Hi - Is there a way to enter a bill where it is paid by monthly installments, without having to enter multiple bills?

Hello there, @moss.anthony2. 

Glad to see you here in the QuickBooks Community. Let me address your concern about creating an invoice that you are paying as monthly installments.

In QuickBooks Online, recurring transaction details are base on how you create them, and there is no automatic way to do this. The reporting of monthly income and monthly sales tax will be incorrect. To get the correct amount, you can manually add the monthly rent to the invoice.

Let me show you how: 

1. Go to the Gear icon.
2. Under LISTS, select Recurring Transactions.
3. On the Recurring Transactions page, select New.
4. Select Invoice.
5. Enter your transaction details and how you want to recur it accordingly.
6. Click Save Template.

For more details, here's an article you can read to learn more about how recurring invoice works: Create recurring transactions in QuickBooks Online.
