Square is strong on payments + calendar in the US; weaker on Vietnam-specific channels and language. PEKO is the local retention layer that sits on top of Square (or any booking system), not a calendar replacement.
Comparator framing: pick the tool that owns the layer you actually have the biggest problem in. Calendar problems → booking platform. Retention problems → loyalty layer. Vietnam-channel problems → local-first retention layer with Zalo OA + ZNS native.
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
Are paper stamp cards still worth using in 2026?
Only for pure walk-in venues with no repeat business to defend. Paper redemption runs under 15% versus 35–55% for digital, and paper leaves you with no way to contact a customer who stops coming.
