I’m a private tutor / fitness instructor and I need an automated system that creates PayPal invoices from my Google Calendar events at the end of each month. What I need built: I want a solution that: Reads events from Google Calendar Filters only billable sessions (based on title, tag, or calendar) Calculates: Total hours per client Rate per client Currency (ZAR for local, USD for international) Generates monthly PayPal invoices automatically Emails invoices to clients via PayPal Runs automatically at month-end (no manual exporting) Data setup Each calendar event contains: Student name Session duration Optional rate override Client details (email, rate, currency) can live in: Google Sheets or Script configuration Tech preference Google Apps Script preferred PayPal Business account Open to Zapier / Make if cleaner Clean documentation required Deliverables Fully working automation Setup instructions (Google + PayPal) Error handling (missed events, duplicates) Short Loom video walkthrough Timeline 5–10 days preferred Fixed price (open to suggestions)
