GAP Selling

Diagnose the gap between current and future state.

The gap that matters

Popularized by Keenan in his 2018 book, GAP Selling reframes sales as problem-centric rather than solution-centric. The seller's job is to diagnose the difference between the buyer's current state andfuture state — and quantify the gap between them. That gap becomes the deal.

Current State vs. Future State

• Current State: how things work today (people, process, tech), and the measurable problems that come with it.
• Future State: how things should work, what "solved" looks like, and the measurable outcomes.
• The GAP: the delta between the two — expressed in dollars, hours, risk, or growth.

Root cause discovery

Buyers describe symptoms. GAP Selling forces you to diagnose root causes before recommending a solution. The classic "5 whys" applies:

Buyer: "Our forecast is always wrong."
You: "Why?"
Buyer: "Because reps update the CRM the day before the meeting."
You: "Why?"
Buyer: "Because updating it is a chore."
You: "Why?"
Buyer: "Fields don't auto-populate; reps have to type everything."

Now you're solving a real problem, not a stated one.

Making the gap tangible

Once you've named the gap, put a number on it: "You're losing ~$1.2M in misforecasted deals per quarter" or "your reps spend 6 hours a week on admin — that's $180k in fully-loaded labor annually." Numbers turn conversations into decisions.
