How you know you have it
“How do invoices go out, and how do you chase slow payers?”
What kind of leak it is
A time leak — it costs hours
How to measure it
time per invoice cycle × invoices per month × 12, plus chasing time separately
Annualized the same way everywhere: duration × frequency × people × 52.
Typical range — illustrative
30–120 hrs/yr
An order of magnitude to prime your eye, not a statistic and not a claim about anyone's result. The only number that matters is the one you measure.
The move — Automate
Auto-send plus a reminder sequence.
