Sales Process

The buyer doesn’t have the numbers. That’s your job.

The Surface-Size-Monetize framework for quantifying impact on the call itself — without waiting for an analysis that’s never going to arrive.

The mistake 80% of reps repeat

There’s a sentence that comes up often after discovery calls: “the buyer told me they don’t have a clear number for the impact.” And after that sentence, the rep waits. Waits for the buyer to do the analysis, to show up to the next meeting with data, with a spreadsheet, with something that justifies the investment internally.

That analysis almost never arrives. The deal goes cold, follow-ups dry up, and weeks later the rep concludes that the prospect “wasn’t ready” or that “the timing wasn’t right.”

That conclusion is wrong. The deal didn’t fall apart because the buyer wasn’t ready. It fell apart because nobody built the business case with them. And that is the rep’s job, not the buyer’s.

Why the buyer doesn’t build the number

Buyers have the pain. They have the intuition that something isn’t working the way it should, the accumulated frustration of dealing with the problem week after week, the pressure from their own managers for results that aren’t coming. What they don’t have is time, methodology, or enough distance to turn that frustration into a number they can defend in front of their own committee.

Turning a pain into a quantified business case requires a synthesis effort that the buyer has no incentive to do alone. It means connecting dots that are hard to see from the inside, and structuring them in a way that convinces someone who doesn’t live the problem every day.

Reps who understand this don’t come to the call to present their value proposition. They come to build the buyer’s business case, using the buyer’s own words and the buyer’s own data. That’s what turns “I’m not sure the impact justifies the cost” into “I need to present this internally this week.”

Surface-Size-Monetize: three steps, one business case

The framework isn’t a new or complex methodology. It’s a sequence of three questions — each one a distinct phase of the conversation — that turns a vague pain into a concrete number the buyer built themselves:

Surface

Move from the abstract symptom to the specific, observable behavior.

Size

Put scale to it: frequency, volume, people affected — using the buyer’s own numbers.

Monetize

Convert that scale to time or money, through questions that lead the buyer to do the math out loud.

The order matters. Skipping Surface to jump straight to Monetize produces numbers the buyer doesn’t feel are theirs, and that don’t survive the second internal meeting. The sequence can’t be reversed without losing the credibility of the result.

The number the buyer builds survives the approval process. The one the rep builds doesn’t.

Surface: bringing the problem to the surface

Most buyers come to the conversation with a problem expressed in general terms: “there’s a lot of friction in the process,” “the reps aren’t doing things right,” “conversion isn’t where it should be.” That level of abstraction isn’t enough to build anything concrete on. Before asking how much the problem costs, you need to know exactly what problem you’re talking about.

Surface is the set of questions that move from symptom to observable behavior:

Question 1

“In what specific situation does this problem appear? Give me a recent example.”

Question 2

“When was the last time this impacted a real outcome? What exactly happened?”

Question 3

“What does the team do today to work around this? How much time does it take them?”

The goal isn’t to get a more elaborate complaint. It’s to get a concrete description of a specific behavior that can be observed, counted, and — eventually — valued in money. Without that specificity, the next two phases have no foundation to build on.

Size: putting scale to the pain

With the problem already surfaced, the next question is how often it happens. Not as the rep’s estimate, but as a number the buyer builds out loud during the conversation. The difference is critical: a number that comes from the rep is a projection the buyer can challenge; a number the buyer built themselves is one they’ll defend internally.

Question 4

“How many times a week does this happen across the team?”

Question 5

“What percentage of deals are you seeing this pattern in?”

Question 6

“How many reps on the team are directly affected?”

A rep who skips Size leaves the buyer with a sense of the problem — something diffuse that creates discomfort but is hard to prioritize against other urgent things. A rep who doesn’t skip it leaves them with a number. And with a number, the buyer can go talk to their manager.

Monetize: turning it into money

The final step converts scale into economic impact. And the key here is that the rep doesn’t do the math — they ask the questions that lead the buyer to do it. When the buyer arrives at the number through their own reasoning, the number belongs to them. When the rep calculates it and presents it, the buyer looks for reasons why that number might be wrong.

Question 7

“If we solved this, how much time would the team recover each week?”

Question 8

“With that recovered time, how many more deals could a rep manage this quarter?”

Question 9

“How would you frame that impact in terms of the number you need to hit this quarter?”

At the end of Monetize, the buyer has a number they calculated themselves, backed by data they provided themselves, structured in a way they can present internally. The rep just built the path. That’s exactly the kind of business case that survives the internal approval process.

The job isn’t to bring the ROI to the call. It’s to help the buyer discover it.

Why this shouldn’t depend on the rep’s memory

Surface-Size-Monetize works. It also requires the rep to remember to run it on every call, not jump to the product before it’s time, and have the discipline not to move forward without closing each phase. In practice, that level of consistency is hard to maintain. Reps push toward the demo. Calls get derailed. The “pain” ends up as a vague sentence in the CRM notes.

And nobody knows until the deal falls apart weeks later, with no business case to hold it through the buyer’s internal approval process.

Performy runs this audit automatically over 100% of calls — not just the deals someone chose to review this week. It detects which phase of discovery each conversation is in, whether the rep went through Surface before moving to Size, whether there’s a concrete impact number or just an unquantified complaint. The manager sees where the pattern breaks without having to be on every call, and can act before the deal is lost.
