5 mistakes that can get your bid rejected and how to avoid them
Submitting a bid in public procurement is not only a sales exercise. It is also a legal process where small details can determine whether your bid is evaluated or rejected.
Many suppliers lose contracts not because their offer is weak, but because they misunderstand how procurement requirements are interpreted and applied in practice.
To better understand where suppliers often go wrong, we spoke with procurement lawyers from MAQS Advokatbyrå, who regularly advise companies involved in public tenders.
Many suppliers read tender requirements with their sales hat on. Courts read them differently and look strictly at the wording. Small details can determine whether a bid is accepted or rejected.”
Below are five common mistakes they see and how you can avoid them.
1. Not asking clarification questions early enough
Some suppliers assume they can challenge problematic requirements after the contract has been awarded. In reality, that can be difficult.
If a requirement appears unclear or unusually strict, suppliers are often expected to raise the issue during the clarification period before submitting their bid.
How to avoid this mistake
- Review the tender documents early in the process
- Identify requirements that are unclear or open to interpretation
- Submit clarification questions through the procurement platform before the deadline
Key takeaway
The clarification phase is an opportunity to reduce risk. Treat it as an active part of your bidding strategy.
2. Assuming references will always be available
Reference checks can play an important role in the evaluation of bids. A common issue arises when contracting authorities attempt to contact references and do not receive a response.
Even if the reference has previously agreed to participate, the requirement may still be considered unfulfilled if the authority cannot reach them.
How to avoid this mistake
- Inform references about the procurement before submitting your bid
- Confirm that they will be available during the evaluation period
- Provide accurate contact details and make sure they are up to date
Key takeaway
Do not assume references will automatically respond. Preparation can prevent unnecessary problems during evaluation.
3. Reading requirements with “sales eyes”
Suppliers often interpret requirements based on what seems logical from a business perspective. However, procurement requirements are usually interpreted strictly according to their wording.
For example, if a requirement states that compliance must be verified, it may not be enough to simply state that the requirement is fulfilled. Documentation or supporting evidence may be required.
How to avoid this mistake
- Read each requirement carefully and literally
- Identify where documentation or proof is required
- Make sure your bid clearly demonstrates compliance
Key takeaway
In public procurement, wording matters. Clear documentation can be just as important as the offer itself.
4. Overpromising in the bid, especially when using AI
AI tools are becoming more common in bid preparation. They can help structure answers and draft text quickly. However, they can also introduce risk.
AI-generated descriptions may present processes or capabilities that do not fully reflect how your organisation actually works. Since commitments made in a bid may later become contractual obligations, this can create legal and operational problems.
How to avoid this mistake
- Use AI as a support tool rather than the final author
- Review responses internally with subject-matter experts
- Ensure all commitments in the bid reflect real capabilities
Key takeaway
Your bid is not just marketing. In many cases it becomes part of the contract.
5. Believing tender documents cannot be influenced
Many suppliers assume that procurement documents are fixed once the tender has been published. In practice, contracting authorities can often clarify or adjust certain elements during the tender period.
Suppliers who review the documents early and raise relevant questions may reduce risk and gain a better understanding of how requirements will be interpreted.
How to avoid this mistake
- Analyse tender documents as soon as they are published
- Identify requirements that appear unclear or restrictive
- Raise clarification questions during the tender period
Key takeaway
Tender documents are not always final. Active suppliers use the clarification phase to improve their understanding of the process.
Before submitting your bid
Before submitting your bid, take a moment to confirm the following:
✔ All requirements have been clearly answered
✔ Supporting documentation is attached where required
✔ References are informed and available
✔ The commitments described in the bid reflect actual capabilities
In public procurement, attention to detail can make the difference between acceptance and rejection.
