To make a short payment, use the "Amount to Pay" field and enter the amount you wish to pay.

Click the "Reason" drop down to expand the reason options for short payment.

Select the reason for the short payment from the available options. These options can be customized based on your company requirements. In this example, we will select "Other".

You can enter a comment using the "Comment" icon to explain why you are making the short payment.

Click "Add" to save the comment and update the record.

Then, select the invoice to initiate payment.

Next, click the "Actions" button.

Then, click "Pay selected invoices".

The "Payment Preview" dialog box shows the amount being paid, and any discounts as well as the short payment. Note: There is a disclaimer that notifies you that if you are making a partial payment, the discounts may be adjusted depending on your system.

Select the method of payment from the list or, you can add a new payment method. Once your payment method is selected, Click "Make Payment".
