What does dunning mean?
Dunning is the practice of persistently demanding payment of a debt, most commonly through repeated letters, emails, or notices sent to a debtor who has failed to pay on time. The term belongs chiefly to the world of commerce and accounting, where businesses rely on a structured dunning process — a sequence of increasingly firm reminders — to recover overdue invoices without resorting immediately to legal action. The word is usually found in fixed phrases such as 'dunning letter', 'dunning notice', or 'dunning procedure', and in modern subscription-based services, automated dunning emails are triggered whenever a customer's card is declined. Its connotation is one of insistent, methodical pressure rather than outright hostility, though excessive dunning can be perceived as harassment. The term derives from 'dun', a 17th-century verb meaning to demand payment insistently.

The word 'dunning' traces back to a 17th-century debt-collector's pest named Joe Dun — so relentless at chasing debts that his very name became the verb.

Etymology of dunning
Dunning derives from the verb 'dun', meaning to demand payment persistently, which appeared in English in the early 17th century. The traditional account holds that the verb arose from the name of Joe Dun, a notoriously tenacious London bailiff of that era whose name became proverbial for debt-collecting zeal, although this folk etymology is not definitively proven and some lexicographers treat the verb's ultimate origin as uncertain. The gerundial form 'dunning' followed naturally as the practice became formalized in commercial correspondence.
