How to Get More Customers Without Wasting Money

Ask small business owners what holds them back and the most common answer is customers. In the Federal Reserve's survey of small employers, 57% named reaching customers and growing sales as a top operational challenge, more than any other. ^[1]

The usual response is to buy more attention: another ad, another agency, another directory. Sometimes that is right. But the research points somewhere less obvious and much cheaper first. Many businesses are losing the customers they already attract: leads that wait days for a reply, profiles that look abandoned, happy customers who are never asked to come back or send a friend. Fixing those leaks costs time, not ad money, and it makes every dollar spent on advertising later work harder.

This paper sets out what the evidence says about winning customers, where small businesses most often waste money, the Groundwork Customer Ladder for deciding what to spend on first, and a 30-day plan.

What does the research say?

Speed wins the lead

In research published in Harvard Business Review, James Oldroyd, Kristina McElheran and David Elkington audited 2,241 U.S. companies by sending each a web inquiry. Only 37% responded within an hour, 23% never responded at all, and the average response among those that did reply within 30 days was 42 hours. A separate analysis of 1.25 million leads found that firms contacting a lead within an hour were nearly seven times as likely to qualify it as firms that waited even one hour longer, and more than 60 times as likely as firms that waited 24 hours or more. ^[2]

The lesson for a small business is blunt: a lead that waits until tomorrow is often a lead someone else already answered.

Customers check you before they call

BrightLocal's 2026 survey of 1,002 U.S. adults found that 97% read reviews of local businesses. 74% only consider reviews from the past three months, 47% will not use a business with fewer than 20 reviews, and 68% require at least four stars. 89% expect owners to respond to reviews, and 80% are more likely to use a business that responds to all of them. ^[3]

Google reports that customers are 2.7 times more likely to consider a business reputable, and 70% more likely to visit, when they find a complete Business Profile on Search and Maps. ^[4] Those are Google's own figures about its own product, so treat them as direction rather than proof, but the direction matches the survey data: a sparse, stale profile turns away customers the business never knew it had.

Ratings move revenue

Michael Luca of Harvard Business School studied every restaurant in Seattle from 2003 to 2009 and found that a one-star increase in Yelp rating led to a 5% to 9% increase in revenue. The effect was driven by independent restaurants; chain restaurants, which customers already know, were not affected. ^[5] Restaurants are one industry, but the mechanism fits any local business without a famous brand: when customers cannot judge you any other way, they judge you by what other customers say.

Referred customers are worth more

Philipp Schmitt, Bernd Skiera and Christophe Van den Bulte tracked about 10,000 customers of a German bank for almost three years. Customers who came through referrals stayed longer and were worth more on average than similar customers who were not referred. ^[6] Referrals do not just cost less to win; they tend to stay.

Keeping customers pays

Writing for Bain & Company, Fred Reichheld and Christine Detrick report that in financial services a 5% increase in customer retention produced more than a 25% increase in profit, and that the pattern holds across a wide range of businesses. ^[7] The exact figure will differ in your business. The direction will not: a customer you keep does not have to be won again.

Some advertising does nothing

In a large field experiment at eBay, Thomas Blake, Chris Nosko and Steven Tadelis found that paid search ads on eBay's own brand name had no measurable short-term benefit, because people searching for the brand were going to find it anyway. On non-brand search ads, new and infrequent customers were influenced, but frequent customers, who would have bought anyway, accounted for most of the ad spending, and average returns were negative. ^[8] eBay is a giant, not a corner shop, but the warning applies to any size: an ad that reaches people who were already coming is money spent for nothing.

What Groundwork's own research adds

Groundwork maintains internal judgment models built from a structured review of more than 1,500 investor-pitch cases, a knowledge base of Harvard Business School and Harvard Business Review research, and a microbusiness knowledge base drawn from government and academic sources. ^[9] Four lessons from them apply directly to winning customers.

1. Know what a customer costs and is worth before you scale spending. Across the pitch cases, the recurring warning sign was an owner who could not say what a customer costs to win, what one is worth, or whether sales came from a repeatable source rather than a one-time spike. Our working rule: establish those numbers before increasing ad spend. The U.S. Small Business Administration gives owners the same advice in plainer terms: compare your marketing and sales costs with the revenue they bring in, and keep one consistent way of measuring, because some tactics are hard to measure. ^[10]

2. Diagnose before you buy leads. When an owner says "we need more customers," the cause is one of three things: too few inquiries, too few inquiries turning into sales, or too few customers coming back. Each has a different fix, and only the first is solved by advertising. A business with an open calendar has a demand problem; a business that is fully booked does not need more ads.

3. Not every customer is worth winning. Robert Kaplan of Harvard Business School shows that customer satisfaction, retention and sales growth can all rise while a business loses money, when the cost of serving some customers exceeds what they pay. ^[11] Frank Cespedes, also of Harvard Business School, warns that selling to everyone fragments a small team's time and resources; the better path is choosing the customers who benefit most from what you do. ^[12] Michael Porter's classic argument in Harvard Business Review makes the same point at the level of strategy: a clear position requires deciding what not to do. ^[13]

4. Choose your fight. Groundwork's strategy method draws on Sun Tzu's The Art of War. Two lines fit marketing exactly. "If you know the enemy and know yourself, you need not fear the result of a hundred battles": check what your competitors offer, charge and are reviewed for before you spend. And "the way is to avoid what is strong and to strike at what is weak": compete for the customers and services where you are strongest and rivals are thin, not where the biggest competitor spends most. ^[14] One caution from our own framework: customers are never the enemy, and many local competitors make better referral partners than rivals. The plumber who does not do water heaters can send you those jobs.

Groundwork's assessment: The cheapest new customers are usually the ones a business is already losing. Fix response speed, credibility, retention and referrals first; then buy attention, and measure it.

The Groundwork Customer Ladder

Climb in order. Each rung is cheaper than the next and makes the rungs above it pay better.

Most small businesses start at rung 5. That is why so much marketing money disappears.

Rung 1: Answer fast

Set a rule: every call, form and message gets a human reply within one hour during business hours. If you cannot answer the phone while working, use a short text-back message and call back at the next break. Put your hours and a realistic reply time on your website and profile.

Keep a simple inquiry log: name, service requested, date, how they found you, estimated value, next step and outcome. A spreadsheet is enough. Within a month it will show whether your problem is too few inquiries or too few inquiries becoming customers, which is the difference between an advertising problem and a sales problem.

Rung 2: Look credible

Start with your website. A visitor should be able to answer four questions in a few seconds: what do you do, for whom, why choose you, and how do I reach you? Say it in plain words. "We deliver innovative, customer-centric property solutions" tells a customer nothing; "Residential and commercial cleaning in [your city]" tells them everything. Put the phone number and a contact or booking button where no one has to look for it.

Then complete every section of your Google Business Profile: services, hours, photos, description, and accurate categories. ^[4] Make reviews a routine, not a campaign: make the ask part of finishing every job, the same day, with a direct link. Reply to every review, good and bad, in your own words; customers notice templated replies. ^[3]

Know the review rules. The Federal Trade Commission's rule on consumer reviews took effect October 21, 2024. Businesses may not write, buy or sell fake reviews, and may not offer anything for a review on the condition that it is positive. Employees and family members who review the business must clearly disclose the relationship, and threatening or falsely accusing reviewers to get a review removed is prohibited. The rule does not require you to ask anyone for a review, and no one is obliged to chase the customer who stormed out. What the FTC warns against is screening: asking only the customers you expect to be happy, in a way that leaves the public a skewed picture. ^[15] Google's policies are stricter. They prohibit offering incentives for reviews and selectively soliciting positive ones, and Google can remove reviews it believes were gathered that way. ^[4] The practical habit: make the ask a normal part of finishing a job, not a filter.

Rung 3: Keep customers

Most businesses lose customers quietly, without ever knowing why. Call or message customers who stopped buying and ask. Set one simple follow-up after every sale: a thank-you, a check-in, a reminder when the next service is due. Our Bottleneck Finder flags "the one-time customer" when repeat business is the weak point.

Rung 4: Ask for referrals

Happy customers rarely refer unless asked. Ask at the moment of greatest satisfaction, usually right after the job is done well, and make it easy: "If you know anyone who needs this, here is a card," or a link they can forward. A small thank-you for a referral that becomes a customer is reasonable; check any industry rules that apply to you.

Referrals also come from other businesses. List five businesses that serve the same customers you do but do not compete with you: a cleaning company and the local real estate agents and property managers, a bookkeeper and the web designers and insurance agents who serve small firms. Learn what they offer, then introduce yourself professionally with a clear description of who you help. Good referral partners send business both ways, and they cost nothing to run once the relationship exists.

Rung 5: Buy attention, carefully

Paid ads can work, especially for reaching people who have never heard of you. Three rules keep them from wasting money:

1. Do not pay for people already looking for you by name. Ads on your own business name often reach customers who would have clicked your free listing anyway. ^[8]
2. Test small, with an end date. One channel, one offer, one type of customer, a fixed budget, four to eight weeks. If a $600 budget is available, start with a test of a quarter of it.
3. Count customers, not clicks. Ask every new customer "How did you hear about us?" and write it down. A channel is working only if it brings paying customers for less than they are worth.

A platform report can look impressive and still lose money. Suppose a $300 campaign shows 12,000 impressions, 240 clicks, 18 inquiries and 3 paying customers. The only number that pays the bills is the last one: $100 per customer. If a test produces inquiries but few customers, ask why before spending more. Were the inquiries outside your service area? Looking for a lower price than you charge? Unclear on what you offer? Left waiting for a reply? Each answer points to a fix that more ad money would not provide.

Know three numbers

You do not need marketing software to make good decisions. You need three numbers:

Here is the arithmetic for one job. A pressure-washing business charges $250 to clean a driveway. Labor costs $75, supplies $20 and fuel and job expenses $15, leaving $140 to cover advertising, overhead and profit. If winning that customer costs $100, only $40 is left for everything else. If it costs $150, the job loses money before overhead. Repeat business could change the picture, but do not assume it without evidence from your own records. (These figures are illustrations, not industry averages.)

If a customer is worth $300 in profit over their time with you and an ad channel costs $400 per new customer, the channel loses money no matter how busy it makes you feel.

Where small businesses waste money

• Ads before answers. Paying for leads that wait a day for a reply. ^[2]
• Ads on your own name. Paying for people who were already looking for you. ^[8]
• More leads when the close rate is low. If most inquiries do not buy, fix the quote, the follow-up or the price first.
• Long contracts without tracking. Agency or directory contracts with no count of the paying customers they bring.
• Neglected profiles and reviews. Spending on ads that send people to a stale profile with few recent reviews. ^[3]
• Chasing new customers while old ones leave. Every lost customer has to be replaced before the business grows. ^[7]

Example: one business, two marketing plans

This is a hypothetical example. The business and figures are illustrations, not data.

A residential cleaning company spends $1,000 a month on ads and feels it is not getting enough customers.

Ad spending went down. The number of inquiries that turned into customers is what the owner should now watch, and the log will show which channel deserves the next dollar.

A 30-day plan

The Groundwork Customer Checklist

Groundwork's final assessment

Most small businesses do not have a customer problem so much as a leak problem. Inquiries wait too long, profiles look neglected, customers drift away unasked, and referrals never happen because no one asks. Those leaks are cheap to fix and the evidence behind fixing them is strong: speed wins leads, reviews and complete profiles earn trust, referred and retained customers are worth more. Advertising earns its place after that, aimed at people who would not find you otherwise, and measured in customers, not clicks.

Put Groundwork to work for your business

Not sure where your customers are leaking? Groundwork's Advertising Checkup ($200) reviews where your money goes and includes a free directory listings check; our Google Business Profile Cleanup ($150) sets up your profile properly; and our Competition Checkup ($200) shows what customers see when they compare you with competitors. Every Groundwork project is fixed-price.

Anticipated Questions

I'm on a job site all day. I can't answer every inquiry within an hour.

Few owners can. The practical options are a short automatic text-back message that promises a call at a set time, returning calls in batches at planned breaks, or a part-time answering service. Each costs something; compare that cost with the value of the leads that go cold today.

I'm new. I have no reviews and no past customers to bring back.

Then your first customers are the plan. Serve them exceptionally, ask every one of them for a review and a referral, and complete your Google Business Profile from day one. The ladder still applies; rungs three and four simply start with your first ten customers.

My industry restricts referral rewards and testimonials.

Lawyers, financial advisers and some health professions have rules on referral payments and testimonials. Asking satisfied clients to recommend you, without paying for it, is usually still possible. Check your licensing body's rules first.

Isn't this just an argument against advertising?

No. It is an argument about order. Advertising wins when people who need you cannot find you any other way: a new business, a new service or a new area. Fix the leaks first so the ad money reaches a business that answers fast, looks credible and keeps the customers it wins.
