The procedure of procurement negotiation is divided into several stages.

1. Preparation stage: including collecting procurement negotiation materials, collecting supplier information, making procurement negotiation plans and conducting simulated negotiations. This stage is the basis of procurement negotiation, so it is necessary to make full preparations, understand the market situation and suppliers, and pave the way for subsequent negotiations.

2. Opening stage: In the procurement negotiation, the opening stage is very important. At this stage, it is necessary to clarify the needs and expectations of both sides, determine the main contents and agenda of the negotiations, and lay the foundation for the follow-up negotiations.

3. Formal negotiation stage: this stage is the core of procurement negotiation, mainly focusing on key terms such as price, quality and delivery date for in-depth discussion and negotiation, so as to reach an agreement beneficial to both parties.

4. Closing stage: In the final stage of procurement negotiation, after the two parties reach an agreement on key terms, the contract needs to be signed and closed. At this stage, we should pay attention to the details and terms of the contract to ensure the accuracy of the contract and avoid disputes in the later stage.
