Welcome to the QuickBooks family, @Anonymous.
I can share what I know about entering sales transactions in QuickBooks Online. Right now, splitting a single invoice and payment into two different months is currently unavailable.
The only way I can think of to separate them is by receiving the payment twice with different dates. It would also be best to seek expert advice from an accountant about what's the best way to handle this type of situation.
We take your ideas as a guide on which area of the product we should enhance. Iβll send feedback on your behalf about this feature for consideration in future updates.
To keep you in the loop about the latest features being rolled out, visit the QuickBooks Blog page.
I've also included an article you can use to handle invoices, like how to record partial payments, as well as finding the remaining balance: Record invoice payments in QuickBooks Online.
Please know that I'm just a post away if you have any other questions. Have a great day ahead.
