Currently we invoice finance charges once a month (on the first). Our invoices are due on receipt but we do give a 30 day grace period. I have several clients who will pay 45 days or so late. If the client pays on say the 20th of the month and 45 days late, when I go to assess the finance charge on the 1st of the next month the invoice is now marked paid and so no finance charges come up. That invoice (if paid 45 days late) should have at least 15days of finance charge on it but because it is marked paid on the the 1st of the month it does not come up. How do I assess finance charges on invoices that are now paid but were paid late? Quickbooks Desktop (doesn't seem to have a late charge option)
