How to Write a Tender: Step-by-Step Guide for Suppliers

Writing a tender means preparing a structured response that shows a buyer how you will deliver their contract, why your business is suitable and what value you offer. A strong tender response is clear, evidence-led and tailored to the buyer’s requirements.

However, successful tenders do not start with writing alone. First, you need to decide whether the opportunity is right for your business, review the documents carefully and understand exactly what the buyer is asking for.

What does it mean to write a tender?

Writing a tender is the process of responding to a buyer’s procurement documents and submitting a formal proposal for a contract. In practice, this usually involves answering quality questions, completing pricing documents and providing supporting evidence such as case studies, policies and accreditations.

If you are new to the process, you may also find it useful to read our guides on what tendering is in business, the tendering process and Invitation to Tender (ITT).

How to write a tender response

1. Decide whether to bid

Before you start writing, make sure the opportunity is right for your business. For example, check whether you meet the financial requirements, have relevant experience and can deliver the contract successfully.

  • Do you meet the eligibility criteria?
  • Do you have relevant case studies?
  • Do you have the required accreditations or policies?
  • Do you have the capacity to deliver the contract?

If the answer is no to several of these questions, it may be better to step back and make a clear bid or no-bid decision.

2. Review the tender documents carefully

Do not jump straight into drafting. Instead, read the full tender pack first so you understand the buyer’s requirements, the submission rules and the evaluation criteria.

At this stage, make a note of:

  • Submission deadline
  • Clarification deadline
  • Word counts or page limits
  • Mandatory attachments
  • Scoring criteria
  • Formatting instructions

Missing small details at this stage can damage an otherwise strong submission.

3. Break down each question

Tender questions often contain multiple parts. Therefore, one of the best ways to improve your score is to break each question down before you start writing.

For example, if a buyer asks about risk management, they may actually want you to cover identification, monitoring, mitigation, responsibilities and examples. If you miss one of these points, you may lose marks even if the rest of your answer is strong.

Using short subheadings can help you structure your response clearly and show the evaluator that you have addressed every part of the question.

4. Write clearly and directly

Buyers often review large numbers of submissions. As a result, clear and well-structured answers are easier to score than long, repetitive responses.

When writing your tender:

  • Answer the question directly
  • Use clear headings and subheadings
  • Keep your writing concise and relevant
  • Avoid generic claims that add no value
  • Use evidence to support your points

Strong responses usually follow a simple structure: make your point, provide evidence and explain how you will deliver the requirement.

5. Use relevant evidence and case studies

Good tender writing is not just about making claims. You also need to prove that your business can deliver. Therefore, use relevant case studies, examples and results wherever possible.

Strong evidence may include:

  • Similar contracts delivered
  • Performance outcomes or KPIs
  • Mobilisation experience
  • Lessons learned and improvements made
  • Customer testimonials or contract extensions

Keep your examples relevant to the scope, scale and complexity of the contract you are bidding for.

6. Tailor your answers to the buyer

One of the most common mistakes in tender writing is using generic content. Buyers want to see that you understand their requirements, challenges and priorities.

Therefore, tailor your answers to the contract at hand. Reflect the wording of the specification where appropriate, address the buyer’s objectives and explain how your approach meets their needs.

7. Review and proofread

Before submission, review each answer carefully. Check that it answers the question fully, stays within any word count and aligns with the buyer’s scoring criteria.

Then proofread the full document for spelling, grammar, formatting and consistency. In addition, it helps to ask a colleague to review the draft, as a fresh pair of eyes can often spot mistakes or gaps.

8. Submit in good time

Do not leave submission until the last minute. Procurement portals can be slow, attachments can fail to upload and buyers rarely accept late bids.

Submitting early gives you time to resolve technical issues and reduces the risk of avoidable mistakes.

What should a tender response include?

Although every tender is different, most responses include a combination of the following:

  • Quality responses
  • Pricing documents
  • Case studies
  • Policies and procedures
  • Accreditations and certifications
  • CVs or team structure
  • Declarations and mandatory documents

Some tenders may also include a pre-qualification stage such as a PQQ or Selection Questionnaire before the full response stage.

Common mistakes when writing a tender

Many suppliers lose marks because of avoidable mistakes. The most common include:

  • Not answering the question properly
  • Using generic or recycled content
  • Ignoring the buyer’s instructions
  • Providing weak evidence
  • Writing too much filler content
  • Failing to proofread
  • Submitting too late

These issues can reduce your score even when your business is capable of delivering the contract.

How do buyers score tender responses?

Buyers usually score responses against published criteria such as quality, price, technical ability and social value. Therefore, the strongest tender responses do not simply describe your business. Instead, they align closely with the evaluation criteria and demonstrate clear value.
