Consultative selling: diagnose before you prescribe.

The short answer

Consultative selling means you diagnose the buyer's problem before you propose anything, the way a good doctor examines before writing a prescription. The buyer talks most of the time. You ask what is broken, what it costs and why now. You only present when you can name the problem better than they can.

What it looks like in a meeting

A transactional seller opens with the slide deck. A consultative seller opens with an agreement on how the meeting will run, then asks about the problem and keeps asking until the cost is clear.

For an example 40 person construction firm, that might sound like this:

  1. Where does a project usually go wrong: the estimate, the subcontractors, or the final inspection?
  2. How many project decisions still go through you as CEO?
  3. What did the last project that ran late cost you?
  4. Who else needs a say before you decide?

None of those questions mention your service. All of them tell you whether you have one worth selling to this buyer.

The three layers of a problem

Most people stop at the first layer. The deal is in the third.

  • The surface problem. “Our projects run late.”
  • The business cost. “Each late project costs us around $40,000 in penalties and overtime.”
  • The personal cost. “I spend my weekends fixing schedules instead of with my kids.”

These are pain questions. You move down by asking for an example, then for the cost, then for what it means to the person in front of you.

Where consultative selling goes wrong

  • Questions as a ritual. Asking five questions and then delivering the same pitch anyway. The buyer notices.
  • No agreement up front. Without one, the buyer decides what the meeting is for, and it is usually “send me a proposal”.
  • Never presenting. Diagnosis is not the goal. A clear recommendation is. If you have found the pain and the cost, say what you would do.

Consultative selling or Challenger?

They are not rivals. Consultative selling is the principle. The Challenger Sale adds that you should bring an insight the buyer has not seen. Allin adds structure and the right to say no. Allin Sales Brain is built on Tobias Ahlin's own method, and borrows a Challenger insight when the buyer does not yet know they have a problem.

How Allin uses it

Tell Allin Sales Brain who you are meeting and it writes discovery questions for that buyer, not a generic list. After the call, it reviews your notes and tells you which layer of the problem you reached and what to ask next time.

Questions

Short answers.

What is consultative selling?

A way of selling where you diagnose the buyer's problem through questions before you recommend anything. The recommendation is built from what you learned, not from your standard pitch.

Who came up with consultative selling?

Mack Hanan described it in his 1970 book Consultative Selling. The idea has since become the base of most modern B2B methods, including SPIN Selling and the Challenger Sale.

What makes consultative selling work in practice?

Structure. Agree the goal of every meeting up front, ask pain questions before you present, and keep permission to walk away. Consultative selling is the principle; those habits are how you enforce it.

How many questions should I ask in a discovery call?

Enough that the buyer talks for at least two thirds of the call. In practice that is four or five good questions with follow ups, not twenty from a list.
