Subscription Billing Start Datewith Auto-Proration

Customers subscribing on different dates create scattered billing cycles, making cash flow and administration complex.

Solution

Add ability to set a billing anchor date (e.g., 1st of month) with automatic proration:

• Customer subscribes Jan 15th → Pays $15 prorated (50% of $30/month)

• Next billing: Feb 1st → Full $30/month

• All future billing on 1st of month
