Will my customer receive a pro-rated refund when they cancel their subscription midway?
Yes, if you’ve enabled Automatic Refunds. Zoho Billing calculates and issues a prorated refund automatically when the subscription is cancelled, based on the refund method you’ve configured. If Automatic Refunds isn’t enabled, you’ll have to raise a credit note for them manually or make a partial refund through the payment gateway which they used to make the payment.
