Welcome to the Community, Mostafa. I'll explain to you the purpose of the Journal entry.

Journal entries record a business's financial transactions, including sales, expenses, and payments. They offer a structured method for monitoring the flow of money, ensuring precise financial records, and supporting informed decision-making.

It is part of the General ledger and is used to maintain the balance and track all financial transactions.

Journal entries are used to manually adjust accounts and correct account balances when necessary. For example: If you realize your inventory account balance is incorrect after a physical count, you can use a journal entry to correct it.

For you to get the exact amount of your sales, you need to identify all your Revenue sources.

Once identified, you can run a Sales report. Here's how:

1. Log in to your QuickBooks account.
2. Navigate the Reports in the left corner of the screen.
3. Use the search bar and type in a relevant report name.

You can select any of the available sales reports to run.

Afterward, total your revenue sources from the report to calculate the exact amount of your sales.
