Response time

How fast you have to reply to enquiries (and why)

Whoever replies first wins: 78% buy from the first provider to respond. Why five minutes decide the job and how your business can pull it off.

The honest answer is: faster than you are now. Almost every business underestimates how brutally response time decides between a deal and no deal. It is not about politeness, it is about maths. Someone who sends an enquiry is at their hottest in that moment and often comparing several providers. The first to respond well gets the conversation. Everyone else argues against a decision already made.

The 5-minute rule explained

The best-known figure comes from a study out of MIT that analysed more than 15,000 leads and over 100,000 call attempts. The result is clear: respond within five minutes instead of thirty and your odds of reaching the lead at all are roughly a hundred times higher. Your odds of qualifying them into a real conversation are about twenty-one times higher.

The drop is not a gentle slope, it is a cliff. Between minute five and minute thirty, reachability already collapses, not because the lead is offended, but because they keep clicking, find the next provider and mentally move on. On top of that, surveys repeatedly cite figures around 78 percent of buyers closing with the first provider to respond. Being there first means you frequently win before the real competition begins.

What a late “I’ll get back to you” costs

If you think a callback the same day is enough, you are wrong. A Harvard Business Review audit of 2,241 companies found an average first response time of around 42 hours, and nearly a quarter of firms never replied at all. The same study shows: respond within an hour and you qualify leads about seven times more often than an hour later, and roughly sixty times more often than someone who lets a day pass.

So every “I’ll get back to you” is a promise with an expiry date. By the time you reply in the evening, the lead often already has two other quotes and may even have said yes. The good part: because so many businesses are so slow, you do not have to be perfect, only fast. Speed alone beats most of your competition.

Why a third of trade calls get lost

The phone is often the most important channel for trades and service businesses, and it is exactly where the most gets lost. Studies of small businesses show a significant share of incoming calls go unanswered, often a third or more. The reason is not ill will but daily life: you are on site, with a customer, both hands busy.

What stings is what happens next. The large majority of callers leave no voicemail, they simply dial the next number. Around 85 percent of those who hit voicemail never call back. A missed call is therefore almost always a lost job. How to catch missed calls anyway is in never lose an enquiry again.

How to reply instantly, even on site

The only way to hold the five-minute line reliably is to stop making the first response depend on you being present. An automatic first reply goes out the moment the enquiry arrives, around the clock, in your tone. It confirms, asks the key questions and keeps the lead warm until you take over.

The important part is that it does not feel like a machine. The point is not to pretend no system is involved, it is that the customer feels seen immediately. How to do that without becoming impersonal is in automating customer enquiries, and how the fast reply turns straight into a booking is in letting customers book online.

You hold the real conversation afterwards, just with someone you have not lost. How this fast first reply fits into the larger flow from enquiry to customer is in the guide to handling enquiries. What such a system takes over is in the services, and whether it is worth it for you we clarify in a free potential analysis.

FAQ

Frequently asked

How fast should I respond to an enquiry?
Within five minutes. An MIT study shows your odds of reaching a lead are a hundred times higher after five minutes than after thirty, and your odds of qualifying them twenty-one times higher. After an hour the edge is almost gone.
What does being first actually get me?
A lot. Surveys show a large share of buyers close with the first provider who gets back to them, figures around 78 percent are often cited. Responding first and well means you frequently win before the actual selling even begins.
How am I supposed to reply instantly when I am on site or in a meeting?
That is exactly what the automatic first reply is for. It goes out the moment the enquiry arrives, around the clock and in your tone, even when your hands are full. You hold the real conversation afterwards, just with someone you have not lost.
Is calling back the same day not enough?
Rarely. According to Harvard Business Review the average first response takes around 42 hours, and those who react within an hour qualify leads seven times more often. Call back in the evening and you often reach someone already with whoever was faster.
