Can I make the General Ledger Account to be on Credit in sales Invoice entry

Thank you for taking the time to visit the QuickBooks Community, ylian!

When you say "on Credit", do you mean to post on the CREDITS side of the accounting journal?

An invoice will create a transaction journal in the background, where the Accounts Receivable is posted on the DEBIT side and the income account assigned to the invoice item is posted on the CREDIT side. You can check this by clicking More on the Invoice page and selecting Transaction Journal. Therefore, yes, and it's the income account that will be posted on the CREDITS side.

On the other hand, let me add these articles to guide you with paying your invoices:
