To understand the difference between invitational bidding and competitive consultation, we must first clarify that although these two procurement methods belong to the scope of bidding, the implementation steps and conditions are different.
The first difference is how suppliers are invited. Public bidding is a broad invitation to unspecified suppliers to participate in bidding, usually with a public bidding announcement. Competitive negotiations and consultations are more flexible. Suppliers can be recommended by purchasers or review experts, or randomly selected from the provincial supplier database, increasing the diversity of participants.
Secondly, the date regulations for document issuance are also different. The bidding document release period for public bidding requires at least 20 days, providing suppliers with sufficient time to prepare; the period of competitive negotiation is shorter, and it generally takes at least 3 working days from the issuance of the document to the submission of the first response document; competitive negotiation It requires a shorter period of time, at least 10 days for the supplier to respond.
In general, public bidding is more transparent and open, while competitive negotiations and consultations pay more attention to efficiency, and sometimes the process is adjusted according to the actual situation. Through these differences, purchasers can flexibly choose a suitable procurement method based on project needs and actual conditions.
