Free Discovery Call or Paid Diagnostic? Decide What You’re Offering

A prospective client asks you to “take a quick look” before deciding whether to work together. Sometimes that is a sensible fit check. Sometimes the quick look requires interviews, analysis and recommendations that are already the consulting work.

Decide what you are offering before the calendar invitation goes out.

Give each conversation a purpose

A discovery conversation helps both sides decide whether there is a relevant assignment. It can cover the goal, the current situation, constraints and the next decision.

A paid diagnostic produces something the client can use: an assessment, a prioritised plan or a specific recommendation based on agreed evidence. Its value should stand on its own rather than depend on buying a larger project.

Do not charge merely because a conversation takes time. Equally, you do not need to deliver the solution free to establish that you understand the problem.

Draw the boundary in plain language

Fit conversation Paid diagnostic
Clarify what the client wants to change Examine an agreed part of the business
Identify whether your service is relevant Analyse supplied evidence and selected interviews
Explain how an assignment could work Deliver a defined assessment or recommendation
Agree whether to proceed Review the deliverable against the agreed scope

Huthwaite’s SPIN methodology separates investigating needs from demonstrating capability. That distinction is useful here: ask enough to understand the assignment without pretending that a preliminary conversation is a completed diagnosis.

Make the diagnostic tangible

Here is a fictional scope for a small service company.

Question: Why do incoming website enquiries reach different team members without a clear owner?

Inputs: A sample of recent enquiry records, the current routing rules and interviews with the service manager and two colleagues.

Work: Trace the sample through the current process and identify where ownership becomes unclear.

Deliverable: A short findings note, a proposed assignment rule and a review meeting.

Outside scope: Rebuilding the CRM, rewriting website forms and managing the service team.

Next decision: Adopt the recommendation, commission an implementation or keep the current arrangement.

The diagnostic does not promise a percentage improvement. It gives the buyer a specific piece of work to accept or decline.

Explain the choice without pressure

You might say: “We can use a short call to check whether the enquiry-routing issue fits our work. If you want us to analyse the records and recommend a new process, I’ll scope that as a paid diagnostic.”

That makes the distinction understandable. Avoid disguising a sales call as a free audit with a promised report you have not defined.

Offer the smallest useful next step

If one answer would establish fit, ask it. If the buyer already understands the scope and wants a quote, do not insist on another call. If meaningful analysis is required, describe the deliverable and fee before doing it.

The consulting account-planning guide can help organise earlier conversations. Once an actual assignment appears, let its requirements determine whether the next step is discovery, a diagnostic or a direct proposal.
