i have an invoice that is the same every month. Rather than inputting it 12 times, can I just put it in once for every month?

The recurring invoice feature is unavailable to QuickBooks Self-Employed (QBSE), Helen.

This option is only available to QuickBooks Online (QBO) Essentials, Plus, and Advanced subscriptions. To utilize this functionality, you can consider switching from QBSE to QBO.
