The first step is to see if all the conditions are met. Check the bidding information and winning results for free, and bid with swordfish. If you don't meet the requirements, you can't register, that is, if you register, you may be disqualified in the bidding and evaluation, which is not worth it. After reading the qualification conditions, look at the requirements for purchasing bidding documents, or the conditions for pre-qualification registration and obtaining documents.
Generally, the tendering company will write the contact person, contact information and relevant documents that need to be brought when registering or purchasing documents. For example, business license, power of attorney, copy of ID card, various qualification certificates, safety production certificates and so on. It depends on the project. Besides, there will be a time limit. You must complete the project registration and collect live documents within the time interval. If the time exceeds, it is equivalent to giving up automatically.
