Five minutes is the best number in lead response. Tomorrow morning is the worst. If you want a straight answer to how quickly you should respond to leads, call within five minutes when you can, treat one hour as the outer limit during business hours, and never let an inquiry sleep overnight.
Those are targets, not promises. The research behind them is older than we’d like, and it measured something narrower than a sale. Here is what it found, what it didn’t, and how a small business without a salesperson can still hit the targets.
Why speed matters after you’ve paid for the inquiry
By the time a form arrives, the expensive part is done. The search work, the ad or the referral did its job, and a person with a problem reached out.
Take a garage door company in Newtown. A spring snaps on a Tuesday afternoon, the owner of the house fills out three contact forms from the couch, and each lands in a shared inbox. One company calls in ten minutes. The others reply the next morning, by which point the door has an appointment.
The standard reference is a 2011 article in Harvard Business Review, “The Short Life of Online Sales Leads”. The authors studied leads at U.S. consumer and business-to-business companies. Firms that tried to reach a lead within an hour were nearly seven times as likely to have a meaningful conversation with a decision maker as firms that tried even an hour later. We haven’t found a newer study that replaces it.
What the average reply looks like
Slower than most owners would guess. For that same article, the authors sent test inquiries to 2,241 U.S. companies and timed the replies. Among those that answered within 30 days, the average was 42 hours. Some replied within the hour. Some took more than a day. Some never replied.
Phone calls have newer numbers. Invoca’s Home Services Lead Conversion Benchmarks Report, published in July 2026, found that 52% of calls to home services businesses were answered by a person. Leave out calls of 15 seconds or less, which removes misdials and quick hang-ups, and the figure is 65%. That is Invoca’s own platform data from one industry, so we wouldn’t treat it as a number for every business. It does say that a good share of calls never reach anyone.
How quickly should you respond to leads, in practice
The most quoted figure comes from a study InsideSales ran with Dr. James Oldroyd of MIT, first presented in October 2007. InsideSales’ own summary says that calling within 5 minutes, compared with waiting 30 minutes, raised the odds of making contact by 100 times and the odds of qualifying the lead by 21 times.
Read that with four cautions. It is old, and so is the HBR work. Both looked at calls to people who had filled out a web form, not at local trades or clinics. In HBR, “qualified” meant a real conversation with the person who decides, not a sale. And the 2007 study came from a company that sells sales software.
What the studies agree on is direction. The sooner the first attempt, the better the odds of a conversation. They can’t tell you what a faster reply is worth to your business, and we won’t pretend to.
Urgency changes the target. A homeowner with water coming through a ceiling will keep calling until a person picks up. Someone planning a patio may compare companies over several days. They will still remember who answered first.
None of this means sitting beside the phone. It means having a system.
Where small businesses lose them
It’s rarely laziness. Everyone is out doing the work the business gets paid for, and each person assumes someone else replied. These are the questions we’d ask on a first call. Who answers the phone when the office manager is at lunch? Who checks the inbox that the website form feeds? What happens to a form that arrives at eight on a Friday evening?
If the answer to any of them is “whoever notices,” that’s the gap. It costs the most when you’re paying for local SEO or ads to bring inquiries in, and it is a big part of knowing whether your marketing is working.
Three fixes that don’t need a new hire
Give every channel one owner and one backup. Phone, form inbox, texts, Google Business Profile messages. Write the names down. This usually costs nothing and it fixes more than software does.
Let automation acknowledge the inquiry. A CRM is just a system that keeps track of the people who contact you. With marketing automation, a form can trigger an instant text or email and alert whoever owns that channel. Think of a fence company in Warrington where a homeowner submits a request at eight on a Friday night. The reply confirms the request and says someone will call Monday at 8 a.m. Monday starts with a call list instead of a mystery.
That reply is an acknowledgment. It can’t quote a job, so a person still has to call.
Text back missed calls. When a call goes unanswered, an automatic text such as “Sorry we missed your call. How can we help?” can go out right away. Call tracking also shows how many calls you missed and when, which tells you more than anyone’s benchmark. Automatic texts to customers fall under texting consent rules. Prepare your wording and opt-out process, then have your lawyer confirm they meet the requirements before you switch it on.
Faster replies fix one problem, not all of them. Visibility plus a faster response is the short version of lead generation, with one condition: the inquiries have to be for work you want. Quick replies won’t fix messages about jobs you don’t do, and we can’t promise that replying sooner produces a set number of customers. What it does is remove one common reason that good inquiries get lost.
Your part is the decisions only you can make: who owns each channel, what hours you can cover, and which inquiries turned into customers. Tell us those, and the rest of the setup is mostly mechanical.
Time your own reply tonight
Here’s the one job for this week. Tonight, after hours, fill out your own website’s contact form from your phone, then watch the clock. Write down when the acknowledgment arrives and when a person responds. It takes about ten minutes and costs nothing, and most owners learn something from it.
Send us what you find, plus how inquiries reach you now and who handles them. We’ll tell you what we’d fix first and why. Your first consultation is free. Send us a message or call (215) 368-8900.
