Edge cases worth checking
When customer acquisition cost is unusual
Revenue, gross margin, and service cost stay constant during payback. Double-check this input before relying on the result.
When additional monthly service cost is uncertain
Churn, expansion revenue, discounting, and shared overhead are excluded. Run a lower and higher value to see a useful range.

Do not rely on one customer acquisition payback scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
