Public Tender
A public tender is an administrative procedure through which public sector entities — such as municipalities, ministries, or state-owned companies — procure services, works, or supplies through open participation by companies.
This process ensures transparency, free competition, equal treatment, and efficiency in the use of public resources.
How does it work in Spain?
Tenders are regulated by Law 9/2017 on Public Sector Contracts, which adapts European directives on public procurement.
The process is divided into several stages:
- Preparation of the file: drafting of technical and administrative specifications.
- Publication: announcement on official platforms such as the Public Sector Contracting Platform.
- Submission of offers: companies submit their proposals within the deadline.
- Evaluation and award: technical and financial analysis of the offers.
- Formalization: signing and execution of the contract.
Types of procedures
- Open: any company can participate.
- Restricted: only pre-selected companies may submit bids.
- Negotiated: negotiation takes place directly with one or more suppliers.
- Competitive dialogue: ideal for complex contracts, with prior dialogue between the administration and bidders.
Why participate?
Participating in public tenders opens the door to stable and recurring economic opportunities. In addition, it positions your company as a trusted supplier to public institutions.
This is especially valuable if you offer sustainable or innovative solutions, as more and more tenders include environmental and social criteria.
