Three-week refill cycle. PEKO never lets it slip.
Nails are a 3-4 week conversation. PEKO is the loyalty layer that times Zalo OA refill nudges, birthday gel-sets, and add-on art reminders — without touching whatever booking tool you already use.
Your booking tool keeps the calendar.
PEKO doesn't compete with Fresha, Booksy or your in-house spreadsheet. We add the AI brain: who's about to drift, who's worth a VIP nudge, and who'll convert on a 25%-off gel art voucher this week.
Sits alongside
Three pains quietly bleeding
Walk-ins outnumber bookings 3-to-1
Most VN nail salons take more walk-ins than online slots. PEKO captures them at the chair via QR receipt — no app to install — and pulls them onto your loyalty roster.
Paper stamp cards lose 40% of clients
Lost card = lost client. Digital stamps on Zalo + PEKO refill reminders push 8-week retention by ~35%.
Add-on revenue is invisible
Gel art, French tip, foot massage — you sell them but can't see who buys what. PEKO tracks add-ons per client and resurfaces the right upsell next visit.

FAQ
Will this work if I use paper appointment book?
Yes. Most VN nail salons start on paper. PEKO works with paper, spreadsheet, or any booking app. We only need the client list + last visit date.
Do clients need to install an app?
No. Loyalty lives on Zalo OA, which 95%+ of VN clients already have.
