dear, i want to ask a quesiton about the prepayment by customer. My client usually buys a prepaid service which allows him to consume later within a year. As a result,  he pays me the whole money now and will consume it in the future. i followed the instructions step by step from https://quickbooks.intuit.com/learn-support/en-us/help-article/service-items/record-retainer-deposit.... but it failed always. how can I record it when I receive the money from the client and spend money later by the cunstomer? thanks very much.
