How to Prepare for a Discovery Call: A 30-Minute Checklist

Prepare for a discovery call in 30 minutes: research, goals, question flow, objections and the next step. Includes a checklist and practice tips.

A discovery call is usually your first real conversation with a prospect, and it often decides whether there is a second one. Many sellers either over-prepare (an hour of slide-building) or under-prepare (a quick glance at the LinkedIn profile as the call connects). Neither is ideal.

What helps is a short, structured routine that gets you ready to listen well. This article gives you a 30-minute plan and a checklist you can reuse.

What a discovery call is for

A discovery call is not a demo, and it is not a pitch. Its job is to understand the customer's situation well enough to judge whether you can help, and to agree a next step if you can.

By the end, you should be able to say, in one sentence, what the customer is trying to achieve, what is in the way and why it matters now. If you cannot, the call has not done its job, however pleasant the conversation was.

That gives preparation a clear purpose: not to arm you with things to say, but to help you ask the right questions and to listen to the answers. Insurance and financial advisers know this well; for them, good advice starts with needs, not products, and the same logic applies in most other fields.

The 30-minute preparation plan

Minutes 1-8: research

Collect only what will change your questions.

  • The person. Role, how long they have been in it, anything they have published or shared that suggests priorities.
  • The company. What it does, who it serves, any recent news such as a new product, a hiring push or a change of leadership.
  • The trigger. Why did they agree to this call? Did they reply to an email, attend an event, get referred? Knowing the trigger tells you what is already on their mind.
  • Your history. Any previous contact, notes from colleagues, past proposals.

Write three bullet points, not a dossier. If a fact does not suggest a question, leave it out. The aim is not to impress them with how much you know, but to avoid wasting their time asking what they have already published.

Minutes 9-14: set your call goal and the customer's likely goal

Write two lines.

  1. My goal for this call. Be specific: "Understand their current process and agree a second call with the budget owner" is better than "Qualify".
  2. Their likely goal. What do they probably hope to get from it? Perhaps to check whether you are credible, to compare options or just to be polite. Guessing helps you open in a way that matches their mood.

Also decide what a good outcome and an acceptable outcome look like. A call that ends with "this is not a fit" and a clear reason is a perfectly good discovery call: it saved both sides time.

Minutes 15-22: plan your question flow

Do not write twenty questions. Draft a flow of five to seven, in a logical order, and expect to improvise around them.

A simple structure:

  1. Situation. How things work today.
  2. Problem. What is not working, or what they would change.
  3. Impact. What that costs them, in time, money or stress.
  4. Priority. Why it matters now rather than later.
  5. Decision. Who else is involved and how decisions are made.
  6. Next step. What would be a sensible follow-up.

Open questions ("How does that work at the moment?") usually yield more than closed ones ("Do you use X?"). Prepare follow-ups too, such as "Tell me more about that" and "What happened next?" These matter more than the prepared questions, because they show you are listening.

If you want a quick way to turn this into a first draft, the call script generator may help; edit whatever it produces so it sounds like you.

Minutes 23-27: anticipate objections

Discovery calls have their own typical objections, which are different from late-stage ones:

  • "I only have ten minutes."
  • "Can you just send me some information?"
  • "We already have someone for that."
  • "I'm not the right person."
  • "We have no budget right now."

For each, prepare a short reply that acknowledges, then asks. For example, to "I only have ten minutes": "Understood. Let me use them well: what would make this call worthwhile for you?" Keep replies to one or two sentences. The objection catalogue is a good place to find more objections to prepare for.

Minutes 28-30: decide the next step

Before you dial, decide what you will propose at the end: a second call, a demo with a colleague, a trial, a written proposal. Think of the specific wording and a date: "Would Thursday at ten work for a thirty-minute follow-up with your finance lead?"

Calls that end with "I'll be in touch" tend to fade. Calls that end with a specific, agreed action tend to continue. Write the sentence you will say, and keep it in front of you.

Questions worth preparing

Here are some examples you can adapt, grouped by purpose.

Understanding the situation

  • "Can you walk me through how this works today?"
  • "What does a typical week look like for your team on this?"

Finding the problem

  • "What's working well, and what would you change if you could change one thing?"
  • "Where does this tend to go wrong?"

Exploring impact

  • "What does that mean for you in practice?"
  • "How does that affect the people around you?"

Establishing priority

  • "What made this a priority now?"
  • "What happens if nothing changes?"

Clarifying the decision

  • "Who else would want to weigh in?"
  • "How have you made similar decisions before?"

Do not ask them all. Choose the few that fit this customer.

Mistakes that waste a discovery call

  • Pitching too early. If you describe your product in the first five minutes, you will anchor the call on features instead of needs.
  • Asking from a checklist. Customers can tell. Follow their answers.
  • Talking more than half the time. In a discovery call, aim to listen far more than you speak.
  • Skipping the summary. Near the end, reflect back what you heard: "So the main issue is X, it matters because Y, and you would like to solve it by Z. Have I got that right?" Correcting you is easy for the customer, and it builds trust.
  • Leaving without a next step. Always propose one, even if it is "we agree this is not a fit".
  • Criticising the current provider. Ask what they would change instead.

Practise the first five minutes aloud

Preparation on paper is not the same as being ready to speak. The first five minutes set the tone for the whole call, so rehearse them out loud: your opening, your first two questions, and your reply to "I only have ten minutes".

You can do this alone: say it standing up, record yourself on your phone, and note one thing you would say differently. The 10-minute practice guide shows a way to structure it.

If you would like a customer who answers back, a voice practice tool helps. In DIRI AI, you pick a situation such as a first meeting, set the difficulty and speak to an AI client that responds to what you say. Afterwards, the report highlights key moments and suggests one thing to try next; the sample call and report page show what that looks like, including skill areas such as needs discovery and active listening. Sellers can read more on the for sellers page, and advisers on the page for insurance advisers.

After the call

Preparation continues once the call ends. Within ten minutes:

  1. Write down what you learned in the customer's own words.
  2. Note anything that surprised you.
  3. Record the agreed next step and send a short confirmation.
  4. Write one thing you would do differently on the next discovery call.

That last note is your practice goal for next time. The guide on turning feedback into a practice goal explains how to keep it small and specific.

The checklist

Copy this before each call:

  • Three bullet points of research, each linked to a possible question
  • The trigger: why they agreed to the call
  • My goal for the call (specific)
  • Their likely goal
  • Five to seven questions in a logical flow, with follow-ups
  • Replies ready for the three objections I expect
  • The next step I will propose, with a date
  • Opening spoken aloud at least twice
  • Notes template ready for afterwards

Thirty minutes of this is usually enough. Anything beyond it often becomes procrastination.

If you want to rehearse the opening of your next discovery call, DIRI AI has a free plan: 3 voice calls a month of up to five minutes each, with a basic report (score and one tip) afterwards and no card needed. Start free, choose a first-meeting scenario and try your opening before the real one.
