Common Tender Submission Mistakes and How to Avoid Them
By Denise Daví, founder of DAVIA · Published · Updated
Short answer
The most avoidable mistakes are organisational: missing the deadline, leaving out a required document, ignoring word limits, and not answering the question exactly as the evaluation criteria describe. A checklist, a timeline and a final compliance review prevent most of them.
Leaving submission to the last hour
Portals can be slow and uploads can fail. Buyers normally reject late submissions, so set an internal deadline well before the official one.
Missing mandatory documents
Requirements are often spread across several files. Build one checklist of every form, declaration, certificate and attachment the tender asks for, and tick each off before submitting.
Not answering the actual question
Evaluators score against published criteria. Re-read each question and its scoring guidance, answer every part, and use the buyer's terminology.
Ignoring word and format limits
Content beyond a word limit may not be read. Follow the instructions on length, format and file naming exactly.
Generic, unevidenced claims
Statements such as 'we deliver excellent service' score poorly without evidence. Use specific, verifiable examples from your own work.
Missing clarification deadlines
If something is unclear, ask the buyer before the clarification deadline. Answers are usually shared with all bidders and can change how you respond.
