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.
Inside Zalo, a venue's own ordering or loyalty screen is called a Zalo Mini App.

FAQ
Which Vietnamese verticals does zalo oa broadcast 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.
What can the PEKO AI Agent do?
It turns a plain-language request into a ready voucher, customer segment, campaign, loyalty rule, menu or points change. You review and approve; nothing goes live without you.

Birthday trigger
An automated message and offer sent in the week before a guest's birthday. Conversion rates of 18–28% on a single send make it the highest-ROI evergreen automation for beauty venues.
Answer
How do you automate repeat visits without spamming customers?
Automate the trigger, not the calendar. Messages fire on individual behaviour (a lapse, a birthday, a nearly complete reward) with frequency caps and a quiet period so no customer hears from you twice in a week.
Term
No-show rate
Share of booked appointments where the guest fails to arrive without cancelling. A 12%+ no-show rate is the dominant drag on service-venue revenue and is usually fixed with deposit-on-booking + 24h + 2h reminders.
