I have an existing invoice and i recived an amount from that invoice but its not the total how can i adjust the invoice

Let me help you in recording this transaction in QuickBooks, @jobet1979.

Since the payment amount does not matched to the invoice, we can simply open it back to modify and matched it based on the amount you've received.

Here's how:

1. Open the invoice. (You can also use the Advanced Search feature and filter it to easily locate the invoice.)
2. Double-click the amount for the line item to edit it.
3. Enter the amount your customer paid on you.
4. Click Save.

If in case you need to correct an invoice that is already marked as paid, you can still open it and changed its amount based on the actual payment you've received. Let me show you how:

1. Open the paid invoice.
2. Double-click the amount you wanted to update.
3. Enter the correct amount and click Save.
4. Click OK.

You can also use the Invoices and Received Payments report to review your invoices and the payments made by your customer. Just go to Reports menu and search Invoices and Received Payments.
