Free loyalty program and back office for pet groomers
Six weeks between grooms, and no paper card survives it.
Most dogs need a groom every 6 to 8 weeks. The owner books the slot, but the dog is the real regular.

Short answer
Is there a free loyalty app for a grooming salon?
Tied to the pet
The coat grows back on time. The booking does not.
The breed and the coat set the groom cycle, not the calendar.
Owners forget until the dog is matted, then call whoever has a slot.
Nervous dogs settle better with a groomer they know, and owners notice that.
Losing one owner can mean losing two or three dogs at once.
75
days, then Slipping away
Grooms are spaced far apart, so KANJIN waits 75 days before an owner shows under Slipping away. That is more than a month past a 6-week groom.

Stamp card
One card per phone number, any number of dogs
6 stamps earn a free nail trim or teeth clean.
The card follows the owner’s phone number, not the dog.
An owner with two dogs fills it twice as fast, which most groomers accept.
For one card per dog, give each dog its own number at the desk.
Six grooms on a 7-week cycle take about 9 months.

An example
A doodle on a 6-week cycle
A full groom for a doodle costs $95.
Every 6 weeks is about 8 or 9 grooms a year.
That is roughly $800 a year from one dog.
A free nail trim after 6 grooms costs about 10 minutes of your time.
Over 5 years, one dog brings about $4,000 in grooms. A missed rebooking is worth a friendly note.

about 4 years
Losing 25% of 200 regulars costs you about $9,000 of gross profit a year. Keeping just one in ten of them is worth $900 every year, without one new customer.
These are gross profit, not takings: what is left after the cost of what you sold, before rent and wages. A customer who leaves part-way through a year is counted as half a year, which is the honest average.
Groomers ask us
“I work alone from a van.”
That works. The stamp card runs in the browser on your phone, so no counter is needed.
“My booking tool already sends reminders.”
Keep those. KANJIN is for owners who never booked the next groom at all.
“Will a review request annoy nervous owners?”
It goes only to owners who left an email and agreed. Each owner is asked once, then not again for a year.

Pet grooming questions
- How often should a dog be groomed?
- Many coats need a groom every 4 to 8 weeks, and your groomers know each breed best. KANJIN only needs the visits. After 75 days with no stamp, the owner shows under Slipping away.
- Can grooming clients earn a reward for referring a friend?
- On the paid plan, yes. A new customer names who sent them, and that person gets a stamp.
- What does the review request email say to pet owners?
- By default it thanks them for the visit and links to your Google listing. It offers nothing in return, because Google does not allow that. You can edit the words on the Reviews screen.
