Aging

Also: accounts receivable aging · AR aging

Outstanding money grouped by how overdue it is — not yet due, 1–30 days, 31–60, 61–90, over 90.

The total tells you how much. The aging tells you whether you have a billing problem or a collections problem, and they are not fixed the same way.

Money in the over-90 bucket is qualitatively different from money that came due last week. Every week it sits there, it gets less likely to arrive.

What it means for a small course

Two courses owed the same total can be in completely different trouble. Look at the shape, not the sum.

Fairway is built by people who had to learn all of this.
