To avoid this, you can generate hosted payment pages via the [API](/billing/api/v1/#Hosted-Pages_Create_a_subscription) and pass the customer’s customer ID, if they’re already a customer in Zoho Billing. This way, when an existing customer subscribes to a new plan with the same information, they will not be created as a separate customer in Zoho Billing. * * *
