Hi there, @MajidBashar.

You can create a single invoice for the amount of $2400. Then, record a partial payment of $400. This way, it connects the payment transaction to the original invoice.

After you enter the invoice, follow these steps to create a partial payment:

1. Click +New and then Receive payment.
2. From the Customer dropdown, pick the name of the customer.
3. From the Payment method dropdown, choose the payment method.
4. From the Deposit to dropdown, select the account you put the payment into. 
5. In the Amount received field, enter the amount your customer paid.
6. In the Outstanding Transactions section, tick the checkbox for the invoice you're recording the payment on.
7. Enter the Reference no. and Memo if needed. 
8. When you're done, click Save and close.

Additionally, you may give your customers their complete transaction history by sending them a balance forward statement.
