can engage in business activities and sign contracts with foreign countries within the scope authorized by the head office. And you can sign the contract in your own name, that is, you don't necessarily need to stamp the official seal of the head office, just stamp the official seal of the branch office.

Legal basis: Article 48 of the Bidding Law of People's Republic of China (PRC), the winning bidder shall fulfill his obligations in accordance with the contract and complete the winning project. The winning bidder shall not transfer the winning project to others, nor shall it dismember the winning project and transfer it to others separately. The winning bidder may, according to the contract or with the consent of the tenderer, subcontract part of the non-major and non-critical work of the winning project to others for completion. The person who accepts subcontracting shall have corresponding qualifications and shall not subcontract again. The winning bidder shall be responsible to the tenderer for the subcontracted project, and the subcontractor shall be jointly and severally liable for the subcontracted project.
