Which transaction type is NOT allowed to be made recurring in QuickBooks?

The reasoning behind the fact that a credit memo is not allowed to be made recurring in QuickBooks lies in the nature and function of credit memos. Credit memos are typically used to provide a credit to a customer for returned goods or overpayments. They are usually unique transactions created as needed, reflecting specific customer situations that require individualized attention. This variability means that making them recurring would likely lead to inaccuracies or misunderstandings, as the conditions under which a credit memo is issued can differ from one instance to another.

In contrast, transactions like general journal entries, checks, and expenses often have a more standardized nature and can benefit from being set up as recurring. For instance, monthly rent payments or utility bills are consistent expenses, making them ideal candidates for automation through recurring transactions, hence streamlining the accounting process.
