Free loyalty program and back office for nail studios

The next set is already in their calendar. Make it easy to come back to you.

Gel and acrylic sets need an infill every 2 to 3 weeks. That short cycle is your strength, and it is easy to break.

Short answer

Is there a free loyalty app for a nail studio?

Yes. KANJIN (kanjin.app) gives a nail studio a digital stamp card on the customer's phone number, with no app for them to download, no limit on customers and no time limit. The free plan also sends up to 20 Google review requests a month and one email a month to as many as 150 customers, everyone asked the same way. The paid plan is $39 a month per shop and is never needed to run the card.

The infill cycle

Clients drift to the cheaper studio

A new studio opens two streets away, with infills $5 cheaper.

Your client tries it once, between two of your appointments.

If the set looks fine, they simply do not rebook with you.

On a 3-week cycle, two missed infills is six weeks of income gone without a sound.

35

days, then Slipping away

KANJIN uses 35 days for a nail studio. That is about two missed infills, before a client settles in somewhere else.

Should you match the cheaper studio’s price?

Taking $5 off every infill costs more than most owners expect. Enter your price, the discount and your margin, and compare it with giving a few free extras to the clients who come most often.

To break even on that discount you need 40% more customers than you have today. Not more sales: more customers, every month the discount runs.

For what that discount costs you each month, you could give 952 free visits, one each to a creator who posts about you.

A percent discount comes straight out of profit. Your food cost does not fall when you cut the price. So a 20% discount costs 20% of sales, not of margin. A free visit costs only what you hand over: $8.40 of ingredients, not the $28 menu price. We assume the discount does not bring in more sales.

An example

Cutting $5 off every infill

A studio does 60 infills a week at $45.

Cutting $5 off every one costs $300 a week, or about $1,300 a month.

A nail art upgrade every 8 visits costs about $3 in product and 10 minutes.

Sixty visits a week earn 7 or 8 upgrades, so about $22 a week in product.

The price cut goes to everyone, including clients who were never leaving. The reward goes only to clients who keep returning.

Stamp card

Stamp the infill, reward with art

8 stamps earn a free nail art upgrade.

Infills are the visit that keeps a client yours, so stamp each one.

Eight infills on a 3-week cycle is about 6 months.

Nail art costs minutes and a little product, and clients show it off.

What nail techs ask us

  • “Most of my bookings come through Instagram messages.”

    Keep booking there. KANJIN stamps the visit while the client sits at your table. It does not take bookings.

  • “My techs are self-employed.”

    Paying your team, in the back office, compares commission, table rent and hourly pay. It shows for nail studios at no cost.

  • “Clients lose paper cards.”

    There is no paper card to lose. The stamps sit on the phone number they give.

The whole thing, start to finish: the poster, the first customer, the first stamp and the reward.

Nail studio questions

How do I stop nail clients going to a cheaper studio?
First, know who is late. The Stamp card screen shows each client’s last visit. After 35 days they move into Slipping away, while there is still time to reach them.
Can I give a free infill after 10 visits?
Yes. You set the stamps, from 3 to 20, and you write the reward. Stamps go on from the client’s phone number at the desk.
Can I ask only my favorite clients for Google reviews?
No. Choosing who to ask is called review gating, and Google does not allow it. KANJIN asks everyone who left an email and agreed, in the same words.
Which nail services make the most money?
Profit by item is in the free back office. It plots each service by margin and by how often it is booked. It shows which to promote and which to price up.
