How to keep customers coming back

The line that keeping 5% more customers lifts profits 25% to 95% was stated in 2000 for e-companies, with no method on the page, so do not budget around it. The step you can measure this week is the second visit: in Boulevard's 2023 platform data (vendor data), average salons turned 45% of first visits into a second appointment while the top tenth turned 70%, and the habit we would build first is booking the next visit before the customer walks out.

The 25% to 95% line: Stated in a 2000 summary about e-companies, with no method on the page (Bain)
First visit to second: 45% at average salons, 70% at the top tenth (Boulevard platform data, 2023, vendor)
Maintenance plans: 75% of 400 homeowners rated a twice-a-year HVAC agreement important to offer (ACHR News, 2023)
Calling past customers: For live calls to numbers on the Do Not Call registry, the past-buyer exemption runs 18 months from the last purchase, unless they ask you not to call
Clinic gifts: OIG safe threshold for Medicare or Medicaid patients: $15 per item and $75 per patient per year, never cash
Win-back email: Postal address and opt-out in every message; opt-outs honored within 10 business days (FTC)

This playbook covers the customers you already have, in the order you meet them, from the visit ending now to the ones who drifted away. It starts with two statistics you have probably heard, because both get used to justify spending nobody then measures.

What the famous retention numbers actually say

“Keep 5% more customers and profits rise 25% to 95%”

Follow the citations and the line comes apart into four different claims:

The 1990 Harvard Business Review article “Zero Defections” by Reichheld and Sasser (abstract via the ESCP library) reports that cutting the defection rate by 5% produced 85% more profit in one bank’s branch system, 50% more in an insurance brokerage and 30% more in an auto-service chain, and that MBNA’s profits rose 125% when it halved a 10% defection rate. Those are consulting case examples from large named companies, not a sample, and it is unclear whether 5% means percentage points or a relative cut.
Bain’s own summary of that 1990 article says companies can boost profits by almost 100% by retaining 5% more of their customers. A different number again.
The 25% to 95% range appears in the summary of Reichheld and Schefter’s July 2000 HBR article on e-loyalty, republished by Bain, where it is stated for e-companies: “By retaining a mere 5% more customers, e-companies can boost profits by 25-95%.” The page gives no method and no industry breakdown, and we could not establish whether the range appeared anywhere earlier.
The 2001 Bain brief that HBR links as the source for the 25% to 95% line says only that, in financial services, a 5% increase in retention produces more than a 25% increase in profit. The 95% is not in it.

None of these sources measured a salon, a clinic or a heating company.

“A new customer costs five times as much as keeping one”

HBR’s 2014 article on keeping the right customers gives acquisition as 5 to 25 times the cost of retention but names no study, saying it depends on “which study you believe” and the industry. Ipsos Loyalty researchers, in an excerpt from their 2005 book Loyalty Myths, said the earliest sources they found attribute the five-times claim to TARP research in the late 1980s, that its origin is hard to establish, and called it a myth.

Stop using either line to size a retention budget. Pull three figures from your own software instead: purchases per customer per year, the average ticket, and how long customers stay. That value is what tells you what a win-back offer can afford.

How often your kind of customer comes back

Know the natural rhythm of your trade before setting a target. These figures come from different populations, so use them as a sense check.

Business	What the source found	Caveat
Chiropractic	Adults who saw a chiropractor in the past 12 months reported 11 visits on average (Gallup, 2015)	Self-reported mean, commissioned by Palmer College
Massage	Consumers received 2.7 massages on average in the past 12 months (AMTA, 2025)	Unclear whether the base is massage users or all respondents
Salons	Average salons turn 45% of first visits into a second appointment and 39% into a third; the top tenth reach 70% and 57% (Boulevard via Salon Today, 2023)	Vendor data, 11M+ appointments on one platform
Restaurants	Up to 50% of order volume can come from the 7% of guests who visit more than once (Toast and Resy, 2026)	Vendor data

Zenoti’s 2025 benchmark figures (vendor data) say top-earning salons rebook clients within 24 hours at three times the average rate, with no definitions or sample given.

In the Boulevard data, the step from first visit to second is where most clients slip away. Booking that visit before the client leaves is how we would close the gap, a practice rather than a measured result.

Book the next visit before they leave

This is the cheapest fix here, because the customer is in front of you and already pleased. None of these steps has a measured effect behind it; they are what works at the front desk.

Write down the interval for each service

Put each service’s natural next date (a color, a massage series, a care plan, a quarterly pest treatment, a fall tune-up) on the service menu or job card, so everyone quotes the same answer. A provider’s different advice for one customer goes in that customer’s record.

Offer two times, never an open question

“Would you like to book again?” invites “I’ll call you.” Two specific times invite a choice.

At a salon front desk:

“Your color came out beautifully. To keep it this shade, most people come back in about six weeks. I have Tuesday the 14th at 5:30 or Thursday the 16th at 10. Which is easier?”

At a chiropractic or physical therapy checkout:

“Your plan has two more visits this month. I can do Monday at 7:40 before work or Wednesday at 12:15. Which should I hold?”

For quarterly pest or seasonal HVAC work, the office calls the week the visit is done:

“Hi, this is Dana from the office. Luis finished your treatment this morning, and your next one falls the week of March 9. Can I put you down for a morning that week?”

If they will not commit, ask how to remind them

Ask whether they want a reminder when they are due, by text or email, and record the answer and date in their file. A reminder someone asked for is a different message from a marketing offer, and the win-back section depends on knowing which permission you hold.

Count it every week

Track the share of visits that leave with the next one booked, per staff member. In our experience, when one provider’s customers rarely rebook, the question usually is not being asked.

Maintenance plans homeowners say they want

For recurring home services, a maintenance agreement is the rebooking habit written into a contract. The evidence below comes from HVAC surveys and does not show what plumbing, electrical or pest customers want.

In a Clear Seas Research survey reported by ACHR News in 2023, 72% of 100 responding HVAC contractors said they offer maintenance agreements, and 75% of 400 homeowners rated it important for an HVAC contractor to offer a twice-a-year service agreement. That is importance, not intent to buy. A separate homeowner survey for ACHR News in 2025 found 15% rated agreements “extremely” important, 24% “very” and 35% just “important”; if they bought one, 57% said they would want to spend about $100 a year, and they wanted discounts on parts (76%) and labor (80%) and priority service (77%). That article gives no sample size and does not name HVAC, though the context implies it.

On commercial work, 46% of over 1,000 contractors in ServiceTitan’s 2026 survey, reported by ACHR News, said more than half their commercial customers are on agreements, up from 42% in 2025 (vendor data).

Build the plan around those three asks

Two visits a year, booked by your office ahead of the heating and cooling seasons.
A stated discount on parts and on labor for repairs between visits.
Priority scheduling in plain words, such as members booked ahead of non-members the same day.
One written line on what the plan does not cover.
A renewal date in the record and a reminder before it.

Offer it on every visit, in the same words

From the technician, at the end of a tune-up or repair:

“You’re all set. Before I head out: we have a plan where we come twice a year, spring and fall, you get money off parts and labor if something breaks in between, and you go to the front of the line in a heat wave. Want me to leave the details, or have the office call you this week?”

Train the office to say it the same way, then track plans sold per eligible visit and plans renewed out of plans due.

Recognize your regulars

Restaurants, cafes, gyms and walk-in shops have no checkout calendar, so the work is knowing who came back.

Toast and Resy’s Regulars Report 2026 found that in Q1 2026 data (vendor data), guests in a loyalty program returned at nearly 30% against a 7% baseline; joiners may already have been likelier to return. In the same report’s survey of 1,500 US adults who dine out or order in at least twice a month, 48% said they value being remembered, against 22% for points.

Capture each guest’s name and contact, with consent recorded, through reservations, online ordering or a counter sign-up.
Brief the floor before service on who is booked and what they ordered last time.
Use names: “Welcome back, Ellis. The booth by the window again?”
In gyms and studios, flag members whose check-ins fall off and have a person reach out before they cancel.

This is not legal advice; confirm with counsel before you text, call or email anyone about an offer. The rules are stated as of October 3, 2026, and some are moving.

Define lapsed and scrub the list

A customer is lapsed when they have missed their natural return date by a clear margin: twice the usual interval at a salon, a skipped quarter for pest service, a missed season for a tune-up. Pull the list with each person’s last purchase date and last inquiry date, because those dates decide what you may do. Then:

Remove everyone who opted out of texts, email or calls in any tool, and push each opt-out to every other tool.
Check how each person gave their number. A number given to book an appointment is not signed agreement to marketing texts.
Flag anyone whose last purchase was more than 18 months ago, or whose only contact was an inquiry more than 3 months ago. If their number is on the national Do Not Call registry, they cannot get a sales call without signed written permission.

The rule for each channel

Email. The FTC’s CAN-SPAM compliance guide says the law covers every commercial email, including a message to former customers announcing a new product line. Each message needs a valid physical postal address and a clear opt-out, opt-outs must be honored within 10 business days, and penalties run up to $53,088 per violating email. Transactional and relationship messages are exempt from most provisions, read narrowly; a “we miss you” offer is commercial.

Texts. FCC rules require prior express written consent for autodialed texts that include an advertisement or constitute telemarketing (47 CFR 64.1200): a signed agreement, electronic signatures included, that names the number, authorizes the marketing messages and says signing is not a condition of purchase. After the Supreme Court’s 2021 Facebook v. Duguid decision, most CRM texting is probably not autodialing under federal law, but Florida, Oklahoma and Maryland have their own written-consent rules for automated sales calls, which Florida defines to include texts, so send win-back texts only to people who signed up for marketing texts. CTIA’s messaging guidelines add that a call to action such as a coupon code may make an informational text promotional.

Calls. A live sales call to a number on the Do Not Call registry is allowed under the established business relationship exemption only within 18 months of a purchase or 3 months of an inquiry or application, and the relationship ends when the person asks you not to call (47 CFR 64.1200). Do-not-call requests must be honored within a reasonable time not exceeding ten business days. Calling a cell phone with an artificial or prerecorded voice needs prior express consent under the TCPA, written consent for telemarketing, and FCC 24-17 confirms that AI and cloned voices count as an artificial voice.

Time of day. Federal rules bar telephone solicitations before 8 a.m. or after 9 p.m. local time; calls under an established business relationship fall outside that definition, but the FTC’s Telemarketing Sales Rule separately limits outbound telemarketing calls to the same window. Florida, Oklahoma and Maryland bar commercial solicitation calls before 8 a.m. or after 8 p.m. and more than three in 24 hours on the same subject. That window is verified for those three states only, not nationally; have counsel check each state you serve.

Opt-outs. Under the rule in force today, a reply of stop, quit, end, revoke, opt out, cancel or unsubscribe ends consent, other wording counts if a reasonable person would read it as a request to stop, and you have at most ten business days to honor it. One confirmation text is allowed if it carries no marketing. The FCC adopted new opt-out rules in FCC 26-67 on September 30, 2026; they take effect 30 days after Federal Register publication, which had not happened as of October 3, 2026, so they are not in force. Either way, act on any clear request to stop the same day.

Clinics. A recall reminder that a patient is due for care is not a reactivation offer. Keep reminders free of marketing, and send promotions only to patients who gave written consent to marketing messages, within your HIPAA obligations.

A four-week sequence

Three or four touches over a month, then stop. The timing is practice, not a tested cadence.

Week one, email, to everyone not opted out:

Subject: Your furnace is overdue for its yearly check

Hi Paul, we last serviced your furnace in fall 2024, and it missed its check last year, so it is overdue before the cold arrives. Reply with two days that suit you. If you have moved or used someone else, just tell us and we will update your file.

Dana, office manager

Every email carries your street address and an unsubscribe link.

Week two, text, only to people who agreed to marketing texts, naming your business in the first text:

“Hi Kendra, it’s Maya at Linden Hair Studio. It’s been a few months and I’d love to see you back. I have Thursday at 6 or Saturday at 11. Reply with one, or STOP to opt out.”

Week three, a live call, only inside the 18-month window or with written permission, within the hours above:

“Hi Kendra, this is Maya at Linden Hair Studio. You used to come in every six weeks, and I wanted to see if you’d like to book or if something changed. If you went with someone else, that’s fine. I’d just like to know why.”

Week four, a last email with an offer matched to why they left. A Journal of Marketing study of one US telecom company’s 2006 to 2014 data found offers combining a discount with a service upgrade won back the most customers, and that those who had left over price stayed longer once regained, though they may be less profitable than those who left over service. It is one subscription business, so take only the direction: a modest discount plus something extra for a price leaver. For someone who left after a bad visit, our practice is a fix and an apology rather than a coupon.

After that, move non-responders to an email newsletter sent once or twice a year, and stop chasing.

Ask for referrals, and the gift limits for clinics

This is not legal advice; confirm with counsel before rewarding anyone for a referral.

In Nielsen’s 2015 survey of more than 30,000 online consumers in 60 countries, 83% said they completely or somewhat trust recommendations from friends and family, the most trusted of 19 ad formats. That is stated trust, worldwide. In a 2011 peer-reviewed study of about 10,000 customers of a German bank, referred customers were worth at least 16% more than similar non-referred ones and, after controls, about 18% less likely to defect at any point in time, from a small baseline: after 33 months, 82.0% of referred and 79.2% of non-referred customers were still active.

When and how to ask

Ask at a moment of plain satisfaction, and name a kind of person rather than “your friends”:

“I’m really glad the back is moving better. If anyone at your work is dealing with the same thing, would you give them my name? Here’s a card with the front desk number.”

Tag the referral source in your software when the new customer books, or you will never know who sends you people.

Clinics that see Medicare or Medicaid patients

The HHS Office of Inspector General’s policy statement on gifts of nominal value interprets “nominal value” as no more than $15 per item and $75 per patient per year in total, never cash or cash equivalents. Gifts within those amounts need not fit an exception to the beneficiary inducement penalty; larger gifts likely to influence a patient’s choice of provider must. Treat $15 and $75 as a safe threshold, not a cap. A general-purpose debit card is a cash equivalent; a gift card redeemable only at certain stores is not. Rewarding patients for referring others may also raise Anti-Kickback Statute questions this guide does not cover. Private-pay-only practices fall outside the OIG policy, though state rules may apply. Law firms and other licensed professions should check their bar or board rules first; we did not research those.

Measure retention in stages

One retention number hides where customers are lost. Count each stage from records you already keep.

Stage	What to count	Owner
First visit to second	New customers who return within one service cycle	Front desk lead
Rebooked at checkout	Visits that leave with the next one booked, per staff member	Each provider
Plan attachment and renewal	Plans sold per eligible visit; renewals out of plans due	Office manager
Lapsed list	Customers past their return date, and how many are in the sequence	Office manager
Win-back	Lapsed customers contacted who book within 60 days	Office manager
Referrals	New customers tagged as referred	Front desk lead
Opt-outs	Opt-outs per message sent, by channel	Whoever sends

In our practice, a rising opt-out count is the first sign we watch for that a sequence is too long or too frequent.

The weekly review

Same morning each week, owner and desk lead together:

Rebook rate by staff member last week, and who needs a word.
First-to-second rate for customers who started last month.
Plans sold, and renewals due in the next 30 days.
The lapsed list: who is in the sequence, who replied, and why they left.
Every opt-out received, confirmed as processed in every tool.
New referred customers, and who sent them.
Returning guests identified by name last week, and new sign-ups with consent recorded.

Salons and studios live on the first two rows, home services on plans, restaurants on returning identified guests.

Questions owners ask about keeping customers

The legal answers below are not legal advice; confirm with counsel.

Is it really five times cheaper to keep a customer than to win a new one?

No source we could trace shows it. HBR’s 2014 article names no study for its 5 to 25 times, and Ipsos Loyalty researchers called the five-times claim a myth.

Does keeping 5% more customers raise profits 25% to 95%?

Not as a rule for local businesses. The range is stated in a 2000 summary about e-companies with no method, and the Bain brief HBR links says “more than 25%” in financial services.

How soon should a salon rebook a new client?

Before the client leaves, because the first-to-second visit is the step that slips most. Boulevard’s 2023 platform data (vendor data) shows average salons converting 45% of first visits to a second against 70% for the top tenth.

Can I text past customers a discount to win them back?

Only those who gave prior express written consent to marketing texts, to be safe. FCC rules require it for autodialed marketing texts, Florida, Oklahoma and Maryland add their own rules, and a coupon code can make a reminder promotional.

Can I call old customers whose numbers are on the Do Not Call registry?

Yes for a live call within 18 months of their last purchase or 3 months of an inquiry, unless they asked you not to call. After that you need signed written permission.

Does a “we miss you” email need an unsubscribe link?

Yes. CAN-SPAM covers commercial email to former customers, so each one needs a clear opt-out and a postal address, and opt-outs must be honored within 10 business days.

Can a chiropractic or physical therapy clinic give patients gifts for referrals?

Small non-cash gifts within $15 per item and $75 per patient per year sit inside the OIG’s nominal value threshold for Medicare and Medicaid patients. Referral rewards can also raise Anti-Kickback questions, so ask counsel first.

What should a home service maintenance plan include?

Twice-yearly visits, parts and labor discounts, and priority service, the three things homeowners in ACHR News surveys said they wanted, plus a plain line on what it does not cover.
