What are the ways a customer can pay for their subscription?
Zoho Subscriptions supports various payment options for a subscription. Your customer can pay via credit card, debit card, bank account and PayPal account.
If the payment option is associated with the subscription, then Zoho Subscriptions will automatically charge the customer and subscription will be renewed.
If payment option is not associated, then customer can pay using the payment link in the invoice sent to them. Or, they could pay directly pay to you via cash/check/bank transfer and you could record the payment received using the Record Payment option for that customer.
