In the room, the customer tells you a competitor has committed to something you cannot match. How do you respond?

The claim is almost never comparable

"They say they can do the migration in eight weeks" is not a statement about eight weeks, it is a statement about a scope you have not seen. Before deciding whether you are beaten, establish what the claim is a claim about, because there are only four possibilities and three of them are recoverable.

The claim may cover different scope, which is much the most common case. It may rest on assumptions the customer has not been shown, such as clean source data or no parallel run. It may be a genuine capability advantage, in which case saying so is your only credible move. Or it may be a commitment the competitor has no intention of honouring, which you cannot prove and must not allege.

Decomposing your own number against theirs, out loud, is what separates the three cases. Using the eight-week migration claim against your own fourteen weeks:

Component	Our basis	Where their eight weeks could come from
Source data profiling and cleansing	15 days, three source systems	Excluded, or assumes you supply clean extracts
Migration tooling build and test	25 days	Reused accelerator, entirely legitimate
Trial loads and reconciliation	20 days, three full rehearsals	One rehearsal rather than three
Parallel run before cutover	4 weeks elapsed	Excluded, cutover is a single event
Closed-record history	included, back to 2019	Deferred, or migrated after go-live

Nothing in that table criticises the competitor. It is your own basis, itemised, and it converts an unmatchable claim into a question about which lines the customer is willing to give up. If their eight weeks turns out to exclude the parallel run and the historic records, you have not lost on migration speed — the two proposals were measuring different things, and the customer now knows it without you having said a word about the other vendor.

What to say while you are still in the room

You will not have the decomposition to hand when the claim lands, so the immediate response is a question and an undertaking, delivered without visible discomfort.

"That is a faster number than ours, so it is worth understanding rather than arguing about. Ours is fourteen weeks and I can tell you exactly what is in it — three reconciliation rehearsals, a four-week parallel run, and closed records back to 2019. If their eight weeks covers all of that, they know something about migration tooling that I would genuinely want to learn. If it does not, the two numbers are answering different questions. Can I send you the itemised basis for ours tomorrow, so you have something to compare line by line?"

Three things are happening in that answer. You have accepted the number rather than flinching, which costs nothing and buys credibility. You have named your own inclusions, so the comparison now has a shape. And you have offered the customer an instrument for interrogating both vendors, which is a service to them rather than an attack on anyone.

Conceding a real advantage

Sometimes the competitor is simply better on that axis, and the answer that works is to say so once, plainly, and then place it in proportion. A vendor who cannot concede a single point is telling the buyer that nothing they say can be trusted, whereas a concession makes every subsequent claim more believable — which is why the concession is a commercial move and not a defeat.

What follows the concession is the part that matters. Establish what the advantage is worth in the customer's own terms: if a six-week saving on a migration sits inside a programme whose date is set by a regulatory deadline eighteen months away, the advantage is real and largely irrelevant, and saying so is legitimate. If it is not irrelevant, then you compete on the criteria where you are strong, and you accept that this criterion is lost rather than spending your credibility defending it.

Do not match a number you cannot deliver

The pressure in the room is to say "we can do that too", and it is the single most expensive sentence available. It survives the meeting and then reappears as a contractual expectation, a delivery commitment nobody sized, and a conversation in month four where the customer produces your own words. Matching also removes your best argument, because a fourteen-week basis you can evidence beats an eight-week claim you cannot, and the moment you claim eight you have nothing left to distinguish you.

If your sales lead matches it before you can speak, do not correct them in front of the customer. Add the condition instead — "and to be precise about what that would require from your side, we would need the extracts profiled before we mobilise" — then resolve it privately and get the correction into the written follow-up the same day.

Never criticise the competitor, and stay accurate about them

Disparagement fails for a mechanical reason: the buyer chose to talk to that vendor, so criticising the vendor criticises the buyer's judgement, and any inaccuracy in your criticism discredits everything else you have said. It also invites the competitor to be told what you said, usually in a distorted form.

The technique that works is to raise the question your strength answers and let it apply to everyone. If reversibility is where you are strong, ask what happens if the cutover has to be reversed at hour six, and how the vendor proposes to prove that before the date. You have not named anyone, the customer will ask it of every bidder, and the answers will differ. Where a direct comparison is unavoidable, quote only their published material and be scrupulously exact about it, because being caught overstating a competitor's limitation costs more than the limitation was worth.

An unmatchable competitor claim is a scope question wearing a number, and the response that wins is your own basis itemised in front of the customer — not a better number, and never a worse word about the other vendor.
