How much time needs to pass for an A/R account to be considered delinquent?

Always a good question, and one I have been asked quite often in interviews throughout my career. A delinquent account is 90 days of the due date.

This question is a very straightforward one, as the industry standard is usually 90 days. This question is testing your very basic A/R knowledge. Feel free to expand on your response, showing that you are aware of different credit terms for various clients.

"From my experience, a delinquent account is 90 days; however, I have some clients with shorter credit terms who pay their invoices every 30 days, and some every 180 days. Is 90 days the average for our accounts here at Company ABC?"
