Bidders' conference

A bidders' conference is a briefing held after a buyer issues its solicitation documents. Potential bidders hear about the requirement and the tender or award process, and they can put questions to the buyer's representatives. It is a solicitation-phase activity, which means it happens while suppliers are preparing their bids.

The term is used in defence and public procurement, especially for complex, novel or technically demanding purchases. You may also see it written as bidder conference or pre-bid conference. The purpose is the same in each case: give suppliers a direct channel to the buyer before bids are due.

How buyers use a bidders' conference

The UK Ministry of Defence states that a bidders' conference may be used after contract documents are sent out, to give suppliers an opportunity to ask questions about the tender and award process. UK MOD tendering guidance sets this out as part of conducting the tendering exercise. Other MOD material says a conference gives tenderers an opportunity to ask questions about the requirement, and that conferences are usually used for complex or novel procurements.

NATO takes a similar approach. Its procurement process page says NATO may conduct a bidders' conference depending on the opportunity. The conference is optional for the buyer and is chosen when the opportunity calls for it.

Bidders' conference versus industry day

The two events are often confused, but timing separates them. UK MOD material states that a bidders' conference takes place after tender documentation is issued, while an industry day takes place before it is issued. An industry day introduces a future requirement to the market. A bidders' conference works from documents suppliers already hold.

Related terms include site visit and question-and-answer session. A site visit lets bidders see a location in person, and a question-and-answer session may be a standalone event or part of a conference.

What the NATO Joint Warfare Centre requires of attendees

A NATO Joint Warfare Centre solicitation shows how a conference can be run. It states that the bidders' conference offers potential bidders the possibility of asking questions directly to key personnel. The same solicitation document requires prospective participants to provide identifying information and limits the number of representatives who may attend. Registration and attendance limits are therefore set in the solicitation itself.

Bidders' conferences in Canadian federal practice

Government of Canada records guidance treats the bidders' conference as a normal solicitation activity. Library and Archives Canada's acquisition-services guidance lists "hold bidders conference if required" alongside responding to supplier inquiries and conducting site visits. The same guidance identifies conference agendas and minutes as procurement records, so the buyer keeps a formal record of what was presented.

Accessibility is also part of the picture. The Canadian Accessible Procurement Standard, CAN/ASC-41, includes a section titled "Planning a bidders conference" and requires bidders' conferences to comply with its applicable consultation and accessibility clause. The bidding and contract award section of CAN/ASC-41 sets out these expectations.

What a bidders' conference means for your bid team

Treat the conference as a source of direct access to the buyer, and plan for it as you would any other bid task. Practical steps include:

• Check the solicitation to see whether a conference is offered or mandatory.
• Follow the stated registration and attendance instructions, including any limit on representatives.
• Submit questions through the channel the solicitation specifies.
• Review any official answers or amendments issued afterward, since these update the bid requirements.

Attendance rules are set by each solicitation, so read the notice closely before you decide who attends.
