In the Vietnamese market, this concept interacts tightly with Zalo OA reach, VND cash/QR payment mix, and the district-cluster dynamics of competing venues. Applied properly it can move 5–15 points of 90-day cohort retention.
PEKO operationalises this concept as part of the loyalty layer that runs alongside the venue's existing booking system (Booksy, Fresha, Mindbody, KiotViet, or paper) rather than replacing it.

FAQ
Which Vietnamese verticals does add-on conversion apply to?
Best fit for barbershops, nail bars, hair salons, spas and beauty salons. Verticals where rebook discipline and the guest-stylist relationship drive most of the revenue.
How long does implementation take?
With PEKO, a small venue typically goes live in 3–5 days: contact import, Zalo OA connect, basic reminder cascade switched on, then tuning over the first 2–3 weeks.
Do I need to replace my current booking system?
No. PEKO is positioned as a loyalty layer on top of existing booking systems. Booksy, Fresha, Mindbody, KiotViet or paper diaries all stay; PEKO adds retention on top.
