How are my prepaid credits applied to invoices?

Prepaid credits are applied to invoices on a first-in, first-out basis. This means that the oldest prepaid credit will be used up before any other payment is applied. When an invoice is paid with prepaid credits, the client’s balance of available credits will be automatically adjusted and updated accordingly. When multiple payments (including prepaid credits) are made on an invoice, the prepaid credits will be applied first before any other payment is applied. If there is not enough prepaid credit to cover the full amount of the invoice, then additional payment methods will be used to cover the remaining balance.
