How to prepare a competitive bid for a public tender

Winning a public tender doesn't depend on price alone. It depends on understanding the tender document, avoiding the mistakes that disqualify you and arriving with a solid proposal before the closing time.

1. Decide whether it's worth taking part

Before investing hours in putting a bid together, assess the tender with judgment:

Does the scope fit what you actually do well?
Can you meet the eligibility requirements without forcing anything?
Does the estimated amount justify the effort, given your margin?
Do you have a history of awarded prices for something similar? If the reference range is far below your cost, it may not be your tender.

Saying "no" early to the wrong tenders leaves you resources to compete seriously in the right ones.

2. Read the whole tender document, twice

Most bids are lost because they weren't read carefully. Pay attention to:

Technical specifications: every required feature is a box you must tick and prove.
Eligibility documents: sworn statements, certifications, financial statements, minimum experience. If one is missing, the bid can be excluded without being evaluated.
Evaluation system: how the points are split. If price weighs 70% and delivery time 30%, your strategy is different from when experience weighs 40%.
How to quote: currency, whether the price includes taxes or not, units, whether it is awarded by line item or as a whole.

3. Use the question period

If something in the tender document is ambiguous, contradictory or seems tailored to another supplier, raise it as a formal question within the deadline. The administration's answers are binding and can clarify —or even correct— conditions that put you at a disadvantage. Don't assume: ask.

4. Set the price with data, not intuition

Price is almost always the factor with the most weight. To get it right you need two things: to know your real cost (with margin) and to know the market.

In public procurement, the market is transparent: previous awards are public information. Reviewing the prices at which equivalent goods or services were awarded in recent months gives you a realistic range. If you quote far above it, you lose points; if you quote far below, you compromise your margin or risk being asked to justify a ruinously or excessively low price.

Where to find reference prices

You can rebuild that range by hand, going through the files of previous tenders in SICOP. Or you can use a tool that already has it organized: LicitaSmart shows you historical prices by type of good or service and the details of the winning bids analyzed. See also the guide reference prices: how to use the award history.

5. Look at the competition

Knowing who else usually bids in your sector helps you calibrate. Does the same supplier always compete and win on price? Are there tenders where few people bid? That competitor analysis changes where you put your effort.

6. Put the package together and submit it with time to spare

Check the eligibility boxes one by one against a checklist.
Make sure the bid bond, if required, is issued correctly and for the exact amount.
Confirm validity dates: certifications, proof of legal representation, financial statements.
Upload the bid hours in advance, not minutes. Technical and digital signature problems always show up at the last moment.

Go over the list of common mistakes that disqualify a bid before sending.

7. After the opening

The process doesn't end when you submit. Follow up on any requests to correct your bid, review the award decision and, where appropriate, analyze why your bid won or didn't. That learning is what makes the next one more competitive.
