One client, as many policies as they have. Each policy gets its own row in the sheet and its own first-payment reminder in GHL.
Connection settings
Writes each policy into your Policy Sales Tracker sheet.
v7: everything (sheet, GHL contact, custom fields, booking, reminders) flows through the single Apps Script endpoint. Reminder timing (2 days before due) is handled server-side + by the GHL workflow — nothing to configure here.
