How to Prepare a Tender Document That Wins

Learn how to prepare a tender document that wins contracts. Step-by-step process, proven guidelines, expert tips, and real case studies for success.

Why Tender Document Preparation Matters

In competitive bidding, the quality of your tender documents can decide whether you win or lose a contract. A clear, complete, and persuasive submission not only meets the evaluation criteria, but also shows the client you understand their project requirements and can deliver.

Whether in the public sector or private markets, the tendering process is designed to ensure fairness and value for money. But to succeed, your bid must stand out — and that starts with strong preparation.

Understanding the Tendering Process

Before diving into the process of preparing tender documents, it’s worth revisiting what bid management is:

  1. Tender opportunity identified – This may be a public request for proposal (RFP), an invitation to tender (ITT), or a selective bid for prequalified suppliers.
  2. Bidding documents issued – The client releases all relevant details, including scope of work, submission instructions, and evaluation criteria.
  3. Bid preparation – You gather information, develop your solution, calculate pricing, and prepare your tender response.
  4. Submission – Deliver the completed tender documents by the deadline, following all requirements exactly to ensure compliance.
  5. Evaluation and award – The client reviews submissions, scores them against the criteria, and awards the contract to the winning bidder.

How to Prepare a Tender Document (Step-by-Step)

Here’s a clear, actionable tender document preparation process that works across industries and contract types:

1. Review the Tender Documents Thoroughly

Start by reading the client’s instructions from start to finish. Identify:

  • Deadlines for submission and clarification questions.
  • Required format, structure, and number of copies.
  • Mandatory forms, attachments, and certificates.
  • Sections to be priced and sections to be unpriced.

Tip: Missing a requirement can result in disqualification, even if your offer is competitive.

2. Understand the Scope of Work and Requirements

The scope of work is the heart of any tender. Clarify:

  • Deliverables, timelines, and performance standards.
  • Any specific technical or quality requirements.
  • Resource and staffing expectations.
  • Contract length, renewal options, and long-term commitments.

Engage subject matter experts early to confirm you can meet — or exceed — these project requirements.

3. Build Your Bid Team and Assign Roles

Good bid management means bringing the right people together:

  • Technical specialists to address the solution.
  • Commercial staff for pricing.
  • Legal to review contract terms.
  • Quality and safety teams for compliance sections.

Assign responsibilities for each section of the bid proposals and set internal deadlines.

4. Develop a Clear Strategy

Ask yourself:

  • What will differentiate our tender response from others?
  • Are we competing on price, quality, innovation, or service?
  • What risks might the client see, and how can we address them?

Use this proposal strategy to guide your writing, ensuring your message is consistent throughout the submission.

5. Create the Tender Document Structure

Follow the tender document preparation guidelines exactly, while making your content easy to navigate. Typical structure includes:

  • Executive Summary – Summarize why you’re the best choice.
  • Company Profile – Experience, track record, and capability.
  • Technical Proposal – How you’ll deliver the scope of work.
  • Commercial Proposal – Detailed pricing and payment terms.
  • Compliance Checklist – Evidence you meet all requirements.
  • Supporting Documents – CVs, case studies, certificates.

6. Write with Clarity and Impact

When preparing tenders, keep your writing clear, concise, and relevant:

  • Mirror the client’s language from the bidding documents.
  • Answer each requirement in full.
  • Use bullet points, tables, and visuals for clarity.
  • Avoid jargon unless it’s standard in the industry.

7. Review and Ensure Compliance

Before submission:

  • Cross-check against the tender instructions.
  • Verify all mandatory forms are signed and included.
  • Ensure pricing matches your cost model.
  • Review formatting, branding, and layout.

Tip: A compliant bid may not guarantee a win, but a non-compliant bid is usually rejected without review.

Proven Guidelines for Successful Tender Responses

  • Start early – Rushed bids miss details and weaken your position.
  • Centralize content – Keep approved material in a shared library.
  • Communicate internally – Regular updates avoid last-minute surprises.
  • Think long-term – Position yourself for future work, not just this tender.
  • Learn from feedback – Use client debriefs to improve your process.

Real-World Example: Tender Process Transformation

DeepOcean, a global ocean services provider, once relied on manual formatting and fragmented workflows for their tender document preparation process. Their team faced:

  • Hours spent fixing formatting before submission.
  • Searching for standard content in multiple locations.
  • Manual tracking of tasks and deadlines.

Switching to tender management software changed their process of preparing tender documents:

  • Time saved and reduced stress before deadlines.
  • Better access to up-to-date content.
  • Improved team coordination and progress tracking.
  • Professional, consistent formatting every time.

“Now I don’t have to spend the last two days working past midnight to get the document ready. The software has already done that work for us.” – Ragnhild Brekke-Brandtzæg, Tender Manager, DeepOcean.
