You cut hair in kitchens. You set up a massage table in living rooms. You train people in their garage or the park, or you rent a room by the hour. Your work is good, and your clients like you.
But there is no sign over a door and no shop window. Nobody walks past and remembers you. If a client forgets to book, nothing reminds them, and the next person they find on Instagram gets the appointment.
This guide is for you. It shows how to keep clients coming back on time and how to get Google reviews when you have no shop, for $0.
The short answer
Write every client down from the first booking: name, phone number and the date of each visit. Learn each client's usual gap between visits. Reach out when they are due, not weeks later. Give a stamp at every visit so there is a small reason to rebook with you. And ask every happy client for a Google review the same way, right after the visit.
Key Takeaways
- Your client list is your business. Keep it somewhere that is yours, not only in your text messages.
- Each regular has a rhythm. A client who comes every four weeks and has not booked in six is the one to text today.
- A stamp card works without a shop. The client's phone number is the card, so there is nothing to carry or lose.
- You can have a Google profile without showing your home address. Google asks you to remove the address if clients do not come to it.
- Ask for reviews the same way every time, and never offer anything for one.
Why clients drift away from mobile pros
Clients rarely leave because of the work. They drift. A month goes by, they mean to text you, and life gets busy. Then a friend mentions someone else, and that person answers first.
A shop has help here. People walk past it, see the sign, and remember. You do not have that. When you are mobile, the only thing that brings a client back is you reaching them, or them remembering you.
So your two jobs are simple:
- Know who your clients are and when each one is due.
- Give them a reason and an easy way to come back.
Start your client list on day one
Most mobile pros already have a client list. It is just scattered: some names in phone contacts, some in Instagram messages, some in a booking app, some in your head.
Scattered is fine for ten clients. At thirty, people slip through. Put them in one place this week.
What to write down
Keep it short. You need:
- Name and phone number. The number is the one thing that does not change when they switch apps.
- The date of every visit. This is how you learn their rhythm.
- What you did. The cut, the color, the type of massage, the workout plan.
- One note that matters. Allergies, a bad shoulder, the dog at the door, the gate code.
You do not need a birthday, an address or a life story to start. The phone number and visit dates do most of the work.
Where to keep it
A notebook works for a week. A spreadsheet works if you open it every day. Phone contacts work if you add a line to the notes after each visit.
What matters is that you can answer one question in a minute: who is overdue? If your list cannot tell you that, it is not doing its job yet.
Bring regulars back on time
Every regular has a natural gap. A fade may last two or three weeks. A color may last six to eight. A massage client may come monthly. A training client may come twice a week.
You know these gaps better than anyone. The trick is to act on them.
Find each client's usual gap
Look at the last three visit dates for each regular. The usual time between them is their rhythm. Write it next to their name: "every 4 weeks", "every 10 days".
Reach out when they are due
Once a week, look down your list. Anyone past their usual gap gets a short, warm message:
- "Hi Maria, it's been about five weeks since your last color. Want me to hold Thursday afternoon for you?"
- "Hey James, your shoulder was doing better last time. Want to book a session before it tightens up again?"
- "Hi Priya, ready for next week? I have Tuesday at 7 or Saturday at 9."
Name a time. A specific offer is easier to say yes to than "let me know when you want to book."
Book the next visit before you leave
The easiest rebooking happens while you are still there. As you pack up, ask: "Same time in four weeks?" Many clients will say yes on the spot. Put it in your calendar, and theirs.

A stamp card without a shop
A stamp card gives clients a small, friendly reason to stay with you: "Every tenth visit, your trim is free." Paper cards work at a shop. For a mobile pro, they get lost in a coat pocket or a car.
A digital stamp card on the client's phone number solves that. There is no card to carry and no app to download. The phone number is the card.
Choose a reward that fits your work
Pick something that costs you little and feels generous:
- A free beard trim or a free fringe trim
- Ten extra minutes on a massage
- A free stretching session or a short plan for at-home workouts
- A small discount on the next visit

Two ways to give a stamp with no front desk
KANJIN (kanjin.app) is a free stamp card on the customer's phone number. It works on a laptop or a tablet held sideways, so you do not need a front desk. There are two ways.
1. You type their number. Open the stamp card on your tablet or laptop and choose Type the number. Type the client's phone number and press Give stamps. If they are new, that first stamp makes their card. Under it, there is a box to Add their email, with a box they can tick if they want to hear from you.
2. They scan your QR code. Print the free Counter poster from your back office. It comes with a small table tent, which fits in a kit bag. At the end of the visit, open the stamp card on your tablet or laptop, choose Customer scans, and press Ready for the next customer. The client scans the code with their own phone and types their number, and the stamp goes on their card. They can add their own email there too, so you do not have to type it.
| You type their number | They scan your QR code | |
|---|---|---|
| What you do | Type the number, press Give stamps | Press Ready for the next customer |
| What the client does | Says their number | Scans the code, types their number |
| Who types the email | You, in Add their email | The client, on their own phone |
| Good for | A quick stamp as you pack up | Clients who like to do it themselves |
One honest note: a scan only gives a stamp after you press Ready for the next customer. A scan at any other time does not. That is on purpose. The code is printed, so a stranger who finds it cannot give themselves stamps.
If your poster prints without a QR code, switch on the shared customer card in Settings. It is free.
What your client gets
When a client adds an email, the free plan sends their card link and stamp count after their first visit. They can open the link any time to see how close they are to the reward.
Get Google reviews without a shop
Many mobile pros think Google is only for businesses with a storefront. It is not.
A Google profile without a public address
Google has a setting for businesses that go to their customers. Google calls these service-area businesses. Its help page says: if you don't serve customers at your business address, remove your address from your Business Profile, and enter your service area instead.
A few things Google's page says about service areas, as of November 2026:
- You can set up to 20 service areas, by city, postal code or other area.
- You cannot set a radius around your home.
- Your overall area should not go much past about two hours of driving from where you are based.
So your home address stays private, and clients nearby can still find you. Read Google's own page before you set it up: Manage your service areas.
Ask every happy client, the same way
Once your profile is live, ask for a review the same way with every client. A good moment is right after the visit, when they say "this is great."
Try: "I work on my own, so a Google review really helps people find me. Can I text you the link?"
Google does not allow you to offer anything in return for a review, and it does not allow you to ask only the clients you think will be happy. Ask everyone, offer nothing. The stamp is for the visit, never for the review. Google's rules are here: Google's review policy.
To print a small card with your review link and a QR code, use the free Google Review QR Code Maker. For more on the first reviews, read How to get your first Google reviews.
Let the ask go out on its own
Asking in person works, but clients forget once you leave. With KANJIN, the free plan sends Google review requests by email.
It works like this, from the product as of November 2026:
- A request goes only to a client who left an email and ticked yes to hearing from you.
- By default, it goes out an hour after the visit.
- Each client is asked once, and then not again for at least a year.
- You add your Google review link in the back office first.
The address question: a PO box is fine
Every marketing email has to carry a postal address. In the US, the FTC's guide says a post office box registered with the US Postal Service is allowed: CAN-SPAM guide for business. Canada's email law asks for a mailing address too. So KANJIN asks for one before it sends any email for you, including review requests.
Many mobile pros do not want their home address in a client's inbox. You do not have to use it. The back office says it plainly: "A PO box is fine." Add it once in Settings, under Shop details, and your emails can go out.
What is free, and what is PRO
Everything in this guide is on the free plan, with no time limit:
- The stamp card on the phone number, with no app for clients
- Typing a number on your tablet or laptop, or the QR poster and table tent
- Google review requests by email
- Emails to clients who said yes
- Downloading your client list whenever you want
PRO is $29 a month per shop. It adds automatic emails, such as a note to a regular who is later than usual, a birthday email, and a reminder when a client is one stamp from the reward. It also removes the monthly limit on review requests, and it lets you import a client list you already keep in a spreadsheet. On the free plan, clients go on the list as you stamp them. You do not need PRO to do anything else in this guide.
Common mistakes
- Keeping clients only in your messages. When you change phones or apps, they go with it. Keep one list.
- Waiting for clients to book. The client who is two weeks overdue is not gone yet. A short text often brings them back.
- Asking only your favorite clients for reviews. Google does not allow it. Ask everyone the same way.
- Offering a discount for a review. Google does not allow that either. Keep rewards for visits.
- Putting your home address on emails. Use a PO box instead.
Frequently asked questions
Can I run a stamp card if I go to my clients' homes? Yes. A stamp card on the client's phone number needs no shop and no front desk. You type their number on your tablet or laptop, or they scan a printed QR card with theirs.
Do my clients need to download an app? No. With KANJIN, the phone number is the card. Clients who add an email get a link to see their stamps in the browser.
Can I be on Google without showing my home address? Yes. Google's help page says to remove your address if you do not serve customers at it, and to set a service area instead. You can set up to 20 areas.
Do I need a business address to send emails to clients? Every marketing email must carry a postal address. A PO box is fine, so your home address can stay private.
I rent a room by the hour. Does this still work? Yes. The stamp card follows the client's phone number, not the room. If you move rooms or start visiting clients at home, nothing changes for them.
Your next step
This week, put every client in one list with their last three visit dates. Then text the three who are most overdue.
