Let me provide you more information about this, charterbooks.
You can set up invoice terms to apply early payment discounts to your customers. However, discount amounts are not automatically calculated. You'll have to update the invoice and include the discount.
Here's how:
Go to the Sales menu at the left pane, then choose the Invoices tab.
Locate the invoice that was already paid but with a remaining balance.
On the lower left of the invoice, click Discount Percent, and change it to Discount value.
Enter the early payment discount amount, then click Save and Close.
