When receiving monthly dues you can configure the invoice from your Recurring Transactions list and make changes to the information. To avoid recreating them all over again, I recommend editing them and updating the existing amounts.
Here's how:
From the Gear icon, select Recurring Transactions.
Find the template and click Edit.
In the Recurring Invoice screen, make the necessary changes.
Then for prepaid, I'd recommend setting up a deposit or retainer process for your company in QuickBooks Online. The retainer or deposit is treated as a liability to show that.
Here's how:
Select Settings , then select Chart of accounts .
Select New.
From the Account Type dropdown menu, select Other Current Liabilities.
From the Detail Type dropdown menu, Trust Accounts - Liabilities.
Enter a Name for the account (for example, Trust Liabilities) or accept the suggested name.
Select an option from the When do you want to start tracking your finances from the is account in QuickBooks? dropdown list.
