What is
supplier selection
Also known as: shortlisting, selection of candidates
Supplier selection is the process by which a contracting authority narrows down the pool of qualified candidates to a limited number who are invited to submit tenders. It is a key step in restricted procurement procedures where not all interested economic operators participate in the tender phase.
How does supplier selection work?
The process takes place in two stages. First, the contracting authority assesses whether candidates meet the qualification requirements — such as financial standing, technical capacity, and professional experience. Among those who qualify, the authority then selects a shortlist based on pre-defined selection criteria.
Selection criteria must be objective, non-discriminatory, and verifiable. The contracting authority may choose the candidates with the best overall qualifications for the specific procurement, or aim for a mix that ensures strong competition dynamics — for example, by selecting a combination of small, medium-sized, and large operators.
When is supplier selection used?
Supplier selection applies under the following procedures in EU/EEA public procurement:
- Restricted procedure — minimum 5 candidates
- Competitive procedure with negotiation — minimum 3
- Innovation partnership — minimum 3
- Competitive dialogue — minimum 3
These minimum numbers are set out in EU Directive 2014/24/EU (Articles 65–66). The contracting authority may specify a range — for example, five to seven candidates — and is not required to select the maximum number as long as the decision is objectively justified.
The authority must promptly notify candidates who are not selected, providing a brief statement of reasons. Tools like Cobrief can help suppliers track restricted procedures and prepare documentation that strengthens their chances of being shortlisted.
Supplier selection balances efficiency with competition. By limiting the number of tenderers, contracting authorities reduce the burden of tender evaluation, while suppliers benefit from improved odds when fewer competitors are vying for the same contract.
