Writing tenders is high-stakes work where a single mistake can cost you a valuable contract. After analyzing thousands of failed bids, we've identified the top 5 mistakes that repeatedly cause businesses to lose tenders – and more importantly, how to fix them.

The 5 Most Costly Tender Writing Mistakes

1. Failing to Follow Instructions (Causes 32% of Tender Failures)

The Mistake: Missing deadlines, incorrect formatting, exceeded word counts, or forgotten signatures lead to automatic disqualification. Real Example: A construction firm lost a £2.3M contract because they submitted their tender 3 minutes late due to upload issues. The Fix:
  • Create a compliance checklist for every tender
  • Set internal deadlines 24 hours before actual deadlines
  • Use AI-powered compliance checking tools
How AI Helps: Modern AI platforms like MyTender automatically scan tender requirements and create compliance checklists, flagging any missing elements before submission.

2. Submitting Generic, Copy-Paste Content (Causes 28% of Tender Failures)

The Mistake: Recycling content from previous bids without customization. Evaluators easily spot generic "waffle" that doesn't address specific requirements. Warning Signs:
  • Using phrases like "we always" or "our standard approach"
  • Content that could apply to any tender
  • Missing specific references to the buyer's needs
The Fix:
  • Analyze the buyer's specific pain points
  • Customize every response to their requirements
  • Use concrete examples relevant to their industry
How AI Helps: AI analyzes the tender requirements and generates customized content specific to each opportunity, ensuring responses directly address the buyer's needs.

3. Making Unsubstantiated Claims (Causes 21% of Tender Failures)

The Mistake: Statements like "we are the leading provider" or "best in class" without evidence. Common Unsubstantiated Claims to Avoid:
  • "Industry leader" (without rankings/awards)
  • "Unmatched expertise" (without qualifications)
  • "Exceptional service" (without testimonials)
  • "Proven track record" (without case studies)
The Fix:
  • Back every claim with data
  • Include specific metrics and KPIs
  • Reference awards, certifications, and client testimonials
  • Provide relevant case studies
How AI Helps: AI-powered systems maintain a searchable database of your evidence, automatically suggesting relevant proof points for each claim.

4. Poor Presentation and Clarity (Causes 12% of Tender Failures)

The Mistake: Dense paragraphs, typos, inconsistent formatting, and buried key points frustrate evaluators. Presentation Checklist:
  • ✓ Clear headings and subheadings
  • ✓ Bullet points for key information
  • ✓ Consistent formatting throughout
  • ✓ No spelling or grammar errors
  • ✓ Key points highlighted or bolded
  • ✓ White space for readability
The Fix:
  • Use professional templates
  • Implement peer review processes
  • Allow time for proofreading
  • Follow the 3-second rule: key points visible in 3 seconds
How AI Helps: AI tools provide consistent formatting, automated proofreading, and ensure key points are prominently displayed.

5. Failing to Answer the Actual Question (Causes 7% of Tender Failures)

The Mistake: Going off-topic or providing incomplete responses, often when recycling old content. Example Questions Often Misunderstood:
  • "How will you..." (requires specific methodology, not capabilities)
  • "What evidence..." (requires proof, not promises)
  • "Demonstrate your..." (requires examples, not descriptions)
The Fix:
  • Read each question three times
  • Underline key words in the question
  • Structure responses using STAR method (Situation, Task, Action, Result)
  • Have someone else verify you've answered the question
How AI Helps: AI analyzes questions to ensure responses stay on-topic and fully address all requirements.

The Hidden Cost of Manual Tender Writing

These mistakes aren't random – they're symptoms of a broken process. When tender writers spend 80% of their time on administrative tasks (searching for information, copying old content, formatting), they have insufficient time for strategic thinking and quality control.

Time Breakdown of Traditional Tender Writing:
  • 40% - Searching for information and old content
  • 25% - Copying and pasting from previous bids
  • 15% - Basic formatting and administration
  • Only 20% - Strategic writing and customization
