Is there and easy way to send recurring invoices for a rental, with being able to change only the rental period?

Are you run a rental equipment business? Consider having a renal management app to integrate with your QBO account.

Good morning, @candsbattery! Thank you for reaching out to the Community about your invoices. You can set up recurring invoices in your account. Here's how:

1. Select + New.
2. Under Customers, select Invoice.
3. When that window opens, along the bottom, click on "Make Recurring".
4. Enter a template name.
5. From the Type drop-down, choose Scheduled, Unscheduled, or Reminder.
6. If you would like them to be sent out for you, choose Automatically send emails.
7. Fill in other invoice information and Save.
