How to respond when a customer already has a supplier (with a scored example)

Written by Toby Sinclair

Updated

Key takeaways

Do not badmouth the incumbent. It makes you the risk.

Ask what is working and what they would change if they could.

A next look at renewal is a result. A dump of features is not.

If there is no gap, leave cleanly. You can be second without being desperate.

When they say they already have a supplier, believe them. Do not pitch over the top of a contract they are not going to tear up on a Tuesday. Ask what is working, what they would change, and when the arrangement next comes up. If there is a gap you can honestly fill, offer a dated comparison — not a smear. If there is no gap, thank them and leave a short way back. Panic pitching against an incumbent teaches them you did not listen. Composure is the first commercial move.

Pair this scored attempt with the matching guide. These conversations also run on the Real Talk Studio platform.

1. Composure is the first commercial move

An incumbent is not an insult. It is the default. If you flinch into “but we are better,” you have started a fight with someone who is not in the room. Thank them for being direct. Repeat that you are not asking them to rip anything up today. Then get curious about the relationship they already have: term, service, the person who actually picks up. A lot of “we are happy” is inertia. Some of it is real satisfaction. You will not find out which by listing modules. You find out by letting them talk.

2. Value is the gap they will admit, not a brochure of features

Ask what they would change if they could do it without a migration headache. Ask what happens when something breaks. Ask who else uses it. The gap might be price, might be a person who left, might be a report the board now wants. Speak to that. Switching cost is real — do not pretend it is not. The customers who move are rarely the ones who were shouted at with a feature matrix. They are the ones who felt you understood the incumbent well enough to be a safe second conversation, not a raid.

3. A next step beats a hero pitch

If renewal is in November, ask for a short comparison in October. If they will not give a date, ask what would have to be true for a look to be worth it. Put it in writing the same day: what you heard, what you would show, the date. If they say never, close the file with dignity. Staying on a weekly drip against a locked incumbent is how you become the vendor they dodge. The ones who only wanted a cheaper quote will still want that later. You will not have bought it by trashing their current supplier on this call.

4. Map the term before you map your product

Ask when the arrangement next comes up, whether there is a break clause, and who signs. Write those dates down. A brilliant pitch in month two of a three-year deal is entertainment. A comparison ninety days before renewal is work. If they do not know the date, that is information too — they may not own it. Ask who would know. Offer to be useful to that person rather than loud to this one. Incumbents survive because someone already did the political work of getting them in. You will not undo that with enthusiasm. You might undo it with a diary date and a page that helps them look without looking disloyal.

5. If you move, move on a gap they named, not on a smear

The gap might be a person who left, a report the board now wants, a price that only works until November. Speak to that. Do not tell them their supplier is about to fail. You do not know, and it makes you the risk. If you have a reference in the same industry, offer it as a conversation, not as a prosecution of the incumbent. People who feel you respect the choice they already made will sometimes let you in at the edge. People who feel raided will tell the incumbent you called. That is how doors close for a cycle. Dignity is a commercial tactic. Use it.

6. Leave a way back that does not drip

A short note the same day: what you heard, the date you proposed, one line they can forward. Then stop. Weekly “just checking in” against a locked incumbent is how you become the vendor they screen. If they said never, believe them. If they said October, put October in your calendar and go quiet. Silence with a date is professional. Noise without a date is why people say they already have a supplier even when they might have looked. Earn the look by not punishing the incumbent sentence.

Mistakes that turn an incumbent into a slammed door

Attacking the supplier they chose. Asking them to forward the contract in the first five minutes. Offering a discount before you know the term. Talking over “we are happy” with a case study. Practise the line you will need: “I am not asking you to move today. When does this next come up, and what would be worth putting in front of you then?” If you cannot say that under a brisk brush-off, you will pitch, they will say send an email, and you will have neither a date nor a relationship.

What to say

Respect the incumbent. Find the gap. Book the look.

You

I am not asking you to rip anything up today. You already have a supplier — that is useful to know.

You

What is working, and what would you change if you could do it without a migration headache?

You

When does this next come up? I can put a one-page comparison in front of you ninety days before, aimed at the gap you just named — not a raid.

If they say this

They say

We are happy. There is no point talking.

You say

Then I will not pitch you a deck. If “happy” still has a renewal date, I will take that date and come back with one page. If it is never, I will leave a way back and stop.

Do not raid. Take a date or a clean no.

They say

If you are cheaper I might look. I am not doing a switch project.

You say

I will not pretend switching is free. If price is the gap, I can send a comparison that includes the work of moving, not a headline that ignores it.

They named the constraint. Speak to it. Do not oversell ease.

They say

Our supplier would kill us if they knew we were talking.

You say

Then I will not make a noise you have to explain. A dated, quiet comparison is the most I will offer. I will not use your name as a logo.

Disloyalty fear is real. Offer safety, not a case study.

Quiet same-day note

What you heard, the date, one page later. No smear.

Hi Sarah,

Thank you for being direct — you already have a supplier and you are not looking for a raid.

You said renewal is in November and the gap worth a look is reporting for the board. I will send a one-pager in October, aimed at that, not a feature list. I will not contact you weekly in the meantime.

Leila Haddad

Hi — you wanted to talk?

Account Executive

Thanks, Leila—I'll keep this brief.

Leila Haddad

Appreciate that. Just so we're clear, we're pretty settled on tooling, unless something's broken.

Account Executive

Is there anything that’s been bugging you lately, or are things running as expected?

Leila Haddad

We had some noise on alerts last night, but honestly, that's mostly operator error. Nothing that justifies a change project right now.

Account Executive

That makes sense—no reason to stir things up if you’re not hearing real pain.

Leila Haddad

Exactly. But thanks for checking in—I’ll reach out if that changes after renewal.

Frequently asked questions

What if they are in a long contract?
Then today’s win is a diary date, not a signature. Ask when it ends and what a useful comparison would look like ninety days before.
Should I ask who the supplier is?
Yes, calmly. You are mapping the landscape, not collecting gossip. If they will not say, work with the gap instead.
Is it ever right to pitch the full deck anyway?
Almost never in the first answer. A deck they did not ask for is proof you did not hear “we already have someone.”
What if they hint the incumbent is failing?
Slow down. Get the failure in their words. Offer a scoped look, not a victory lap. Desperation to pounce reads as a raid.
What if they will not give a renewal date?
Ask who would know. If nobody will say, leave the short way back and stop. Inventing a nurture sequence is how you become the call they dodge.
