How do I rebook spa clients automatically?

Ask at checkout, then back it up with an automated message at the start of each guest's personal rebook window (3–6 weeks for barbershops, 14 weeks for hair colour) — automation alone recovers about 60% of guests who would otherwise drift.

Spa rebook windows differ sharply by service: barbershops 3–6 weeks, nail fills 2–3 weeks, nail full-sets 6–10 weeks, hair colour 8–14 weeks, spa courses 2–4 weeks. The automation must match the window exactly — generic monthly broadcasts underperform by 40%+.

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.
