The most widely used sales methodologies are SPIN Selling, the Challenger Sale, the Sandler Selling System, Solution Selling, MEDDIC and BANT. They answer different questions: SPIN, Challenger, Sandler and Solution Selling describe how to run the conversation, while MEDDIC and BANT describe how to qualify a deal. Most teams pick one conversation method and one qualification framework, and match both to their deal size and sales cycle.

This guide compares the six side by side: where each came from, the core idea, what it's best for, a sample line and the common mistake, plus how to choose one and roll it out.

## What is a sales methodology?

A sales methodology is a set of principles and techniques that guide how sellers think and talk at each stage of a deal. A sales process is the sequence of stages a deal moves through (prospect, discovery, demo, proposal, close). The process says *what* happens next; the methodology says *how* you handle each step.

You can run the same sales process with different methodologies. A team might use the same five stages but coach reps on SPIN questions in discovery and MEDDIC for forecasting.

## How do the main sales methodologies compare?

| Methodology | Origin | Core idea | Best for |
|---|---|---|---|
| SPIN Selling | Neil Rackham, Huthwaite; book 1988 | Ask Situation, Problem, Implication and Need-payoff questions | Complex B2B sales with long discovery |
| Challenger Sale | Matthew Dixon and Brent Adamson, CEB; book 2011 | Teach the buyer something new, tailor it, take control | Sophisticated buyers and crowded markets |
| Sandler Selling System | David Sandler, 1967 | Qualify hard, use upfront contracts, let the buyer sell themselves | Teams that waste time on unqualified deals |
| Solution Selling | Mike Bosworth; book mid-1990s | Diagnose the buyer's pain, then sell a solution to it | Products that solve a clear business problem |
| MEDDIC | PTC, 1990s | Qualify deals on six criteria | Complex deals with several stakeholders |
| BANT | Commonly credited to IBM | Check budget, authority, need and timeline | Fast lead qualification and SDR handoffs |

## What are the main sales methodologies?

### What is SPIN Selling?

**SPIN Selling** is a questioning method built on four types of questions: Situation, Problem, Implication and Need-payoff. It comes from Neil Rackham and the Huthwaite research team, who studied 35,000 sales calls over 12 years before publishing *SPIN Selling* in 1988 ([background on Wikipedia](https://en.wikipedia.org/wiki/Neil_Rackham)).

- **Core idea:** in larger sales, buyers convince themselves when your questions help them see the consequences of a problem (implication) and the value of solving it (need-payoff).
- **Sample line:** "If new reps keep taking four months to ramp, what does that do to your hiring plan for next year?"
- **Common mistake:** spending the whole call on situation questions. Buyers get bored answering things you could have researched.

### What is the Challenger Sale?

**The Challenger Sale** argues that top performers teach buyers something new about their business, tailor the message to each stakeholder, and take control of the conversation. It comes from research by Matthew Dixon and Brent Adamson at CEB (now part of Gartner), published as *The Challenger Sale* in 2011. Their survey of thousands of reps sorted sellers into five profiles, and the Challenger was the profile most often found among high performers ([Salesforce summary](https://www.salesforce.com/ca/blog/challenger-sales-model/)).

- **Core idea:** teach, tailor, take control. Lead with an insight that reframes how the buyer sees their problem.
- **Sample line:** "Most teams think ramp time is a training problem. What we see is that it's a practice problem: reps know the material but have never said it under pressure."
- **Common mistake:** confusing "challenging" with arguing. The insight has to be relevant and backed up, not contrarian for its own sake.

### What is the Sandler Selling System?

**The Sandler Selling System** is a qualification-first method created by David Sandler in 1967. It uses the image of a submarine: you secure each compartment (stage) before moving to the next, so a deal can't sink because you skipped one ([Gong overview](https://www.gong.io/blog/sandler-selling-method)).

- **Core idea:** qualify hard, agree on upfront contracts at the start of every meeting, uncover pain, and let the buyer reach their own conclusions instead of being "sold."
- **Sample line:** "Before we start, let's agree on what happens at the end of this call: either we both see a fit and book a next step, or we agree it's not right. Fair?"
- **Common mistake:** using Sandler's techniques as tricks. Done cynically, the "reverse" moves feel manipulative.

### What is Solution Selling?

**Solution Selling** focuses on diagnosing the buyer's business pain and positioning your product as the solution to it, rather than selling features. It's associated with Mike Bosworth, whose book *Solution Selling* was published in the mid-1990s.

- **Core idea:** no pain, no sale. Diagnose first, then present a solution tied to the diagnosis.
- **Sample line:** "Before I show you anything, can you walk me through what happens when a new rep starts?"
- **Common mistake:** assuming the pain instead of uncovering it. "You probably struggle with X" isn't diagnosis.

### What is MEDDIC?

**MEDDIC** is a qualification framework for complex B2B deals: Metrics, Economic buyer, Decision criteria, Decision process, Identify pain and Champion. It's usually credited to sales leaders at PTC in the 1990s.

- **Core idea:** you can only forecast a deal honestly when you understand all six.
- **Sample line:** "Who signs off on something like this, and what will they want to see?"
- **Common mistake:** treating it as a form to fill in rather than a set of things to actually find out. Our full [MEDDIC guide](https://klu.so/blog/meddic) has questions and a worked example.

### What is BANT?

**BANT** checks four things: Budget, Authority, Need and Timeline. It's commonly credited to IBM and is the quickest of these frameworks.

- **Core idea:** don't spend time on leads that can't or won't buy soon.
- **Sample line:** "Is there a date or event this needs to happen by?"
- **Common mistake:** asking about budget first, which makes the call feel like a credit check. Our [BANT guide](https://klu.so/blog/bant) suggests a better order.

## How do you choose a sales methodology?

Ask four questions about your deals:

| Question | If the answer is... | Consider |
|---|---|---|
| How big and complex are your deals? | Large, many stakeholders | MEDDIC for qualification, SPIN or Challenger for conversations |
| How long is your sales cycle? | Short and transactional | BANT plus simple discovery questions |
| How sophisticated are your buyers? | Experienced, well researched | Challenger |
| Where do deals stall? | Lots of time spent on deals that never close | Sandler and stricter qualification |

## Can you combine sales methodologies?

Yes, and most teams do. A common setup is BANT for SDR qualification, SPIN-style questions in discovery (see our [discovery call guide](https://klu.so/blog/discovery-call)), and MEDDIC for deal reviews and forecasting. The conversation method and the qualification framework do different jobs, so they fit together.

What doesn't work is switching every quarter. A methodology takes months of consistent coaching before it changes how reps actually sell.

## How do you roll out a sales methodology?

1. **Pick one methodology and one qualification framework.** Not three of each.
2. **Teach one skill a week.** For SPIN, that might be implication questions one week and need-payoff questions the next.
3. **Practice out loud.** Reps need to say the new questions dozens of times before they use them naturally on a call. Structured [sales role play](https://klu.so/blog/sales-role-play) helps, and on [Klu](https://klu.so) reps can practice calls out loud with an AI buyer and get coached on the exact line to change.
4. **Use the language in deal reviews.** If managers ask "who's the economic buyer?" in every pipeline meeting, reps learn to find out.
5. **Review real calls.** Pick one call a week and look for the methodology in action, or missing.
