Top 10 Tender Writing Mistakes (and How to Fix Them)

25th March 2025

Writing a successful tender is a vital skill for any organisation aiming to win contracts and grow. Yet, many businesses fall short due to avoidable errors in their submissions. From formatting issues to failing to understand the buyer, these mistakes can significantly reduce your chances of success.

In this guide, we highlight the ten most common tender writing mistakes, explain how to correct them, and offer practical tips to strengthen your bids.

1. Failing to Follow Instructions Precisely

Tender documents usually include specific requirements around formatting, word count, structure, and deadlines. Not following these can result in automatic disqualification.

Fix: Read the tender documents carefully. Create a checklist of requirements and review your response against it before submission.

Discover how our bid writing service ensures compliance at every stage of the process.

2. Submitting Generic Content

Using recycled content that doesn’t address the specific requirements of the opportunity signals a lack of effort and understanding.

Fix: Tailor every response. Align your proposal with the buyer’s objectives, and demonstrate why your organisation is uniquely placed to deliver.

Our bid strategy support helps you craft bespoke responses that resonate with evaluators.

3. Ignoring the Presentation

Even strong content can be overlooked if the document is difficult to read. Poor layout, inconsistent fonts, or lack of structure makes a bad impression.

Fix: Use clear headings, bullet points, and consistent formatting. Visual elements like tables and graphs can help explain complex ideas.

Explore our design and layout support to enhance your submission’s visual appeal.

4. Burying Key Information

Important messages hidden in long paragraphs or back pages may be missed entirely by the evaluators.

Fix: Place your unique selling points early, ideally in the executive summary. Make sure your key strengths are front and centre.

5. Overloading with Irrelevant Information

Adding too much content can dilute your key messages and frustrate the reader.

Fix: Stick to the buyer’s questions and criteria. Be concise and focus on what they value most.

6. Not Starting with a Clear Strategy

Jumping straight into writing without a plan often leads to inconsistencies and missed opportunities.

Fix: Define your strategy first. Identify what the client is looking for and how you will position your strengths to meet those needs.

7. Lack of Proofreading and Editing

Spelling mistakes, grammatical errors, and unclear writing reduce professionalism and credibility.

Fix: Always proofread. Ideally, have a second pair of eyes review your submission. Professional editing support can make a significant difference.

We offer expert review and quality assurance services to elevate your final draft.

8. Failing to Answer the Question

It’s surprisingly common to go off-topic or provide incomplete responses.

Fix: Break down each question and answer it in full. Use subheadings if needed to mirror the structure of the question.

9. Not Understanding the Client’s Business

Without insight into the buyer’s organisation and challenges, your bid will lack relevance.

Fix: Research the client thoroughly. Reflect their language and priorities in your response. Demonstrate a clear understanding of their goals.

10. Non-Compliance with Tender Specifications

Misreading requirements or missing documentation can lead to technical non-compliance.

Fix: Use a compliance matrix or checklist. If anything is unclear, seek clarification before the submission deadline.

Conclusion

Tendering is a competitive and detailed process, but avoiding these common mistakes can drastically improve your win rate. With strategic planning, tailored content, and rigorous quality control, your tenders will better align with what buyers expect.
