Turn finished visits into reviews and rebookings: an n8n follow-up workflow, JSON included

Description and use

An n8n workflow sends a follow‑up message 20‑30 hours after a visit, asking for a review or offering a rebooking date, boosting engagement and repeat bookings.

Problem

Salon owners struggle to send timely follow‑up messages after a visit, leading to missed opportunities for reviews and rebookings.

Outcome

The workflow guarantees one timely message per visit, increases review and rebooking rates, and keeps each run lightweight by processing only visits in the 20‑30 hour window.

Workflow

• Schedule trigger every 12 hours
• Read completed visits from a Google Sheet
• Code node filters visits in 20‑30 hour window, determines visit type, calculates next rebooking date, builds message
• Send node (placeholder for WhatsApp, SMS, or email)
• If node splits first‑time vs regular visits
• Log nodes record review_sent or rebook_sent for analytics

Evidence

The workflow needs to know how often each treatment comes back. That knowledge usually lives with the senior stylist and nowhere else.

Source

The fix is boring and effective: a workflow that runs every 12 hours, picks the visits that ended 20 to 30 hours ago, and sends exactly one message.
