I've got you covered, @homebody1.

If you receive an invoice on the 4rth day and it's due on the 10th day of the same month, you can manually calculate the discount and enter it as a negative amount.

Here’s how:

1. Go to the Lists menu, then select Customer & Vendor Profile Lists.
2. Click Terms List.
3. From the Terms dropdown, press New.
4. Name the payment term, then choose either Standard or Date Driven.
5. Enter the discount as a negative amount.
6. Press OK After.

Check out this reference to learn more about payment terms in QuickBooks Desktop: Set up payment terms.

Once everything is good, you can now use the payment term you’ve set up when creating customer invoices and vendor bills in the program.
