In short

Where does the 21x five-minute lead response statistic come from?

The 21x figure traces to a 2007 lead response study by InsideSales.com and Oldroyd. Read that study before you repeat it, including whose leads it measured and what it counted as success. A number measured at other businesses does not show what reply speed does for a small service business.

You may have read that calling a lead within five minutes makes you 21 times more likely to win them. Before you repeat it, read the original source. The claim on its own says little about where the number came from, what it counted, or who it was about. That matters if you run a small business and are deciding whether to drop everything each time an inquiry arrives.

Where does the 21x number come from?

It traces to a 2007 lead response study by InsideSales.com and Oldroyd. Other details people repeat about it, such as how many leads it covered, are worth checking in the study itself before you quote them.

When you read it, look for what the study counted as success. A good first sales conversation is not a sale.

Also check what the company behind it sold. A company with something to sell has a reason to say speed matters, even when its finding is true.

What should you check in the study?

When you read it, check these details:

Detail What to check in the original
Year When the data was collected
Who ran it Who ran it, and what they sold
Whose leads What kinds of companies the leads came from
How replies were made Phone calls, email, or both
Shortest window The fastest reply time it measured
What counted as success Reaching, qualifying, or winning the lead
What it did not count Whether sales won were counted

Three limits to look for:

  1. Whether it counted sales. A good first conversation is not a job won.
  2. Whose leads they were. Companies whose job is calling leads are not a plumber, a venue, or a design studio.
  3. When the calls were made. People now text, email, and book online. An older study cannot show whether a five-minute call works the same way today.

Does the 21x stat apply to a small service business?

Not as a number. A business with two people and a full day of work often cannot promise a reply in five minutes, whatever the study found. The choice it faces is more often an hour against tomorrow morning, and a figure about five minutes says little about that.

There is another catch. A sales team that calls back in five minutes is probably well run in other ways too. Some of the 21x may come from better teams, not only faster calls. Check whether a study separates the two before you lean on its number.

The direction still makes sense. Someone who just sent an inquiry is thinking about it now. An hour later, they may have called someone else. How much that matters depends on the job:

  • A burst pipe. The person needs help today and will call the next name on the list. A reply in minutes may decide who gets the job.
  • A wedding booked a year out. A reply the same day is polite and enough.
  • A website redesign. The buyer is comparing studios over days or weeks. A clear, useful reply matters more than a fast one.

So the real question is which inquiries need you now. In Qualiform, each lead's score puts it on one of five rules you set, from offering the soonest open times down to saying politely that it is not a fit. A fast reply also depends on hearing about the lead, so choose on the Routing tab who gets the lead email. The lead routing guide covers choosing those rules. For the other end, see how to reply kindly to inquiries that are not a fit.

How do you check whether speed matters for your inquiries?

Use your own numbers instead of someone else's average. For the next month, write down three things for every inquiry:

  1. How long you took to reply, in hours.
  2. What kind of job it was.
  3. Whether it became paid work.

Then read the list side by side. If the jobs you won were the ones you answered within the hour, speed matters for you, and you can see which kind of job it matters for. If fast and slow replies won at the same rate, a careful reply the same day is enough. The guide to qualifying leads from your contact form shows how to sort inquiries before you reply.

Common questions

Is the 21x statistic wrong?

It is not known to be wrong, but one number can be narrow. Check the original study for whose leads it measured, how replies were made, and what it counted as success. A figure from other companies does not show what a reply time does to sales at a small service business.

Does an email reply count as responding fast?

Check whether the study behind the 21x figure looked at email or text replies at all. If your customers prefer email, track your own reply times and which inquiries became paid work.
