Build this if
You sell multi-session packages and currently coordinate bookings, credits, and progress by email or spreadsheets.
A client-facing scheduling and progress portal for independent executive and life coaches, replacing email coordination with a single hub for sessions, packages, goals, and notes.

Decision snapshot
You sell multi-session packages and currently coordinate bookings, credits, and progress by email or spreadsheets.
You only run single one-off sessions with no package tracking or your clients expect a full CRM with marketing automation.
Five coaches each onboard three paying clients onto packages and complete at least ten booked sessions through the portal without manual email scheduling.
Problem and target customer
Independent coaches lose hours each week to email back-and-forth for scheduling, package tracking, and goal updates, and have no shared place where clients can see session history, remaining credits, or progress between meetings.
Solo executive and life coaches running their own practice who bill through session packages and need a professional client portal without building custom software.
Monthly subscription for coaches, with a small per-booking transaction fee on paid sessions.
Editorial note
CoachCal connects coach availability, package credits, client booking, private notes, and milestone updates into one reviewable session loop. The first release keeps payment and video calls outside the core so the coaching relationship remains visible and easy to test.
CoachCal: Executive & Life Coach Session Hub addresses a specific operating gap: For operators managing appointments, availability, and service intake, the product provides one reviewable place to move appointments, availability, and intake details from configure coachcal availability to run the operator schedule without losing ownership, evidence, or failure state. Start with the smallest record, owner, evidence, and outcome loop; integrations should support that loop rather than become a second source of truth.
CoachCal: Executive & Life Coach Session Hub uses bookings / month as its operating unit. Variable cost is mainly driven by transactional email, payment processor; keep those charges separate from the infrastructure baseline.
For CoachCal: Executive & Life Coach Session Hub, Run a small set of real appointments, availability, and intake details through the complete flow and measure whether the target operator reaches run the operator schedule without the current manual handoff. This gives the team a concrete way to judge whether the workflow earns a broader feature set.

Deliverables and acceptance
Recommended stack
Lovable for the coach and client portal UI
Supabase Postgres for clients, sessions, packages, credits, and goals
Resend or SendGrid for booking confirmations and reminders
Stripe for package payments and per-booking fees
Railway for background jobs and scheduled reminder sends
Lovable ships the dual coach and client portal quickly, Supabase gives relational storage for the credit ledger and session history, Stripe handles package and per-booking payments, and Railway runs the scheduled reminder jobs that email alone cannot guarantee.
