Deciding whether to bid · 2 min read

Bid or no bid: a checklist for firms of five to fifty people

Every tender you write costs days you could have spent on paying work. A straightforward way to decide which ones deserve them.

Published 13 September 2026

A small firm cannot bid for everything, and should not try. A serious tender response takes days of senior time. Spread that across contracts you were never likely to win and you lose twice: the time, and the bid you rushed because of it.

Deciding not to bid is a skill. Here is a checklist that makes the decision quickly and consistently.

Can we win it?

  • Do we pass the gates? Turnover, insurance, accreditations, years trading. If the minimum turnover is several times yours, stop. Government guidance has long been that a turnover requirement should not normally exceed twice the contract value, so a test far beyond that is worth querying, but not worth betting a bid on.
  • Is there a lot or a size we can deliver? Look at the value per lot, not the headline figure.
  • Do we have the evidence? Recent, comparable work with named clients and outcomes you can describe. If the questions ask for three examples and you have one, the score will show it.
  • Who holds it now? A long-standing incumbent that has delivered well is hard to displace. A specification that reads like a description of one company's service is a warning sign.
  • Does the scoring suit us? Heavy quality and social value weightings favour a firm that can write well about real, local delivery. Price-dominated scoring favours scale.

Can we deliver it?

  • Capacity. If we won, could we mobilise by the start date without letting existing clients down?
  • Geography. Can we service every site, or is this realistically regional work in a national wrapper?
  • People. Does TUPE apply, and do we understand what taking on the current workforce would mean?
  • Cash flow. Public bodies must pay undisputed invoices within 30 days under the Act, but mobilisation costs come first.

Do we want it?

  • Margin. At a price that could win, is there a profit?
  • Strategy. Does it open a buyer, a sector or a region we want, even if the contract itself is marginal?
  • Risk. Penalties, unlimited liabilities, or KPIs we cannot control.

A simple scoring rule. Score each question 0 (no), 1 (partly) or 2 (yes). Any 0 on "do we pass the gates" or "can we mobilise" is an automatic no. Otherwise, set a threshold that fits your win rate, and write down the score for every decision. Within a year you will know which kinds of tender are worth your time.

How Bidwire helps with the first pass

Each notice in Bidwire carries a small-firm flag and, where one applies, a plain list of reasons it might not suit a small firm: a very large contract, a stated turnover requirement over £5 million, or a need to cover the whole country. Those are worked out from the notice's own figures, not guessed, so you can see exactly why.

Where a notice lets us, it also names a possible incumbent drawn from the buyer's previous awards. Treat that as a lead to check, not a fact.
