Recurring invoices

1. Create and approve the first invoice as usual.
2. On the invoice, click Make recurring.
3. Choose how often (weekly, monthly, quarterly or yearly), the date of the next one, and when to stop: never, after a number of invoices, or on a date.
4. Choose whether each new invoice is approved automatically and whether it's emailed to the customer.

Your schedules are listed under Sales → Recurring invoices, where you can pause, edit or run one now. If a schedule can't create an invoice, the bell lets you know.

The same works for bills you pay every month: see Recurring bills.
