Hello there, Shaharyar.
I agree with, Rainflurry. I'm here to share more information about it.
Once you create an invoice, the transaction will automatically be posted on the default accounts. If you want to use a different Accounts Receivables account, you'll have to add a separate transaction.
I've added this link as your guide in managing Accounts Receivables and Accounts Payables: How to group Accounts Receivable or Accounts Payable account types.
When everything is in place, you can utilize this article for future reference: Reconcile an account in QuickBooks Online. This link can walk you through the steps in matching your accounts effectively.
In case you have other concerns or questions about supervising your accounts, tag me in your reply. I’d be more than happy to work with you again.
