Summary
Promotional Credits can be applied to all the upcoming invoices, both “recurring” and “one-time” charges.

For example, If an upcoming invoice that is in due for a customer is in HK dollars and the promotional credits are in USD.
Follow these steps to deploy the promotional credits:
Change the currency of the promotional credits to match the invoice currency
Void the existing invoice and create an invoice with the same currency as that of the promotional credits
Record payment (offline) against the existing due invoice and deduct the same from the promotional credits
