How do I enter transactions in a bank account or cash book

Hello there, joseph2410.

I'll ensure you can enter transactions in your QuickBooks Online (QBO) account.

In QuickBooks, there are multiple ways to enter and track transactions. You can create a sales form, like an invoice, sales receipt, and other transactions, in the +New button to capture the entire business cycle, and it also gives you the most flexibility and features.

You can also add transactions manually while you're working on your account. It saves time if you're reviewing your chart of accounts and need to make a quick addition. 

Here's how to manually add transactions to an account.

1. Go to Transactions and select Chart of Accounts.
2. Find the account you want to review or add transactions into.
3. On the account page, select the Add journal entry, Add deposit, or Add cheque dropdown at the top of the list.
4. Select the type of transaction you want to add.
5. Fill out the fields to complete the transaction.
6. Then, hit Save.

I'm just a post away if you have clarification or additional queries about handling transactions in QuickBooks.
