Editorial disclosure: I work at Zellbox. Fresha described from their product page as of August 2026. Bridging setup varies by plan.
Fresha is a free salon + spa booking + POS platform with a large marketplace. Zellbox adds WhatsApp reminders on top for customers who respond better to WhatsApp than Fresha’s built-in SMS.
How it works
- In Fresha → staff member profile → Calendar sync → copy the .ics subscription URL.
- In Google Calendar → Other calendars → Add → From URL → paste the .ics URL.
- In Zellbox → Onboarding step 2 → connect the destination Google Calendar.
- Every Fresha booking now propagates → Google Calendar → Zellbox WhatsApp reminders (24 h + 2 h).
For real-time (fewer than the iCal poll’s few-hour delay), use a Zapier bridge if you can pull Fresha booking events via their API.
What Zellbox adds beyond Fresha’s built-in reminders
- WhatsApp channel — Fresha sends SMS + email natively, but WhatsApp isn’t a first-class option inside Fresha itself; the Google Calendar bridge is what makes a WhatsApp reminder possible without leaving Fresha’s marketplace.
- Higher delivery rate in WhatsApp-first customer segments — salons serving customers who ignore SMS or email tend to see meaningfully higher open rates once reminders move to WhatsApp.
- Signed consent PDFs for aesthetic or wax services — the signed PDF attaches to the customer record automatically, useful for treatments where a consent form is standard practice.
- Two-way replies land in your Zellbox inbox — when a customer replies to confirm or ask a question, the message shows up next to that customer’s record instead of on a staff member’s personal phone.
Setup notes for marketplace-driven salons
iCal poll delay vs the API/webhook route
The per-staff .ics feed Fresha exposes is a subscription Google Calendar polls every few hours — fine for the 24h reminder, but a same-day rebooking through Fresha’s marketplace may not show up in time for the 2h reminder. If your salon gets a lot of last-minute marketplace bookings, a Zapier bridge off Fresha’s API keeps that window tighter.
Where Zellbox fits next to Fresha’s marketplace
Fresha already owns discovery, payment, and POS for marketplace-driven salons — Zellbox isn’t replacing any of that. It’s specifically adding the WhatsApp reminder channel for the slice of your customer base that ignores Fresha’s SMS/email but reliably reads WhatsApp.
