How fast should a service business respond to a new lead?

Most service businesses lose more jobs to slow follow-up than to bad marketing. The lead came in, someone paid for it in ad spend or time, and then it sat. This guide covers what the research says about response time, how to measure yours, how to cover the hours when nobody is at a desk, and what to say on the first call and text.

The best-known study is “The Short Life of Online Sales Leads,” published in Harvard Business Review in March 2011 by James Oldroyd, Kristina McElheran and David Elkington¹. It has two parts.

First, the authors audited 2,241 US companies by sending each a web-generated test lead and timing the reply. 37% responded within an hour, 16% within one to 24 hours, 24% took more than 24 hours, and 23% never responded at all. Among companies that responded within 30 days, the average response time was 42 hours¹.

Second, they looked at 1.25 million sales leads received by 29 B2C and 13 B2B companies. Firms that tried to contact a potential customer within an hour of the query were nearly seven times as likely to qualify the lead (defined as having a meaningful conversation with a key decision maker) as firms that tried even an hour later, and more than 60 times as likely as firms that waited 24 hours or longer¹.

An earlier and widely cited source is the Lead Response Management study, presented by Oldroyd and InsideSales.com in October 2007². The summary page reports three years of data from six companies, more than 15,000 leads and more than 100,000 call attempts. Its headline finding: the odds of contacting a lead called within 5 minutes versus 30 minutes “drop 100 times,” and the odds of qualifying it drop 21 times². Treat this one with care. It was published by a software vendor that sells lead response tools, the summary does not show the statistical method, the companies were not home service firms, and “contact” and “qualify” were defined differently at each company². It points the same direction as the HBR work, but the 100x number is not something to quote as a law of nature.

What both studies support is the shape of the curve: the value of a fresh inquiry falls fast, and the steepest drop is in the first hour.

Three reasons, the last of which is specific to how service businesses buy leads.

1. The need is often urgent. A leaking water heater or a dead AC unit is a problem the customer wants solved today. The first company that answers and gives a time window usually gets the job.
2. Customers contact more than one company. Someone who fills out a form on your site may have called two competitors from the Map Pack while waiting.
3. Shared leads are a race by design. When a marketplace sends the same request to several pros, the first useful conversation has a large advantage. See exclusive vs. shared leads for how that changes what a lead is worth.

There is also a direct ranking effect on one channel. Google lists “your responsiveness to customer inquiries and requests” as a Local Services Ads ranking factor and says “missed calls may negatively affect your responsiveness.” Average response time also appears in its profile quality factors³. Slow answers cost you the lead in front of you and the next ones.

You cannot fix what you do not time. Track two numbers every week.

The targets are a common rule of thumb drawn from the research above, not a sourced benchmark. Set your own baseline first. Many owners are surprised by their real answer rate once a call tracking report shows every ring, not just the calls someone remembers. Lead tracking and attribution covers how to set that up.

All inputs below are illustrative. Swap in your own numbers.

A plumbing company gets 300 inbound calls a month from all sources. It answers 75% live. The other 25%, or 75 calls, go to voicemail.

• Assume half of the missed callers never call back and hire someone else: 75 x 0.5 = 37.5 lost callers a month.
• Assume the company books 60% of callers it actually speaks with, at an average ticket of $450.
• Value of a reached caller: 0.60 x $450 = $270.
• Lost revenue: 37.5 x $270 = $10,125 a month, or about $121,500 a year.

Now compare a fix. Suppose an answering service or a part-time dispatcher costs $1,200 a month (illustrative) and raises the live answer rate to 95%. Missed calls fall from 75 to 15. Using the same assumptions, lost callers fall from 37.5 to 7.5, a gain of 30 callers, worth 30 x $270 = $8,100 a month in revenue. At a 40% gross margin (illustrative), that is $3,240 of gross profit for $1,200 of cost.

The point is not the exact numbers. It is that answer rate is often the cheapest lead source a business has, because the leads are already paid for.

Leads do not stop at 5 p.m. Google itself says that enabling message and booking leads in Local Services Ads helps “especially during nights and weekends when you can’t answer the phone”³. Here are the usual options and their trade-offs.

Get quotes before you buy. Pricing models differ (per minute, per call, flat monthly), and the cheapest per-minute plan can be the most expensive if agents keep callers on the line.

The first call has one job: book the next step. A simple structure most operators can train in an afternoon:

1. Greet with the company name and your name. “Thanks for calling Smith Plumbing, this is Dana.”
2. Confirm the request in their words. “You said the water heater is leaking from the bottom. Is water still coming out right now?”
3. Qualify in three questions. Address and service area, urgency, and whether they own the property or need the owner’s approval.
4. Offer two specific times. “I can have a tech there between 2 and 4 today, or first thing tomorrow between 8 and 10. Which works better?”
5. Confirm and set expectations. Repeat the window, any trip or diagnostic fee, and that they will get a text when the tech is on the way.

For form leads, open with the reason you are calling: “Hi, this is Dana from Smith Plumbing. You just sent us a request about your water heater. Do you have two minutes?”

If a form lead does not answer, send a text right away. Keep it short, specific and about their request:

For a missed call:

Texts are regulated. The FCC’s Telephone Consumer Protection Act rules cover text messages as well as voice calls, and they require prior express written consent for telemarketing calls and texts sent with an autodialer or prerecorded voice to a wireless number⁴. Federal rules also bar telephone solicitations to residential subscribers before 8 a.m. or after 9 p.m. local time⁴. A reply that only answers someone’s own request is very different from a promotional blast, but the line can blur, so keep follow-up texts about the job they asked about and leave sales offers out.

State laws can be stricter. Florida’s Telephone Solicitation Act requires prior express written consent for unsolicited sales calls and texts that involve “an automated system for the selection and dialing of telephone numbers”⁵. Oklahoma’s 2022 law has a similar consent rule, limits solicitation calls to 8 a.m. through 8 p.m., and caps them at three per 24 hours on the same subject⁶. Both allow private lawsuits with $500 minimum damages per violation⁵⁶.

Honor every opt-out. Under current FCC rules, a reply of “stop,” “quit,” “end,” “revoke,” “opt out,” “cancel” or “unsubscribe” is a valid revocation, and requests must be honored within ten business days⁴. Put consent language on your web forms and keep records. The full rules, including a September 2026 FCC change to how opt-outs work, are in TCPA and lead consent.

• Checking the lead inbox twice a day. HBR named batch retrieval of leads from CRM systems as one cause of slow response¹. Push every lead to a phone as an alert.
• Round-robin rules that wait for the “right” person. HBR also flagged lead distribution rules based on geography and fairness¹. A fast answer from anyone beats a slow one from the ideal rep.
• Voicemail as the after-hours plan. Many operators find that most callers hang up rather than leave a message. Use text-back at the least.
• Calling once. One attempt is not follow-up. Build a short sequence of calls and texts over the first two days.
• Not timing it. Without timestamps, every team believes it is fast.
• Texting promotions to people who only asked for a quote. That shifts a service reply toward telemarketing, with the consent rules that come with it⁴.

• Aim for first contact within 5 minutes, with one hour as the outer limit. The HBR research found leads contacted within an hour were nearly seven times as likely to be qualified¹.
• Measure answer rate and form response time every week. Missed calls are leads you already paid for.
• Cover nights and weekends with a real plan: on-call rotation, answering service, online booking, or text-back, matched to whether your work is emergency or planned.
• Use a short script whose only goal is to book the next step with two specific time options.
• Keep follow-up texts about the customer’s request, include an opt-out, honor it fast, and check Florida and Oklahoma rules if you text customers there.
