Open Procedure

The open procedure is the most common public procurement procedure in the European Union and most modern procurement frameworks. Under the open procedure, any qualified supplier can submit a tender directly in response to a published contract notice without first passing a pre-qualification stage. The procedure is named open because the door to participate is open to all interested suppliers from the start. The open procedure is the default choice for routine procurements where the buyer expects competitive interest from a known market.

How the open procedure works

The open procedure begins with the publication of a contract notice. The notice contains all the information needed for suppliers to assess the opportunity and prepare a tender, including the contract subject matter, estimated value, evaluation criteria, and submission deadline. The notice is accompanied by the full tender documents, which suppliers can download and review.

Suppliers who decide to participate prepare and submit their tenders by the deadline. There is no separate qualification stage. Each tender is evaluated as a complete package, covering both the supplier's qualifications and the substantive offer. The contracting authority opens all submitted tenders after the deadline, evaluates them against the published criteria, and selects the winner.

Standard timelines for open procedures are defined by EU directives and national rules. For above-threshold contracts in the EU, the minimum tender period is 35 days from the publication of the contract notice. This can be reduced to 15 days if a Prior Information Notice was published earlier or to 10 days in genuine cases of urgency. Most open procedures in practice run for 35 to 60 days, allowing suppliers reasonable time to prepare quality bids.

When the open procedure is the right choice

The open procedure is suitable for most standard procurements where the buyer expects multiple qualified suppliers in the market. The procedure is straightforward, transparent, and predictable. Buyers know what to expect and suppliers know how to participate. The open procedure also delivers strong evidence of competition because anyone can bid, satisfying both legal requirements and political optics for public spending.

The open procedure is less suitable when the supplier market is highly specialised or includes few qualified participants. In such cases, the open procedure can attract many low-quality bids that consume evaluation resources without producing meaningful competition. The open procedure is also less suitable for very complex contracts where the buyer needs to interact with bidders during the procurement to refine requirements. Complex procurements typically use restricted procedures, competitive dialogue, or negotiated procedures instead.

Cost considerations also influence the choice. The open procedure is generally cheaper for the buyer to administer because there is no separate qualification stage. The procedure is more expensive for suppliers in aggregate because all interested suppliers prepare full bids without prior screening. In specialised markets where each bid is expensive to prepare, the open procedure can be wasteful from the supplier perspective.

How suppliers approach the open procedure

Suppliers approach the open procedure with a clear bid-or-no-bid decision early in the process. Because there is no qualification stage to filter the field, the supplier must decide quickly whether to commit resources to a full bid or to skip the opportunity. The decision rests on the strategic fit, the win probability, the contract value, and the resources required to prepare a competitive submission.

Once committed, suppliers prepare a complete tender that addresses both qualification criteria and substantive evaluation criteria. The full tender package is typically more elaborate than what would be needed in a restricted procedure, where qualification is assessed separately. This means that suppliers in open procedures invest more upfront effort but face less procedural complexity.

Different EU member states show different patterns of open procedure usage. Some countries with mature procurement systems use the open procedure for the substantial majority of above-threshold contracts. Others rely more heavily on restricted procedures or framework agreements, which involve qualification stages or master contracts. The trend in recent years has been a slight decline in pure open procedures and a corresponding increase in framework agreements, which combine some elements of qualification with subsequent mini-competitions.
