21 Discovery Call Questions That Close Deals (Solo Seller Cheat Sheet)

The Discovery Call Questions Every Solopreneur Should Have Ready

Most discovery calls go sideways not because the solopreneur lacks skill, but because they wing it. They hop on a call, chat for 45 minutes, and walk away with a vague sense that it went "pretty well" but no clear next step.

This post is a working reference you can keep open during calls. The questions are grouped by phase, so you can move through a conversation with intention rather than just hoping the right topics come up naturally. If you're looking for more practical sales content for solo operators, the Ungrind blog covers this territory regularly.

These are the exact types of questions that separate a productive discovery call from a friendly chat that goes nowhere. Bookmark this. Come back to it before your next call.

Phase 1: Opening (Build Rapport and Set the Tone)

The first few minutes of a call set the emotional temperature for everything that follows. Your goal here is not to impress the prospect. It's to make them feel comfortable enough to be honest with you.

Rapport doesn't mean small talk about the weather. It means showing genuine curiosity about the person before you start asking them to reveal their business problems.

Questions to Ask

1. "How did you first hear about what I do, and what made you want to get on a call?" This tells you their awareness level and their motivation in one shot. Someone who found you through a referral is in a very different mindset than someone who clicked a cold email.
2. "What does your role look like day-to-day? Are you the one making decisions here, or are others involved?" Ask this early and you avoid the painful moment at the end of the call when you realize you've been pitching to someone who can't say yes.
3. "Before we get into it, is there anything specific you were hoping to cover today?" This hands control to the prospect for a moment and signals that you're not just there to run through a script.
4. "How much time do you have set aside for us today?" Simple, but it prevents the call from running over and it tells you how deep you can go in the time available.

What You Learn From This Phase

By the end of the opening, you should know who you're actually talking to, how they found you, what they're hoping to get from the call, and how much runway you have. You'll also have a gut sense of whether they're engaged or guarded, which shapes how you approach the next phase.

Phase 2: Qualifying (Budget, Timeline, and Fit)

This is the phase most solopreneurs rush or skip entirely because it feels awkward to talk about money. Don't skip it. Spending an hour with someone who can't afford you or isn't ready to move forward is a cost you pay with time you won't get back.

Qualifying isn't about being transactional. It's about respecting both your time and theirs.

Questions to Ask

5. "Have you worked with someone like me before, or is this a new type of investment for you?" This tells you whether they already understand the value of what you do or whether you'll need to do more education.
6. "Do you have a budget in mind for solving this problem?" Ask directly. Most prospects have a number in their head. Some won't share it, but many will. Either way, you've opened the conversation.
7. "What happens if you don't solve this in the next few months?" This is a soft timeline question that also starts surfacing urgency. If the answer is "nothing much," that's useful information too.
8. "Are you actively looking at other options right now?" Knowing whether you're one of several options helps you understand how competitive the situation is and how much the prospect has already thought this through.
9. "What does your decision-making process look like? Is there a formal approval step?" For solopreneurs selling discovery call questions often miss this one. Knowing the decision process prevents you from being blindsided by a "I need to check with my partner" at the end.

What You Learn From This Phase

After qualifying, you should have a clear sense of whether this person can buy, whether they're ready to buy soon, and who else is involved in the decision. If any of those three are missing, your job in the next phase is to either uncover them or accept that the timing might not be right.

Phase 3: Pain Discovery (The Heart of the Call)

This is where the real work happens. Pain discovery is the reason discovery calls exist. You're not just collecting information here. You're helping the prospect articulate something they may not have fully put into words before.

When someone feels genuinely heard and understood, they trust you more. That trust is what makes the difference between a prospect who ghosts you and one who replies to your follow-up within the hour.

For solopreneurs running discovery calls without a team behind them, this phase is especially important. You don't have a sales manager reviewing your calls or a colleague to debrief with. You need to extract enough information in real time to write a compelling proposal on your own.

Questions to Ask

10. "Walk me through what's been happening. What made this a priority right now?" Open-ended and inviting. Let them talk. Resist the urge to jump in with solutions.
11. "How long has this been a problem?" Duration tells you how entrenched the issue is and how much patience they have left for it.
12. "What have you already tried?" This prevents you from proposing something they've already attempted. It also shows you've done this before and aren't going to waste their time with obvious suggestions.
13. "What did those attempts cost you, in time, money, or both?" This question starts building the case for your value without you having to make it directly.
14. "What's the impact of this problem on your work or your clients?" Move from the problem itself to the downstream effects. This is where emotional weight lives.
15. "If you could wave a wand and have this fixed tomorrow, what would that look like?" This reveals their ideal outcome in their own words, which you can then reflect back in your proposal.
16. "What would solving this make possible for you that isn't possible right now?" Future-state thinking. This is the question that gets people excited rather than just frustrated.
17. "Is there anything about this situation that you haven't mentioned yet that I should know?" You'd be surprised how often this one unlocks something important that the prospect assumed wasn't relevant.

What You Learn From This Phase

By the end of pain discovery, you should be able to summarize the prospect's problem back to them more clearly than they articulated it themselves. If you can do that, you've done your job. You'll also have the raw material for a proposal that speaks directly to what they actually care about, not what you assumed they cared about.

Phase 4: Closing the Call (Next Steps, Not Pressure)

Closing a discovery call doesn't mean closing a sale. It means closing with clarity. Both of you should leave the call knowing exactly what happens next and when.

This is where a lot of solopreneurs lose deals they should win. The call goes well, there's genuine connection, and then it ends with a vague "I'll send something over" and no agreed follow-up date. That gap is where deals go to die.

Questions to Ask

18. "Based on what we've talked about, does this feel like a good fit from your side?" Give them permission to say no. If they're not feeling it, better to know now. If they are, this confirms momentum.
19. "What would you need to see in a proposal to feel confident moving forward?" This is one of the most underused discovery call questions for solopreneurs. It tells you exactly what to prioritize when you sit down to write.
20. "What's your timeline for making a decision?" Ask again here, even if you touched on it in qualifying. The answer sometimes changes once the conversation has gone deeper.
21. "Can we schedule a follow-up call now so we have it on the calendar?" Book the next step before you hang up. Every time you leave this to email, you add friction and delay.

What You Learn From This Phase

You leave the call with a clear next step, a date on the calendar, and a sense of what the prospect needs to feel good about saying yes. That's the difference between a discovery call that generates momentum and one that generates a proposal that never gets a response.

A Note on Actually Remembering What Was Said

Even with a great set of questions, it's easy to lose the details. You're managing the conversation, watching the clock, thinking about what to ask next. Taking notes while staying present is genuinely hard.

This is one of the reasons some solopreneurs use tools like Ungrind, which sends an AI meeting bot to join your Google Meet or Teams calls, transcribes everything, and automatically creates follow-up tasks and a meeting summary. Instead of frantically typing during the call, you can focus on actually listening. The notes are there when you need them.

Whether you use a tool like that or just a well-organized notes doc, the point is to have a system so that the insights from your discovery calls don't evaporate the moment you close the browser tab.

How to Actually Use This List

You're not going to ask all 21 questions on every call. A good discovery call is a conversation, not an interrogation. Pick the questions that feel most relevant to the prospect you're meeting, and let the conversation breathe.

A practical approach: print this list or keep it open in a second tab. Before the call, highlight the five or six questions you most want to cover. Use the rest as backup if the conversation stalls or takes an unexpected turn.

The goal is to finish every discovery call knowing whether the prospect is a real fit, what their actual problem is, and what the next step looks like. These 21 questions are designed to get you there without making the call feel like a form you're filling out.

If you want to compare how different CRM tools handle the follow-up side of discovery calls, the Ungrind vs HubSpot comparison breaks down the differences for solo operators specifically.

Try It on Your Next Call

Pick your next scheduled discovery call and run through this list beforehand. Choose your questions, set your intention for each phase, and see how different the conversation feels when you have a structure to fall back on.

If you want a tool that handles the note-taking and follow-up automatically so you can focus on the questions that matter, Ungrind offers a 30-day free trial with no credit card required. It's built for solopreneurs who run their own calls and don't have a team to cover the admin afterward.
