Confirm you are eligible and it is worth bidding
Check licences, insurances, certifications, and any conformance requirements before you commit. A quick bid or no-bid decision saves days of wasted effort on a tender you cannot win.
Answer every criterion with evidence
Respond to each evaluation criterion directly and back your claims with concrete examples, referees, and past performance. Address the buyer’s stated need, not a generic capability statement.
