30-second answer

An open procedure is a competitive route in which any interested supplier may submit a tender, subject to the published requirements and applicable procurement regime.

Detailed explanation

The open procedure allows broad market participation because suppliers do not pass through a separate shortlisting stage before tendering. All bidders generally submit the required selection, quality and pricing information by the stated deadline.

Open access does not mean simple entry. The buyer may still apply conditions of participation, exclusion checks, mandatory gateways, minimum standards and detailed quality evaluation. Competition can also be intense because every capable supplier can respond.

Suppliers should assess the full cost of bidding and their realistic differentiation. A disciplined compliance matrix, evidence plan and bid/no-bid decision are essential where the field may be large.

Why it matters

It can provide broad access but may attract substantial competition.

How buyers use it

The buyer uses an open procedure to invite tenders from the wider market and evaluate all compliant submissions under the published method.

What suppliers should do

  1. Confirm which legal regime governs the procurement.
  2. Review every participation and gateway requirement.
  3. Assess likely competition and bid cost.
  4. Plan sufficient resource for a full submission.
  5. Submit all selection, quality and pricing information together as instructed.
