Why this decision has to happen before drafting starts
Bid teams that skip a real bid/no-bid decision tend to default to "yes" — the tender arrived, someone's already read the first few pages, momentum takes over. The cost shows up later: a team three weeks into a compliant, well-written response for a tender they were never realistically going to win, that could have been three weeks on a tender they were.
Six questions worth answering honestly
1. Can you actually be compliant?
Not "mostly compliant" — genuinely able to meet every mandatory condition and gate. If a mandatory certification, financial threshold or track-record requirement is out of reach, no amount of writing quality recovers it.
2. Is the relationship or track record there?
Public sector procurement scores relevant experience and referee performance heavily. An honest read of your last three comparable projects — including the ones that didn't go perfectly — is worth more than optimism here.
3. Is the commercial model workable?
A tender with a pricing model, risk allocation or contract form your organisation can't responsibly accept is a no-bid regardless of how good the fit looks on paper — chasing revenue on unworkable terms is a slower way to lose money than not bidding at all.
4. Do you have the capacity, right now, to do this properly?
Not "can we free someone up" — do the actual people who'd need to write, review and price this have the calendar space to do it to a standard that wins. A resourced, honest no-bid beats a stretched, mediocre bid.
5. What's the real win probability, not the hopeful one?
Number of realistic competitors, incumbent advantage, how well the requirements map to what you've actually delivered before — not how well they map to what your marketing says you do.
6. What does winning actually cost you elsewhere?
Capacity committed to this tender is capacity not available for the next one. Sometimes the right call is "yes, but only if we also decline the next two."
A simple scoring approach
Score each of the six questions 1–5, weight compliance and commercial workability higher (they're pass/fail in practice more often than they're a spectrum), and set an explicit threshold below which the answer is no by default — not "let's discuss." The value of a scoring approach isn't the arithmetic, it's that it forces the honest answer onto paper before enthusiasm for the opportunity talks the team out of it.
Make the decision reversible, once
A structured requirement/risk read of the actual tender pack — rather than a skim of the covering letter — is the single best input into questions 1 and 3 above. Teams that make the bid/no-bid call before reading the full pack in structured detail are, in practice, making it on the covering letter's optimism rather than the tender's actual conditions.
