What is overdue invoice?

An overdue invoice is an invoice that has not been paid by the due date specified in the payment terms.

Overdue Invoice explained

Overdue invoices are the most common cash flow problem for freelancers. 85% of freelancers have been paid late, and 21% experience late payments more often than on-time. The longer an invoice stays overdue, the harder it is to collect. Best practice: send a reminder at 3 days past due (friendly), 7 days (firm), and 14 days (escalation). Most overdue invoices are not malicious — clients simply forget or lose the email.

Example

A $3,000 invoice was due April 1. It is now April 20 — 19 days overdue. The freelancer has sent one manual reminder (day 7) but heard nothing back. An automated reminder system would have sent follow-ups at day 3, 7, and 14.
