Service businesses (clinics, salons, agencies) lose 10–25% of revenue to no-shows. Reminders cut that in half; auto-rebooking captures the rest.

1Cal.com webhook → n8n Webhook node on booking created.
2Calculate two timestamps: appointment - 24h and appointment - 1h.
3Use Wait Until nodes (or write rows to a 'reminders' Sheet polled by a Schedule Trigger).
4Twilio SMS at T-24h: 'Confirm or reschedule' with two reply keywords.
5Twilio SMS at T-1h: short reminder + location/Zoom link.
6Post-appointment workflow: read Cal.com attendance status; IF no-show → send 'Sorry we missed you, here's 10% off to rebook' with a Cal.com link.
7Log every reminder + outcome to Google Sheets for show-rate reporting.

Skip the setup — download this workflow and import it into your n8n instance.
