Before: research the answerable facts
Anything published, recorded in a previous conversation or captured on the enquiry form should be known in advance. Every basic fact you ask for during the call is a minute of buyer attention spent on something you could have found yourself.
Open: agree the purpose and the time
State plainly that the aim is to understand their situation and work out whether there is a fit, that a tailored demonstration would come afterwards if it makes sense, and confirm how long they have. This is also where you make it acceptable to conclude there is no fit, which removes a surprising amount of tension.
Middle: current process, problem, consequence
Ask how the work is handled today, then where it breaks down and how often, then what happens as a result. The consequence questions are the ones that matter and the ones most often skipped, because they are slower and less comfortable than moving to a solution.
Then: people, history and timing
Establish who else is affected and who would need to agree, what has been tried before and why it did not stick, and what is driving the timing. Prior attempts are particularly informative, since they tell you both how serious the problem is and which objections are already in the room.
Close: a specific, dated next step
End with a commitment that can be written in a calendar: a second meeting, an introduction, or a document by a named day. A warm ending with no date is the single most reliable predictor of a deal that quietly disappears.
A worked example of the sequence (illustrative)
A services business enquires about a CRM. Research shows a team of about a dozen and an enquiry form on the website. Current process: calls and WhatsApp messages come to two mobile numbers and are written into a shared sheet at the end of the day. Problem: on busy weeks, some never make it into the sheet. Consequence: the owner estimates a handful of enquiries a month go unanswered, and describes what a typical job is worth. People: the owner decides, the operations manager would run it day to day. History: they tried a spreadsheet with reminder columns, which lasted two months. Timing: they want it settled before their busy season. Next step: a thirty-minute working session, dated, with the operations manager present. Nothing was demonstrated, and the deal is now specific enough to sell into.
