Thanks for posting your question in the Intuit Community, info181,
Let me share information on how to link lump sum payment to multiple invoices.
In your case, we can use the Receive Payment feature. Here's what you'll need to do:
Once done, if the bank account is connected into your QuickBooks Online account, then you can add and match the downloaded payment transaction to the multiple invoices.
For additional reference, I'm including some helpful articles that you can check:

Thanks for sharing your concerns in this conversation, @KA2022.
You can create an Accounts Payable account for the transaction and create a journal entry to post the total amount of the payment.
Then, make another journal entry transaction to post the advance payment.
Here's how to create an Accounts Payable account:
Here's how to create a journal entry to post the total payable amount in the account you've just made:
Then, record the Advance payment on the Accounts payable.
Once done, you can check out the register of the Accounts payable you've created to track the payment.
For the monthly payment, follow Step 3 when recording. Check out this link to learn more about entering details in a journal entry in QuickBooks Online.
I've also added this article to help you categorising and matching your transactions in QuickBooks Online.
Let me know if you have any follow-up questions. I'll be around to guide you some more. Thanks again for trusting us with your business.
@katherinejoyceO : if you don't mind me saying so, it is best to avoid using Journals - for the average user, they are difficult to understand - much better to use the 'standard' transactions we're all used to.
@KA2022 the easiest way to create an advance payment (deposit) is the same way you would create a payment against an existing invoice (Bill).
Go to https://app.qbo.intuit.com/app/billpayment select the customer name & enter the amount (if you have existing bills for this customer de-select them). In the Ref no. field, enter the cheque number or BACS or leave blank. In the Memo field maybe enter a comment that it's a deposit against XYZ.
You'll notice that a message "This transaction will create an additional credit in the amount of £xxx" appears in the bottom left.
When you later enter the supplier's bill it will be unpaid.
Return to the above transaction, or select Pay Bill, and this credit will be available to pay the supplier's bill in QB.
Hope this helps.
