What is Single-Stage Procurement?
Single-stage procurement (einstufiges Vergabeverfahren) refers to procurement procedures in which the entire process is conducted in a single phase. Bidders submit their complete bids, including all suitability evidence, technical proposals, and pricing, in one submission without a prior participation or prequalification phase. The contracting authority evaluates all aspects of the submission together and awards the contract based on the predefined criteria.
The most prominent example of a single-stage procedure is the open procedure (offenes Verfahren) above the EU thresholds and the public tender (oeffentliche Ausschreibung) below the thresholds. In these procedures, the contract notice is published, all interested companies receive the tender documents, and any company that considers itself suitable may submit a bid. The contracting authority then evaluates the bids in terms of both suitability and the award criteria.
The single-stage approach offers several advantages. It is generally faster because there is no separate qualification phase, which can save weeks or months compared to multi-stage procedures. It is also more straightforward for both contracting authorities and bidders, as the entire process follows a linear sequence from publication to award. However, it can result in a large number of bids, increasing the evaluation effort, and may not be suitable for complex procurements where early dialogue with the market is beneficial.
Why It Matters for Bidders
In single-stage procedures, bidders must present a complete and compelling package in their initial submission. There is typically no opportunity for clarification, negotiation, or adjustment of the bid content. This places a premium on thorough bid preparation, including careful reading of all tender documents, meticulous compliance with formal requirements, and a clear presentation of qualifications, technical approach, and pricing.
Because all interested companies can participate in single-stage procedures, the competition is typically broader than in multi-stage procedures. Bidders should factor in the likely number of competitors when developing their pricing strategy and should focus on differentiating their offers through quality, innovation, or added value rather than relying solely on price competition.
Legal Framework
The open procedure as the primary single-stage procedure is regulated in Section 15 VgV for above-threshold procurement. The public tender under the UVgO serves as the below-threshold equivalent. For construction works, VOB/A Section 1 Paragraph 3 (1) governs the public tender. EU Directive 2014/24/EU Article 27 establishes the framework for the open procedure at the European level.
