Advantages and disadvantages of public bidding and invited bidding

Invitation to bid is a kind of bidding method in which a tenderer invites a specific legal person or other organization to participate in bidding by means of an invitation to bid. The difference between this tender method and open tender method is that it allows the tenderer to send invitation letters to a limited number of specific legal persons or other organizations (suppliers or contractors) without issuing a tender announcement.

Therefore, inviting bidding can save bidding cost and improve efficiency. According to the common practice at home and abroad, the prerequisite for adopting the invitation bidding method is to better understand the market supply and suppliers or contractors.

On this basis, we should also consider the specific situation of the project subject to tender:

First, the technology of the project subject to tender is novel, complex or professional, and it can only be selected from a limited range of suppliers or contractors;

Second, the value of the bidding project itself is low, and the tenderer can only achieve the purpose of saving and improving efficiency by limiting the number of bidders. Therefore, invitation is allowed and has great applicability in practice.
