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

Want to learn how to write a tender that wins contracts? A strong tender response clearly explains how you will deliver the contract, demonstrates your experience and shows the value you offer.

However, successful tenders do not start with writing alone. They require planning, structure and a clear understanding of what evaluators are looking for. This guide walks you through the full bid writing process, helping you move from opportunity identification through to submission and improvement.

If you are new to bidding, start with our complete guide to how to write a bid to understand how each stage fits together.

What does it mean to write a tender?

Writing a tender is the process of responding to procurement documents and submitting a formal proposal to deliver goods or services. It involves showing that your organisation can meet the buyer’s requirements, manage risk, deliver quality and provide value for money.

In practical terms, writing a tender means turning your capability into a structured submission that answers the buyer’s questions clearly and gives evaluators confidence in your delivery.

A typical tender submission includes:

• Quality responses to method statements or tender questions
• Pricing schedules or commercial submissions
• Case studies and evidence of similar delivery
• Policies, procedures and accreditations
• Company information and declarations
• CVs, organograms or staffing information where required

To understand the broader process, you can also read about what tendering is in business and the tendering process.

Why learning how to write a tender matters

Many suppliers can deliver the contract, but far fewer can explain that clearly in a written submission. That is why tender writing matters. Buyers do not assess you based on assumptions. They assess what you submit.

A weak response can lose marks even when your business is fully capable of delivering the work. A strong response makes your offer easy to understand, easy to score and easy to trust.

Learning how to write a tender properly helps you:

• Choose better opportunities
• Improve compliance
• Present stronger evidence
• Align with evaluation criteria
• Reduce avoidable mistakes
• Improve your tender success rate over time

The tender writing process

Winning bids follow a structured process. Each stage builds towards a high-quality, compliant and competitive submission.

1. Decide whether to bid

Before writing anything, decide whether the opportunity is right for your business. This is known as a bid/no-bid decision, and it is one of the biggest factors in improving your success rate.

Many organisations waste time bidding for contracts they are unlikely to win. A strong bid strategy focuses on opportunities where you have a genuine chance of success and where the contract fits your commercial goals.

Ask yourself:

• Do you meet the financial and technical requirements?
• Do you have relevant experience and case studies?
• Can you deliver the contract within the required timeframe?
• Do you have the right people, systems and capacity?
• Is the opportunity commercially viable?
• Can you offer something credible and competitive?

If the answer to several of these questions is no, it is often better to step back and focus on stronger opportunities.

2. Review the tender documents

Once you decide to bid, review the full tender pack carefully. Many bids fail not because of poor writing, but because suppliers misunderstand the requirement or miss a key instruction.

You should review:

• Specification and scope of work
• Evaluation criteria and scoring methodology
• Submission deadlines and clarification deadlines
• Formatting rules, word counts and page limits
• Mandatory documents and compliance requirements
• Pricing schedules and commercial assumptions

This stage is about building a clear picture of what the buyer expects. For a deeper breakdown, see our guide to tender documents explained.

3. Understand how the tender will be scored

Before you start drafting, check how the buyer will assess your submission. Most tenders are scored using weighted criteria, usually combining quality and price. Some opportunities also include presentations, interviews or social value weightings.

When you understand the scoring model, you can focus effort where it matters most. Questions with higher weightings need stronger evidence, clearer structure and more detail.

Learn more in our guide to how bids are scored and scoring systems in tendering.

4. Plan your response

Planning your response before writing improves both quality and efficiency. A structured approach helps you cover every requirement and manage internal input more effectively.

This usually involves:

• Breaking down each question into key requirements
• Identifying what a high-scoring answer needs to include
• Assigning responsibilities across your team
• Gathering relevant evidence and supporting documents
• Creating a response plan or storyboard
• Setting internal deadlines for drafts and reviews

Following a clear bid management process helps you stay organised and maintain quality across the submission.

5. Write clear, structured answers

Writing is where many bids succeed or fail. Evaluators review multiple submissions, often under time pressure, so clarity and structure are essential.

High-scoring responses:

• Answer the question directly
• Follow a logical structure
• Use clear headings and formatting
• Focus on relevant detail
• Explain delivery rather than making vague claims
• Make evidence easy to find

A useful structure is:

• Introduction: Answer the question directly
• Approach: Explain how you will deliver
• Evidence: Provide relevant examples
• Outcome: Show results, benefits and added value

This structure helps evaluators follow your response and award marks more easily. For more detail, see our guide to answering tender questions and improving quality tender responses.

6. Focus on what the buyer wants to see

One of the most common mistakes in tender writing is answering with what you want to say instead of what the buyer has asked. Strong tender writing stays tightly aligned to the specification, scoring guidance and contract outcomes.

When writing each answer, ask:

• Have we answered the question directly?
• Have we explained how we will deliver this requirement?
• Have we given evidence that proves we can do it?
• Have we shown the benefit to the buyer?

This keeps your response focused and reduces generic content that loses marks.

7. Use evidence and case studies

Strong tenders rely on evidence rather than claims. Buyers want proof that you have delivered similar contracts successfully and that your proposed approach is credible.

Effective evidence includes:

• Relevant case studies
• Measured outcomes or KPIs
• Client feedback or testimonials
• Examples of mobilisation and delivery
• Accreditations, systems and audit results where relevant

Your examples should match the scope, scale and complexity of the contract wherever possible. Learn how to present them effectively in our case studies guide.

8. Develop strong method statements

Method statements explain how you will deliver the contract. They form the core of many quality responses and should be clear, structured and aligned with the specification.

A strong method statement:

• Explains your delivery approach clearly
• Shows responsibilities and process ownership
• Addresses risks and challenges
• Demonstrates compliance with the requirement
• Explains how you will achieve outcomes
• Shows review, reporting and continuous improvement

For more guidance, read our method statement guide.

9. Price your bid effectively

Pricing is a critical part of your submission. Most tenders are evaluated on both quality and price, so you need to balance competitiveness with value.

Your pricing should:

• Be accurate and realistic
• Reflect your delivery approach
• Cover the full cost of delivery
• Demonstrate value for money
• Remain commercially sustainable

Poor pricing can undermine even a strong technical response. Learn more in our tender pricing strategy guide.

10. Manage the timeline

Effective bid management helps you meet deadlines and maintain quality. Poor time management leads to rushed answers, missing attachments and avoidable mistakes.

Key considerations include:

• Setting internal deadlines before the submission date
• Allowing time for reviews and revisions
• Managing contributions from multiple stakeholders
• Leaving enough time for portal upload and final checks

See our tender timeline guide for a structured approach.

11. Review, refine and submit

Before submission, review your tender to ensure it meets all requirements. This stage is about more than proofreading. You should test whether the response is complete, relevant and easy to evaluate.

Use a tender submission checklist to confirm:

• All questions are fully answered
• Instructions have been followed
• Word counts and formatting are correct
• Attachments are complete and up to date
• No errors or inconsistencies remain

Submit your tender early to reduce the risk of technical issues and portal delays.

What makes a winning tender?

Winning tenders go beyond compliance. Many submissions meet the minimum requirements, but only a few stand out to evaluators.

High-scoring tenders:

• Make it easy for evaluators to understand the response
• Provide strong, relevant evidence
• Align closely with evaluation criteria
• Demonstrate added value
• Reduce perceived delivery risk
• Show a clear and credible implementation approach

Procurement teams are often reviewing multiple similar submissions. If your response feels difficult to read, generic or poorly organised, it is less likely to score highly. Learn more in our guide to writing winning bids.

How to structure tender responses

Structure plays a major role in how your bid is evaluated. A well-structured answer is easier to read, easier to score and more likely to achieve higher marks.

A simple and effective structure includes:

• Introduction: Answer the question clearly and directly
• Approach: Explain your delivery method
• Evidence: Support your claims with examples
• Outcome: Demonstrate results and benefits

Poorly structured responses often lose marks, even when the underlying capability is strong. Clarity and organisation make a significant difference to how evaluators perceive your submission.

Additional tender requirements

In addition to quality responses, most tenders require supporting documentation. These documents help buyers assess compliance, capability and organisational credibility.

• Policies and procedures
• Accreditations and certifications
• Team structures or CVs
• Financial information
• Declarations and compliance statements
• Insurances and legal information

Many opportunities also include a pre-qualification stage such as a Selection Questionnaire (SQ). If you do not manage these supporting requirements well, you can lose the opportunity before quality scoring even begins.

Common mistakes when writing a tender

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

• Not answering the question fully
• Using generic or recycled content
• Ignoring instructions or formatting requirements
• Providing weak or irrelevant evidence
• Failing to align with the evaluation criteria
• Leaving reviews and submission too late
• Submitting without a final compliance check

Read more in our guide to common bid writing mistakes.

How do buyers score tender responses?

Buyers assess tenders based on criteria such as quality, price, technical capability, contract management, mobilisation and delivery approach. Some procurements also assess social value, innovation or risk management.

Understanding how scoring works helps you focus your responses and improve your overall result. Instead of treating every question equally, you can prioritise the areas with the highest scoring impact.

Read more in our guides to how bids are scored and scoring systems in tendering.

Improving your tender success rate

Improving your success rate requires a structured and consistent approach. Winning more contracts is rarely about writing one better answer in isolation. It comes from improving your whole bidding process over time.

• Build and maintain a bid library
• Learn from feedback and previous submissions
• Focus on relevant opportunities
• Strengthen your evidence base and case studies
• Review what buyers consistently score highly
• Understand procurement routes such as framework tenders and DPS vs frameworks

Continuous improvement is key to long-term success in bidding.
