The honest framing: AI is mostly a targeting and timing improvement over rules-based automation, not a replacement for the relationship work. The best operators combine AI for the long tail (lapsed-by-1-week regulars) with human calls for the top decile (lapsed VIPs).
In Vietnam specifically, Zalo OA is the dominant retention channel — read rates of 60–80% beat SMS (15–25%) and email (8–15%) by a wide margin. Any retention playbook that does not put Zalo OA as the default channel underperforms by 2–4×.
PEKO operationalises this as a loyalty layer that sits on top of an existing booking platform — Booksy, Fresha, Mindbody, KiotViet, or paper diaries — rather than replacing it. Onboarding for a small venue typically takes 3–5 days from contract to first automated message.
FAQ
How long does implementation take?
Small venues typically go 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).
How fast will I see results?
Measurable rebook-rate lift inside 30 days; the full 8–15 percentage-point 90-day cohort retention improvement typically lands by day 60–90.
The PEKO ecosystem
PEKO and LOOP are two products from the same company. PEKO is the AI retention layer and runs alongside the POS you already use. LOOP is the AI-native POS that covers operations: recipe-level inventory, staff shifts, table plans and the kitchen display. Each works on its own, and run together they share one dataset, so nothing has to be entered twice. See PEKO + LOOP in one ecosystem

Answer
AI customer retention for F&B in 2026 — complete guide for cafés, restaurants, and chains
AI customer retention in 2026 = per-customer cadence churn detection + AI-personalised Zalo OA messages + send-time optimisation + dynamic RFM. Operators who deploy all four lift repeat rate by 15–25 points and beat rule-based programs by 2.3–3.1× ROI.
Answer
AI loyalty platforms vs old-school points cards — what's the real difference?
Points cards reward all behaviour equally and pay margin to guests who would have returned anyway. AI platforms spend retention budget only on guests whose silence is statistically aberrant — typically 3–5× the ROI on the same spend.

Four use cases carry the return: per-customer churn prediction, personalised message drafting, send-time optimisation, and segmentation that refreshes nightly instead of monthly.
