The first five minutes: why response speed decides the sale

You can have the best filter in the world and still lose the customer: if a qualified lead lands and nobody calls within the first half hour, all the screening work goes to waste. Here is the evidence, and what it means for a local service business.

What the research found

The classic reference is the Lead Response Management Study (MIT with InsideSales). Two of its findings are uncomfortable reading:

• Making contact within the first five minutes makes you about 21 times more likely to qualify the lead than reaching out at thirty minutes.
• The odds of actually getting the person on the phone are roughly a hundred times higher in those first five minutes.
• Slipping from five minutes to ten already degrades the outcome sharply — the curve does not decay gently, it falls off.

Harvard Business Review published an analysis of roughly 15,000 leads and 100,000 call attempts showing the other side: the average company takes around 42 hours to respond, and about 23% of leads never get a response at all. The bar is so low that simply answering quickly remains a competitive advantage.

One widely quoted figure — that 78% buy from whoever replies first — circulates mainly in vendor publications, so treat it as a direction rather than a hard number. What every source agrees on is the order of magnitude: minutes, not hours.

Where those minutes go

It is almost never lack of interest. The alert lands in an inbox checked twice a day, or in a dashboard nobody has open. The lead is qualified, but it sits there.

That is why Quizanta pushes a qualified lead to WhatsApp the moment the quiz is completed: it arrives on the phone already in the person's hand, with the answers summarised. No dashboard to open, nothing to remember to check.

Making it work in practice

• Name who responds, and when. Without an owner, «respond fast» is an intention, not a process.
• Draft the first message as a template that uses two details from the quiz — it stops sounding generic and shows you actually read the answers.
• Outside working hours, reply with a clear expectation («I'll call tomorrow between 9 and 11») instead of going silent until the next day.
• Measure time-to-first-contact, not just lead count. It is the metric that moves closing rates most, and the one almost nobody records.

How this fits with screening

Speed and qualification solve different problems and need each other. Screening without speed leaves you with good leads gone cold; speed without screening means calling unsuitable people faster, which carries a concrete cost. What works is the boring combination: filter on the page, alert instantly.
