01 · The Problem

The inquiry you paid for goes to whoever replied first

Most service businesses spend real money generating inbound inquiries. Paid channels, directories, referral programs, a website that took months. Then the inquiry arrives, and it waits.

It waits because whoever would answer it is with a client, on another call, or offline. By the time somebody picks it up, the prospect has already contacted two or three competitors and committed to one of them.

None of this appears in reporting. The inquiry was received. Somebody responded. It simply did not convert. The spend that generated it is gone, and no line item anywhere explains why.

88%
HVAC businesses that had already bought speed-to-lead software and still took more than five minutes to reply — across 132,188 campaigns analysed by Hatch in 2024.
63.5%
Businesses that never replied at all when RevenueHero submitted a request to 1,000 websites. Not slowly — never.
100×
The drop in the odds of reaching a lead at all between a five-minute callback and a thirty-minute one (Oldroyd, 2007).
21×
More likely to qualify a lead by replying in five minutes rather than thirty (Oldroyd, 2007).
35–50%
Share of deals won by whichever business responds first — a range, not a figure, which is why it sits on a slider below.
3 in 4
Hours in the week a nine-to-five business is closed. Inquiries do not observe opening times, and any arriving then wait by default. Arithmetic, not a study.

Why this problem stays invisible

Most operational problems announce themselves. A system goes down, a deadline slips, an invoice goes unpaid. You find out because something stops.

This one never stops anything. Inquiries keep arriving, the team keeps working, the numbers look broadly consistent month to month. The loss consists entirely of things that did not happen, which is why it is almost never quantified.

Your numbers, not ours

The calculator runs entirely in your browser. Nothing is transmitted, nothing is stored, and there is no form to complete.

02 · The Tool

Calculate your leak

Five inputs. Approximate figures are fine, the output is a range rather than an audit. Everything updates as you type.

Every new inbound contact. Web form, phone, referral, all channels.
What a typical customer is worth to you, in whichever currency you use.
Of the inquiries you actually speak to, how many convert.
Be honest, and account for evenings and weekends rather than your best day.
Research places this between 35% and 50%. Move it down for a more conservative figure.

How the number is derived

No hidden assumptions. The entire calculation is four steps:

  • Your response speed sets the share of inquiries where a competitor reached the prospect first
  • That share is multiplied by the proportion of deals won by the first responder
  • That gives lost inquiries, multiplied by your close rate to give lost engagements
  • Lost engagements multiplied by average value gives the figure

Both assumptions sit on sliders because they are estimates, not laws. Move them to the most conservative position you find credible and see whether the number still concerns you.

Now establish whether it is bad

A number in isolation means very little. The next section shows where your response speed sits against the market.

Read your number

Response speed falls into bands, and the band matters more than the exact minutes. Here is what each one means.

Response speedWhere that places youWhat it means for the inquiry
Under 5 minutesTop 7% of all businessesYou are almost always first. The prospect speaks to you before deciding to shop around.
Within an hourBetter than mostCompetitive on anything arriving in working hours. Evenings and weekends remain exposed.
Same dayRoughly averageYou reach prospects after they have spoken to someone else. You are arguing against a decision, not shaping one.
Next working dayBelow averageMost inquiries are committed elsewhere. You are working the remainder of your own spend.
Two days or moreBottom of the marketClose to the point where most inquiries have been committed elsewhere. The inquiry is effectively transferred to whoever responded.

Three factors that skew the figure

3 in 4
Out of hours is most of the week. A business open nine to five on weekdays is closed for roughly three quarters of the week's hours. If you only respond during those hours, the rest wait by default — however fast your team is at 11am.
They contacted competitors too. A prospect with an urgent problem typically contacts two or three businesses the same afternoon. Speed is not courtesy, it is the race.
0
Nothing records the loss. No system logs the inquiry answered too late. It becomes a lead that did not convert.

Sanity checks before you trust the figure

  • Audit one real evening. Look at what arrived after 6pm last Tuesday and when it was answered. Most operators are surprised.
  • Count the channels. If inquiries land in a shared inbox, a personal mobile and a web form, nobody owns all three, and the gaps are where the loss sits.
  • Ask who responded first. On your next won engagement, ask how many businesses the client contacted and who came back first. One question, and it tells you more than any report.

If the number is uncomfortable

The final section covers what closing the gap involves, how long it takes, and what it does not require.

04 · Closing The Gap

Closing the gap

The remedy is not additional headcount, and it is not another CRM nobody adopts. It is a single intake system that captures every inquiry and responds before the prospect moves on.

What gets built

One destination for every inquiry

Web form, phone, missed calls and referrals all feed a single system, so nothing depends on who happened to be watching.

A response inside five minutes

Automated acknowledgement and qualification the moment an inquiry lands, at 2pm or 2am, with nobody on duty.

Missed calls answered by message

An unanswered call triggers an immediate message that keeps the conversation open instead of losing it to voicemail.

A named owner for every inquiry

Routed to a person, with a task and reminder attached, so it cannot sit unclaimed in a shared inbox.

Booking and reminders

The prospect books directly into a live calendar and is reminded, which addresses the no-shows follow-up was meant to prevent.

A record of every one

Every inquiry tracked to booked or closed, so next quarter the leak is measured rather than estimated.

What it requires from you

Access to the systems you already run, and roughly an hour of somebody's time to explain how inquiries move through the business today. No change to how your team works, no new software for them to learn, no process to roll out.

A typical build takes about three weeks. Response times drop in the week it goes live, because acknowledgement is the first component switched on.

What this is not

  • Not lead generation. This concerns the inquiries you already pay for.
  • Not a chatbot attached to your website.
  • Not a rebuild of how your team operates.
  • Not a monthly platform subscription with nobody to configure it.

Where the figures come from Every benchmark on this page has been read at its original source, and the ones we could not verify have been removed rather than softened. The 21× qualification difference and the 100× contact difference between a five-minute and a thirty-minute reply come from Dr. James Oldroyd's Lead Response Management Study, presented in October 2007 — a study carried out with, and published by, InsideSales.com, which sold software to fix the problem it measured. We note that because it matters, and because the paper concedes its own causal explanation is guesswork. The 88% of HVAC businesses taking longer than five minutes comes from Hatch's analysis of 132,188 speed-to-lead campaigns run by its own customers in 2024 — businesses that had already bought follow-up software. The 63.5% who never replied comes from RevenueHero's own test of 1,000 websites, in a different sector, offered for scale rather than as a benchmark for yours. The 35–50% first-responder share is attributed to a Google and Corporate Executive Board white paper we have not been able to obtain, which is why it sits on a slider rather than being stated as fact. The three-quarters-of-the-week figure is arithmetic. Your own output is calculated entirely from the values you enter, in your browser, and is never transmitted or stored.
