Country kit

Bidding in Spain: the country kit

What a company from another country needs to know before it bids for a public contract in Spain.

Not legal advice. Rules and portals change: check the buyer's documents and the official portal.

For a bidder from abroad

What a company from another country usually runs into. Each line names where you can check it.

Portals

Most buyers publish and take bids on the State platform, PLACSP. Some autonomous communities, Catalonia and the Basque Country among them, run their own, and the notice says which one applies. On PLACSP the bid is prepared with the platform's own tool.

Getting the documents

The procurement documents can usually be downloaded without an account. Sign in anyway: only a registered reader is told when the buyer changes them or answers a question.

Account to submit

To submit you need an account on the platform the notice names. Open it days ahead: some platforms check a new company by hand.

Electronic signature

A qualified electronic signature is usually required on the bid, or on the files the documents name.

A qualified signature from a provider established in another EU state has the same legal effect (eIDAS Regulation, Article 25). Whether the platform's own tool reads your certificate is a practical matter: try it well before the deadline.

ESPD and eCertis

The European Single Procurement Document is accepted as a first proof that you are suitable; here it is called DEUC (documento europeo único de contratación). eCertis shows which certificates of your own country match the ones asked for.

Registers and lists

Registration in ROLECE, the State's register of bidders, is usually asked for in the simplified open procedure (procedimiento abierto simplificado); a company from another EU state can usually rely on its own country's official list or on the ESPD instead. The classification asked of Spanish contractors for larger works is not asked of companies from other EU states, which prove their standing by other means.

Language of the bid

Bids are usually written in Spanish. Certificates in another language usually need a translation; the documents say whether it has to be certified.

The periods are the ones for contracts above the EU thresholds. Below them national rules differ, and some awards have no standstill at all.

Working days are counted with national holidays only. Regional and local holidays can move the real day later.

On the page of an awarded notice the periods are counted from its award date, with a letter asking the buyer for its reasons. Awarded contracts in Spain
