Public procurement in Spain moves over 200,000 million euros per year according to data from the Public Sector Contract Registry. Yet the vast majority of that volume goes to medium-sized and large companies that have been working with the Administration for years. An SME approaching a public tender for the first time encounters a dense process, full of acronyms and deadlines that wait for no one. This article breaks down that barrier to entry: what a public tender is, what types exist, what documentation is required and the most common mistakes companies make on their first bid.
What is public procurement and why should SMEs care
Public procurement is the mechanism by which public Administrations (the State, Autonomous Communities, Provincial Councils, Local Councils, public bodies and dependent organisations) acquire goods, services or works financed with public funds. The current legal framework in Spain is Law 9/2017 on Public Sector Contracts (LCSP), which transposes European directives 2014/23/EU, 2014/24/EU and 2014/25/EU and has been amended several times since it came into force.
The law explicitly reserves part of public procurement for SMEs and micro-enterprises: reserved contracts under Article 99 LCSP, division into lots (Article 99.3 LCSP), simplified solvency requirements for lower-value contracts, and facilitation measures from the Draft Law amending the Law on Public Sector Contracts processed in the Cortes in 2024-2025. The objective is clear: more competition, more suppliers and less dependence on large operators.
For a well-managed SME, winning a public contract offers advantages that the private market rarely guarantees: regulated payment terms (the Administration is legally required to pay within 30 days under Law 3/2004 on measures to combat late payment), multi-year contracts that provide income stability and a public-sector reference that opens doors in the private sector.
Types of procedure: which one applies to your company
Not all public contracts work the same way. The LCSP establishes several procedures depending on the estimated value of the contract and its subject matter. Knowing which one applies is the first step to understanding whether you can participate and under what conditions.
| Procedure | Indicative threshold (services/supplies) | Mandatory publication | Minimum tender period |
|---|---|---|---|
| Minor contract | Up to 15,000 € (supplies/services) / 40,000 € (works) | No (with exceptions) | Not applicable |
| Abbreviated simplified procedure | Up to 60,000 € (goods and services) | Public Sector Procurement Platform | 10 working days |
| Simplified procedure | Up to 221,000 € (services, below European threshold 2024-2025) | Public Sector Procurement Platform | 15 working days |
| Open procedure | Above European thresholds | OJEU + National platform | 35 days (electronic tender) |
| Restricted / negotiated procedure | Variable, with justification | Prior notice or without publicity | 30 days (restricted) |
| Competitive procedure with negotiation | Same as open, with complex qualitative criteria | OJEU + National platform | 30 days |
Note on 2024-2025 thresholds: the European Commission revised public procurement thresholds through Delegated Regulation (EU) 2023/2495, effective from 1 January 2024. For service and supply contracts awarded by classic public sector entities, the threshold requiring publication in the Official Journal of the European Union (OJEU) was set at 221,000 euros (previously 214,000 €). For works contracts, at 5,538,000 euros. Spain incorporated these thresholds through Ministerial Order HAC/1137/2023 of 8 November 2023. Always check the current table on the Ministry of Finance website before classifying your procedure.
Where to find tenders: key platforms and tools
The main entry point for finding public contracts in Spain is the Public Sector Procurement Platform (PLACE), managed by the Ministry of Finance, accessible at contrataciondelestado.es. Since 2018, the law requires all contracts above the threshold to be published on this platform, and many Administrations also publish lower-value contracts there. In addition to PLACE, it is worth monitoring:
- Official Journal of the European Union (OJEU) — TED (Tenders Electronic Daily): contracts above the European threshold. Accessible at ted.europa.eu.
- Regional official gazettes (BOCyL, BOCA, BOCM…): many Autonomous Communities also publish their contracts in their official bulletins.
- Contracting profiles of specific entities: each body is required to maintain a published contracting profile, accessible from the body's website or from PLACE by filtering by entity.
- Private aggregators: services such as Vortal, Axesor Licitaciones or similar offer personalised alerts by CPV code (product/service code), autonomous community and contract value. Useful for companies that tender regularly.
The key to not missing calls for tender is to set up alerts by CPV code. The Common Procurement Vocabulary is the European nomenclature for products and services used by the Administration to classify contracts. Identify the CPV codes that correspond to your activity and set up alerts on PLACE and TED; you will receive an email each time a contract with that code is published.
Requirements to tender: solvency and professional authorisation
Before submitting a bid, the company must demonstrate that it meets the eligibility requirements set out in the LCSP. These requirements are grouped into three areas:
1. Legal capacity and professional authorisation
The company must be lawfully established in Spain or in a EU member state, and its corporate purpose must include the activity that is the subject of the contract. In some sectors (construction, healthcare, private security, transport…), a specific professional or business authorisation is also required: contractor classification, registration in sector-specific registers, operating licences, etc. Check the Particular Administrative Clauses Document (PCAP) for each tender: it lists exactly what the contracting authority requires.
2. Economic and financial solvency
The Administration needs to ensure that the successful tenderer has the financial strength to execute the contract. The most common criteria are: minimum turnover over the past three financial years (normally 1.5 times the estimated contract value), a solvency ratio, or holding professional indemnity insurance up to a minimum sum. For low-value contracts (abbreviated simplified procedure) the requirement is reduced or even waived, facilitating access for micro-enterprises.
3. Technical or professional solvency
The company must demonstrate that it has the experience and means to carry out the contract correctly. The most common mechanisms are: a list of contracts executed in the past three to five years similar to the contract subject matter (with satisfactory performance certificates), qualifications of the technical team, description of the staff dedicated to the project, quality certifications (ISO 9001, ISO 14001…) or adherence to recognised management systems. If your company is new or has no prior experience in public procurement, forming a Temporary Business Association (UTE) with a more experienced partner is a way to meet solvency requirements without meeting them individually.
Documentation: what goes in each envelope
Electronic bids on PLACE are usually structured in two or three envelopes (on the platform these are called «electronic envelopes» or «parts of the bid»). The most common structure in an open procedure is:
- Envelope A — Administrative documentation: legal capacity (deed of incorporation, notarial powers of attorney), declaration of compliance (ESPD or the contracting authority's own model), certificates confirming no grounds for exclusion, and in some cases a provisional guarantee.
- Envelope B — Award criteria assessed by value judgement: technical proposal, work plan, proposed improvements. This is opened and assessed before the financial offer is known, to prevent price from influencing the technical evaluation.
- Envelope C — Award criteria assessed automatically: financial offer, quantifiable proposals (delivery time, additional warranty, emissions reductions…).
The European Single Procurement Document (ESPD) has simplified the administrative burden of Envelope A since 2017: instead of submitting all certificates from the outset, the company declares that it meets the requirements. Only the tenderer about to be awarded the contract needs to actually substantiate its declarations with the original documents. The official tool for completing the ESPD in XML format is available on the EU single market portal.
The technical proposal: where tenders are won or lost
The most widespread mistake among SMEs tendering for the first time is spending 80% of their time on the financial offer while barely reviewing the technical proposal. In practice, for service contracts, the technical score typically accounts for between 40% and 70% of the total score. Winning on price while losing on technical quality is mathematically impossible when the weighting is balanced.
A winning technical proposal typically includes:
- A precise understanding of the subject matter of the contract (demonstrating that you have read the technical specifications, not that you are offering a generic service).
- A detailed methodology adapted to the specific context of the contracting authority.
- The project team with names, qualifications and specific dedication to the contract (not a generic corporate organogram).
- A work plan with milestones, deliverables and monitoring mechanisms.
- Improvement measures beyond the minimum required (improvements score only if the specifications include them as a criterion; if not, do not include anything that raises the price without scoring).
- Previous experience with similar contracts, with client names and measurable results where possible.
If your company needs support in structuring and drafting competitive technical proposals, our public tender consultancy team works with you from reading the specifications through to submitting the bid, covering risk analysis, technical argumentation and legal-administrative review.
Most common mistakes made by SMEs on their first tender
Years of supporting companies through public procurement processes reveal recurring patterns of error. These are the most costly:
- Not reading the PCAP in full before deciding to tender. The administrative clauses define the award criteria, the solvency requirements, grounds for exclusion and automatic disqualification. Tendering without having read it is a waste of resources.
- Signing with the wrong certificate. The electronic signature of the company's representative must match exactly the notarial powers of attorney submitted. An employee certificate without notarial authority is enough to get the bid excluded.
- Submitting the financial offer in the wrong envelope. If the price appears in Envelope B (value judgement), the evaluation committee will exclude the bid for breaking the anonymity of the technical assessment.
- Submitting an abnormally low price without justification. The LCSP (Article 149) requires the committee to identify bids presumed to be abnormally low. If your bid exceeds the abnormality thresholds in the specifications, you have the right to justify it, but if you fail to do so correctly you will be excluded.
- Not declaring subcontracting properly. If you are going to subcontract part of the contract, you must declare it in the bid (Article 215 LCSP). Undisclosed subcontracting after award may lead to termination of the contract.
- Ignoring the execution phase. Winning the contract is just the beginning: amendments, extensions, penalties for non-compliance and payment certifications all have their own rules. Document everything from day one.
The UTE as a strategy for entering the public market
The Temporary Business Association (UTE), regulated under Law 18/1982, is the most agile vehicle for two or more companies to tender together without forming a new legal entity. In public procurement, the UTE makes it possible to:
- Pool the economic and technical solvency of several companies to meet the thresholds required by the specifications.
- Combine complementary specialisations (for example, a consultancy firm and a technology company for a digital transformation contract).
- Share the contract risk between the partners according to their participation percentage.
The formal constitution of the UTE is formalised before a notary before the contract is signed (at the bid stage, a notarial commitment to constitute it if awarded is sufficient). Each company is jointly and severally liable for obligations to the Administration, so a shareholders' agreement between the partners regulating internal management, contributions and revenue distribution is essential.
How to improve your score in successive tenders
Tendering is a skill that improves with practice and with the systematic analysis of results. After each process, regardless of the outcome, it is advisable to:
- Request the evaluation report (Article 151.4 LCSP): an unsuccessful tenderer has the right to know their own scores and those of the successful tenderer. It is the only way to find out exactly which criterion you lost on and by how much.
- Review contracts won by competitors: once formalised, the contract is public information. You can download the contract award notice from PLACE to find out the awarded price, winning company and number of tenderers.
- Keep your solvency portfolio up to date: satisfactory performance certificates, team qualifications, quality certifications. If Summum Consultoria is already supporting you in your public procurement process, the solvency portfolio is kept organised and ready to reuse in future calls.
- Build a library of reusable texts: sections such as the company description, general methodology or environmental measures can be standardised and adapted for each contract, saving time on each bid.
Mandatory registers: ROLECE and contractor classification
The Official Register of Tenderers and Classified Companies of the Public Sector (ROLECE), managed by the Ministry of Finance, allows companies to register their legal capacity, representation and accredited solvency centrally. Once registered, the company does not need to submit those documents with each tender: the evaluation committee can verify them directly in the register.
Contractor classification (groups, subgroups and categories under Royal Decree 1098/2001) is mandatory for works contracts above 500,000 euros and service contracts above 200,000 euros in certain activity groups. Classification is granted by the State Advisory Board on Public Procurement or the equivalent regional boards. For SMEs starting out, classification is generally not required for initial contracts; it is worth obtaining before tendering for higher-value contracts.
Frequently asked questions
Can a sole trader submit a bid for a public contract?
Yes. The LCSP does not require the tenderer to be a commercial company. A self-employed individual acting as a sole trader can submit bids provided their economic activity matches the subject of the contract and they meet the solvency requirements of the specifications. In practice, economic solvency requirements (minimum turnover) tend to rule out sole traders in high-value contracts, although for low-value abbreviated simplified procedures it is perfectly viable.
What is the Evaluation Committee and what role does it play?
The Evaluation Committee (Mesa de Contratación) is the collegiate body that assists the contracting authority during award procedures. It is responsible for opening the envelopes, verifying administrative documentation, submitting the proposal for ranking bids to the contracting authority and, where applicable, requesting justification for abnormally low bids. It does not award contracts itself: it proposes. The award decision is taken by the contracting authority (mayor, regional minister, head of the body…). Understanding how it operates is important because deadlines for correcting documentation are set by the Committee, and its criteria are binding at the administrative stage.
How long does a procurement process take from publication to payment?
It depends on the procedure, but in a standard open procedure the full cycle can exceed six months: the period for submitting bids (minimum 35 days), technical assessment (weeks), the proposed award and the objection period (10 working days), contract formalisation (15 working days from notification) and execution of the first deliverable. The first payment does not arrive until the completed work is certified. It is essential to plan cash flow before tendering for significant contracts.
What happens if I unintentionally submit an abnormally low bid?
The LCSP sets abnormality thresholds that vary depending on the number of bids: if there are more than five tenderers, a bid is presumed abnormally low if it is more than 25% below the average of all bids. If you exceed that threshold, the committee will ask for a written justification. If you can demonstrate that your bid is viable (cost structure, subcontractor commitments, process efficiencies…), you may maintain it. If you do not justify it, or the justification is insufficient, you will be excluded even if you had the lowest price. Before submitting a very aggressive price, calculate the abnormality thresholds using the previous year's figures.
Can I challenge the outcome of a procurement process?
Yes. If you consider that the award is incorrect, the LCSP provides for a special remedy in procurement matters before the Central Administrative Court for Contractual Remedies (TACRC) or the equivalent regional tribunal for contracts above certain thresholds (100,000 € in services/supplies, per Article 44 LCSP). The remedy automatically suspends the award until the tribunal rules (in theory within 15 working days). For lower-value contracts, the ordinary administrative appeal before the contracting authority itself is the route. The success rate of well-founded remedies is significant: it is worth at least requesting the evaluation report before deciding whether to appeal.
