e-Procurement Procedures

Supported Electronic Procurement Procedures

The e-PPS platform is designed to cover the needs of Contracting Authorities for the establishment of e-Procurement systems. In this respect, all functionality supported by e-PPS has been developed in line with all applicable EU legislation (e.g. Directives 2004/17/EC and 2004/18/EC as amended to Directives 2009/81/EC and 1336/2013). E-PPS also covers the most important rules in public procurement internationally (e.g. World Bank, WTO-GPA, UNCITRAL, etc.).


The open procedure is defined as the procedure "whereby any interested Economic Operator may submit a tender". It is the only procedure under which any interested Economic Operator can participate by submitting a tender, without the Contracting Authority performing a prior selection and/or dispatching an invitation.


The restricted procedure is defined as the procurement procedure in which "economic operator may request to participate and whereby only those economic operators invited by the contracting authority may submit a tender".

Negotiated (with advertisement)

The negotiated procedure is defined as the procurement procedure in which "the contracting authorities consult the economic operators of their choice and negotiate the terms of contract with one or more of these".

The negotiation process enables Contracting Authorities to negotiate the terms of the contract. The process is similar to the restricted procedure but it foresees the further reduction of candidates. The reduction of candidates should be performed on the basis of objective criteria indicated in the contract notice.

Negotiated (without advertisement)

The Negotiated procedure may also be applied without prior advertisement. In this case, this procedure entails similar steps and procedures as in the Negotiated procedure (with advertisement), with the main difference that the Contracting Authority directly invites at least three (3) Economic Operators instead of publishing a Contract Notice.

Competitive Dialogue

Competitive dialogue is defined as the procurement procedure in which “any economic operator may request to participate and whereby the contracting authority conducts a dialogue with the candidates admitted to that procedure, with the aim of developing one or more suitable alternatives capable of meeting its requirements, and on the basis of which the candidates chosen are invited to tender”. The Competitive Dialogue procedure was designed as an alternative to the Negotiated procedure for particularly complex projects. The underlying concept of the competitive dialogue is to give to the Contracting Authority the option to further discuss the contract specifications with potential tenderers.

Framework Agreement

The Framework Agreement is defined as "an agreement between one or more contracting authorities and one or more economic operators, the purpose of which is to establish the terms governing contracts to be awarded during a given period, in particular with regard to price and, where appropriate, the quantity envisaged".


Considering the award of low-value contracts, they can be awarded using the Simplified procedure. In this procedure, Contracting Authorities do not publish a contract notice. Instead, given a specific procurement objective, they invite a minimum number of Economic Operators to join the competition.

Electronic Auctions

The electronic auction is defined as "a repetitive process involving an electronic device for the presentation of new prices, revised downwards, and/or new values concerning certain elements of tenders, which occurs after an initial full evaluation of the tenders, enabling them to be ranked using automatic evaluation methods."

Electronic auctions are considered as an extension to the procedures for one-off or repetitive contracts. They do not constitute stand-alone procedures by themselves, but rather can be used as extensions of other procedures for obtaining improved offers.
