When to walk away from a bid you have already started

Most bid/no-bid advice treats the decision as a single moment: the solicitation arrives, the team meets, someone says yes. In practice the deal keeps changing after that meeting. The final RFP differs from the draft. An amendment moves the deadline or adds a requirement. The key person you named takes another job. Halfway through the writing, the question comes back: should we still be doing this?

The short answer is that a bid decision is only as good as the facts it was made on, so it should be reopened whenever those facts change materially, and the time already spent should play no part in the answer. This article covers how to tell when a change is material, how to run the second decision quickly, and what walking away actually involves.

The deal you said yes to is not the deal in front of you

Federal solicitations change in writing, and the rules require it. Under FAR 15.206, when the government changes its requirements or terms and conditions, before or after proposals arrive, the contracting officer must amend the solicitation. Amendments issued before the proposal deadline go to everyone who received the solicitation, so every bidder sees the same change at the same time.

Each amendment is therefore a small new solicitation. Most are routine: a corrected page number, an answered question, a few extra days. Some change what you agreed to bid on. The common ones that should trigger a second look:

• Scope added or reshaped. A new task area, a different place of performance, or a labor category you do not staff.
• Evaluation criteria reweighted. Price moves from secondary to equal weight, or a technical factor you were strongest on shrinks.
• New eligibility or compliance gates. A certification, a facility clearance, a specific contract vehicle, or a set-aside change.
• Schedule compressed. A shorter response window, or an earlier start of performance that your transition plan cannot meet.
• Questions answered against you. The government's answer to an industry question closes the reading of the requirement your approach depended on.

FAR 15.206 also contains a rule at the other extreme: if an amendment after proposals arrive is so substantial that other companies likely would have bid had they known, the contracting officer must cancel and issue a new solicitation. Most material changes fall well short of that line, and they are the bidder's to judge.

Changes on your side count too

Not every reason to reconsider comes from the buyer. Internal changes are just as material and are noticed later, because no one issues an amendment for them:

• The key person or program manager you planned to propose is no longer available.
• A teaming partner withdraws, or wants a larger share than the plan assumed.
• Another pursuit with a better fit arrives with an overlapping deadline.
• Delivery work on an existing contract needs the same people this month.

Each of these changes the capacity and past-performance assumptions behind the original yes. The economics of bidding depend on spending proposal hours where the odds are best, and a pursuit whose odds dropped after the yes is no longer that place.

Sunk cost is the wrong input

The most common reason teams finish a bid they would not start today is the hours already spent. Those hours are gone whatever you decide next. The only question that matters is whether the remaining hours are better spent on this bid than on the alternatives.

Write the second decision as if you were seeing the pursuit for the first time, with today's facts:

1. What changed? Name the amendment, answer or internal change, in one sentence each.
2. Which original reason does it touch? Every yes rested on a few reasons: a known buyer, close past performance, available people, a competitive price. Mark which ones still hold.
3. What does finishing cost? Count the remaining hours by person, not the hours already logged.
4. What does finishing displace? Name the other pursuit or delivery work that gives up those hours.
5. Who decides? The same person who made the first call, or whoever your process says may overturn it.

If two of the original reasons no longer hold, the answer is usually to stop. If one weakened but the rest hold, adjust the plan instead: drop an optional volume, narrow the approach, or bring in a partner for the new scope.

Walking away is allowed, and it can be done cleanly

Before the deadline, not submitting is the whole of it. Nothing obliges a company that downloaded a solicitation to respond. A short, courteous note to the contracting officer that you will not be submitting is a professional habit, not a requirement, and it can carry useful information: if a requirement you raised in questions is the reason, saying so helps the buyer see the market's view.

After the deadline, a proposal can still be withdrawn. The standard instructions to offerors in FAR 52.215-1 provide that proposals may be withdrawn by written notice received at any time before award. That is the exception, for when something has changed so much that the company cannot perform what it offered, and it is a step to take with your contracts lead and, where needed, counsel.

The federal acquisition rules are being rewritten. Under the Revolutionary FAR Overhaul, the FAR Council has posted model deviation text for Part 15, and agencies are adopting it through class deviations, so section numbers and wording can differ from agency to agency. Read the instructions in the solicitation you are working on, which govern that procurement.

Make the second decision as visible as the first

Teams record the first yes in a capture meeting and almost never record the second look. That loses the most useful learning in the pipeline. A record of "we stopped after amendment 3 added a facility clearance we could not get in time" tells the next pursuit with that buyer what to check on day one.

Three habits keep it visible:

• Treat each material amendment as a checkpoint, not an editing task. Someone reads it against the decision before anyone edits the draft.
• Record the reopened decision with its reason, beside the original. Both stay on file; the new one does not erase the old.
• Count stopped pursuits as decisions, not losses. A stop recorded early is hours returned to better work. For a small team, as the small-business article on declining bids argues, those hours are the scarcest thing it has.

The short version

A bid decision is made on the facts of the day, and amendments, answered questions and internal changes all move those facts. Reopen the decision when they do, judge it on the hours still to spend rather than the hours already spent, and record the second call as carefully as the first. Walking away early, or even withdrawing before award when the rules allow, is often the strongest bid strategy move a team makes.
