28 Questions Every Sales Rep Should Ask on a Discovery Call

Do you truly control the rhythm of a sales conversation with a prospect — or are you just following their lead, always performing on their turf? If it’s the latter, the outcome is predictable: a whole lot of activity with very little to show for it.

Sales reps spend a great deal of time managing relationships — making calls, nudging deals forward, closing orders, collecting commissions. On the surface it all feels productive. But elite salespeople actually control the sales process. They know exactly which prospects are worth their time, which products and services are the right fit, what deal sizes to expect, and how long a cycle will run. They can answer every open question in the process. Average reps just go through the motions. That’s why Knight put together this guide: a practical look at the questions every sales rep should be asking and uncovering during a discovery call.

What Is a Discovery Call?

In many cases, the first call after initial contact with a prospect is the single most important conversation in the entire sales cycle. It determines whether a lead is worth pursuing at all — and if so, where that prospect sits in the buying journey. It sets the tone for everything that follows. There are two ways to build a relationship with a prospect: as a trusted, credible advisor, or as someone perpetually chasing them and hoping for a callback.

We’ve found that as long as the call doesn’t feel like an interrogation, most prospects are quite willing to answer questions about their project or initiative over the phone. Getting a clear picture of the prospect’s situation during this call is critical. When a sales rep masters flexible, conversational discovery techniques, the process becomes genuinely enjoyable for both sides — while still achieving its business purpose.

From the prospect’s perspective (many prospects haven’t even clarified what they want yet — which disqualifies them as true opportunities, and is exactly why Knight advocates so strongly for inbound marketing), a genuine prospect wants to learn more about you and your company. They’re evaluating whether your offering fits their needs, and how well you understand their problem. At minimum, any competent sourcing exercise requires thorough vendor due diligence before reporting back to leadership — time spent on this call is not wasted.

Prospects need to feel confident that you understand their challenges and that you can offer a credible, expert assessment of how you can help.

From the company’s perspective, inbound marketing strategies should be used to gather and validate intelligence about every prospect. Beyond that, the discovery call needs to confirm the prospect’s business pain points, assess the contact’s internal influence, and gauge their initial openness to purchasing your solution versus a competitor’s. Sales reps must remember that every interaction with a prospect needs to be a two-way exchange — not a one-sided sprint where your whole team races to prepare, only to hear “thanks, we’ll be in touch” at the finish line. That kind of visible and hidden cost is something no company wants to absorb.

Below is the list of discovery questions we use most often. You won’t always get through all of them on a single call — and guiding a prospect to answer as many as possible is itself a measure of sales skill — but working through these questions will help you distinguish qualified prospects from those not worth your time and resources.

The Customer Value Discovery Process

The discovery process is the first real touchpoint in a sales relationship. Through this process, the rep builds an understanding of the prospect’s value by asking targeted questions, answering the prospect’s questions in return, looping in key project stakeholders from the prospect’s side, and engaging their senior decision-makers. The goal is to guide the prospect onto your playing field — controlling the frame of the conversation matters enormously.

Based on the question list above, the discovery process can be broken down into four execution phases: Prospect Profile Fit, Problem Validation, Qualification & Prioritization, and Next Steps Planning.

Phase 1: Prospect Profile Fit

This is your opportunity to assess whether the prospect is actually a good fit for your product or service — and to gather the context you need to serve them well.

1. Ask about the company’s business scope and current situation.
2. Ask about the contact’s role, responsibilities, and day-to-day work.
3. Ask what the contact’s specific responsibilities are within this project.

Phase 2: Problem Validation

Once you have a basic understanding of the prospect, dig deeper into their goals and pain points. The more you understand them, the better positioned you are to help — both them and yourself.

1. Ask about the contact’s professional goals.
2. Ask about the timeline and plan for achieving those goals.
3. Ask what problem they are trying to solve.
4. Explore how that problem relates to your product or service.
5. Try to understand the root cause of the problem.
6. Ask why solving this problem has become a priority now.
7. Ask why the problem hasn’t been addressed previously.
8. Ask what solution the contact thinks might work, and why.
9. Ask what a successful outcome would look like to them.
10. Ask whether they plan to address this problem even if they don’t purchase your product.

Phase 3: Qualification & Prioritization

At this stage, ask questions that help you decide whether this prospect is worth continued investment and follow-up.

1. What are the biggest obstacles to moving this initiative forward?
2. What is the implementation timeline?
3. What is the budget situation for this project?
4. Where is the project budget coming from?
5. Is the budget holder also the project sponsor?

Phase 4: Next Steps Planning

Finally, ask guiding questions that help steer the prospect toward a clear path forward — one you’re shaping.

1. Who else will be involved in the vendor selection process?
2. Are there written vendor selection criteria for this project? Who created them?
3. Has the company purchased similar products or services in the past?
4. Is this a competitive bid with three or more vendors?
5. What does the decision-making process look like? Are compliance or procurement reviews involved?
6. What are the key obstacles to moving the project forward?
7. How can a vendor help make the process smoother?
8. What kind of solution would genuinely help the business?
9. What are the company’s goals for this year?
10. If this solution is implemented, what ROI does the company expect to see?

If you and your prospect can end the call with a clear, written project plan and concrete next steps, that’s a strong signal — and a solid first-call win. If questions remain after hanging up, schedule another call to work through the remaining details. Of course, B2B buying decisions involve many variables and long cycles. Decision-making teams typically consist of 6 to 10 people, and the person you’re speaking with on a first call is often doing early-stage vendor research — senior stakeholders may have already shifted direction without telling their own team. That’s why sales reps need to keep using probing, discovery-oriented conversation techniques to ask, assess, and advance every deal. For a more rigorous and data-driven way to evaluate prospect quality, combine these conversations with Knight’s lead scoring system, which tracks both explicit and behavioral signals. — Download the “Lead Behavior Scoring Playbook” now.

Across all four phases, we recommend prioritizing qualification questions — specifically those that determine whether a prospect is worth further investment — over purely descriptive or validating questions. Procurement and legal terms rarely block a deal on their own (unless a prospect is using them as an excuse to stall). What actually matters is a confirmed project plan, a real budget, and a clear timeline.

In an ideal world, a single discovery call gives you a definitive answer: this is a genuine sales opportunity, or it isn’t. In reality, sales outcomes are shaped by many complex and overlapping factors, and relying solely on a rep’s subjective judgment isn’t always reliable. We advocate for blending objective data into the picture as well — Knight can instrument your campaigns at no cost so you have real attribution data to back up your qualitative assessment.

Knight Tip: Never leave a call without offering the prospect something genuinely useful — a piece of advice, a relevant insight, or a helpful observation. If you leave them with a positive, professional impression, you’ll be the first person they call when they’re ready to buy.
