Balance due on 10/31 and invoiced 11/1 with “I just wanted to remind you that your invoice for $82.50 is overdue. The invoice was due 10-31-2025 and is now 1 day overdue. We want to build a healthy business relationship…” verbiage. Without exception, all my other creditors bill well in advance of the monthly invoice due date, and payments are always made timely and well before the prescribed deadline. I brought this to the vendor’s attention and they replied it was “a computer glitch” and “truly not a big deal.” I disagree, as this is the second consecutive month it has occured.
