A first real discovery call with a B2B buyer, 30 to 45 minutes, where you need to learn enough to know if and how you can help.

A good discovery call follows an arc. You prepare, open so the buyer feels in control, agree what good looks like, diagnose the problem properly, and only then talk about a fix. The rule under all of it: diagnose before you prescribe. Prescribing a solution before you understand the problem is malpractice. Buyers do not care about features, they care about whether you can actually help, and they decide that from how well you understand their world. This is the flow meritt teaches and the one Will has run for years.

Where it goes wrong

Skip the arc and you pitch too early, the buyer goes quiet, and you leave with a vague "send me some info" and no real next step. You never learn the one thing that would have won or saved the deal.

What you'll be able to do

You can run a discovery call end to end, hold the line on diagnosing before prescribing, and leave with a clear, agreed next step.

How to do it

Prepare

Prepare. Two minutes - their role, their company, one genuine point of connection or a prior conversation. Enough to show you actually care.

Open so they lead

Open so they lead. A short opener that thanks them, checks how long they have, and agrees what they want from the call. Invite them to interrupt. This is the ACE open - see the ACE opener lesson.

Agree what good looks like

Agree what good looks like. Ask everyone on the call "what do you want to get out of today?" Write it down and steer by it.

Diagnose in order - situation, pain, proof, value

Diagnose in order - situation, pain, proof, value. Ask how things work today, draw out what actually hurts, share one short story of a similar customer with the same pain, then get them to size what fixing it is worth. Summarise what you heard before you move on.

Prescribe last, and only what fits

Prescribe last, and only what fits. Tie one or two things you do to the pain they named, then lock a concrete next step with a date and a name.

See the difference

Weak

Rep opens with "let me walk you through who we are," spends ten minutes on slides, asks two shallow questions, and ends with "I'll send a deck over." No next date.

Strong

Rep thanks them, checks they still have 30 minutes, says "I want this to be useful for you, so I'll ask more than I tell - jump in any time." Asks what they want out of the call, digs into how things work today and where it hurts, summarises it back, then says "based on what you said about renewals, here is the one thing I'd show you next - can we get 30 minutes Thursday with your ops lead?"

You can run a discovery call end to end, hold the line on diagnosing before prescribing, and leave with a clear, agreed next step.

How you'll know it's working

You have got it when you can run a full call, the buyer does most of the talking, and you leave with a dated next step tied to a problem they named themselves.
