Brief this module

This module is available as a standalone build or as part of a full stack. Price range is for the module alone — combined builds are scoped together.

What it is

Cal.com configured for your service structure, wired to Stripe for deposits, and connected to n8n for automated follow-up. No per-booking commission. No monthly platform fee.
